Irresistible Peanut Butter Cup Dump Cake Recipe
Introduction
This Irresistible Peanut Butter Cup Dump Cake combines rich chocolate cake with gooey pudding and chunks of peanut butter cups for a decadent treat. It’s easy to prepare and perfect for satisfying your sweet tooth without fuss.

Ingredients
- 1 box chocolate cake mix
- 1 package (3.9 oz) chocolate instant pudding mix
- 2 cups milk (preferably room temperature)
- 2 cups mini Reese’s Peanut Butter Cups, roughly chopped
Instructions
- Step 1: Preheat your oven to 350°F (175°C) and lightly grease a 9×13 inch baking dish with butter or cooking spray.
- Step 2: Empty the chocolate cake mix and instant pudding mix into a large mixing bowl, whisking them together to combine and break up any lumps.
- Step 3: Pour in the milk gradually while stirring with a wooden spoon or rubber spatula until the mixture is smooth and well combined. The batter will be thick but pourable.
- Step 4: Fold in 1½ cups of the chopped Reese’s Peanut Butter Cups, reserving the remaining ½ cup for topping. Fold gently to keep the cups from breaking down too much.
- Step 5: Transfer the batter to your prepared baking dish, spreading it evenly to the corners.
- Step 6: Sprinkle the remaining ½ cup of chopped peanut butter cups over the top of the batter.
- Step 7: Bake for 30-35 minutes, until the edges are set but the center remains slightly underdone for a gooey texture.
- Step 8: Allow the cake to cool for at least 15 minutes before serving to let it set slightly while keeping its melty texture.
Tips & Variations
- For extra crunch, sprinkle chopped peanuts on top before baking.
- You can substitute regular Reese’s cups if mini ones aren’t available, just chop them roughly.
- Serve warm with vanilla ice cream for an indulgent dessert experience.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions briefly in the microwave to restore the warm, gooey texture before serving.

Ingredients
Cake Mix & Pudding
- 1 box chocolate cake mix
- 1 package (3.9 oz) chocolate instant pudding mix
- 2 cups milk (preferably room temperature)
Peanut Butter Cups
- 2 cups mini Reese’s Peanut Butter Cups, roughly chopped
Instructions
- Preheat and Prepare: Preheat your oven to 350°F (175°C) and lightly grease a 9×13 inch baking dish with butter or cooking spray to prevent sticking.
- Combine Dry Ingredients: In a large mixing bowl, empty the chocolate cake mix and instant pudding mix, whisking them together well to combine and break up any lumps for an even texture.
- Add Milk and Mix: Gradually pour in the milk while stirring continuously with a wooden spoon or rubber spatula until the batter is smooth and thick but still pourable, ensuring a rich and gooey texture after baking.
- Fold in Peanut Butter Cups: Gently fold 1½ cups of the chopped peanut butter cups into the batter, taking care not to break them down too much so they retain their chunky texture inside the cake.
- Transfer Batter: Spread the batter evenly into the prepared baking dish, making sure it reaches all corners for uniform baking.
- Add Topping: Sprinkle the reserved ½ cup of chopped peanut butter cups evenly over the top of the batter to create pockets of melted peanut butter on the surface.
- Bake: Bake in the preheated oven for 30-35 minutes. The edges should be set while the center remains slightly underdone for that perfect gooey, pudding-like consistency.
- Cool Before Serving: Allow the cake to cool for at least 15 minutes. This resting time lets the cake set slightly while maintaining a warm, melty texture that’s irresistible.
Notes
- Do not overbake; the center should remain soft and a bit underdone for the signature gooey texture.
- Using room temperature milk helps the batter mix more smoothly without lumps.
- Gently folding in the peanut butter cups preserves their shape and texture inside the cake.
- You can substitute mini Reese’s with any similar peanut butter cup candies if preferred.
- Serve warm for the best melty peanut butter experience, optionally with a scoop of vanilla ice cream.
