Step‑by‑Step Instructions for Peanut Butter Cup Dump Cake
Step 1: Preheat Oven
Begin by preheating your oven to 175°C (350°F). While the oven is warming, grease a 9×13-inch baking dish with non-stick spray or butter to prevent the cake from sticking. This step ensures that your Peanut Butter Cup Dump Cake will have a lovely, tender texture as it bakes.
Step 2: Layer Ingredients
Spread a generous layer of creamy peanut butter evenly across the bottom of the greased baking dish. This luscious base will provide creamy richness to the cake. Next, sprinkle half of your chopped peanut butter cups over the peanut butter layer for added chocolatey bites.
Step 3: Add Milk
Pour the sweetened condensed milk over the peanut butter cups, ensuring it’s evenly distributed. This will create a delightfully gooey center as the cake bakes. The milk seeps through the layers, enhancing the overall texture and flavor of your Peanut Butter Cup Dump Cake.
Step 4: Add Cake Mix
Carefully spread the dry chocolate cake mix over the layered ingredients, making sure it covers everything without mixing. This layering technique is key to achieving that signature dump cake texture, where each bite is a delightful surprise of chocolate and peanut butter goodness.
Step 5: Drizzle Butter
Melt your unsalted butter and pour it evenly over the top of the dry cake mix. Try to cover as much of the surface as possible, allowing the butter to seep into the cake mix as it bakes to create a golden, crispy top. This step is crucial for that irresistible crunch!
Step 6: Top
Sprinkle the remaining chopped peanut butter cups and milk chocolate chips generously over the top of the melted butter layer. These toppings will melt and create a beautiful, oozy finish, adding to the rich flavors and textures of the Peanut Butter Cup Dump Cake.
Step 7: Bake
Place the prepared baking dish in the preheated oven and bake for 35–40 minutes. You’ll know it’s ready when the edges are slightly crisped and the center is bubbly. Watch closely, as this will ensure that every bite of your dump cake is perfectly gooey yet set.
Step 8: Cool
Once baked, remove the Peanut Butter Cup Dump Cake from the oven and allow it to cool for 10–15 minutes. This short cooling period will help the center set while still keeping it warm and inviting for serving. Serve with whipped cream or vanilla ice cream for the ultimate dessert experience!
