How to Make Chocolate Peanut Butter Bars

  1. Preheat oven to 350°F (175°C).
  2. In a large bowl, combine 1 box (15.25 oz) chocolate cake mix, ¾ cup water, ½ cup (1 stick) unsalted butter, melted, and 2 large eggs. Mix until well combined.
  3. Grease a 15 x 10 inch baking pan. Press the chocolate mixture evenly into the prepared pan.
  4. Bake for 14 minutes.
  5. Remove from oven and immediately sprinkle evenly with 1 cup mini marshmallows.
  6. Return to oven and bake for 2 more minutes.
  7. Remove from oven and let cool completely.
  8. While the chocolate layer cools, prepare the peanut butter topping. In a medium saucepan, combine 1 cup peanut butter chips, ¼ cup light corn syrup, 2 tablespoons unsalted butter, and 1 teaspoon vanilla extract.
  9. Cook over low heat, stirring constantly, until the chips are melted and the mixture is smooth.
  10. Remove from heat and stir in 1 cup Rice Krispies cereal and ½ cup salted peanuts.
  11. Pour the peanut butter mixture evenly over the cooled marshmallow layer.
  12. Refrigerate for at least 30 minutes before cutting into bars. Enjoy!
