Ingredients:

Here’s what you’ll need for this ultra-decadent dump cake:

1 box of chocolate cake mix
1 cup creamy peanut butter
1 cup milk (whole milk preferred)
3 large eggs
1/2 cup butter, melted
1 teaspoon vanilla extract
1 cup chocolate chips (semi-sweet or milk chocolate)
1 cup peanut butter cups, chopped (Reese’s work best!)
1 cup powdered sugar (optional, for icing)
2-3 tablespoons of milk (optional, for icing)

Step-by-Step Instructions:

Step 1: Prep Your Oven and Pan

Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish with butter or non-stick spray.

Step 2: Make the Cake Batter

In a large mixing bowl, combine the chocolate cake mix, milk, eggs, melted butter, and vanilla extract. Stir until the batter is smooth and there are no dry lumps.

Step 3: Layer the First Half

Pour half of the cake batter into the prepared baking dish. Spread it evenly using a spatula.

Step 4: Add the Peanut Butter Goodness

Drop spoonfuls of peanut butter over the batter. Don’t worry about spreading it—just scatter it randomly.
Now, sprinkle half of the chocolate chips and half of the chopped peanut butter cups on top.

Step 5: Finish the Layers

Pour the remaining batter over the top. Gently spread it to cover the peanut butter and candy pieces.
Then, sprinkle the remaining chocolate chips and chopped peanut butter cups on top.

Step 6: Bake to Perfection

Bake the cake for 30 to 35 minutes, or until a toothpick inserted in the center comes out mostly clean. A few gooey crumbs are okay!

Step 7: Optional Icing

If you want to make it extra special, mix 1 cup of powdered sugar with 2–3 tablespoons of milk to create a quick icing. Drizzle over the cooled cake for a sweet finish.

Pro Tips for Best Results:

Don’t overmix the batter—just stir until combined.
Use room-temperature ingredients for best texture.
For a salty-sweet twist, sprinkle a pinch of sea salt on top before baking.
Let the cake cool slightly before cutting—it firms up as it rests.
