How to Make Peanut Butter Cup Dump Cake
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
Step 2: Dump the Cake Mix
Spread the dry chocolate cake mix evenly across the bottom of the baking dish.
Step 3: Add the Peanut Butter
Spoon dollops of peanut butter over the cake mix. Don’t worry about spreading—it will melt into the cake as it bakes.
Step 4: Pour the Milk
Slowly pour the milk evenly over the top to moisten the cake mix.
Step 5: Add Butter & Peanut Butter Cups
Drizzle melted butter over everything, then sprinkle chopped peanut butter cups evenly on top.
Step 6: Bake
Bake for 40–45 minutes, until the top is set and the center is gooey but not liquid.
