Ingredients You’ll Need
Let’s break it down. Here’s what goes into your Peanut Butter Cup Dump Cake:
- 1 box (15.25 oz) chocolate cake mix – Use your favorite brand.
- 1 package (3.9 oz) instant chocolate pudding mix – Not cooked pudding, just the mix.
- 2 cups milk – Whole milk gives the richest flavor.
- 1/2 cup peanut butter – Smooth is classic, but chunky works if you want extra texture.
- 1 cup mini peanut butter cups, chopped – These melt into gooey little pockets of joy.
- 1/2 cup melted butter – Essential for the perfect golden top.
- 1/2 cup chocolate chips – Semi-sweet balances the sweetness.
Optional: Serve it up with vanilla ice cream or a dollop of whipped cream for that over-the-top finish.

Step-by-Step Directions
Time to get baking! Here’s exactly how to make the ultimate peanut butter cup dump cake:
1. Preheat and prep
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with nonstick spray or a light coating of butter.
2. Make the pudding base
In a mixing bowl, whisk together your instant chocolate pudding mix with the milk until it’s smooth and slightly thickened. This becomes the gooey, chocolatey foundation of your cake.
Pro tip: Don’t let it sit too long—once mixed, pour it straight into the prepared baking dish.
3. Add the dry cake mix
Now comes the magic of the “dump.” Sprinkle the dry chocolate cake mix evenly over the pudding. Don’t stir it in—just let it sit on top.
4. Pour on the butter
Drizzle your melted butter across the top of the cake mix. Try to cover as much of the surface as possible for that golden crust.
5. Drop dollops of peanut butter
Use a spoon to drop little dollops of peanut butter across the top. As it bakes, it will melt and swirl into the chocolate layers.
6. Add the candy and chips
Scatter your chopped peanut butter cups and chocolate chips over the entire dish. Press some slightly into the top for extra gooeyness.
7. Bake until bubbly
Bake for 35–40 minutes, until the top looks set but still slightly soft in the center. The edges will be bubbling, and your kitchen will smell heavenly.
8. Cool (if you can wait!)
Let the cake cool slightly before serving—it helps it firm up just a little, making it easier to scoop. Or go all in and eat it warm and messy with a spoon.
