Ingredients

Scale

🛒 Ingredients (for one 9×13-inch pan):

For the Cake:

  • 1 box (15.25 oz) chocolate cake mix

  • 1 cup (2 sticks) unsalted butter, melted

  • 1 can (14 oz) sweetened condensed milk

  • 1 teaspoon vanilla extract

For the Topping:

  • 1 cup toffee bits or chopped Heath bars

  • ½ cup chopped pecans or walnuts (optional)

  • ½ cup caramel sauce or dulce de leche

  • ½ cup chocolate chips


Instructions

📝 Instructions:

Step 1: Preheat and Prepare Pan
Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish.

Step 2: Layer Ingredients
Sprinkle half of the cake mix evenly in the pan. Pour melted butter over the cake mix; it will look dry at first but will absorb the butter as it bakes.

Drizzle sweetened condensed milk evenly over the top, then sprinkle toffee bits, nuts (if using), and chocolate chips. Finish with caramel sauce drizzled on top.

Step 3: Bake
Bake for 35–40 minutes, or until the top is golden and bubbly. A toothpick inserted in the center will come out with some gooey crumbs but no raw batter.

Step 4: Cool and Serve
Allow to cool for at least 15 minutes before serving. Optionally, top with whipped cream or extra caramel drizzle for a richer dessert experience.

Notes

  • Variations: Try substituting chocolate cake mix with devil’s food cake for extra richness.

  • Make-Ahead: Prepare the dump cake a day ahead and warm slightly before serving for maximum gooeyness.

  • Texture Tip: For a “poke cake” effect, poke holes in the cake after baking and drizzle additional caramel or chocolate sauce into the holes.
