Ingredients

Scale

Chocolate Cake Base

  • 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 and Prepare Pan: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish to prevent sticking.
  2. Mix Cake Batter: In a large bowl, combine the chocolate cake mix, water, vegetable oil, and eggs. Stir until all ingredients are well incorporated and the batter is smooth. Pour this batter evenly into the prepared baking dish.
  3. Prepare Peanut Butter Mixture: In a separate bowl, blend the creamy peanut butter, softened cream cheese, melted butter, powdered sugar, and vanilla extract. Mix thoroughly until the mixture is smooth and creamy with no lumps.
  4. Swirl Mixture into Batter: Drop spoonfuls of the peanut butter mixture across the surface of the chocolate cake batter. Using a knife, gently swirl the peanut butter mixture into the batter to create a marbled effect.
  5. Add Topping: Evenly sprinkle the chopped Reese’s Peanut Butter Cups over the swirled batter to add texture and extra peanut butter flavor.
  6. Bake: Place the baking dish in the preheated oven and bake for 35 to 40 minutes, or until a toothpick inserted into the center comes out mostly clean with just a few moist crumbs attached.
  7. Cool and Serve: Remove the cake from the oven and allow it to cool slightly in the pan before serving. This cake is delicious when enjoyed warm or at room temperature.

Notes

  • For best cream cheese consistency, ensure it is softened to room temperature before mixing.
  • You can substitute creamy peanut butter with natural peanut butter, but texture may vary.
  • Allow the cake to cool a bit before slicing to help it hold its shape.
  • Store leftovers in an airtight container in the refrigerator for up to 4 days.
  • To intensify the peanut butter flavor, add a few extra chopped peanut butter cups on top just before serving.
