Prize winning keto donut recipe? Okay more like keto recipe battle winning. If you’ve ever seen the fun and hilarious High Falutin’ Low Carb on YouTube, you know what I am talking about. He takes two similar recipes from low carb bloggers and tries them both out, on camera.

And then of course he declares a winner. He’s an absolute hoot to watch so I highly recommend seeking him out. It’s all done with good humour and good grace.

Honestly, I had all but forgotten about these delicious keto cinnamon donuts, since I originally wrote the recipe back in 2012. But his recent video brought it back into my sights and I decided to have a go at it again myself and do my own instructional video. So you can see first hand just how delicious and easy they are to make.

How to make brown butter

Brown butter. Just the very words are enough to send shivers of delight down my spine. I love butter as it is, but there is something about heating  it to the point where it becomes nutty and fragrant that is pure heaven.

It’s incredibly versatile too. You can use brown butter in savory dishes, on fish, chicken, or vegetables. Combined with some lemon and capers, or some crispy sage leaves, and that brown butter sauce will have you running your fingers across your plate, trying to get every last drop into your mouth.

Like my Brown Butter Chicken with Sage and Prosciutto, a simple dish that comes together in minutes and tastes like it came from a fancy restaurant. Or as the base for my Keto Cream of Mushroom Soup, giving it an unparalleled depth of flavor.

But it’s also wonderful in sweet dishes too. It has a rich, almost caramel-like flavor that’s good in cookies, cakes, and frostings. I’ve used it my popular keto blondies, as well as in the glaze for a low carb pumpkin layer cake.

Browning butter is incredibly easy. Simply place it in a saucepan or skillet over medium heat and watch it carefully, as it can burn if you’re not paying attention. For 1/4 cup to 1/2 cup butter, it usually only takes 4 to 5 minutes to achieve a rich amber color.

The froth from the butter can sometimes obscure the color, making it hard see if the butter is properly browned. Just get a spoon in there and push some of the froth aside. You can also swirl the pan a bit if the butter is browning unevenly.

Remove it from heat as soon as you see that rich color, as it can burn very quickly after that.

How to make keto donuts

The baking pan:

Thank goodness for donut pans! It’s made a world of difference for those of us who can’t, or don’t want to, eat the sugary high carb variety.

I highly recommend the donut pan from USA Pan, as it’s incredibly non-stick and your keto donuts will practically fall right out of them. Yes, it is pricier than most, but you are paying for durability. I have learned in my many years of baking that quality matters. Purchase a ten dollar pan and you will likely be tossing it in a few years when it everything starts sticking. Purchase a good pan and it will last you forever.

The keto flour:

Keto donuts can be made with any number of low carb flours. My Keto Chocolate Donuts are made with coconut flour and it’s one of my most popular recipes. I’ve also made keto donuts with a combination of almond and coconut flours, and I’ve even made some donuts with hazelnut flour.

This particular donut recipe is made with almond flour, and they are light and fluffy, and absolutely delicious. To be honest, they are good enough on their own. But then that brown butter glaze takes them to new heights.

The keto sweetener:

You guessed it. You know me, I am a big fan of Swerve and their powdered sweetener is beyond compare, in my opinion. I will tell you that I think you should use Swerve for this recipe, especially in the glaze as it helps give it the right consistency.

If you want other options, your best best are BochaSweet or Lakanto. Do be aware that Lakanto powdered sweetener is 2x as sweet and so you need less of it, which will make your glaze a lot thinner.

Also, BochaSweet powdered sweetener is very clumpy so break it up before you try to make the glaze. You also may find that your glaze is softer and thinner as well.

The protein powder:

Yes, it is a critical ingredient. I wouldn’t add it to a recipe if it wasn’t. Gluten is a protein and in its absence, another dry protein helps baked goods rise and hold their shape.

Every time I skip the protein powder, I regret it. Don’t do it! But you can sub egg white protein instead.

The brown butter glaze:

Be patient here, friends, and let that brown butter cool properly before adding it to the glaze. You will regret it if you rush the process as the glaze will clump up and then separate.

You want the brown butter to be just cool to the touch but still liquid. Then slowly drizzle it into your sweetener, whisking constantly. The mixture will be thick until you add the cream. Then it should become a thick frosting that you can spread on your donuts.

If you would prefer a thinner glaze, just add a little more cream.

There yo have it, my friends. An updated version of my delicious Keto Cinnamon Donuts with Brown Butter Glaze. You are going to love them!

      I came home and found these as my daughter is on the ketogentic life style program.
      To my surprise I have to say OMG, as good if not better than any donut I’ve ever eaten.
      Thanks

  5. Ok… now normally I’d be skeptical with the whole low carb donut thing (should those words be in the same sentence?) but then you snuck in the brown butter glaze and, well, when you add brown butter, you can do no wrong.

