Peanut Butter Cup Dump Cake

This Peanut Butter Cup Dump Cake is the easiest way to satisfy a chocolate and peanut butter craving with minimal fuss. Rich, fudgy, and just a touch gooey, it combines the deep cocoa flavor of a boxed chocolate cake mix with creamy peanut butter folded into the batter. The top bakes up slightly crisp while the interior stays tender, and pockets of melted chocolate chips add bursts of intense chocolate in every bite. The aroma while baking is warm and nostalgic, equal parts bakery and home kitchen. This recipe is perfect for casual weeknight dessert, potlucks, or whenever you need a crowd-pleasing sweet without a lot of effort.

Ingredients

1 box (15.25 oz) chocolate cake mix, use your favorite brand for consistent chocolate flavor and structure.
1 cup creamy peanut butter, adds richness and peanut butter flavor while keeping the cake moist.
3 large eggs, bind the batter and add structure and tenderness.
1 cup milk, helps dissolve the cake mix and creates a smooth batter; whole milk gives richer results.
1 cup chocolate chips, provide pockets of melted chocolate and extra texture on top.
Powdered sugar (for dusting), optional finish that adds a delicate sweetness and pretty presentation.

Step-by-Step Instructions

Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish lightly to prevent sticking.
In a large mixing bowl, combine the chocolate cake mix, creamy peanut butter, eggs, and milk. Use a whisk or electric mixer and mix well until the batter is smooth and fully combined. Tip: Scrape the sides of the bowl to ensure no dry mix remains.
Pour the batter into the greased 9×13 inch baking dish, spreading it evenly with a spatula so the cake cooks uniformly.
Sprinkle the chocolate chips evenly over the top of the batter. Try to distribute them so each slice gets some chips.
Bake in the preheated oven for 30 to 35 minutes or until a toothpick inserted into the center comes out clean. Start checking at 30 minutes to avoid overbaking.
Once baked, let the cake cool slightly in the baking dish for 10 to 15 minutes. This short rest helps the cake set and makes serving cleaner.
Dust with powdered sugar before serving. Enjoy!
