Decadent Peanut Butter Cup Dump Cake with a scoop removed, showcasing gooey chocolate and peanut butter layers.

Decadent Peanut Butter Cup Dump Cake

This incredibly easy 4-ingredient dump cake features rich chocolate cake, creamy peanut butter, and an abundance of chopped peanut butter cups, baked to gooey perfection.

  • Total Time: 45 minutes
  • Yield: 8-10 servings 1x

Ingredients

Scale

1 box (15.25 oz) chocolate cake mix
1 cup creamy peanut butter
1 cup milk
1 cup chopped peanut butter cups (such as Reese’s)
1/2 cup unsalted butter, melted
1 cup chocolate chips (optional)
1/2 cup chopped nuts (optional, for added crunch)

Instructions

Step 1: Preheat your oven to 350°F (175°C) and generously grease a 9×13-inch baking dish.
Step 2: In a large mixing bowl, combine the chocolate cake mix, creamy peanut butter, and milk. Stir until just combined; do not worry about small lumps.
Step 3: Gently fold in the chopped peanut butter cups and chocolate chips (if using) until they are evenly distributed throughout the batter.
Step 4: Pour the cake batter into the prepared baking dish, spreading it evenly with a spatula.
Step 5: Drizzle the melted unsalted butter evenly over the top of the cake batter. If desired, sprinkle chopped nuts over the top for added texture and crunch.
Step 6: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean.
Step 7: Allow the dump cake to cool for about 10-15 minutes before serving. This brief cooling period helps the cake set slightly, making it easier to scoop and enjoy. Serve warm.

Notes

This dump cake is best served warm with a scoop of vanilla ice cream or a dollop of whipped cream for an extra special treat!
