Keto Butter Cake

This keto butter cake is made with simple ingredients and produces a fluffy, rich butter cake that also features a buttery glaze.

The butter glaze adds additional butter flavor and moisture. It’s what makes this low-carb butter cake recipe perfect for any occasion. 

I’m a believer that butter makes everything better, and this recipe for keto butter cake is further proof of this.

When you cream butter until the mixture is pale and fluffy, it gives the cake the perfect texture. 

This low-carb butter cake recipe uses butter in the batter and the icing that soaks into the baked cake, making it very moist. 

Making this a keto bundt butter cake makes it not only a delicious treat but a stellar-looking dessert that will have even your non-keto family and friends raving about it.

Keto Butter Cake

If you’re a fan of moist cakes with a tender crumb, then this recipe has your name on it. The best part is that it uses easy-to-source ingredients common in keto baking.

I like using a combination of almond flour and coconut flour in this recipe. It’s something I did with my keto brown butter Kentucky cake recipe. It worked beautifully in that recipe, and so I knew it would work well in this one too.

Is Butter Cake And Pound Cake The Same?

If you are wondering if butter cakes are one and the same, they are not. Butter cakes are also called creamed cakes and have a lighter texture and typically more volume.

In a butter cake, the butter is beaten with a sweetener for a minimum of five minutes; it turns a pale yellow color and becomes light and airy. This produces a rich, moist, fluffy keto butter cake.

What’s The Best Butter To Use In Butter Cake?

When making a butter cake, you should only use unsalted butter. Salted butter can vary greatly from brand to brand, and you won’t get consistent results. 

It’s best if the salt does not have salt and you add it to the cake recipe instead.

It is also important to use only room-temperature butter that has been allowed to soften. You want the butter soft enough that when you press it with your finger, it leaves behind a dent. 

Tools You’ll Need To Make A Keto Butter Cake

The only tools you’ll need are an electric mixer or a stand-up mixer and a bundt pan, 

Let me also mention that the type of bundt pan you use is important. Not all are created equal, and after a while, bundt pans don’t release the cakes well, so investing in a good one is worth the tiny investment.

I use CasaWare’s brand because it has a granite ceramic that makes for easy release baking. 

How To Make A Keto Butter Cake

You’ll start by preheating the oven to 350 degrees. Then grease well with solid butter in a 12-cup capacity bundt pan.

In a large bowl, measure and sift the almond flour.

Then, measure the coconut flour and add it to the large bowl with the sifted almond flour. Next, add the baking powder and salt. 

Using an electric beater beat the softened butter, and sugar substitute until light fluffy for a minimum of 3 minutes. The mixture should turn a pale yellow and be light and fluffy. 

Add the vanilla extract. Next, you’ll add the eggs one at a time be sure to combine well after each addition.

Then, slowly add all the dry ingredients, one tablespoon at a time, while continuing to use the mixer. Lastly, fold in the heavy cream. 

Once the batter is ready, spread it evenly into the prepared bundt pan. You’ll bake the cake on the center rack for 45-50 minutes until an inserted toothpick comes out clean.

Allow the cake to cool in the pan for 10 minutes before inverting it to a baking rack.

While the cake cools completely on the baking rack, proceed to make the butter icing. To make the icing, simply melt the butter in a small saucepan on the stovetop over medium-high heat. 

Then add the confectioner’s sugar substitute along with the salt and heavy cream and allow the mixture to come together and be heated.

Drizzle the entire cake with the icing allowing it to seep into the cake.

Once the icing has been added, allow the cake to absorb the icing and set it for another ten minutes before slicing and serving.

Best Sugar-Free Sweetener Options

To make a sugar-free butter cake, you’ll need to replace regular sugar with a sweetener that doesn’t raise your blood sugar.

My number one choice is Lakanto a monk fruit sweetener because the texture and flavor are what I have found to be the closest to real sugar, and because the flavor fools your taste buds like nothing else I’ve found in the market. 

Having said that, I’m also partial to the brand Swerve which is an erythritol blend. Similar to Lakanto, it uses sugar alcohols and has 0% impact on blood sugar.

Personally, I don’t like using stevia because I am sensitive to the aftertaste. But if that’s not the case for you, you could certainly use the stevia and erythritol-based brand Pyure for this cookie recipe.

However, if you go this route, you will want to use 1/2 the amount called for in this recipe since it’s much sweeter.

As far as confectioners’ sugar substitutes you’ll need for the butter icing, both Lakanto and Swerve have great products.

I’ve included instructions on how to make a less sweet cake for those of you looking for that option.
