Keto Sour Cream Cinnamon Coffee Cake

keto sour cream coffee cake

It’s a tender, buttery, moist, flavor-packed keto coffee cake. This cake features a generous cinnamon streusel topping and it’s easy to make. What more can you ask of a keto cake?

My keto sour cream cinnamon coffee cake is all about the streusel topping. Because in my humble opinion, a well-constructed coffee cake should feature a lot of rich streusel crumb topping.

Not enough cinnamon crumb topping and this girl feels seriously deprived.  Who’s with me on this?

I mean isn’t the best part of coffee cake the topping? 

Just because you’re doing a ketogenic diet doesn’t mean you can’t enjoy a delicious coffee cake. I am confident that my keto cinnamon coffee cake will keep you safely in ketosis and while avoiding the carbs in regular coffee cake. 

By the way, I have a complete list of Keto Cakes that any cake lover doing keto would enjoy exploring.

Keto Sour Cream Coffee Cake

You may have tried my first low carb coffee cake recipe and therefore be wondering why I felt the need to create another.  Especially since I raved about my first one so much.

Well, that’s because this almond flour sour cream coffee cake may be similar to my low carb one, but this one is sour cream-based and makes it just a little more traditional. 

The biggest difference in using sour cream in a coffee cake is that it really gives it a nice tender crumb and the slight tanginess of the sour cream really compliments the overall flavor of this type of cake. 

Keto Sour Cream Coffee Cake

The sour cream addition makes for a really moist melt in your mouth low carb coffee cake recipe. And that my friend is a win in this coffee cake lover’s heart.

Plus, most coffee cakes use sour cream to give it added richness.  And maybe, just maybe I wanted an excuse to come up with another coffee cake recipe.

Can you fault me for this? One of the perks of recipe creation is that I get to test them for you. It’s a tough job but someone needs to do it.

Low Carb Coffee Cake

Coffee cakes are usually enjoyed at breakfast, but who says that’s not a rule that can’t be broken? As far as I am concerned, this keto coffee cake would be a lovely addition after any meal and should be the star of any holiday table. 

A keto streusel coffee cake should go hand in hand with a nice big mug of coffee. Not that other cakes can’t too but the coffee cake was named for this very reason.

Thankfully this is an easy keto coffee cake and one you can make and serve any time of day or year.

Is There Coffee In Coffee Cake?

Let me just clarify this point for you. You see there is actually zero, nada, coffee in coffee cake. It’s simply referring to the fact that it goes so well with coffee. 

The way I see it there was some lovely grandma in Germany who wanted to create a cake for her family that would accompany their coffee ritual and tada! The coffee cake recipe was birthed. 

Keto Streusel Topping

Can we talk a little bit more about the keto crumb topping of this coffee cake? You see this cinnamon keto cake star feature, is the buttery, crisp streusel top layer. And it’s why I add a lot of streusel to this cake. 

The first coffee cakes are thought to have their origins in Germany, hence my little grandma’s comment earlier. And the word streusel just means to mix quickly together. It comes from the word streuen or to strew. 

And it refers to a sweet topping that is usually made up of sugar, flour, cinnamon, and butter. It’s kinda a big deal in a coffee cake. 

But I completely understand if that’s not you. In which case feel free to make half of what the recipe calls for. I won’t be offended I promise if you choose to add less topping to this coffee cake.

How To Make A Keto Sour Cream Coffee Cake

I have a few tips you will want to keep in mind when making this keto sour cream coffee cake. After all, you want your coffee cake to be amazing enough for everyone in your family to enjoy including those who are not doing keto.

  • When making this keto coffee cake I recommend that all your ingredients be at room temperature. Doing so will allow your batter to blend easily and ensure that your coffee cake is moist.
  • As I said, the streusel topping is quite generous so keep this in mind. Some people may rather have less streusel on their coffee cake and if that’s you, then half the streusel topping recipe is enough. As a bonus, this will shave off 2 additional carbs. 
  • If you do make the recipe as called for, I suggest you gently tap the streusel topping into the batter before baking so that your coffee cake doesn’t fall apart.
  • I made my coffee cake in a round 10-inch springform pan. However, you can also bake it in a 10X10 inch square pan too.
  • For more flavor options add 1/2 cup of chopped walnuts, pecans, or walnuts. This will give the coffee cake a little extra crunch.
  • Top your coffee cake with 2 tablespoons of your favorite sugar-substitute confectioner’s sugar just for fun. This is totally optional. 

How To Store Keto Coffee Cake

Because of the many fresh ingredients in keto baked goods you generally always want to refrigerate any leftovers. 

Your keto coffee cake will stay fresh in your refrigerator for up to one week in an airtight container. It can also be frozen easily.

Yes, coffee cake can be frozen but in the case of this keto sour cream coffee cake, you want to make sure you allow your cake to fully cool and then tightly wrap it with plastic wrap and then a layer of heavy-duty aluminum foil. 

Your low carb coffee cake can be frozen up to 1 month for the best flavor but can be frozen up to 3 months with no safety issue. 

Then simply allow your keto coffee cake to thaw in the refrigerator before serving. Alternatively, you can freeze your coffee cake already sliced for added convenience.

  1. I never leave reviews, but this is the best coffee cake i’ve ever had keto or not. Thank you so much!

    • Wonderful Jessica. So glad to hear you enjoyed the recipe. Thanks for stopping by to comment and rate the recipe especially since it’s not something you are used to doing. Your lovely comment really encouraged me.

  2. This is fantastic!!! So delicious. I have really missed a carby coffee cake in the eight months I’ve been keto and THIS masterpiece is so amazing! BETTER than what I remember. I also adore your banana walnut bread – literally tastes just like the real thing – and your cream cheese chocolate chip cookie bars taste exactlyyy like chocolate chip cookies that I remember when I warm them up right before eating. Your recipes are just wonderful, thank you so much for sharing them! Also, I appreciate your theology background and tying in faith with our health

    • Hi Abby, so glad to hear that you are enjoying our recipes and appreciate the fact that I feel compelled to share my faith while doing so. If you are not part of private facebook I encourage to join us where other believers have come together to support one another.

  3. I am so happy to have found this recipe! My mother-in-law made a very similar recipe that is definitely not keto. I have to tell you how she made it, and now i have adapted this to make it her way! We use a chocolate topping!!! I put half of the batter in the pan, then half of the topping, then repeat with the other half of the batter and topping. I used 3T cocoa powder and 3T swerve for my topping. We actually fight over the middle pieces and hope that it sinks in the middle. Those are the best pieces!! Thank you so much for this recipe, it is such a wonderful treat. I am getting ready to make it to take camping with us! I will probably double it and put it in a 9 x 13 🙂
