1 cup peanut butter cups, roughly chopped (about 6–8 cups)

1 cup milk

 

½ cup creamy peanut butter

 

1 cup chocolate chips (optional, for extra chocolatey goodness)

 

Powdered sugar (for dusting, optional)

 

How to Make Peanut Butter Cup Dump Cake

1. Preheat the Oven

 

Set your oven to 350°F (175°C). Grease a 9×13-inch baking dish.

 

2. Layer the Ingredients

 

Start by dumping the dry cake mix directly into the baking dish. No need to mix it beforehand!

 

Next, sprinkle the chopped peanut butter cups evenly over the cake mix.

 

3. Add the Wet Ingredients

 

In a small bowl, whisk together:

 

Milk

 

Creamy peanut butter

 

Melted butter

 

Pour this mixture evenly over the cake mix and peanut butter cups. Do not stir—it will bake into a magical, gooey cake with a crispy top!

 

4. Optional: Add Chocolate Chips

 

For an extra chocolatey punch, sprinkle chocolate chips over the top of the cake.

 

5. Bake

 

Bake for 35–40 minutes, or until the cake is golden and set. The center will be soft and gooey, just like a lava cake.

 

6. Cool & Serve

 

Let the cake cool slightly before serving (though it’s delicious warm and gooey). Dust with powdered sugar for extra flair.
