Low carb and grain-free, these keto chocolate fudge crumb bars are my healthy answer to Starbucks’ oatmeal fudge bars. A delicious sugar-free dessert you won’t want to miss.
I first published this recipe for keto fudge bars back in 2015 and they have remained a favorite ever since. I decided it was time to revisit the recipe and make them even lower in carbs. At less than 6g total carbs, you can enjoy them any time!
Keto Starbucks Copycat Recipe
I used to be such a Starbucks aficionado. It’s funny but I don’t go at all anymore unless I am traveling somewhere and in desperate need of a decent coffee. I much prefer to make my own coffee and specialty coffee drinks at home.
Or maybe I have just become THAT anti-social.
I also used to love quite a number of the Starbucks baked goods, and for obvious reasons, I don’t eat any of those anymore. I do love to make my own ketofied versions, however. They give me plenty of inspiration!
I do believe that the first keto Starbucks treat I ever made were my Maple Pecan Scones. Those were one of my all time coffee shop favorites, but the real ones used to leave me with a bit of a stomach ache. I’ve also got keto versions of the Mini Vanilla Bean Scones and the famous Cranberry Bliss Bars. All just as delicious and not nearly as likely to cause tummy aches or blood sugar spikes.
And who didn’t love the oatmeal fudge bars, with their delicious crumbly crust and rich chocolate filling? These Keto Chocolate Crumb Bars are just the thing to satisfy that craving.
How to make Keto Crumb Bars
Of course, those of us following a keto diet aren’t likely to be using oatmeal in any of our baked goods. So how does one replicate that same crumbly, buttery crust?
You will be happy to hear that it’s not that hard. Done right almond flour can make a great crumb crust for keto baked goods. It really comes down to the right ratio of almond flour, sweetener, and butter. I always like to add in a bit of coconut flour too, to dry out the mixture and make it more crumbly.
The filling is simply keto chocolate ganache with a little added thickener. It’s like chocolate sauce when you pour it over but it becomes a thick, delicious fudgy layer as it bakes.
Can you make these dairy-free?
You can indeed! Simply swap out the butter for some coconut oil or palm shortening.
For the filling, you can make the ganache with coconut milk but do know that it’s thinner that way and you may want to add a bit of cocoa powder or additional glucomannan to help thicken it up a bit more.
Then simply proceed as directed in the recipe.

hi these look amazing! I wonder if instead of the ganache you can use Keto ‘Nutella’ or chocola almond butter?
Carolyn says
Absolutely! Here’s my homemade nutella recipe: https://alldayidreamaboutfood.com/homemade-low-carb-chocolate-hazelnut-spread/
Linda says
Gonna make this today and swirl the rest of the caramel I made yesterday( from the caramel brownie bites-yum)
After the chocolate. Carolyn, you are amazing and the author of some of my most favorite things. I hope you feel appreciated 🥰. I also made the lemon bar bites yesterday and the curd is easy and delicious. So happy with everything I’ve made with your recipes.
Carolyn says
I LOVE that idea!

Thanks I am from Rwanda in East Africa
Mark says
I made these today and they’re excellent! The filling was so wonderfully fudgy and the crumb crust and topping were very tasty. A very satisfying dessert!
Anu says
No surprise that this is RIDICULOUSLY good, thank you soooo much! I love that this is totally scalable so I don’t have to make a full batch unless I need to, stealthy portion control 🙂 I used a combination of erythritol, stevia and monk fruit sweetener in the crust and crumble, and powdered allulose in the chocolate fudge filling, I find my palate prefers a balance of different sweeteners and this also works out cheaper in the UK where Swerve is really expensive. I’d love to try this with a mix of ground almonds, walnuts, and pecans, they go so well with chocolate. Thank you again, Carolyn, another winner!
Dianna says
Made this recipe over the weekend & delighted how easy to make!! Definitely another winner!! I was amazed how the chocolate ganache turned out. Thank you for sharing this fudgy delight with us!!! Your baking tips & videos are great & so beneficial for successful outcomes!!
Gretchen Roberts says
These were so good! My 9 yr old daughter helped me make them yesterday because the family wanted to have s’mores, and I wanted something that I could enjoy with them. This was perfect! It is so nice to have a treat that is easy to make, worth it, and doesn’t set me off on a sugar-binge like traditional sugar treats tend to do. I feel in control and like I have options now like I haven’t for years. Thank you for sharing your talents (and I’m looking forward to baking for Christmas with your Ultimate Guide to Keto Baking book!)
Radina says
I would love to make these but is there any substitute to xanthan gum?😍
Carolyn says
Glucomannan works.
Jen says
I’m obsessed with these bars! Such a great way to indulge without having the guilt to go along with it.
Ashley F says
These came out so good! Firmed up perfectly and was so tasty! A huge hit!
Matt Taylor says
These look so amazing and keto as well. Sign me up! haha
Jenny says
Would this ganache filling firm up even if it wasn’t baked, like perhaps by setting in the fridge for awhile? I am thinking of modifying the recipe with a chocolate toping instead but I don’t want the filling to be gooey.
Carolyn says
Hi sorry, just saw this. It’s a bit thinner than my other ganache recipes but yes, it should. Or you can search ganache on my blog and find some other variations.
