Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Chocolate cake mix
Eggs
Milk
Butter (melted)
Creamy peanut butter
Sweetened condensed milk
Mini peanut butter cups (halved or chopped)
Chocolate chips (optional)
Whipped topping or ice cream (for serving)

Directions

I preheat my oven to 350°F (175°C) and grease a 9×13-inch baking dish.
In a large mixing bowl, I combine the cake mix, eggs, milk, melted butter, and peanut butter until everything is smooth and blended.
I fold in half of the chopped peanut butter cups and chocolate chips, then pour the batter into the prepared baking dish.
I drizzle sweetened condensed milk evenly over the top of the batter.
I sprinkle the remaining peanut butter cups and a few extra chocolate chips over the top.
I bake the cake for 30–35 minutes, or until the edges are set and the center is still slightly gooey.
After letting it cool slightly, I scoop and serve warm with whipped topping or ice cream.

Servings and timing

This recipe serves around 10 to 12 people. It takes me about 10 minutes to prep, and the cake bakes for 30 to 35 minutes. If I let it cool slightly before serving, it’s ready to devour in just under 45 minutes.

Variations

I sometimes mix in chopped pretzels or crushed cookies for a salty-sweet crunch. For a more intense peanut butter flavor, I swirl extra peanut butter on top before baking. I’ve also tried it with a brownie mix instead of cake mix when I want something even fudgier. If I’m serving kids, I use mini peanut butter cups for fun bursts of flavor in every bite.

storage/reheating

I store leftovers covered in the fridge for up to 4 days. To reheat, I scoop a serving into a microwave-safe bowl and warm it for about 30 seconds until gooey again. It’s just as dreamy the second time around—especially with a scoop of vanilla ice cream on top.

FAQs

Can I use a different type of cake mix?

Yes, I’ve made this with fudge, devil’s food, and even yellow cake mix. Each one gives it a slightly different vibe, but it’s always delicious.

Do I need to use sweetened condensed milk?

The condensed milk adds richness and that gooey texture I love. If I skip it, the cake won’t be as moist or indulgent.

Can I make this ahead of time?

Absolutely. I bake it the day before and warm it up when I’m ready to serve. It reheats beautifully in the oven or microwave.

What’s the best way to serve this dump cake?

I love serving it warm with a scoop of vanilla ice cream or a generous spoonful of whipped topping. It’s great cold too, especially the next day.

Can I make this in a slow cooker?

Yes, I’ve made it in a slow cooker on low for about 2–3 hours. I just keep an eye on it so the edges don’t burn and the center stays gooey.

This 1-Bowl Peanut Butter Cup Dump Cake is pure dessert comfort—warm, melty, and packed with chocolate and peanut butter goodness.
