This Peanut Butter Dong Dong Cake is a variation of my favorite childhood treat! (Based on my famous Ding Dong Cake!) Rich chocolate cake, creamy peanut butter filling, and a heavenly chocolate ganache on the outside. If you love chocolate and peanut butter, this is the cake for you!

Peanut Butter Ding Dong Cake

What is a Ding Dong? It is a treat that we were often given as kids.  Basically a chocolate whoopie pie with a glorious cream filling. I recently saw a Peanut Butter Ding Dong in the grocery store and new I needed to make it into a cake!

This cake is one of those cakes where the ingredients work together in perfect harmony to create a cake that you will never forget. I encourage you to make your own buttermilk! You can use it for this recipe, as well as many others!

Chocolate Cake with Peanut Butter Filling

Peanut Butter Filling

Some of you experienced bakers recognized this filling immediately! It’s a peanut butter mousse and can be served on its own. This frosting has a few extra steps compared to a traditional American buttercream, but the result is well worth it. Subtle, peanut buttery, and creamy, it is the PERFECT filling for this beyond rich cake.

I do NOT recommend using chunky peanut butter or all-natural peanut butter in this recipe. The chunky just doesn’t work in a smooth creamy filling and the all-natural peanut butter is a bit too oily for this recipe. But if you want to get some texture feel free to add chopped peanuts to the top!

Can I Prepare this Peanut Butter Ding Dong Cake in a Different Pan?

You can make it in a 9×13 pan, but in that case, I would assemble a bit differently. I would prepare the cake and let it cool. Prepare the peanut butter filling (mousse) and spread it over the cake, then chill it until firm. Then prepare the ganache, cool, and pour over the chilled cake.

Can you Substitute Anything for Coffee?

Yes, of course. You can use hot water in place of coffee. But I highly recommend trying it WITH the coffee! You don’t actually taste it, as coffee just enhances the chocolate and doesn’t flavor the cake.

This is a fantastic Peanut Butter Ding Dong Cake and a lovely way to celebrate with friends and family!

The chocolate cake in this recipe is my Perfect Chocolate Cake.

This Peanut Butter Dong Dong Cake is a variation of my favorite childhood treat! 


Chocolate Cake

  • cups (210g) all-purpose flour
  • 2 cups (400g) granulated sugar
  • ¾ cup (90g) good unsweetened cocoa powder
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon kosher salt
  • 1 cup (240g) buttermilk room temperature
  • ½ cup (112g) vegetable oil
  • 2 extra-large eggs, room temperature
  • 2 teaspoons McCormick pure vanilla extract
  • 1 cup (237g) freshly brewed hot coffee

Peanut Butter Filling

  • ½ cup (119g) heavy whipping cream
  • 4 ounces cream cheese
  • ½ cup (129g) creamy peanut butter
  • 1 teaspoon vanilla extract
  • ½ cup (60g) confectioners' sugar
  • 1 tablespoon milk, (I prefer whole)


  • 16 ounces semi-sweet chocolate chopped fine (can use milk chocolate)
  • 16 ounces (2 cups) heavy cream room temperature


Chocolate Cake

  • Sift the flour, sugar, cocoa, baking soda, baking powder, and salt into the bowl and mix until combined.
  • In another bowl, combine the buttermilk, oil, eggs, and vanilla.
  • In the bowl of a stand mixer on low speed, slowly add the wet ingredients to the dry. With mixer still on low, add the coffee and stir just to combine, scraping the bottom of the bowl with a rubber spatula. 
  • Pour the batter into two 8-inch x 3-inch round prepared pans and bake for 30-40 minutes at 350°F, until a cake tester or toothpick comes out mostly clean (not wet).
  • Cool in the pans for 30 minutes, then turn them out onto a cooling rack and cool completely.

Peanut Butter Filling

  • Pour the cream into a mixing bowl and beat with an electric mixer until peaks form about 2-3 minutes. Scoop the whipped cream into a small bowl and place in refrigerator.
  • Combine the cream cheese, peanut butter, and vanilla in a mixing bowl and beat until smooth, 1-2 minutes.
  • Add confectioners sugar and beat again for another minute.
  • Add the milk and beat until smooth, about 20-30 seconds.
  • Fold the chilled whipped cream into the peanut butter mixture and stir until combined.


  • Heat the heavy cream in a quart-sized, microwavable container and microwave for 3 to 4 minutes on high, or until it just begins to simmer. Be careful not to allow the cream to boil over. Pour the cream over the chopped chocolate and let stand for at least 2 minutes so that it can thicken.
    (Ganache should be cool when pouring over cake)
  • When ready to pour over chilled cake, whisk the ganache until smooth and then pour. You may have some ganache left over.


When ready to assemble cake, spread peanut butter filling over one layer of chocolate cake, then set the other layer on top.
Chill. Cover with prepared ganache.
Chill cake until ready to serve.

  1. Amazing cake !Mindblowing!!!
    I only reduced the sugar quantity to 1.5 cup .I baked it for my sons birthday and everybody loved it !

  2. My son would love this for his birthday cake! I’m wondering if I can assemble it the night before serving and Refrigerate overnight?

    1. Hi, Amber! I work with iambaker and am happy to help with questions. Yes, you can refrigerate it. Have a wonderful day!

  3. Oh.My.Goodness!!! I made this for a small gathering of friends and it was the hit of the night. The ganache was a bit thin, but I don’t think I allowed it to cool enough. The cake was the perfect texture and the mousse was so light. It’s certainly a keeper recipe that will be done again and again.

  4. Thank you for the recipe
    I’m just want to make sure in your recipe is do not put a 1 tsp of baking powder, am I correct?
    Looking forward to make this cake for my daughter birthday.
    Thank you 😊

  5. I made this for my son’s birthday last year and he loved it so much he requested it for his birthday this year this is an awesome cake
