Cake Ingredients

  • 1 box 15.25 oz chocolate cake mix Any brand
  • 1 cup water
  • ½ cup vegetable oil
  • 3 large eggs
  • 1 cup creamy or crunchy peanut butter Your preference
  • 8 oz cream cheese, softened Full-fat recommended
  • ½ cup powdered sugar
  • 1 teaspoon vanilla extract
  • 1 cup chocolate chips Semi-sweet or milk chocolate
  • ½ cup chopped pecans or walnuts Optional

Instructions
 

Preparation

  • Start by gathering all your ingredients and equipment. Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan.
  • In a large mixing bowl, combine the chocolate cake mix, water, vegetable oil, and eggs. Mix according to package instructions until smooth, about 2 minutes.
  • Pour half of the cake batter into the prepared baking pan evenly.
  • In a separate bowl, beat the softened cream cheese until smooth. Add in the powdered sugar, peanut butter, and vanilla extract, mixing until creamy.
  • Drop spoonfuls of the cream cheese mixture evenly over the chocolate cake batter. Swirl with a knife for a marbled effect.
  • Pour the remaining cake batter over the cream cheese layer and sprinkle with chocolate chips and nuts.
  • Bake for 35–40 minutes or until the surface is cracked and a toothpick comes out mostly clean.
  • Let the cake cool in the pan for 10–15 minutes before serving.

Notes

Best served with whipped cream, vanilla ice cream, or a drizzle of chocolate sauce. This cake can be stored in the fridge for up to 5 days or frozen for 3 months.
