Chocolate Peanut Butter Bundt Cake
This recipe turned out to be the perfect combination of peanut butter and chocolate. The hardest part about baking in the air fryer is finding a pan that will fit inside your air fryer.
I recommend that you have at least a 6-quart air fryer to make this swirl bundt cake. If you are having a hard time finding a bundt pan to fit in your air fryer, look for an Instant Pot bundt pan. That one is 7 inches so make sure it will fit inside your air fryer before you buy it!
These bundt pans are half the size and work beautifully to make individual desserts. Just adjust cooking time accordingly by half.

This recipe may look complicated, but when you break it down into individual steps, it’s really not that difficult. Take it slowly and go step by step, and you’ll find that this recipe is really quite simple.
Step 1: Prep the Bundt Pan
To prepare the bundt pan, stir the melted butter and cocoa powder together to form a paste. Using a pastry brush, coat the bundt pan interior with the paste and then sprinkle with cocoa powder.
Step 2: Divide an Egg
Take an egg and crack it into a small bowl. Whisk it and set it aside. You’ll use half of the egg for the cake batter and half of it for the peanut butter cheesecake swirl.
Step 3: Prepare the Wet Ingredients
Combine cocoa powder and chopped chocolate. Add boiling water and whisk until melted and smooth, then let cool for 10 minutes. Add sour cream and vanilla extract and whisk to combine.
Step 4: Prepare the Dry Ingredients
In a separate bowl, combine flour, salt, baking soda, and peanut butter morsels.
Step 5: Make the Batter
Slowly incorporate the wet and dry ingredients together, combining about one-quarter of each at a time until fully combined.
Step 6: Make the Peanut Butter Cheesecake
In a medium mixing bowl, combine softened cream cheese, peanut butter, heavy whipping cream, the remaining egg, vanilla extract, and confectioners sugar, whisking until smooth.
Step 7: Add the Batters to the Pan
Pour one-third of the cake batter into the bundt pan. Then, ad half of the peanut butter cheesecake to the center of the pan so that the cake batter is visible on each side of the cheesecake.
Repeat this process, keeping the peanut butter cheesecake in the center of the pan with the cake batter exposed on all sides, finishing by topping with the remaining cake batter.
Using the handle of a fork, a chopstick, or a butter knife, swirl the cheesecake and cake batter together gently to create a marble effect.
Step 8: Air Fry the Cake
Air fry the cake until a toothpick inserted into the center of the cake comes out clean. Remove the cake from the air fryer and let cool.
Step 9: Prepare the Peanut Butter Cream Drizzle
Mix all the drizzle ingredients in a small bowl.
Step 10: Add the Peanut Butter Cream Drizzle
Carefully flip the bundt pan over onto a plate and gently pull it away from the cake. Then, drizzle the cake with the glaze.
Hint: To make it easier to remove the cake from the bundt pan, gently tap the pan all over after turning it upside down onto the plate.
