Because peanut butter and chocolate go together like Ross and Rachel, like Thelma and Louise, and like Harry and Sally (and yes, I’ll have what she’s having if she’s having peanut butter and chocolate). This cake is soooo good. I make it all the time and everyone loves it. It’s my go-to recipe if I’m trying to bribe someone into being my friend. It usually works unless they’re allergic to peanuts (Hi, Meaghan, sorry about the hospital trip).

Prep pan
Cake
- 1 box of chocolate cake mix (I used Betty Crocker Super Moist Triple Chocolate Fudge)
- 1 3.9 ounce box of instant chocolate pudding mix (I used Jello)
- 1 16 ounce container of sour cream (it seems like a lot, I know, but it means you can use less vegetable oil, which I prefer)
- 1/3 cup vegetable oil
- 1 tsp vanilla extract
- 3 eggs – room temperature
- 1/2 cup warm water
- 1 10 oz bag of peanut butter chips, divided (reserve 2/3 of a cup for the ganache, and add the rest to the cake batter).
- 1 10oz bag of semi-Sweet chocolate chips (reserve 2/3 of a cup for the ganache, and add the rest to the cake batter)
Peanut Butter Filling
- 1 cup creamy peanut butter
- 1/3 cup powdered sugar
- 4 tablespoons butter melted
- 1 teaspoon vanilla extract
- Big pinch of salt
Chocolate Ganache
- 2/3 cup semi-sweet chocolate chips
- 1/3 cup heavy cream
Peanut Butter Ganache
- 2/3 cup peanut butter chips
- 1/3 cup heavy cream
Cake Instructions
Step 1
Move your oven rack to a lower position. I’m not sure why I do this, but it always seems to bake more evenly when I do. Maybe it’s science, maybe it’s superstition. Either way, why mess with it? Preheat oven to 350° Grease and flour your pan, or use Bundt Gunk and set aside
Step 2
Combine all of the cake ingredients, except for the peanut butter and chocolate chips, and mix until not quite combined. You still want to see a few flour streaks. Mix in the chips until everything is just combined (overmixing the batter leads to a dry cake, and you need a stuffed bundt to stay as moist as possible).
Step 3
In a separate bowl, combine peanut butter, butter, powdered sugar, vanilla, and salt and mix well with a hand mixer.
Step 4
Spoon half of cake batter into a bundt cake. Go slowly doing this. You want the batter to naturally fill all the grooves at the bottom of the pan (which will end up being your top). Going slowly allows the batter to settle and prevents air pockets. Tap the pan on the counter to remove any air bubbles you might have.
Step 5
Spoon the peanut butter filling on top of the cake batter. I spoon a ring in the middle of the bundt to keep all of the filling encased by the cake.
Step 6
Top with remaining cake batter. If your batter doesn’t look evenly distributed, you can use a spatula to flatten it out, but try not to marble the cake, or it will earn you less friends. When your bundt bakes, the center will naturally rise more, so I try to push my batter with the spatula to the outer edges so they’re a bit higher. This helps the bundt to lie flat when you plop it out.
Step 7
Bake for 50-55 minutes. You’re going to have to use your best judgement/gut feeling when it’s done. A toothpick will never come out cleanly from a stuffed bundt. Let your bundt sit for 30 minutes before flipping it. Let it fully cool before adding the two ganaches.
For glaze(s):
In a large microwave safe bowl combine the chocolate chips and heavy cream. Microwave for 30 seconds, remove from microwave and stir well. Return to microwave for another 15 seconds. Remove from microwave and whisk together until smooth (stirring will help melt chocolate). If needed, heat for an additional 15 seconds, then whisk until smooth. Spoon or pour over cake. Let it set for about ten minutes before repeating the above steps with the peanut butter chips.
