Cake Batter

  • 1 package chocolate cake mix (15.25 oz)
  • 1 cup water
  • 1/2 cup vegetable oil
  • 3 large eggs Room temperature for best results

Peanut Butter Mixture

  • 1 cup creamy peanut butter
  • 1 cup powdered sugar

Mix-Ins

  • 1 cup Reese’s Peanut Butter Cups, chopped
  • 1 cup chocolate chips
  • 1 cup milk For a creamy texture

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan.
  • In a large mixing bowl, combine the chocolate cake mix, water, vegetable oil, and eggs. Mix until smooth and well combined.
  • In another bowl, mix the peanut butter with powdered sugar until smooth.

Layering

  • Pour half of the chocolate cake batter into the prepared baking pan.
  • Spoon dollops of the peanut butter mixture on top, then sprinkle half of the chopped Reese’s and chocolate chips.
  • Pour the remaining cake batter over the top and finish with the rest of the peanut butter, Reese’s, and chocolate chips.
  • Use a knife to swirl the mixtures together lightly, creating the 'earthquake' effect.

Baking

  • Place the pan in the preheated oven and bake for 30-35 minutes, or until a toothpick comes out clean.
  • Let the cake cool in the pan before slicing.

Notes

For best results, measure ingredients accurately and allow eggs and milk to come to room temperature before mixing. Add nuts or drizzle extra chocolate or caramel sauce for richness.
