Keto Sour Cream Coffee Cake

My keto coffee cake is a tender, buttery, moist, flavor-packed cake that features a generous cinnamon streusel crumb topping.

In my humble opinion, the best part of a well-made coffee cake is that crumble topping. That’s why my keto sour cream coffee cake is all about that streusel topping.

Clocking in at only 2.2 g net carbs, it’s the perfect sweet treat for anyone on a keto diet or who needs a gluten-free recipe.

My keto cinnamon coffee cake is made with simple-to-source ingredients like almond flour, sour cream, butter, eggs, spices, and a sugar alternative.

It’s an easy keto coffee cake that is the perfect accompaniment to your morning coffee. It is also a wonderful cake to share on Christmas morning since it’s a recipe the whole family will love, even if they are not on a low-carb diet.

Just because you’re on 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.

By the way, I have a complete list of keto cakes that any cake lover doing keto would enjoy exploring and a keto coffee cake recipes page where you can find more recipes like this one.

Low-Carb Sour Cream Coffee Cake

This almond flour coffee cake uses sour cream in the cake batter, which gives it a nice, tender crumb, and the slight tanginess of the sour cream compliments the overall flavor and balances the sweetness.

The combination of sour cream and melted butter ensures it is a moist keto coffee cake that tastes like a classic coffee cake that uses wheat flour and regular sugar.

Rest assured that this keto version will not spike your blood sugar.

How To Make A Keto Coffee Cake

To prepare the coffee cake, start by preheating the oven to 350 degrees and greasing a 10-inch spring-form cake pan with butter.

In a large mixing bowl, combine almond flour, sugar substitute, spices, baking powder, baking soda, and sea salt.

Then, in a separate bowl, stir together the cooled melted butter, sour cream, vanilla extract, and eggs until well combined.

Next, fold the wet ingredients into the dry ingredients and mix until well incorporated. Then, spread half of the batter into the springform pan.

To create the cinnamon sweetener layer that goes in the middle layer of the cake, combine granulated sweetener, cinnamon powder, and salt in a small bowl, then sprinkle this mixture over the batter in the prepared pan before adding the remaining batter.

I added this extra layer for more cinnamon flavor and because it is classically added.

For the streusel topping, combine sugar substitute, almond flour, nuts, salt, and cinnamon in a small bowl.

Then, add thinly sliced cold butter to the dry ingredients and cut it in until the mixture resembles coarse crumbs. Be sure to break apart any large pieces.

Sprinkle the crumb mixture over the cake batter and gently tap it into the batter.

Bake the cake for 35 to 50 minutes, until the crumbs are lightly browned and a toothpick inserted into the center comes out clean.

Allow the cake to cool for 20 minutes before slicing and serving. Any leftovers can be stored in the refrigerator or frozen in an airtight container.

Low-Carb Coffee Cake

Coffee cakes are usually enjoyed at breakfast with a cup of coffee, but who says that’s not a rule that can’t be broken?

As far as I am concerned, this gluten-free coffee cake would be a lovely addition after any meal and should be the star of any holiday table.

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

Thankfully, this is an easy, low-carb cake that you can make and serve any time of the day or year.

Is There Coffee In Coffee Cake?

Let me just clarify this point for you. You see, there is actually zero, nada, no 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 born.

Best Results When Using A Keto Streusel Topping

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

Steusel refers to a sweet topping usually made up of sugar, flour, cinnamon, and butter. It’s kind of a big deal in a coffee cake.

Tips For Making This Low-Carb Coffee Cake

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

• When making this cake, I recommend that all your cake batter ingredients be at room temperature. Doing so will allow your batter to blend easily and ensure the moistness of your coffee cake.
• The butter in the cake batter is melted and then cooled before the addition of the eggs. It’s key that the butter is allowed to fully cool to prevent the eggs from scrambling.
• The butter for the streusel topping needs to be cut into small pieces and very cold. The cold butter will ensure the right texture as you prepare the crumb topping. Using room-temperature butter can cause the topping to be gummy.
• 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.

Best Sugar Substitute For This Cake

When it comes to choosing which low-carb sweeteners to use, I have several for you to choose from.

My go-to choice is Lakanto granulated white 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. This is why it’s a great all-natural sugar substitute and has zero calories and a zero glycemic index.

They also have a golden monk fruit sweetener and a darker brown sugar substitute that would also work well in this recipe.

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.

Swerve also has a brown sugar alternative in case you want to go this route.

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 half the amount called for in this recipe since it’s much sweeter.

Truvia Sweet Complete, is a granulated, all-purpose stevia sweetener that measures cup for cup. You might want to try the stevia option.

They also have a brown calorie-free option that measures cup for cup, which you might want to use. If using any of the Truvia Complete sweeteners, you would use the exact amount called for in the recipe.

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

How To Store This Cake

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

Your keto-friendly 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 add a layer of heavy-duty aluminum foil.

Your low-carb coffee cake can be frozen for up to 1 month for the best flavor, but it can be frozen for longer.

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.
