Instructions
Ready to make the easiest, most indulgent cake of your life? Let’s get started!
Preheat the Oven
Start by preheating your oven to 350°F (175°C). While it’s warming up, you’ll be putting everything together, so it’s ready to go when the oven is!
Prepare the Pan
Grease a 9×13-inch baking dish with butter or cooking spray. This ensures the cake won’t stick and helps create that lovely golden crust.
Layer the Peanut Butter Cups
Cut the peanut butter cups into quarters and scatter them evenly across the bottom of your prepared baking dish. You want to make sure they’re well distributed so every bite has that delicious peanut butter and chocolate goodness.
Add the Cake Mix
Sprinkle the dry cake mix evenly over the peanut butter cups. Don’t mix it in—just sprinkle it right on top. The magic happens during baking when the cake mix turns into a gooey, fudgy layer.
Pour the Milk
Slowly pour the milk over the top of the cake mix. Again, don’t stir it. You just want the milk to soak into the cake mix, helping it cook into that irresistible texture.
Add the Butter
Cut the butter into thin slices and scatter them over the top of the cake mix. The butter will melt and create a golden, slightly crispy topping. The more butter, the more richness it adds!
Optional: Add Chocolate Chips
For that extra chocolatey goodness, sprinkle some chocolate chips over the top. You can go as heavy-handed as you like—this cake is all about indulgence!
Bake the Cake
Pop the dish into the preheated oven and bake for about 35-40 minutes, or until the top is golden brown and the cake is bubbling along the edges. The center should be set but still a bit gooey—this is what makes it so delicious.
Let It Cool Slightly
Once the cake is out of the oven, let it cool for about 10 minutes. This allows the cake to set up slightly and makes it easier to serve.
Serve and Enjoy
Scoop out a big piece and serve it warm. It’s incredible on its own, but for a real treat, top it with a scoop of vanilla ice cream or a dollop of whipped cream. The warm cake combined with the cold ice cream is seriously heaven on earth!

How to Serve Peanut Butter Cup Dump Cake
Here are a few ideas to make your Peanut Butter Cup Dump Cake even more indulgent:
- With Ice Cream: A scoop of vanilla ice cream or peanut butter ice cream makes this cake even richer and more satisfying.

- With a Cup of Coffee: This dessert pairs perfectly with your morning coffee or an afternoon espresso—especially if you’re enjoying it as a treat!
Additional Tips

- Make it your own: You can swap out peanut butter cups for other candy bars, like Snickers or Reese’s Pieces, for a new twist each time you make this cake.
- Reheat for Best Results: If you’re storing leftovers, reheat them in the microwave for 20-30 seconds to get that warm, gooey texture back.
