Ingredients
- 1 box (15.25 oz) chocolate cake mix

- 1 cup milk (any kind works!)
- 1/2 cup creamy peanut butter

Instructions
- Step 1: In a large bowl, combine the sweetened condensed milk, milk, peanut butter, and vanilla extract. Mix thoroughly until the mixture is smooth and creamy.
- Step 2: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish to prevent sticking.
- Step 3: Pour the peanut butter mixture evenly into the prepared baking dish. Sprinkle the chocolate cake mix evenly over the top of the peanut butter mixture.
- Step 4: Drizzle the melted butter evenly over the cake mix layer to help it bake into a moist crumb topping.
- Step 5: Sprinkle the unwrapped mini peanut butter cups evenly over the top, pressing them down lightly into the batter.
- Step 6: Bake the dump cake in the preheated oven for 30 to 35 minutes, or until the top is golden brown and a toothpick inserted into the center comes out with moist crumbs attached.
- Step 7: Allow the cake to cool for 15 to 20 minutes before serving to help it set.
- Step 8: Optionally, drizzle with chocolate syrup and serve warm with whipped cream or vanilla ice cream for an extra indulgent treat.
Tips & Variations

- For a dairy-free version, substitute sweetened condensed coconut milk and a non-dairy milk.

- 1 cup milk (any kind works!)
- 1/2 cup creamy peanut butter
- 1 teaspoon vanilla extract
Other Ingredients

Instructions
- Prepare Peanut Butter Mixture: In a large bowl, combine sweetened condensed milk, milk, creamy peanut butter, and vanilla extract. Mix thoroughly until the mixture is smooth and well combined.
- Prepare Baking Dish: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish to prevent sticking.
