How to Make Keto Coffee Cake

Gather a few simple ingredients, mix them in separate bowls, then combine them for a deliciously rich coffee cake batter and bake to perfection.

  • Eggs – As the binding agent in the coffee cake, whole eggs hold everything together while providing structure. 
  • Butter – The fat in the butter adds a rich flavor and enhances the flavors of other ingredients like cinnamon and vanilla. 
  • Sour Cream – Adds moisture, richness, and tangy flavor to the cake. It complements the sweetness of the batter and enhances the overall taste.
  • Dry ingredients – A combination of almond flour, ground flax meal, and coconut flour makes this coffee cake low-carb, gluten-free, and grain-free. 
  • Low carb sweetener – Use keto brown sugar substitute for best results. 
  • Baking powder – Used as a leavening agent to help the coffee cake rise and become light and fluffy. 
  • Spices – Ground cinnamon, star anise seeds, allspice powder, and salt all add excellent flavor and complement the richness of the butter and tanginess of the sour cream.
  • Vanilla extract – Vanilla adds a rich note to your cake and enhances all other flavors.
  • Nuts – Adds fantastic crunchy texture and variety of flavors. You can use macadamia nuts, walnuts, pecans, or almonds. They contrast wonderfully with the soft and tender crumbs of the coffee cake.

Substitutions and Variations

Once you have the basics, you can modify this coffee cake in many ways.

Check out these fun ideas:

  • Skip the nuts for a more traditional coffee cake texture.
  • Drizzle the coffee cake with keto icing for a show-stopping finish.
  • Use the same icing but tuck it inside of the coffee cake instead. Pour half of the cake batter into the pan, drizzle the icing, followed by the remaining batter. Every bite is delicious and rich!
  • Make keto coffee cake muffins! Instead of a pan, bake this batter in bite-size mini muffins and frost with maple buttercream frosting.

A great thing about this recipe is that with slight modifications, you can tailor it to suit your diet best and fit your lifestyle. As written in the recipe card, this recipe is already naturally gluten-, grain-free, and sugar-free. It can easily be customized to make it dairy-free too! 

Check out these easy ways to modify the recipe and adjust for particular dietary needs:

  • Dairy-free – Swap coconut oil for butter and coconut cream for sour cream. 
  • Paleo diet – Swap out the low-carb sweetener and use sucanat or coconut sugar. Use coconut cream for sour cream. 
  • GAPS – Use raw honey instead of the sugar-free sweetener and use homemade sour cream that has been fermented for at least 24 hours. 


Follow along, and you can’t go wrong.

Step 1: Whisk

Preheat the oven to 350 degrees Fahrenheit. Grease an 8×8-inch glass baking dish and set it aside. You can also line it with parchment paper first, then grease it so it’s easier to remove the cake after baking.

Whisk the eggs in a small bowl. Add butter and cream until smooth. You can also use a hand mixer if it’s easier.

Step 2: Combine

In a separate bowl, combine all the dry ingredients together, including the spices. Whisk ground flax meal, coconut flour, almond flour, low-carb sweetener, cinnamon, baking powder, star anise seed, salt, and allspice powder. 

Step 3: Blend

Add the flour mixture to the wet ingredients and combine well. If desired, you can add the nuts now.

Transfer the coffee cake batter to a prepared pan. Add nuts to the top of the batter if you have not added them already. 

Step 4: Bake

Bake the coffee cake for 30 minutes or until it’s golden brown and a toothpick inserted into the center of the cake comes out clean. 

Remove from oven when it is done and allow to fully cool before cutting into it. If you cut into it before it’s fully cooled, it may be a bit gummy in the center. I prefer to cool it for at least 30 minutes before removing the cake from the baking pan and enjoying it.

Easy Keto Coffee Cake FAQ

What are the benefits of using flax seed meal in a keto coffee cake?

Working with a blend of flax seed meal, almond flour, and coconut flour allows the coffee cake to stay light and fluffy. It also crisps nicely around the edges and doesn’t dry up as it bakes. Almond flour coffee cake recipes tend to be too dense.

Can I substitute another flour for coconut flour or almond flour?

All three flours used in this recipe are not interchangeable because they have different properties and absorbency levels. It’s best to follow the recipe as written in the recipe card for best results.

How do I store keto coffee cake?

Store leftover coffee cake in an airtight container in the fridge for up to one week.

Can I freeze keto coffee cake?

You can freeze the coffee cake for longer storage. Ensure it is cooled completely and wrap tightly in plastic wrap or aluminum foil to prevent freezer burn. Then transfer to a freezer bag and freeze for up to 3 months. Thaw in the fridge overnight.

  1. can you please share a safer sugar substitute in place of powdered monkfruit or brown monkfruit. these contain erythritol and the new studies reveal dangers high enough to not ignore.

    • Hi, Dawn. I think there are many flaws in the design and study that the results are still unclear. Further study is warrented because an association was shown, but with insufficent causation. A simple example is saying every house fire involves houses that have sinks, so therefore sinks cause house fires. I suggest reading Peter Attia’s article: https://peterattiamd.com/more-hype-than-substance-erythritol-and-cardiovascular-risk/ It will help put your mind at ease. Additionally, you can also replace with allulose in a 1:1 ratio and not have to worry about it either way.

    I needed a gluten-free recipe to take to a mom’s group and came across this one. it was so delicious. I loved the anise flavor and the texture was perfect. super moist delicious with coffee or tea. everyone gobbled it up!

  3. 5 stars
    I love that you can freeze it! The coffee cake was so delicious but I couldn’t eat it all myself so I popped it in the freezer.

  4. 5 stars
    Mmmm, yes! So good, we made in muffin tins for convenience and more “Edges” — I’m an edge person, lol. Question — do you ground your own flax seed . . .I have come into a bag of seed, want to turn into into meal/flour … but don’t even know If I just put in the blender, or coffee grinder or how to do it.

    • Ah yes, those edges. Great idea. And yes, a coffee grinder works great for grinding flax seed because you don’t have to do so much as in a blender.

  5. 5 stars
    This coffee cake is so good! It’s moist, rich, and the macadamia topping added that perfect crunch. My mom didn’t even know it was sugar-free. Thanks for this recipe!
