Ingredients
Serves 10–12
- 1 box (15.25 oz / 432g) chocolate cake mix
- 1 can (21 oz / 595g) chocolate pie filling or chocolate fudge sauce (thicker = gooier)
- 1/2 cup (120g) creamy peanut butter
- 1/2 cup (100g) brown sugar (optional, for extra caramel-like richness)
- 1/2 cup (85g) chocolate chips (semi-sweet or dark)
- 1/2 cup (85g) peanut butter chips (optional but amazing)
- 1/2 cup (115g) unsalted butter, melted
- 1 cup (240ml) milk (or half-and-half for extra richness)
- 1 teaspoon vanilla extract
- Pinch of salt
Optional Toppings
- Crushed peanuts or chopped Reese’s-style candy
- Vanilla ice cream or whipped cream
- Chocolate syrup or warm peanut butter drizzle
Preparation Time
- Prep time: 10 minutes
- Cooking time: 40–45 minutes
- Cooling time: 10 minutes
- Total time: About 60 minutes
Step-by-Step Instructions
Step 1: Preheat and Prep
Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
Step 2: Add the Chocolate Base
Spread the chocolate pie filling (or fudge sauce) evenly in the bottom of the baking dish. This creates the gooey chocolate layer.
Step 3: Add Peanut Butter Swirls
Warm the peanut butter for 10–15 seconds in the microwave so it’s drizzle-friendly. Drop spoonfuls or drizzle peanut butter over the chocolate layer.
Step 4: Sprinkle the Cake Mix
Evenly sprinkle the dry chocolate cake mix over the top. Don’t stir—dump cakes work best layered.
Step 5: Add Chips and Flavor
Sprinkle chocolate chips and peanut butter chips (if using) over the cake mix. Add a pinch of salt for balance.
Step 6: Pour the Liquids
Whisk together milk, vanilla, and melted butter, then pour evenly over the cake mix. Try to cover as much of the surface as possible.
Step 7: Bake
Bake for 40–45 minutes, until the top looks set and slightly cracked, and the edges are bubbling. The center should still be soft and gooey.
Step 8: Cool and Serve
Let cool for 10 minutes before serving. Spoon into bowls and enjoy warm.
Serving Suggestions
- Serve warm with a big scoop of vanilla ice cream (best combo!).
- Drizzle with warm peanut butter or chocolate syrup for extra indulgence.
- Sprinkle crushed peanuts or chopped candy on top for crunch.
- Pair with fresh strawberries or banana slices to balance the richness.
- Great for parties—serve in small cups with whipped cream on top.

Tips for the Best Dump Cake
- Don’t stir the layers—the texture depends on layering.
- For a gooier cake, use fudge sauce instead of pie filling.
- If you notice dry patches of cake mix, gently drizzle a bit more milk on those spots.
- Let it rest 10 minutes so the gooey center thickens slightly.
- Want crunch? Add chopped peanuts in the last 10 minutes of baking.
Variations to Try
- Reese’s Lovers: Add chopped peanut butter cups before baking.
- Salted Version: Sprinkle flaky sea salt on top after baking.
- Banana Twist: Add sliced bananas under the cake mix for a fruity layer.
- Extra Fudgy: Mix 2 tablespoons cocoa powder into the milk before pouring.
- Dairy-Free: Use plant-based milk and dairy-free butter; skip PB chips if needed.
