Rich Peanut Butter Cup Dump Cake (Print Version)

Layers of creamy peanut butter, moist chocolate cake, and gooey peanut butter cups create this indulgent dessert.

# What You'll Need:

→ Cake Base

01 - 1 box (15.25 oz) devils food chocolate cake mix
02 - 1 cup creamy peanut butter, room temperature
03 - ½ cup unsalted butter, melted
04 - 1½ cups whole milk

→ Toppings

05 - 1 cup mini peanut butter cups, unwrapped
06 - ½ cup semi-sweet chocolate chips

# How to Make It:

01 - Preheat oven to 350°F. Lightly grease a 9x13-inch baking dish with nonstick spray or butter.
02 - Spread the creamy peanut butter evenly over the bottom of the prepared baking dish.
03 - In a large mixing bowl, whisk together the chocolate cake mix, melted butter, and milk until the batter is mostly smooth (small lumps are acceptable).
04 - Pour the cake batter evenly over the peanut butter layer in the baking dish.
05 - Scatter the mini peanut butter cups and chocolate chips evenly over the top of the batter.
06 - Bake for 35–40 minutes, or until the cake is set and a toothpick inserted into the center comes out mostly clean (a few moist crumbs are fine).
07 - Remove from oven and let cool for at least 15 minutes before serving warm. For cleaner slices, allow to cool completely. Serve as is or with vanilla ice cream.
