Keto Coffee Cake
You can never have too many coffee cake recipes. As an avid coffee drinker, I always have some form of cake to pair with. If I’m not making an almond flour coffee cake or a classic coffee cake, I’m making this keto coffee cake.
What do whipped coffee, peanut butter coffee, and an iced coffee have in common? They are the perfect keto drinks to pair with this coffee cake!
Why this keto coffee cake recipe will be the perfect beverage pairing-
- Moist and fluffy. Some coffee cake can be quite dry and crumbly, but not this one- It’s so moist and fluffy in the middle, and melts in your mouth!
- Made with REAL low carb brown sugar. Ever heard of keto brown sugar? It looks, tastes, and feels like brown sugar, minus the carbs and calories!
- No fancy mixers or gadgets. All you need is one wooden spoon (or a hand mixer) to mix everything up.
What I love about this recipe is how even non-keto followers love it. It tastes like any classic coffee cake out there, and everyone will be begging for a second serving!
What goes into a keto coffee cake?
For the cake.
- Almond flour– Blanched almond flour or superfine almond flour will work. Do not use almond meal, as it will yield a more dense cake.
- Coconut flour– sifted well, to ensure there are clumps throughout.
- Baking powder– gives some rise and fluffiness to the cake.
- Salt– balances out all the other flavors in this recipe.
- Butter– unsalted butter measured in its melted state.
- Sugar substitute– Either a brown sugar substitute or another good quality keto granulated sugar substitute can be used, like allulose.
- Eggs– room temperature eggs.
- Vanilla extract– a must for any baked good.
For the crumb topping.
- Almond flour– blanched, superfine, or almond meal.
- Butter– unlike for the cake, the butter for the crumb topping must be cold.
- Brown sugar substitute– Also known as keto brown sugar, it’s a much more superior to white sugar substitutes.
- Cinnamon– what is a coffee cake without cinnamon?
- Salt– If you use salted butter, you can omit this.
How do you make a keto coffee cake?
Start by whisking together the almond flour, coconut flour, baking powder and salt in a small bowl and set aside. In a separate bowl, using a hand mixer, cream together the butter and brown sugar substitute until creamy. Beat the eggs in, one at a time, until combined, before whisking in the vanilla extract.
Next, gently add the dry ingredients into the wet ingredients and beat together until combined. In a separate bowl, beat together the crumb topping ingredients.
Now, add half the cake batter into a greased pan then half the crumb mixture over it. Add the remaining cake batter and sprinkle the crumb mixture all over the top. Bake the cake for 35-40 minutes, or until a skewer comes out mostly clean. Let the cake cool completely before slicing and serving.
Tips to make the best recipe
- Be sure to sift your almond and coconut flour thoroughly before adding it to the batter, to ensure there are no clumps throughout.
- If you use salted butter in any shape or form, you MUST omit the salt. Otherwise, you’ll find the cake having a salty flavor.
- Avoid over-baking the cake as it will continue to cook as it is cooling down.
Storing and freezing instructions
- To store: Leftovers can be stored in the refrigerator, covered, for up to one week.
- To freeze: Place slices of the cake in an airtight container and store it in the freezer for up to 6 months.

Frequently Asked Questions
The combination of almond flour AND coconut flour must be used to create the perfect cake. If you want to use one or the other, you may prefer to make an almond flour coffee cake.
Always bake your coffee cake on the middle rack to ensure the tops do not burn. If it does look like it is browning too fast, cover the top of the cake with tin oil.
As the name suggests, this cake is best served with a coffee beverage. My favorite keto coffee drinks include a salted caramel cream cold brew, a cold brew, or a bulletproof coffee.

This was the best low carb coffee cake I’ve ever made!
Used the wrong flour!
We will make this again though. It was very tasty but I think we’ll try more butter in the topping and I’ll have to try something to make the cake layer less the consistency of cookie dough
Could have been user error as we are not proficient with keto recipes yet. We’ve tried at least 25 recipes from this site and have liked them all.
I was thinking the same, or is it just cake to have with a coffee?
Cake to have with coffee 🙂
Hello!
This recipe sounds great! Could I just use almond flour for this recipe- 2 1/2 cups?
Unfortunately almond flour and coconut flour don’t measure the same. More almond flour might make it dry…Look online to see what the ratio is if you are using all almond flour. Just adding an additional 1/4 cup of almond won’t be correct.
I made it without the streusel topping in a ramekin and microwaved it for 2 minutes. It was absolutely perfect!
Hi Arman! Thanks for all of your great recipes! 😀😀
I used monk fruit in this as a sub for the brown sugar substitute…..and date paste with a little cinnamon for the filling. Turned out great ……. 🙂 yummo!
I used a loaf pan not a 9×11 because the batter was not looking like it’d be enough as stated in past comment. Plus a photo showed a loaf pan. Will update on my thoughts after this is done baking. Smells great! But the crumb topping has me a little skeptical. Lol.
Can I use all purpose flour instead of almond flour and coconut flour.
Not that I’ve tried
A big piece of this, and a mug of coffee would be perfect right now! That looks delicious! I really have to try that. 😋
Hi Linda, I used an online converter for metric.
Lovely recipe! Is there any chance you are going to put a toggle to change ingredients to metric? It is SO MUCH MORE reliable for baking!!!!
I don’t see any coffee in the ingredients.
Hi! Cake is in the oven now! Can’t wait to try it. But I ran out of cake batter? Used a 9×9 pan. Barely smoothed some on the bottom and still didn’t have enough for 2nd layer. Had to make 1/2 batch more. Any thoughts?
This definitely sounds better than some others and I want to try it soon! Which means, I must start doing a better job with my food needs. I get too lazy to do what I need. 🙁 You have some good recipes.
Great, enjoy the recipe!
