How to Make Peanut Butter Cup Dump Cake
Step 1: Prepare Your Baking Dish
Start by preheating your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish to keep your Peanut Butter Cup Dump Cake from sticking and make cleanup a breeze. This prep sets the stage for a flawless bake.
Step 2: Layer the Candy Base
Scatter the chopped mini peanut butter cups and chocolate chips evenly over the bottom of the dish. This layer acts like a treasure trove of sweetness beneath the cake mix, ensuring that every slice contains delightful bits of chocolate and peanut butter.
Step 3: Add the Sweetened Condensed Milk
Drizzle the sweetened condensed milk evenly over the candy layer. This luscious step adds creamy sweetness and helps meld all the components into one harmonious dessert classic.
Step 4: Dollop the Peanut Butter
Drop spoonfuls of creamy peanut butter across the dish. These pockets of peanut butter melt into the cake as it bakes, creating a rich, nutty surprise with every bite.
Step 5: Sprinkle the Cake Mix
Generously sprinkle the yellow cake mix over the entire dish without stirring. This dry layer will crisp up when baked, contrasting beautifully with the gooey ingredients beneath.
Step 6: Pour on the Melted Butter
Pour the melted butter evenly over the cake mix. The butter’s fat is the secret to the cake’s golden-brown, buttery crust that seals in all the warmth and flavor.
Step 7: Bake to Perfection
Bake the cake for 40 to 45 minutes, until the top is golden brown and you see bubbles of goodness around the edges. This baking process transforms the simple layers into a decadently rich dessert.
Step 8: Add the Finishing Touches
Once out of the oven, let the cake cool slightly. Then, sprinkle additional chopped peanut butter candies on top and drizzle chocolate syrup if you want to make it really special. These final details elevate the cake from everyday to extraordinary.