    Reply

    • You know what? I was never much of a fan of donuts, but once I started making my own low carb version, I fell hard. And it’s so fun to tell my kids they get donuts for breakfast…they look so happy!

      Reply

    • I’ve never used powdered stevia but I know it’s potent stuff. I wouldn’t use more than about 1/4 tsp, if that.

      Reply

  11. I made a few modifications to make them dairy-free:

    I used Jay Robb Egg White Protein Powder (chocolate was all I have on hand) instead of Whey. I used coconut oil instead of butter in the donut batter. I used homemade ghee (I already had some browned) and coconut milk for the frosting along with a few drops of stevia (in addition to the powdered erythritol).

    They turned out wonderful except for the part where I didn’t grease my donut pan and they stuck to the bottom. 🙂

    • Wow you made the already! And oops on the donut pan…I’ve done that more times than I’d like to remember.

  13. I know you wouldn’t get the “donut effect” if you didn’t use a donut pan, but can you see this working … in a muffin pan, for example? I just can’t bring myself to buy another piece of equipment that I will use only in a blue moon. Looks yummy.

  14. We were just talking about donuts yesterday, so we are definitely going to give these a try. They look delicious.

  15. That’s it. I’m going out today to buy donut molds. Maybe even minis just for fun. Or maybe I’ll get reeeeaaaallllly crazy and buy both! But THIS is the recipe I’ll make 🙂

    Reply

  19. Carolyn, I had a dream about these last night! I swear I did. I saw your post last night on FB with the photo of these donuts, and I swear I could not get them off my mind…so I ended up dreaming about them. :/ Girl’s gotta eat! 😉

    Reply

  20. I’m curious to know (and maybe this is somewhere on your site, but it’s 9:47pm and I want to make something NOW to take to an amusement park tomorrow!)….but how does the Swerve measure out compared to other sweeteners? Is it measured the same as sugar (1/4 sugar is replaced by 1/4 cup Swerve)? I’d have to use Splenda, and the white and brown Splenda’s are measured out differently…..I’d love it if in your recipes you include what the comparable amount of sugar would be so we can easily swap in our own sweeteners.

    Reply

    • Swerve can be used cup for cup like sugar. But splenda won’t work very well for the topping, I don’t think.

      Reply

    • Sure. But keep in mind that hazelnut meal usually isn’t as finely ground so your donuts may be a little less smooth looking.

      Reply

  23. I made these 2 days ago, and my husband has declared them to be his favourite gluten & grain-free treat yet! I made them in a mini bundt tin, and 8 cakes took 18 mins to bake. They really were delicious, the only problem I had was the icing turned out a little gritty. Any suggestions?

    Reply

    • Hi Holly, what kind of powdered sweetener did you use? I think maybe a little more cream would have helped a bit. Here’s a suggestion….mix the powdered erythritol and cream before adding the browned butter. I think it might dissolve better that way.

      Reply

  24. I made these in a regular sixed muffin tin. The recipe as-is made 6 muffins and they took approx 22 mins to bake.

    I do not have liquid stevia so I used liquid splenda – have no clue as to the conversion so I winged it – used a little more than 1/4 c worth of sweetener (about 18 drop liquid splenda)

    They were good but not sweet enpugh on their own w/out the icing.

    The icing was not my favorite – the swerve stayed gritty and had a cooling effect (although def not as pronounced as my regular erythritol) I did use the confectioners swerve. I don’t think I care for the taste of so much erythritol, I find it gets bitter and burns my tongue and mouth when used this way, in this quantity. next time I may try adding powdered isomalt and polyd to my butter on the stove, melting it then adding the swerve and letting it melt completely, then take off heat and add cream. it may be more praline-like but the crystalization is not good to me. The taste itself was good – Just the after taste/mouth feel of so much erythritil. I must be sensitive to it!

    I will def make the donut recipe again and play with the icing… I will have to try the other technique of dissolving the swerve in the cream first as well. Also Iwonder if I cool the browned butter in the fridge before I add to the swerve if that will prevent recrystalization.

  25. Just made these after thinking about them for days. So, so, so good. I’m new to making donuts, and these were more dense than I expected, but still so very good. Will be making these again!

    Reply

  26. I knew these would be good, but I’m STUNNED at *how* good! This was my first attempt at a baked good since going low-carb and wheat-free, and I have to tell you, with recipes like this one to alleviate a donut/cake/sweet craving, I honestly don’t see any reason why I would need to have a traditionally-made donut ever again. I *so* appreciate your efforts with these recipes… they really make me feel like this can absolutely be a permanent lifestyle for me, with no need to “cheat”!

