- 14 oz sweetened condensed milk: Adds creamy sweetness and moisture that melds the layers together.
- 1 cup creamy peanut butter: Forms a rich, nutty base that brings the signature peanut flavor.

Within about an hour, including cooling time, you’ll have a warm, gooey dessert brimming with sweet and nutty flavors that’s perfect for sharing (or not!).
1. Preheat your oven to 350°F and lightly grease a 9×13-inch baking pan with cooking spray or melted butter for a nonstick surface.
2. Spread the 1 cup creamy peanut butter evenly across the bottom of the prepared pan, ensuring a smooth base layer.
3. Pour the 14 oz sweetened condensed milk over the peanut butter layer, then smooth it out with a spatula for even coverage.
4. Sprinkle the 15.25 oz yellow cake mix evenly over the condensed milk, shaking gently to cover every spot.
5. Arrange the 1/2 cup sliced unsalted butter pieces on top of the cake mix so they melt into the batter while baking.
6. Scatter the 1 cup chopped peanut butter cups across the surface, adding bursts of chocolatey goodness.
7. Bake for 35–40 minutes until the top turns golden brown and the butter has melted into the cake mix for gooey pockets.

Frequently Asked Questions
Ready to tackle your first Peanut Butter Cup Dump Cake? Here are some quick answers to the questions you might have:
- How long does it take to prepare and bake the Peanut Butter Cup Dump Cake?
Preparation takes about 10 minutes to grease the pan, spread layers, and chop peanut butter cups. Baking requires 35–40 minutes at 350°F, plus a 15-minute cooling period, totaling about 1 hour.
- Can I use crunchy peanut butter instead of creamy?
Yes. Swapping crunchy peanut butter adds extra texture. Spread it the same way in step 2. Baking time and results remain the same since only the nut pieces differ.
- How do I know when the dump cake is fully baked?
The cake is done when the top turns golden brown, the butter pieces have melted into the cake mix, and you see bubbling around the edges. A toothpick inserted into the center will come out mostly clean, with only a few moist crumbs.
- What variations can I make for a chocolate twist?
For extra chocolate flavor, sprinkle ½ to ¾ cup mini chocolate chips evenly over the top before baking. You can also fold in ½ cup cocoa powder with the yellow cake mix, though this may require adding a tablespoon of milk to maintain moisture.
- How should I store leftovers and how long will they last?
Cover the cooled cake tightly with plastic wrap or aluminum foil and refrigerate. It will stay fresh for up to 3 days. Reheat individual slices in the microwave for 10–15 seconds to restore warmth.
- Can I freeze the dump cake for later?
Yes. Once completely cooled, slice the cake, wrap each piece in plastic wrap, then place in an airtight container or freezer bag. Freeze for up to 2 months. Thaw in the refrigerator overnight and warm briefly in the microwave before serving.
- Is it possible to prepare this dump cake ahead of time?
You can assemble all layers in the pan, cover tightly, and refrigerate for up to 12 hours before baking. Let the pan sit at room temperature for 20 minutes before placing it in the preheated oven to ensure even baking.
- What are the best serving suggestions for this cake?
Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream to complement the rich peanut butter layers. Fresh berries or sliced bananas also pair nicely for a fruity contrast.
