Why this recipe is so awesome
Reader Reviews
“These are by far the best keto muffins I have ever had. so many keto muffins are dry or fall apart easily, these are firm and super moist. I made these to take to a quilt retreat where there will be loads of non-keto items, but these will do triple duty as breakfast, a snack or dessert!” — Bonnie B.
“These were amazing! Only trouble is, they’re TOO good – Be careful not to eat them all in one sitting 🙂” — Gail
“My son said he wouldn’t have guessed they were keto. My “anti-keto” husband has been eating them without complaint!! And my picky daughter packs one every day in her school lunch. I normally don’t like keto baked goods made with almond flour because of the texture, but the texture of these muffins is really good! I did process the dry ingredients together in my blender, just to make sure the almond flour was very finely ground. Another winner from Carolyn, my favorite keto food blogger!” — Becky

Ingredients needed:
- Zucchini: This is a wonderful recipe to use up some fresh zucchini. You can grate it with a box grater or a food processor.
- Almond flour: These are almond flour zucchini muffins and they won’t work with coconut flour. For a nut-free option, you can substitute with sunflower seed flour.
- Sweetener: I like Swerve Granular in these keto blueberry muffins but any sweetener should work. The consistency does not rely on using a particular brand or kind. But allulose will likely make the tops brown a little more quickly.
- Cocoa powder: I prefer Dutch process cocoa for its deeper chocolate flavor.
- Protein powder: Like many of my other keto cake recipes, I use unflavored whey protein to help it rise and be more fluffy. You can also use egg white protein powder or pea protein powder. Do not use collagen as it will make things gummy and hard to bake through.
- Cold coffee: Coffee enhances and deepens the chocolate flavor of baked goods, so I recommend it for these keto chocolate donuts. You can replace it with plain water if you prefer.
- Dark chocolate chips: You will need sugar-free chocolate chips for this recipe. I like to use ChocZero. You can also use homemade sugar-free chocolate chips.
- Kitchen staples: Eggs, vanilla extract, avocado oil, baking powder and salt.
Step-by-step directions
- Grate the zucchini and place in a sieve in the sink. Sprinkle with 1/4 tsp salt and toss to combine. Let drain 1 hour, then squeeze out as much moisture as possible.
- In a large bowl, whisk together the almond flour, sweetener, cocoa powder, protein powder, baking powder, and the remaining salt.
- Stir in the eggs, oil and zucchini until well combined. Stir in the coffee or water, and stir until well mixed. If your batter is very thick, add a little more liquid, one tbsp at a time, until it reaches a thick pourable consistency.
- Stir in the vanilla extract and 1/3 cup of the chocolate chips. Divide the batter evenly among two muffin pans with 16 silicone or parchment paper liners. (If you do not have two muffin pans, you can do this in batches, or you can bake the remaining muffin batter in greased ramekins).
- Sprinkle the tops with the remaining chocolate chips. Bake at 350ºF for 25 to 30 minutes, until the muffins have risen and the tops are firm to the touch. Remove and let cool complete in the pan.
Expert tips
These delicious keto dairy-free muffins are super easy to make. Be sure to check out the video in the recipe card! Here are my best tips for getting it right:
- Take the time to drain your zucchini very well. I show you in the video how much moisture I manage to squeeze out of mine. It’s a surprising amount!
- How much liquid you need to add to the recipe depends on a number of factors: your almond flour, your cocoa powder, and how well you managed to drain your zucchini. You want a batter that resembles cake batter.
- This recipe makes more than the standard 12 muffins. You may even get as many as 18 muffins. If you don’t have a second muffin tin, you can work in batches. Or you can put the batter into greased ramekins or mini loaf pans.
- Always save some keto chocolate chips for the tops of the muffins, as it makes them look more inviting. I used ChocZero for mine.
Baking with zucchini
Zucchini really is a wonderful addition to so many baked goods. Even if you don’t like zucchini on its own, chances are that you will enjoy it in muffins, cakes, and other treats.
You can see how I used it here in this Keto Lemon Blueberry Cake, as well as in some delicious Keto Zucchini Bread. It’s even delicious in these Zucchini Spice Waffles!
