Ingredients Method Notes

Ingredients
  

For the cake
  • 1 box chocolate cake mix (15-16 oz)
  • 1 large egg
  • 1/2 cup unsalted butter, melted
For the peanut butter layer
  • 1 cup peanut butter Use creamy peanut butter for a smooth texture.
  • 1 cup powdered sugar Can be reduced for less sweetness.
  • 1/2 cup chocolate chips Alternatively, use peanut butter chips.
Other ingredients
  • 1 cup milk For a lighter version, use low-fat milk.

Method
 

Preparation
  1. Preheat the oven to 350°F (175°C). Grease a 9x13 inch baking pan.
  2. In a mixing bowl, combine the chocolate cake mix, egg, and melted butter. Mix until well combined. Spread the batter evenly in the prepared pan.
  3. In another bowl, mix the peanut butter and powdered sugar together until creamy. Drop spoonfuls of the peanut butter mixture over the chocolate cake batter.
  4. Pour the milk over the top and swirl gently with a knife to create a marbled effect.
  5. Sprinkle chocolate chips on top of the batter.
Baking
  1. Bake for 30-35 minutes, or until the edges are set but the center is slightly gooey.
  2. Let cool slightly before serving. Enjoy warm or at room temperature!

Notes

Use creamy peanut butter for smooth pockets of sweetness; crunchy works too if you like texture. Don't overbake — the heart of this cake is a slightly gooey center. If your cake is browning too fast on top, tent with foil for the last 10 minutes. For a richer peanut flavor, stir a teaspoon of vanilla into the peanut butter mixture.
