Step‑by‑Step Instructions for Peanut Butter Cup Dump Cake
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). While it warms up, generously grease a 9×13-inch baking dish with butter or cooking spray. This ensures that your decadent Peanut Butter Cup Dump Cake easily releases from the pan after baking, allowing for perfect slices and a lovely presentation when you serve it.
Step 2: Create the Cake Base
Carefully sprinkle the chocolate fudge cake mix evenly across the greased baking dish. Avoid stirring the mix; this layer acts as the foundation for your cake. Enjoy the rich chocolate aroma wafting up as you envision the melt-in-your-mouth joy awaiting you in just a few steps.
Step 3: Make the Pudding Layer
In a large mixing bowl, whisk together the instant chocolate pudding mix and whole milk until the mixture is smooth and free of lumps. This step only takes about 1-2 minutes; the pudding’s creamy consistency is vital in adding moisture. Pour the pudding mixture gently over the cake mix, ensuring even coverage without stirring.
Step 4: Add Butter for Richness
Melt the unsalted butter and drizzle it over the pudding layer. This step infuses your Peanut Butter Cup Dump Cake with extra richness that complements the chocolate beautifully. Watch as the butter cascades down, adding a golden sheen to your dessert’s top layer.
Step 5: Top with Chocolate and Peanut Butter Cups
Scatter the semi-sweet chocolate chips and mini peanut butter cups evenly over the surface, making sure every bite will be a delightful combination of flavors. This generous layer of toppings will create a luscious texture and irresistible treat once baked.
Step 6: Drizzle with Caramel
Now it’s time to enhance your creation! Drizzle the caramel sauce over the entire surface of the cake, allowing the sweet, gooey goodness to seep into the layers beneath. For those wanting extra moisture, you can also drizzle sweetened condensed milk at this stage for an even creamier finish.
Step 7: Add Crunchy Topping
Finish your layering with a generous sprinkle of crushed graham crackers or Biscoff cookies. This crunchy topping provides a delightful contrast to the gooey layers below and adds a lovely texture to the final Peanut Butter Cup Dump Cake experience.
Step 8: Bake to Perfection
Place your prepared cake in the preheated oven and bake for 35 to 40 minutes. Look for bubbling edges and a slightly jiggly center as key indicators of doneness. If the top browns too quickly, don’t hesitate to tent it with foil for the remainder of baking.
Step 9: Cool and Serve
Once baked, remove the Peanut Butter Cup Dump Cake from the oven and allow it to rest for 10 to 15 minutes. This waiting period helps the layers settle and makes cutting easier. Optionally, you can sprinkle additional caramel over the top just before serving for a beautiful finishing touch.

Make Ahead Options
These Peanut Butter Cup Dump Cakes are perfect for busy weeknights or spontaneous gatherings! You can prepare the cake base (chocolate fudge cake mix) and pudding layer (instant chocolate pudding mix with milk) up to 24 hours in advance, simply layering them in the baking dish and covering tightly to refrigerate. The mini peanut butter cups and caramel sauce can also be prepped ahead—slice the peanut butter cups and store them separately to maintain their shape. When you’re ready to bake, simply layer the toppings and drizzle with caramel before placing it in the preheated oven. This will ensure your cake is just as delicious and indulgent, saving you valuable time while still delighting everyone with a warm, gooey dessert!
