Peanut Butter Cup Dump Cake Ingredients
For the Cake Base
- Instant Chocolate Pudding Mix – Provides creaminess and moistness; avoid cook-and-serve types for best results.
- Milk – Activates the pudding mix and adds creaminess; any dairy or non-dairy milk works.
- Chocolate Cake Mix (Dry) – Forms the structure of the cake; feel free to swap with devil’s food cake or brownie mix for a richer taste.
For the Fudgy Layer
- Creamy Peanut Butter – Adds richness and flavor; almond butter or cashew butter can be used for those with nut allergies.
- Melted Butter – Moistens the dry cake mix, creating a fudgy texture; unsalted is preferable for better flavor control.
For the Topping
- Mini Peanut Butter Cups – Enhance the chocolate-peanut flavor and provide texture; chocolate chips can be used as an alternative.
- Chopped Peanuts – Adds crunch and depth to the cake; substituting with almonds or pecans works well too.
Step‑by‑Step Instructions for Peanut Butter Cup Dump Cake
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) while you grease a 9×13-inch baking dish with non-stick spray or butter. This initial preparation is essential as it ensures the Peanut Butter Cup Dump Cake releases easily after baking, which is key to maintaining its gooey texture.
Step 2: Whisk the Pudding
In a medium mixing bowl, combine the instant chocolate pudding mix with the milk. Whisk vigorously for about 2 minutes, until the mixture thickens to a pudding-like consistency. This creamy layer will be the foundation of your dump cake, adding moisture and richness.
Step 3: Layer the Pudding
Pour the thickened pudding mixture evenly into the greased baking dish, smoothing it out with a spatula to create an even layer. This step is crucial, as it sets the stage for the delicious balance of flavors that will soon come together in your mouthwatering Peanut Butter Cup Dump Cake.
Step 4: Add the Peanut Butter
Drop spoonfuls of creamy peanut butter over the pudding layer, spreading it gently with a spatula to create an even distribution. This creates delightful pockets of flavor throughout your dump cake, ensuring that every bite is infused with that rich, nutty goodness of peanut butter.
Step 5: Sprinkle the Cake Mix
Carefully sprinkle the dry chocolate cake mix evenly over the peanut butter and pudding layers, avoiding any stirring. This ensures that the cake mix stays dry on top, allowing the moisture from the peanut butter and pudding to seep through during baking, which keeps the cake wonderfully gooey.
Step 6: Drizzle with Butter
Melt the unsalted butter and drizzle it evenly over the dry cake mix. This step is important; the melted butter will moisten the cake mix as it bakes, creating that fudgy texture that makes your Peanut Butter Cup Dump Cake so irresistibly delicious.
Step 7: Add Toppings
Scatter the mini peanut butter cups and chopped peanuts generously over the top of your cake. These toppings will add not only flavor but also a delightful crunch that beautifully contrasts with the soft layers below. They are the finishing touches to your decadent dessert.
Step 8: Bake to Perfection
Place the baking dish in the preheated oven and bake for 35-40 minutes. Keep an eye on it; the edges should be bubbling, and the center should look slightly gooey while set. This is when your Peanut Butter Cup Dump Cake transitions into a beautiful, warm dessert.
Step 9: Cool Before Serving
Once baking is complete, remove the dish from the oven and let it cool slightly for about 10 minutes. This resting time allows the cake to set and makes it easier to serve. Enjoy it warm, where the gooeyness truly shines, making it a perfect comfort dessert.
