Chocolate Peanut Butter Dump Cake


Have you ever made a dump cake? They’re so easy. Usually they are fruit based. Dump in a can of pineapples, dump in the dry cake mix and melted butter on top. This one’s a bit more kid friendly with the chocolate peanut butter combo. It was my turn to bake for my daughter’s youth group last Sunday at church, so I wanted to make something the “tweens” would like. They definitely loved this. We offered cupcakes and brownies as well, but all the kids wanted this! Ooey, gooey, chocolate peanut buttery goodness with Reese’s peanut cups baked right in and also sprinkled on top a pillow of creamy, dreamy Cool Whip. And don’t forget the chocolate syrup drizzled on top.


Chocolate Peanut Butter Dump cake is a combination of chocolate pudding, cake mix, peanut butter cheesecake and peanut butter cups. It’s moist and delicious, topped with whipped topping, more peanut butter cups and drizzled with chocolate syrup. Yum!


Let’s discuss the dumping part. First you stir together a chocolate cake mix, chocolate pudding and milk. It will be thick. Fold in a bag of Reeses mini chocolate peanut butter cups. Then it’s time to dump…


Dump it in a greased 13″x9″ pan. Spread to cover pan.


Mix up some cream cheese, powdered sugar, peanut butter and heavy cream. Pour that over the cake batter.


Now take another chocolate cake mix and you guessed it, dump it! Pour 1 stick of melted butter on top. That’s it. You’re ready to bake!


Bake at 350°F. for 35 minutes. Let it cool. Top with whipped topping such as Cool Whip and chopped Reeses peanut butter cups. Drizzle with chocolate syrup.


Watch it disappear.

    These are tremendous. And so easy.

  3. The instructions forgot to include the folding in of the first batch of Reece’s minis. They are only listed in the ingredients.

  4. Oh My Goodness! You’re right! It’s been corrected. Thanks, Cynthia!

    I am not sure if I am supposed to make first cake batter as instructed on package and add in milk and pudding? Or just milk and pudding? No eggs? Oil?

  6. Hi Kim, Just add the milk and pudding to the cake mix. You do NOT make it according to package instructions. Hope that helps. Enjoy! 🙂

    I am so excited to bring these to my Bible Fellowship class tonight. My only question is how do we know when the cake is done? Seems like the typical toothpick method will not work with this one. I just took it out of the oven and it seems to be a bit more like jiggly jello. Is this how it is suppose to be?

  8. Ash says:

    Is it dry cake mix, dry pudding mix, and milk? For the first batch or are you making the pudding?

  9. Maureen says:

    I am not a big fan of chocolate cake. Don you think I could substitute yellow cake. I do love chocolate just not cake.

  10. Alissa says:

    Is it to set up like a cake or jello like

  11. Alicia says:

    Is it supposed to set like a normal cake or is it supposed to be more loose ? I cant tell if it’s done
