Ingredients Breakdown

This Peanut Butter Cup Dump Cake makes approximately 20 slices.

Ingredients

• 1 box (15.25 oz) chocolate cake mix
• 1 box (3.4 oz) instant chocolate pudding mix
• 1¾ cups milk
• 1 package (8 oz) mini peanut butter cups, roughly chopped

Ingredient Notes

The chocolate cake mix provides the structure and deep cocoa base of the cake. The instant chocolate pudding mix enhances moisture and creates a richer, fudgier texture. Milk activates the pudding and helps bind the batter. Mini peanut butter cups bring bursts of creamy peanut butter and chocolate throughout the cake, making every slice indulgent and flavorful.

Tools & Equipment Needed

• 13 x 9 inch baking dish
• Large mixing bowl
• Whisk or spoon
• Measuring cups
• Knife and cutting board for chopping peanut butter cups
• Oven mitts
• Cooling rack (optional)

Step-by-Step Instructions

1. Preheat the oven

Preheat your oven to 180°C (350°F). Lightly spray a 13 x 9 inch baking dish with non-stick spray to prevent sticking.

2. Mix pudding base

In a large mixing bowl, whisk together 1¾ cups milk and the instant chocolate pudding mix until smooth and fully combined.

3. Add cake mix

Add the chocolate cake mix into the pudding mixture. Stir until everything is well blended. The batter will be thick—this is expected and important for the final texture.

4. Add peanut butter cups

Roughly chop the mini peanut butter cups into different-sized pieces. Fold them gently into the batter, distributing them evenly throughout.

5. Transfer to baking dish

Pour the thick mixture into the prepared baking dish. Spread it evenly so it bakes consistently.

6. Bake

Bake for 25 minutes, or until a skewer inserted into the center comes out clean with just a few moist crumbs.

7. Cool and serve

Let the cake cool slightly before serving. It is best enjoyed warm, when the peanut butter cups are still soft and slightly melted.

Tips & Variations

• Do not overmix the batter; stop once ingredients are combined
• The batter should be thick, not runny
• Chop peanut butter cups into varied sizes for texture contrast
• Add chocolate chips for extra richness
• Swap peanut butter cups for caramel-filled chocolates for variation
• Use vanilla pudding mix for a lighter chocolate flavor base
• Add chopped nuts for extra crunch if desired

Mini peanut butter cups are the star of this recipe. Their creamy peanut butter filling melts beautifully during baking, creating pockets of rich flavor throughout the cake.
