Cinnamon Crumb Cake Keto Donuts

There’s nothing like the sweet scent of cinnamon sugar donuts on a Saturday morning.  But what makes these cinnamon crumb cake keto donuts so special?  The fact that they are totally gluten-free and low-carb!stack of low carb doughnuts

Keto Donuts…or is it Keto Doughnuts?

No matter how you spell it, these low-carb donuts are amazing!  Just 1 carb per serving! And they’re so easy to make, because these keto donuts are baked, not fried.  Horray for much less cleanup involved!

This recipe makes about a dozen doughnuts, depending on the size of your donut pan.  If you are looking for one, let me recommend this nonstick donut pan.

They are nonstick, which is a big bonus, especially when it comes to keto baking.

Ingredients for Keto Donuts

Almond Flour

Like most of my keto baking recipes, these donuts start out with good, old almond flour.  Almond flour is one of the best grain-free alternatives to all-purpose wheat flour. It’s practically a pantry staple for folks following a ketogenic diet.

For baking, I like to use an almond flour made from blanched almonds with a super-fine ground texture.

And, if you don’t use almond flour as frequently as I do, you can store it in your refrigerator or freezer to keep it fresher, longer.

Coconut Flour

Coconut flour is a high fiber flour that is super useful in gluten free, grain free and low-carb baking.

But because of its high-fiber content, baking with coconut flour can be a bit tricky.  Coconut flour absorbs liquid like crazy — so recipes using coconut flour tend to have a higher ratio of wet ingredients like eggs, coconut milk, or water.

Just like with almond flour, your coconut flour will stay fresher longer if you store it in the refrigerator or freezer.

Flax Meal

Gluten-free flours can often require thickeners or binders such as xanthan gum.  But in this recipe, I skipped xanthan gum in favor of a tablespoon of flax meal.  Flaxseed meal gives this keto donut recipe added nutrition and a delicious nutty flavor — and it also acts as a natural binder.

How To Make Keto Donuts

Making donuts is easier than you might think – especially if you’re baking them instead of frying them. (I mean, fried doughnuts are insanely delicious! But they’re a bit too much of a hassle for a non-morning person like me.)

First, we make the donut batter, and then we make the crumb topping (which is arguably the best part!)

To make the batter, mix all the dry ingredients together.  Then, in a separate bowl, mix all the wet ingredients together.  Pour the wet ingredients into the dry ingredients, and stir to combine. That’s it!

To make the crumb topping, mix some almond flour, sweetener, and salt with softened butter. Using your fingertips, sprinkle the crumb topping over the donuts. No need to pack it down!

Tips for Better Low Carb Donuts

Here are a few tips to ensure that your keto donuts turn out soft, fluffly, and delicious.

  1. Make sure your ingredients are at room temperature before baking.  To bring eggs to room temperature quickly, place them in a large bowl of very warm water for a few minutes.
  2. Use fresh baking powder.  Baking powder makes these donuts rise — so you want to double check that your baking powder is active. To test if your baking powder is still active, place a teaspoon of baking powder in a bowl and pour 1/4 cup of boiling water over it. It should bubble up right away. If it does, it’s still good.
  3. Fill each ring of the donut pan 3/4 of the way full. If you fill it too much, the batter will overflow, and you won’t have a hole in the middle of your donut. If you don’t put enough batter in, you’ll end up with flat donuts. (Still tasty though, obvs.)
  4. Let the donuts cool in the pan.  Gluten-free batters — and especially keto batters — are tender and crumbly when warm.  So, it’s best to let the donuts cool in the pan before removing them.  I find that the room temperature (or just slightly warm) donuts have better flavor, too.
  5. You can store these donuts wrapped tightly at room temperature for a couples days — but honestly, they’ve never lasted that long at my house!

  10. Hi. I made these last night, and while they were great, I just am not a fan of the coconut flour taste. Is there a reason why it has coconut, or could I just use almond flour?

    • You could try to use all almond flour, but the amount used and the resulting texture will be different. If you experiment with it, let me know how it goes.

    • I think either would work, but it’s more important that you get the correct ratio. Like, Serve is a 1:1 swap with sugar. Sometimes other keto sweeteners are a 2:1, so you’ll want to check your particular brand.
