Keto Sour Cream Cinnamon 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 while avoiding the carbs in regular coffee cakes. 

And if you are a fan of blueberries, I have a keto blueberry buckle (coffee cake) you should also give a try!

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

Keto Coffee Cake

This keto-friendly coffee cake uses almond flour which ensures the cake is not only low in carbs but gluten-free. Therefore this is an almond flour coffee cake that is not only delicious but a great option for those avoiding gluten.

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.

If you’re a fan of sour cream in cakes, you should also try my keto sour cream pound cake for another delicious option.

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 sour cream 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. 

Best Sugar Substitute For Keto Coffee Cake

When it comes to choosing which sugar substitute to use for this keto coffee cake, I have several for you to choose from. 

My go-to choice is Lakanto Monk Fruit because the texture is spot on since there is barely any aftertaste. It is a monk fruit and erythritol blend.

Lakanto Monk Fruit gets its sweetness from antioxidants called mogrosides, instead of fructose or sucrose. It’s why it’s a great all-natural sugar substitute and has zero calories and zero glycemic index.

I’m also partial to  Swerve an erythritol blend. Unlike other natural sweeteners like stevia, it has no bitter aftertaste and measures just like sugar.

Swerve is the name brand of Erythritol it’s unlike other sugar alcohols that have a 0 % impact on blood sugar.

You could also use the stevia and erythritol-based brand Pyure for most of my baked goods. 

But if using Pyure you will want to use 1/2 the amount called for in this recipe since it’s much sweeter.

Lastly, if you can easily find a more natural sugar substitute you can also use Splenda with great success. 

You will want to use the Splenda that has a bulking agent. It’s the one that comes in larger bags. I don’t recommend Splenda Bake because it’s actually half sugar half sucralose product and will be too high in carbs to be considered keto-friendly.

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. 

You see I told you I really loved the coffee cake. I really hope you see that it’s my desire to give you easy low carb, keto recipes that make this lifestyle easier.
