How to Make Peanut Butter Cup Dump Cake
-
Preheat your oven to 350°F (175°C) and prepare a 9×13-inch baking dish by giving it a good spritz with non-stick spray. This helps ensure your delicious cake comes out easily once baked!

Whisk together the milk and chocolate pudding mix in a large mixing bowl until the mixture is smooth and slightly thickened. This should take just a minute or two, and the creamy texture is what you want!
-
Combine the chocolate cake mix with the pudding mixture directly, stirring gently until everything is just incorporated. Avoid overmixing; we want a tender cake!
-
Fold in most of the chopped mini Reese’s Peanut Butter Cups, leaving a few to sprinkle on top later. This adds a delightful surprise in every bite you take!
-
Pour the batter into your prepared baking dish, smoothing it out evenly. Before it goes into the oven, sprinkle the reserved Reese’s on top to create that irresistible gooey topping.
-
Bake for 25 minutes or until a toothpick inserted into the center comes out clean. The top should be set and slightly golden—your kitchen will smell heavenly!
-
Cool the cake slightly before serving it warm or at room temperature. Each slice is best enjoyed with a scoop of ice cream or a drizzle of chocolate sauce!
