Do I Need a Cake Mix or Brownie Mix?

For this particular dump cake, brownie mix is the way to go. It gives the dessert that dense, fudgy texture that pairs perfectly with the gooey caramel and soft mini peanut butter cups. While cake mix could work in a pinch, it won’t deliver the same richness or structure. Stick with a good quality fudge brownie mix to get the right consistency.

Ingredients for the Peanut Butter Cup Dump Cake

Brownie Mix – Forms the base layer. Choose a fudge-style mix for extra decadence.

Eggs and Oil – Essential to prepare the brownie mix to get that rich, chewy texture.

Milk – Adds moisture and makes the brownies extra tender.

Mini Peanut Butter Cups – The star of the show. They melt slightly into the brownies while keeping little pockets of peanut butter joy.

Caramel Sauce – Swirled in before baking and drizzled on top for that ooey-gooey, sticky-sweet finish.

Chocolate Chips or Chocolate Sauce – Optional, but a drizzle of melted chocolate on top takes the indulgence to the next level.

Crushed Cookies or Graham Crackers – Sprinkled on top for a little crunch.

How To Make the Peanut Butter Cup Dump Cake

Step 1: Prep Your Pan

Preheat your oven to 350°F and grease a 9×13 baking dish. This ensures the brownie base doesn’t stick and lifts out smoothly.

Step 2: Make the Brownie Base

In a large mixing bowl, prepare the brownie mix according to the package instructions using eggs, oil, and milk. Pour the batter evenly into the prepared baking dish.

Step 3: Layer the Goodies

Evenly sprinkle half of the mini peanut butter cups over the brownie batter. Add small spoonfuls of caramel sauce across the top and gently swirl with a knife for a marbled effect.

Step 4: Bake

Bake in the preheated oven for about 30–35 minutes, or until a toothpick inserted comes out mostly clean with a few moist crumbs.

Step 5: Decorate and Serve

While the cake is still warm, drizzle with melted chocolate or chocolate sauce. Scatter the remaining peanut butter cups and crushed cookies on top. Serve warm for maximum gooeyness or allow to cool and cut into squares.

Serving and Storing This Delicious Dessert

Peanut Butter Cup Dump Cake is best served warm when the chocolate is melty and the caramel is oozy. For extra indulgence, add a scoop of vanilla ice cream or a dollop of whipped cream. To store leftovers, cover tightly and keep in the fridge for up to 4 days. Reheat slices in the microwave for that just-baked warmth.
