Tips for the Best Decadent Peanut Butter Cup Dump Cake
While this recipe is incredibly forgiving, a few tips can help you achieve dump cake nirvana:
- Don’t Overmix: When combining the cake mix, peanut butter, and milk, stir just until combined. A few lumps are perfectly fine and will bake out.
- Quality Peanut Butter: Use a creamy peanut butter that you enjoy the taste of, as its flavor really shines through. If you prefer a bit of crunch, feel free to use crunchy peanut butter.
- Even Butter Drizzle: Drizzling the melted butter evenly over the top ensures a perfectly golden and crisp crust across the entire cake.
- Serve Warm: This dump cake is absolutely divine served warm, ideally with a scoop of Creamy Homemade Vanilla Ice Cream or a dollop of fresh whipped cream.

FAQs
What is a dump cake?
A dump cake is a delightfully simple dessert where ingredients are ‘dumped’ into a baking dish without much mixing. It typically involves a cake mix, fruit, and butter, creating a gooey, cobbler-like consistency once baked.
Can I use a different cake mix flavor for this dump cake?
Absolutely! While chocolate cake mix pairs perfectly with peanut butter, you could experiment with a yellow, vanilla, or even a devil’s food cake mix for a slightly different flavor profile. The key is to match it with the creamy peanut butter and peanut butter cups.
How should I store leftover Peanut Butter Cup Dump Cake?
Once cooled, cover the baking dish tightly with plastic wrap or transfer leftovers to an airtight container. It can be stored at room temperature for up to 2 days, or refrigerated for up to 5 days. Reheat gently in the microwave for a warm, gooey treat.
What are some optional toppings for this dump cake?
This dump cake is fantastic on its own, but you can elevate it with a scoop of vanilla ice cream, a dollop of whipped cream, a drizzle of chocolate syrup, or even a sprinkle of extra chopped peanut butter cups before serving.

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
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.
