Ingredients You’ll Need
(Serves 10-12 | Prep Time: 5 minutes | Cook Time: 40-45 minutes)
- 1 box chocolate cake mix
- 1 can (14 oz) sweetened condensed milk
- 1 cup creamy peanut butter, slightly warmed
- 1/2 cup unsalted butter, melted
- 2 cups mini peanut butter cups, chopped
- Optional: Vanilla ice cream or whipped cream for serving
How I Make Peanut Butter Cup Dump Cake (Step-by-Step)
1. Preheat and Prep
I preheat the oven to 350°F and lightly grease a 9×13-inch baking dish.
2. Layer the Goodness
I start by pouring the sweetened condensed milk into the bottom of the pan and spreading it evenly. Then I drizzle the warmed peanut butter over the top and scatter half of the chopped peanut butter cups across the surface.
3. Add the Cake Mix
Next, I evenly sprinkle the dry chocolate cake mix over everything — no mixing required.
4. Finish with Butter and More Candy
I drizzle the melted butter over the cake mix, making sure to cover as much of the surface as possible. Then I top it all off with the remaining peanut butter cups.
5. Bake
I bake for 40-45 minutes until the top is set, the edges are bubbling, and the middle is still slightly gooey. The smell of chocolate and peanut butter filling the kitchen is incredible.
6. Cool Slightly and Serve
I let the cake cool for about 10 minutes before serving it warm, scooped right out of the pan with a big spoon. It’s extra dreamy with a scoop of vanilla ice cream on top.
My Favorite Tips for Perfect Peanut Butter Cup Dump Cake
- Warm the peanut butter slightly: It makes it easier to drizzle and layer.
- Don’t stir the layers: The magic of a dump cake is letting the layers bake and meld together on their own.
- Use mini peanut butter cups: They melt nicely and give you little bursts of peanut butter in every bite.
- Drizzle extra melted peanut butter on top after baking: It’s totally optional, but so good.
- Store leftovers covered at room temperature or refrigerate for up to 3 days: Reheat in the microwave for that gooey texture again.
What I Serve with Peanut Butter Cup Dump Cake
This dessert is rich enough to stand on its own, but here are a few ways I love to enjoy it:
- A big scoop of vanilla ice cream for the perfect hot-and-cold combo
- Fresh whipped cream for a light, airy finish
- A drizzle of caramel sauce or hot fudge
- Crushed peanuts or chocolate shavings on top for extra texture
