Step‑by‑Step Instructions for Peanut Butter Cup Dump Cake
Step 1: Prepare Peanut Butter Mixture
In a mixing bowl, combine sweetened condensed milk, milk, creamy peanut butter, and vanilla extract. Use a whisk to blend until the mixture is smooth and creamy, about 2 minutes. This delicious concoction will serve as the rich base for your Peanut Butter Cup Dump Cake, ensuring every bite is infused with that irresistible peanut butter flavor.
Step 2: Prepare Baking Dish
Preheat your oven to 350°F (175°C). While the oven warms up, take a 9×13 inch baking dish and grease it liberally with butter or cooking spray. This prevents sticking and allows for easy serving of your decadent Peanut Butter Cup Dump Cake once it’s baked to perfection.
Step 3: Assemble Dump Cake
Pour the prepared peanut butter mixture evenly into the greased baking dish, ensuring the bottom is completely covered. Next, sprinkle the dry chocolate cake mix evenly over the peanut butter layer, allowing the flavors to meld together during baking. Lastly, drizzle melted butter over the top of the cake mix, which will help create a crispy, golden crust.
Step 4: Add Peanut Butter Cups
Take unwrapped mini peanut butter cups and scatter them generously across the top of the cake mix. Press each peanut butter cup down slightly to embed them just beneath the surface. This step helps them melt into the cake while baking, creating gooey pockets of peanut butter goodness in your delicious dessert.
Step 5: Bake
Slide the baking dish into the preheated oven and let it bake for 30-35 minutes. Keep an eye on it, and check for doneness by inserting a toothpick in the center; it should come out with a few moist crumbs attached. The top should be golden brown and slightly bubbling, indicating your Peanut Butter Cup Dump Cake is ready to shine.
Step 6: Cool
Once baked, carefully remove the cake from the oven and allow it to cool for about 15-20 minutes on a wire rack. This cooling time is crucial as it helps the cake set up a bit, making it easier to cut into squares when you’re ready to serve this scrumptious treat to your family and friends.
Step 7: Serve
To serve your warm Peanut Butter Cup Dump Cake, drizzle with optional chocolate syrup for added flair and flavor. Pair it with a dollop of whipped cream or a scoop of vanilla ice cream to enhance the experience. Dive into this decadent dessert, and prepare to savor every delightful bite!
