How to Make Peanut Butter Cup Dump Cake

1. Preheat Oven

Preheat your oven to 350°F (175°C).
Grease a 9×13 inch baking dish to prevent sticking.

2. Mix the Batter

In a large mixing bowl, combine 1 box chocolate cake mix, 1 cup peanut butter, 1/2 cup melted butter, and 1/2 cup milk.
Stir until everything is well combined and a thick batter forms.

3. Fold in the Goodies

Gently fold in 1 cup mini peanut butter cups and 1/4 cup chocolate chips.

Make sure they’re evenly distributed for maximum gooeyness in every bite!

4. Dump and Spread

Pour the batter into the prepared baking dish.
Spread it out evenly with a spatula.

5. Bake

Bake in the preheated oven for 25-30 minutes, or until the edges are set and a toothpick inserted in the center comes out with moist crumbs.
The center should be slightly gooey—don’t overbake for the best texture!

6. Cool and Serve

Let the cake cool for at least 10-15 minutes before serving.
Serve warm for a gooey, melty experience, or chilled for a fudgier texture.

What to Serve with Peanut Butter Cup Dump Cake

Vanilla Ice Cream: A scoop of ice cream adds the perfect creamy contrast.

Whipped Cream: Light and fluffy, it balances out the rich chocolate and peanut butter.
Chocolate Sauce: Drizzle on top for an extra layer of chocolatey goodness.
Chopped Peanuts: Add a salty, crunchy topping for extra texture.

Tips for Making the Best Dump Cake

Use Creamy Peanut Butter: For a smooth, consistent texture throughout the cake.
Don’t Overbake: Keep the center slightly gooey for that perfect dump cake texture.
Get Creative with Toppings: Add chopped peanut butter cups or a drizzle of caramel sauce.

Serve Warm or Chilled: Both ways are delicious, but the texture changes—warm is gooey, and chilled is fudgy.
