Ingredients

Scale

Chocolate Cake Batter

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

Peanut Butter Mixture

  • 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 the cake from sticking.
  2. Make cake batter: In a large mixing bowl, combine the chocolate cake mix, water, vegetable oil, and eggs. Stir until the batter is smooth and all ingredients are well incorporated.
  3. Prepare peanut butter mixture: In a separate bowl, blend the creamy peanut butter, softened cream cheese, melted butter, powdered sugar, and vanilla extract until the mixture is smooth and free of lumps.
  4. Assemble cake: Pour the chocolate cake batter evenly into the prepared baking dish. Then, drop spoonfuls of the peanut butter mixture over the batter. Use a knife or skewer to gently swirl the peanut butter mixture through the chocolate batter, creating a marbled effect.
  5. Add toppings: Evenly sprinkle the chopped Reese’s Peanut Butter Cups over the top of the swirled batter.
  6. Bake: Place the baking dish in the preheated oven and bake for 35 to 40 minutes. The cake is done when a toothpick inserted into the center comes out mostly clean with a few moist crumbs.
  7. Cool and serve: Let the cake cool slightly before slicing. Serve warm for a gooey texture or at room temperature for a firmer slice.

Notes

  • For best results, use room temperature cream cheese and butter to achieve a smooth peanut butter mixture.
  • This cake can be stored covered at room temperature for up to 2 days or refrigerated for up to 5 days.
  • To enhance the peanut butter flavor, use natural creamy peanut butter without added sugars or oils.
  • To serve chilled, refrigerate the cake and enjoy it as a rich peanut butter chocolate dessert bar.
  • Feel free to replace Reese’s Peanut Butter Cups with your favorite peanut butter candy or chocolate chips.
