1. Preheat the Oven

• Set your oven to 350°F (175°C).

• Grease a 9×13-inch baking dish with nonstick spray or butter.

2. Make the Cake Batter

• In a large bowl, mix together:

  • 1 box chocolate cake mix

  • ½ cup vegetable oil

  • 1 cup milk

  • 3 large eggs

  • 1 tsp vanilla extract

• Stir until well combined and smooth.

3. Layer the Cake

• Pour half of the cake batter into the baking dish and spread evenly.

• Drop spoonfuls of creamy peanut butter over the batter.

• Sprinkle half of the chocolate chips and chopped peanut butter cups on top.

4. Add Final Layers

• Pour the remaining batter over the top and gently smooth it out.

• Top with the remaining chocolate chips and peanut butter cups.

5. Bake to Perfection

• Bake in the preheated oven for 30–35 minutes.

• A toothpick inserted into the center should come out mostly clean, with some gooey bits from the chocolate.

6. Cool and Serve

• Allow the cake to cool for 10–15 minutes before slicing.

• Optional: Dust with powdered sugar for extra flair.

• Serve warm for ultimate gooey goodness—or chill and enjoy firm squares.