    Reply

  27. I made these tonight because I wanted something not chocolate or cheesecakey & hoped the kids would like. My eldest hates most of my sugar-free baking, so I was determined to make this recipe a little sweeter. I added some extra erythritol equivalent to a 1/3 of a cup, added 10 drops of maple extract along with vanilla extract & some extra cinnamon.

    The glaze is not done yet, these babies just came out of the oven. My eldest tried a quarter & is asking for more! My toddler is a little harder to please though….

    Winning recipe, will make these for an upcoming toddler birthday party. Carolyn, how do you come up with all these fantastic recipes??

    Reply

    • Phew, when I read the first part of your comment, I thought they weren’t going to have made the grade! I have no idea how I come up with these, they just pop into my head and I do them. I have a long list of things I want to make and there isn’t time enough in the world for me to make them all!

      Reply

  28. Oh my! I made these donuts this afternoon! What a treat they are.
    I did make a few changes… Used egg substitute and used Liquid splenda in place of the stevia. I used 18 drops for the donut part of the recipe. For some reason the stevia leaves me with a terrible after taste. Don’t know why…
    I added 10 drops of liquid splenda to the Glaze. Only had to use 1 tablespoon of heavy cream.. It was perfect!
    My DH had one and he did just fine with blood sugar control… He has been a type I Diabetic since he was 12 years old. Now 58 years old. He keeps extremely tight control of his blood sugar and so far the recipes I have tried from you site have been just fine for him. FYI…. his last A1C was 5.3
    He has not had a donut since he was a little boy. Haha… He licked the bowl of the glaze!

    Reply

    • How wonderful! I am so glad for your husband that these worked out well. His A1c is fantastic! And I am so glad that one of my recipes gave him a chance to have donuts again.

      Reply

  29. Just made these! I subbed plain whey protein powder and upped the vanilla to 3/4 tsp in the donuts (Sometimes the vanilla protein powder is too strong for me). My glaze doesn’t look anything like yours, but luckily it still tastes fantastic!! I just ate an entire one and swear it resembled the beloved cake donuts I used to eat every Sunday as a child. And the smell of that brown butter icing is AMAZING. I couldn’t stop smelling it. Wow! I think this is one of my favorites from your site, Carolyn. Thank you!

    Reply

    • Just made these. Again. Delicious! Best part was I tested my blood sugar before eating one…and again 2 hours afterwards. And it was a few points LOWER than when I started! The glaze smells SO good when it’s warm, I can hardly stand it! I just stand there sniffing and sniffing and sniffing…..my kids don’t really like them, but that’s fine….more for ME! 🙂

      Reply

  30. I finally made these last night. Never did brown butter before and your instructions were perfect! I want to find other uses for it! The glaze never got to be “spreadable” so I’m unsure what I did wrong there but I poured over the cooled donuts as a glaze and the butter hardened up after. Delicious!!!!!!!

    • They won’t rise very well if you don’t have some sort of additional protein, even if it’s egg white powder or hemp protein.

        Would xanthan gum work? Im new to Keto and also gluten free baking. I see xantham gum in a lot of recipes but am unsure of what it does and or replaces. Thanks!

        Reply

        • Xanthan gum helps hold baked goods together but it won’t help them rise. You really need the protein powder for that.

          Reply

  33. Carolyn – I finally got around to making these. I LOVE THESE!!!! The donut flavor, with the added vanilla whey protein, is by far better than coconut flour donuts I have made in the past. The browned butter glaze, wowee!! I tasted it before putting on the donuts, to see if it was good, double WOW! It reminds me so much of caramel that I came back to read the post and sure enough you said it tasted like caramel. I was so anxious to try the donut (even though it wasn’t completely cooled) so I put some glaze on it. Normally, I don’t like glazed donuts, or glazed anything. But this version is awesome! Now, I went back to the kitchen to add the rest of the glaze to the other 7 donuts that are completely cooled now. So, here I am waiting for another 20 minutes (glaze is starting to thicken, oh yes) for the glaze to set and will have a second donut. I am so happy I decided to try these this morning. I’m assuming I could store these (whatever is left of them) in an airtight container, but do I refrigerate them? Forget about freezing them, they will never make it to that stage.

    • I think you could have them on the counter for a day or two, probably no more than that. Glad you like them so much!

      Reply

  38. Wow! I didn’t know something “healthy” could taste this FABULOUS!!!!! And the aroma as they were baking was an appetizer like no other. My husband LOVED them. He said they’re better then what you buy then added, “they’re better then home made”….. which of course tickled my funny bone because they ARE home made. Makes me feel like a Kitchen Queen to be able to offer these to my husband and growing boys. I bought 2 donut pans and can see they will be put to good use. THANK-YOU for the inspiration and the FABULOUS recipe. Thank-you even more for doing “what you do” and blazing the way for us others who are looking into low carbing and gluten free, taking out the hard part, and handing us these golden recipes on a silver platter! May you be RICHLY BLESSED. If you decided to publish cookbooks I’d love the opportunity to purchase one! Happy Thursday to you 🙂

  39. Hi Carolyn. Could I use a bit of Bob’s red mill gf flour or peanut flour in place of the protein powder? Protein powders give me violent migraines, I think from the soy lecithin generally used as a preservative. Thanks!

