Step‑by‑Step Instructions for Peanut Butter Cup Dump Cake
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter to ensure easy removal after baking. The greased surface will help form a lovely crust on your Peanut Butter Cup Dump Cake. Set it aside as you prepare the ingredients, allowing the oven to reach the perfect baking temperature for a beautifully cooked cake.
Step 2: Spread the Peanut Butter
Using a spatula, spread a generous layer of creamy peanut butter evenly across the bottom of the greased baking dish. This rich base will provide a mouthwatering foundation for your dump cake, ensuring that every bite is filled with that delightful peanut butter flavor. Aim for an even layer to create a consistent texture in the final bake.
Step 3: Add Peanut Butter Cups
Sprinkle half of the chopped peanut butter cups over the peanut butter layer, distributing them evenly. As you create this tasty layer, envision the rich bursts of chocolate and peanut butter flavor that will melt together during baking. This part is key for ensuring that your Peanut Butter Cup Dump Cake has those delightful pockets of sweetness throughout.
Step 4: Drizzle the Sweetened Condensed Milk
Pour the sweetened condensed milk evenly over your layered ingredients, ensuring every part is coated. This will help to keep your dump cake moist and add a luscious sweetness throughout. Watch as the milk begins to seep into the layers below, creating a tantalizing combination of flavors as it bakes.
Step 5: Sprinkle the Cake Mix
Next, sprinkle the dry chocolate cake mix evenly over the entire surface, without mixing it with any of the previous layers. This no-mix technique is what makes this Peanut Butter Cup Dump Cake a cinch to prepare. Make sure to cover all areas so that the chocolate flavor permeates all layers as it bakes.
Step 6: Drizzle the Melted Butter
Melt the unsalted butter and drizzle it generously over the top of the cake mix. This will moisten the cake mix and create a wonderfully crisp top as it bakes. Pay attention to the coverage to ensure that every speck of the cake mix has a chance to combine with the delicious flavors below, resulting in a rich and delectable dessert.
Step 7: Top with More Treats
Now, sprinkle the remaining chopped peanut butter cups and milk chocolate chips evenly on top of the cake mix. This will add texture and ensure that every slice of your Peanut Butter Cup Dump Cake is bursting with delicious chocolate and peanut butter goodness. You can also add additional chocolate chips if you want an extra decadent touch.
Step 8: Bake to Perfection
Place the baking dish in the preheated oven and bake for 35-40 minutes. You’ll know it’s done when the edges are bubbling and the top is slightly crisp. The aroma of melting chocolate and peanut butter wafting through your kitchen is a sure sign that you’re on the right track to a fantastic dessert.
Step 9: Cool and Serve
Allow the Peanut Butter Cup Dump Cake to cool for 10-15 minutes before serving. This slight cooling period will help maintain the gooey texture while making it easier to cut into squares. Serve warm for the best experience, optionally adding whipped cream or vanilla ice cream for an indulgent treat that will have everyone coming back for seconds.
