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 believe that butter makes everything better, and this keto-friendly butter cake recipe 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.
I have many keto cakes that you should also check out for delicious options.
Easy Keto Butter Cake
If you’re a fan of a moist cake with a tender crumb, this recipe has your name on it. The best part is that it uses easy-to-source ingredients that are 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.
Clocking in at only 3.6 net carbs per cake portion, it’s a dense cake you can enjoy while on a keto diet. It’s a great option when you are looking to silence your sweet cravings.
Since no wheat flour is used in this entire cake, it’s also a gluten-free cake. Winning!

Is Butter Cake And Pound Cake The Same Thing?
If you are wondering if butter cakes are the same as pound cakes, they are not. Butter cakes, also called creamed cakes, 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, buttery keto cake.
Although this is not a keto pound cake, it’s a ketogenic diet recipe that rivals a traditional butter cake made with regular flour.
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 significantly 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 essential to use only room-temperature butter that has been allowed to soften. You want the butter to be 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 main tools you’ll need to make this keto cake recipe are a large mixing bowl, 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 it easy to release from the pan.
How To Make A Keto Butter Cake
You’ll start by preheating the oven to 350 degrees f. Then, grease well with solid butter in a 12-cup capacity bundt pan.
In a large bowl, measure and sift the almond flour and set it aside.

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 and fluffy for a minimum of five minutes. The mixture should turn a pale yellow and be light and fluffy for the best results.
Add the vanilla extract. Next, add the eggs one at a time, being sure to combine well after each addition.
Then, slowly add all the dry ingredients, one tablespoon at a time, to the wet ingredients while using 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 golden brown and 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, melt the butter in a small saucepan on the stovetop over medium-high heat.
Then, add the confectioner’s sugar substitute, salt, and heavy cream, and allow the mixture to come together and be heated.
Drizzle the cake with the icing, allowing it to seep into the cake for added buttery flavor.
Once the icing has been added, allow the cake to absorb the icing and set it for another ten minutes before slicing and serving.
Store leftovers in an airtight container in the refrigerator for up to five days or freeze for up to three weeks.
Best Sugar-Free Sweetener Options
To make a sugar-free butter cake, you’ll need to replace regular sugar with low carb sweeteners that doesn’t raise your blood sugar.
My number one choice is Lakanto, a monk fruit sweetener. The texture and flavor are what I have found to be the closest to real sugar, and the flavor fools your taste buds like nothing else I’ve found on 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.
I don’t particularly 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 half 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.
