Keto Peanut Butter Bundt Cake

This keto peanut butter cake is a peanut butter lover’s dream! It’s a moist, dense, and rich cake that ensures peanut butter is the star.

If you are a peanut butter flavor fan on a keto diet, this cake is calling your name.

As a major fan of peanut butter myself, I already have a recipe for some keto peanut butter cake bars that have a soft, slightly chewy texture.

But the recipe I’m sharing today is a cake, true and true.

This keto peanut butter bundt cake has a pound cake-like texture and features decadent peanut butter icing for one delicious peanut butter cake!

It’s a great choice to curb your sweet cravings without a blood sugar spike. Even if you are not on a low-carb diet, you’ll love this moist cake.

Keto Peanut Butter Bundt Cake

This delicious cake could have easily been baked in two 9-inch cake pans and then used as a layer cake. It would also make a stunning keto Texas sheet cake when baked in a 9×13-inch pan.

But I wanted the stunning presentation and ease that a bundt cake brings to the table.

I love how the cake bakes nicely in 50 minutes and is released from the pan effortlessly. Baking the cake until it has a nice golden crust makes a great foil for the velvety, smooth peanut butter icing.

In order to make this decadent, low-carb peanut butter cake fool-proof, I am sharing the list of ingredients and some important tips.

Note that the printable recipe card is at the bottom of the page, but I hope you stick around for my tips.

• Almond flour, finely milled
• Coconut flour
• All-natural peanut butter, smooth
• Chopped salted peanuts, for sprinkling on top
• Unsalted butter, room temperature
• Cream cheese, full-fat
• Heavy cream
• Sugar Substitute, granulated
• Confectioner’s sugar substitute, for sugar-free peanut butter frosting
• Eggs, room temperature
• Vanilla extract
• Baking powder
• Salt

Tools

The essential tools you’ll need are an electric mixer, a couple of bowls, and a bundt pan.

I used a 9.5-inch 12-cup bundt pan to make this recipe because it allows the cake to bake evenly on all sides and produces a lovely golden crust.

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 properly, so investing in a good one is worth it. I use CasaWare’s brand because it has granite ceramic that makes for easy-release baking.

How To Make A Keto Peanut Butter Cake

To prepare this low-carb peanut butter cake, preheat the oven to 350 degrees and thoroughly grease a 9.5-inch 12-cup bundt pan with butter.

In a large bowl, sift the almond flour, and then add the coconut flour, baking powder, and salt. In another large bowl, use an electric beater to mix the softened butter, cream cheese, and sugar substitute until well combined.

Then, add the peanut butter, vanilla extract, and eggs one at a time, mixing well after each addition. Slowly incorporate the dry ingredients into the wet mixture, followed by folding in the heavy cream.

Transfer the cake batter to the greased bundt pan and bake on the center rack of the oven for 50–55 minutes.

Once baked, allow the cake to cool in the pan for 10 minutes before inverting it onto a cake plate.

While the cake cools, prepare the icing by combining cream cheese, butter, peanut butter, confectioner’s sugar substitute, and vanilla extract with an electric mixer. Gradually whisk in the heavy cream to achieve a thick but pourable consistency.

For the peanut butter drizzle, combine peanut butter and coconut oil in a small bowl and microwave for 20 seconds before drizzling it over the iced cake.

Finally, sprinkle chopped peanuts on top and store any leftovers in the refrigerator for up to 5 days or freeze for up to 3 weeks.

The More Natural Sugar Substitute Options

When it comes to choosing which sugar substitute to use for this peanut butter keto cake, I have some options for you. My two favorite granulated sugar substitutes for this recipe are Lakanto Monk Fruit and Swerve.

You could also use the stevia and erythritol-based brand Pyure. But if using Pyure, you will want to use half the amount called for in this recipe since it’s a much sweeter option.

Lastly, if you can’t easily find a more natural sugar substitute, you can also use Splenda.

However, when it comes to keto peanut butter icing for this bundt cake, you will have to use a confectioner’s sugar substitute. Both Lakanto and Swerve have great ones.
