You are going to fall head over heels for this Peanut Butter Cup Dump Cake the moment you read the ingredient list. It comes together in under 35 minutes using just four simple ingredients, so there is no fancy technique, no creaming butter, no fussing with layers.
The chocolate pudding mix is the secret weapon here: it keeps the cake impossibly moist and fudgy, almost like a brownie, while the chopped mini peanut butter cups melt into every bite. It feeds a crowd straight from the pan, making it perfect for potlucks, family gatherings, or just a Tuesday night when you need something seriously chocolatey. This is the kind of recipe you will make once and immediately add to your permanent rotation.
Helpful Tips
- Chop the peanut butter cups while cold: Pop the bag of mini peanut butter cups in the freezer for 10 minutes before chopping. Cold cups hold their shape better under the knife and stay in cleaner pieces throughout the batter.
- Do not overbake: This cake is meant to be dense and fudgy, so pull it out as soon as a toothpick comes out clean. Even a few extra minutes in the oven can push it from perfectly moist to dry.
- Let it cool before slicing: The pudding in the batter needs a little time to set after baking. Give the cake at least 15 to 20 minutes to cool in the pan so the squares hold their shape and the melted peanut butter cups have a chance to firm back up.
