Posted on May 20, 2025

Peanut Butter Cup Dump Cake 🍫🥜

This decadent, no-fuss Peanut Butter Cup Dump Cake is a dreamy mashup of chocolate cake, creamy peanut butter cheesecake filling, and melty peanut butter cups—all with minimal effort! Perfect for potlucks, parties, or when you need a quick dessert fix.


Ingredients

  • 1 box chocolate cake mix (15.25 oz)

  • 1 cup creamy peanut butter

  • 1 cup milk (whole or 2%)

  • 8 oz cream cheese, softened

  • 1 cup powdered sugar

  • 1 tub (8 oz) whipped topping (Cool Whip or homemade)

  • ½ cup mini peanut butter cups, chopped (plus extra for topping)

  • ¼ cup chocolate syrup or melted chocolate (optional drizzle)


Instructions

1️⃣ Prep the Pan:

  • Preheat oven to 350°F (175°C).

  • Grease a 9×13-inch baking dish.

2️⃣ Make the Cake Layer:

  • In a bowl, mix cake mix, peanut butter, and milk until combined (batter will be thick).

  • Spread evenly into the baking dish.

3️⃣ Make the Cheesecake Layer:

  • In another bowl, beat cream cheese until smooth.

  • Add powdered sugar and mix until creamy.

  • Fold in whipped topping and chopped peanut butter cups.

  • Drop spoonfuls over the cake batter, then gently swirl with a knife (don’t overmix).

4️⃣ Bake & Chill:

  • Bake for 30-35 mins until edges are set (center may look slightly jiggly).

  • Let cool 10 mins, then refrigerate at least 2 hours (or overnight) to set.

5️⃣ Serve:

  • Drizzle with chocolate syrup and top with extra peanut butter cups.


Tips & Variations

✅ No-Bake Option: Skip baking—just layer the cake mix batter (unbaked) with the cheesecake mixture and chill. The cake mix softens into a brownie-like texture.
✅ Substitutions:

  • Use devil’s food cake mix for extra richness.

  • Swap peanut butter cups for Reese’s Pieces or chocolate chips.
    ✅ Serving Idea: Add a scoop of vanilla ice cream for the ultimate indulgence!


Why You’ll Love It:
➡️ Only 6 ingredients (plus toppings)!
➡️ Creamy + fudgy texture contrast.
➡️ Crowd-pleaser for any occasion.