Because zucchini doesn’t have a strong flavor on its own, it lends itself well to being a “hidden” vegetable. It adds moisture and increases the nutrition of baked goods, but it doesn’t take over.
The best way to prep zucchini for baking is to grate it. You can do this in a food processor with a specialized blade, or you can simply grab a box cheese grater and do it by hand.
Zucchini also needs to be salted and drained, and then squeezed out. This helps to reduce the excess moisture so that your baked goods aren’t soggy. There’s no need rinse your zucchini after this, as the amount of salt is insufficient to make your cake or muffins salty.

Is there a low carb alternative to the zucchini? It doesn’t grow well in my area. Would carrots be too high in carbs?
Thank you for all the wonderful recipes you post for us!
Carrots would be relatively high carb, yes. Try just skipping it and adding maybe another tablespoon of liquid?
Again, another fabulous muffin recipe! Will definitely make again..and again!
Thank you so much!
These are really nice muffins. I made them with water and whey protein, and they came out perfect. I had exactly 200g of grated zucchini, but I think that after squeezing, the amount was more like one cup than 1.5 cups. That said, I came out with exactly 16 muffins. This is a definite keeper recipe.
I rarely comment on recipes but this one is definitely a keeper! They are delicious, just made them and tried, my favorite muffins now. 🙂 Can’t wait for rest of the family to try them! I did substitute avocado oil with coconut oil and sweetener with monkfruit sweetener one and they turned out great!
The hardest part is the waiting for them to cool so we can eat them. They look and smell amazing. I need to get additional silicone liners as I only had twelve. So I over-filled these a bit and ended up with twelve. Too bad! Kidding! Could share, but what’s a few additional carbs, cause I don’t share well. This is the second zucchini recipe I have made this week. The lemon glazed cake was great. Thanks for another winner!
I finally got around to making this, and LOVE it. I could not find any Lily’s chocolate chips in my stash, so I took a Lily’s dark chocolate bar with almonds, and chopped it lightly with my nut chopper. I didn’t use coffee, just water. Otherwise, I followed the recipe perfectly. One warning, I should have mixed it better, because toward the end of scooping in the batter, it had gotten pretty liquidy. Those muffins turned out a bit weird, separated, but still quite tasty. The others were nicely blended and sticky throughout.
Good to know about the separating. It’s a big batch so yes, if not mixed well and thoroughly, you can get some weird batter at the bottom.
Does whey protein powder sub for the egg white protein powder?
Yes, you can do that.
What oil do you recommend to substitute the avacado oil? I can’t wait to try this recipe 🙂
Any oil works.
What if you don’t have protein powder go the recipe????
They don’t rise as well.
these are simply delicious!!! just made them, took out of the oven and let cool (for not very long) added a pad of butter and holy holy yummy!!!
and i have to say, i have been a follower for a few years and i totally and truly appreciate not just the recipes but the reason ‘why’ when reading through the posts
thank you so very much for all you do and share. i for, and my wife for two, truly appreciates all you do to make our keto lifestyle so much easier
Love your recipes. Just wanted to ask a question about weighing out almond flour either in grams or ounces. I sometimes have a problem with my cup of flour either being too much or too little for the recipe. I know you post some things in grams but could you post grams for the almond or other flours you use in your recipes. I would love mine to turn out better.. Thank you
There are a lot of recipes I still need to go back and do that for. But if you want to weight almond flour, it’s about 100 to 105g per cup. Anywhere in there would be fine.
Hi Carolyn,
These look amazing! Can I use Cacao powder instead of cocoa powder in this recipe?
I find cacao harder to mix in but it should work well enough.
Just made these wonderful muffins. Rich, chocolatey goodness. Delicious! Thank you for a great easy to follow recipe!
So good! Thanks for the great recipe! These freeze very well.
Hi! thank you for the great reciepe.
what can i replace the sweetner with if i dont have it available?
plus, any protein powder will work here?
Any protein powder except collagen protein will work. I don’t know what sweeteners you have wherever you are so I can’t really advise there.
These were amazing! Only trouble is, they’re TOO good – Be careful not to eat them all in one sitting 🙂
