Ingredients

Scale

Cake Batter

  • 1 box chocolate cake mix
  • 1 cup water
  • 1/2 cup vegetable oil
  • 3 large eggs

Peanut Butter Swirl

  • 1 cup creamy peanut butter
  • 8 oz cream cheese, softened
  • 1/2 cup unsalted butter, melted
  • 4 cups powdered sugar
  • 1 tsp vanilla extract

Topping

  • 1 cup Reese’s Peanut Butter Cups, chopped

Instructions

  1. Preheat Oven and Prepare Pan: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish to ensure the cake doesn’t stick.
  2. Make the Cake Batter: In a large mixing bowl, combine the chocolate cake mix, water, vegetable oil, and eggs. Stir until the batter is smooth and well blended, then pour it evenly into the prepared baking dish.
  3. Prepare Peanut Butter Swirl: In a separate bowl, beat together the creamy peanut butter, softened cream cheese, melted butter, powdered sugar, and vanilla extract until the mixture is smooth and creamy, free of lumps.
  4. Swirl Mixture into Batter: Drop spoonfuls of the peanut butter mixture evenly over the chocolate cake batter. Using a knife or skewer, swirl the peanut butter mixture gently into the batter to create a marbled effect.
  5. Add Reese’s Topping: Sprinkle the chopped Reese’s Peanut Butter Cups evenly over the top of the swirled batter for extra texture and flavor.
  6. Bake the Cake: Place the baking dish in the oven and bake for 35-40 minutes, or until a toothpick inserted into the center comes out mostly clean with only a few moist crumbs attached.
  7. Cool and Serve: Allow the cake to cool slightly in the pan before slicing. Serve warm for gooey indulgence or at room temperature for easier slicing. Enjoy this rich peanut butter and chocolate dessert!

Notes

  • Use room temperature cream cheese to ensure smooth mixing.
  • For a more intense peanut butter flavor, add extra peanut butter or Reese’s cups on top.
  • The cake is best served within 2 days but can be stored in the refrigerator for up to 4 days.
  • You can substitute Reese’s Peanut Butter Cups with any peanut butter candy of your choice.
  • Letting the cake cool fully before slicing yields cleaner slices.
