Keto Peanut Butter Bundt Cake


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



As a major fan of peanut butter, I already have a recipe for some keto peanut butter cake bars which has a soft, slightly chewy texture. But the recipe I’m sharing today is a cake true and true.

The keto peanut butter cake has a pound cake-like texture and features decadent peanut butter icing. It’s a keto peanut butter pound cake recipe that is sure to stop a peanut butter craving in its track.

This delicious cake could have easily been baked in two 9 inch cake pans and then used in 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 that a bundt cake brings to the table and its ease.  

I love how the cake bakes nicely in 50 minutes and 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.

This keto peanut butter cake comes together quickly and has a satisfying dose of peanut butter not to mention that it’s also beautiful. All these qualities make it a perfect keto dessert to share with peanut-butter-loving guests, especially since even non-keto folks will swoon for this cake. 

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. 



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

The 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 or Swerve.

You could also use the stevia and erythritol-based brand Pyure. But if using Pyure you will want to use 1/2 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. 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 

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.

Hi Charlene, I'm sorry to hear you are allergic to coconut flour. I have not tested this cake substituting the coconut flour so I cannot give you those measurements.
