Ingredients You’ll Need
Here’s everything you’ll need to make your own Peanut Butter Cup Dump Cake:
- 1 box of yellow cake mix – The foundation of the cake, providing sweetness and structure.
- 1 cup peanut butter – Smooth or crunchy, depending on your preference.
- 1/2 cup unsalted butter, melted – Adds richness and keeps the cake moist.
- 1 cup milk – To blend everything together. Whole milk is best for creaminess.
- 1 cup semi-sweet chocolate chips – For bursts of melty chocolate goodness.
- 1/2 cup chopped peanut butter cups (about 4–6) – The star of the show, adding indulgence and texture.
- 1 teaspoon vanilla extract – To enhance the flavor profile.
- 1/2 cup powdered sugar – A sweet finishing touch for presentation and flavor.
Step-by-Step Directions
Follow these simple steps, and you’ll have a perfect dump cake ready in no time:
- Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray.
- Mix the batter: In a large bowl, combine the cake mix, peanut butter, melted butter, and milk. Stir until just combined. Don’t overmix—it’s okay if the batter looks a little lumpy.
- Spread evenly: Pour the mixture into the greased baking dish and smooth the top with a spatula.
- Add toppings: Sprinkle the semi-sweet chocolate chips and chopped peanut butter cups evenly over the batter.
- Finish with vanilla and sugar: Drizzle vanilla extract across the surface and lightly dust with powdered sugar.
- Bake for 30–35 minutes, or until golden brown and a toothpick inserted into the center comes out clean.
- Cool slightly: Let the cake rest for about 10 minutes before slicing and serving warm.
Tips for the Best Peanut Butter Cup Dump Cake
Want to make your dump cake absolutely irresistible? Here are some pro tips:

- Serve warm – This cake is at its best when slightly warm and gooey, fresh from the oven.
- Add ice cream – Vanilla ice cream or whipped cream takes this dessert to the next level.

- Overbaking – Keep an eye on the cake; overbaking will dry it out.
