FAQs
What is a dump cake?
A dump cake is a simple dessert where you “dump” all ingredients into a bowl or baking dish and bake without complicated mixing or layering. This version uses pudding and milk mixed with cake mix and peanut butter cups, resulting in a moist, fudgy cake.
Can I use a different flavour of cake mix?
Yes, you can experiment with other cake mix flavors depending on your preference. Chocolate works wonderfully here, but vanilla or peanut butter cake mixes could also complement the peanut butter cups nicely.

Ingredients
Dry Ingredients
- 1 box (15.25 oz) chocolate cake mix
- 1 small box (3.4 oz) instant chocolate pudding mix
Wet Ingredients
- 1 1/4 cups whole milk (or any milk on hand)
Add-ins
- 8 oz mini peanut butter cups, roughly chopped (such as Reese’s)
Instructions
- Mix The Pudding And Milk: In a large bowl, whisk together the instant chocolate pudding mix and milk until smooth and well combined, creating a moist base for the cake batter.
- Add The Cake Mix: Stir in the chocolate cake mix into the pudding mixture until fully blended. The resulting batter will be thick, which is expected for this dump cake.
- Fold In The Peanut Butter Cups: Roughly chop the mini peanut butter cups and gently fold them into the thick batter to distribute the peanut butter pockets throughout the cake.
- Bake: Pour the batter into a greased 13 x 9 inch baking dish and spread evenly. Bake in a preheated oven at 180°C (350°F) for about 25 minutes or until a skewer inserted into the center comes out clean. Allow the cake to cool slightly before serving. It is especially delicious when served warm, optionally topped with vanilla ice cream.
