Description

This Reese’s peanut butter earthquake cake is a gooey, rich dessert explosion packed with chocolate, peanut butter, and melty candy swirls. With a chocolate cake base and pockets of sweet cream cheese and Reese’s cups, it’s the ultimate indulgence for peanut butter lovers and guaranteed to wow a crowd.


Ingredients

  • For the Cake:
  • 1 box chocolate cake mix (plus ingredients listed on the box: usually eggs, oil, and water)
  • 8 oz cream cheese, softened
  • ½ cup unsalted butter, melted
  • 2 cups powdered sugar
  • ½ cup creamy peanut butter
  • 1 cup chopped Reese’s peanut butter cups
  • ½ cup chocolate chips
  • Optional: ½ cup peanut butter chips or chopped peanuts

Instructions

  1. Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch baking pan.

  2. Prepare the chocolate cake batter as directed on the package. Spread evenly in the prepared pan.

  3. In a separate bowl, beat cream cheese, melted butter, powdered sugar, and peanut butter until smooth.

  4. Drop large spoonfuls of the cream cheese mixture over the cake batter. Swirl gently with a knife or spatula.

  5. Sprinkle chopped Reese’s and chocolate chips over the top. Press them in slightly.

  6. Bake for 35–40 minutes, until the edges are set and the center is slightly jiggly.

  7. Cool for 20–30 minutes before slicing. Best served warm, but holds shape once cooled.


Notes

  • For a brownie version, substitute a boxed fudge brownie mix for the chocolate cake mix.
  • Add a drizzle of caramel or Nutella for extra richness.
  • Use a swirl technique for a marbled look—don’t fully blend the cream cheese layer into the batter.