    Reply

  40. Have had these pinned forever and finally took the time to make them this morning. The donuts, alone, are pleasantly and surprisingly good. I have way too many fails with almond flour recipes being moist. The icing – not so much. Too much of the cooling aftertaste for me. However, not all is lost. I have cream cheese sitting out and plan on mixing that brown butter icing, couple tablespoons at a time, into the cream cheese. I hope to salvage the brown butter concept.

    Reply

  41. Hi Carolyn, I can’t wait to make these! I think I may try substituting maple extract for vanilla in the glaze as I love maple donuts. I’ve been wondering if these along with other recipes such as your coconut raspberry muffins,coffee cake, etc. could be frozen? I’m not sure how the swerve freezes up. Thanks again,I’m going to give you credit for being able to stick to my low carb,no sugar lifestyle and continue with my passion for baking! Thank you a million times over!!!

    • I made these today and oh, they are so wonderful. My husband had to ask if these were something that I could eat too. He didn’t know, and couldn’t tell, they were low carb. Do they need to be refrigerated?

  45. Made these last night, with xylitol though, there are a couple of stores I still need to try to find Swerve, they were amazing. But when I put them in My Fitness Pal, they came out to 13 net carbs with my ingredients, I guess 9 when I subtract the sugar alcohol.

    Reply

  46. I made these and they were absolutely amazing. I used low carb chocolate Isopure protein because it’s my favourite, but the chocolate didn’t pull through, which is fine. I also used sugar free cinnamon sugar syrup (the Torani kind) in lieu of the vanilla. For the frosting, something about 7tbs of Swerve makes me think it’s too sweet. I used 3tbs Swerve powered, 3tlbs browned butter, and about 1.5tbs cream cheese to add thickness, and a splash of cream to get the spreading consistency i needed, and again a touch of the Sugar Free Cinnamon torani which complements the browned butter! I have a feeling these are going to disappear! They are amazing!

  47. I made these using baking blend. Had to add water cause consistency was really dry. Have you tried these with baking blend?

    Reply

    • I think you must have made some error if they were really dry. Baking blend would make them far dryer than almond flour.

      Reply

  48. I have never used Whey Protein Powder before. Are they all about the same, or is there something particular I should look for?

    Reply

    • If you have trouble with erythritol, you may also have trouble with xylitol and that’s the only decent sub I can think of here.

  50. As a major fan of cinnamon donuts prior to Keto, this was a true winner. I used a mini donut maker and this recipe yielded 39 pieces. It takes will power not to chow down on all 39 of them in one go. I let some non-keto friends try and they absolutely loved it….all the yummy-ness without the nastiness 🙂 The dough has good body and bite once it’s cooked. Delicious even without the glaze. Thanks Carolyn! You are definitely my go-to for my low carb recipes as have tried quite a few already.

  51. We made these today to celebrate my birthday. Awesome yumminess! We did have to let them cool a bit longer because a couple stuck to the pan in the first go round. A non-low carbing friend says he prefers these to the donut shop. These are so great, I can’t wait to sleep so I can get up and have another one tomorrow. Again, thanks so much!

    This recipe is absolutely a winner. I can’t wait to snack on them during the week. I didn’t have any powdered sweetener on hand, and was too lazy to blend some granulated, so I tried to dissolve it while the butter was browning. It worked great – but didn’t look quite like yours. This recipe, and the maple pecan scones make me feel like I’m not missing out on yummy-but-not-healthy carb breakfasts! Thank you!

    Outstanding! I made a slightly altered version of this amazing recipe. I used monkfruit/lekanto sweetener instead and only half the recommended amount and eliminated the heavy cream and forgot the vanilla. I drizzled the very light syrup on the finished donuts and it soaked it some but on the edges of the donut was crunchy, crispiness, not unlike a wonderful glazed donut. I shared with a few friends and they were blown away.

    Reply

    • I have a super non-stick non-toxic pan from USA Pans so I can use whatever grease I want. If yours is not as non-stick (and they do lose that ability slowly over time), then I recommend double-greasing. First with a solid fat like butter or coconut oil, and then a spray.

  64. If I have one weakness, it’s donuts. I’ve tried other recipes, and they didn’t come close now I’ve tossed out all my other donut recipes because no one’s can compare to this recipe. I just dusted mine in a mixture of Swerve sugar and brown sugar and they were amazing. Next time I’ll do the icing, too. Many thanks for all you do for us keto-its!
