How to Make Peanut Butter Cup Dump Cake Step by Step
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish to prevent sticking and make cleanup easier.
Step 2: Prepare the Batter
In a large mixing bowl, whisk together the instant chocolate pudding mix and milk until smooth and creamy.
Add the chocolate cake mix and stir until fully combined. The batter will be thick and rich.
Step 3: Add the Peanut Butter Cups
Fold 1 cup of the chopped Reese’s Peanut Butter Cups into the batter, making sure they are evenly distributed throughout the mixture.
Step 4: Transfer to the Baking Dish
Spread the batter evenly into the prepared baking dish.
Sprinkle the remaining chopped peanut butter cups over the top so they become slightly melty and delicious while baking.
Step 5: Bake Until Gooey and Delicious
Bake for 25 to 30 minutes, or until the center is set and a toothpick inserted into the middle comes out mostly clean.
The kitchen will smell rich, chocolatey, and completely irresistible.
Step 6: Cool Slightly and Serve
Allow the cake to cool for a few minutes before serving.
Serve warm with whipped cream or vanilla ice cream for the ultimate comforting dessert experience.
