  • 7 cups Rice Chex cereal, (start with 5 cups and check consistency)
  • 1 cup semi-sweet chocolate chips
  • 1 cup (258 g) creamy peanut butter
  • ¼  cup  (½ stick / 57 g) unsalted butter, can use salted
  • 1 bag (10 ounces) mini marshmallows
  • ¼ cup (31 g) confectioners' sugar


  • In a large mixing bowl, add the Chex cereal and set aside.
  • In a separate medium microwave-safe bowl, combine the chocolate chips, peanut butter, and butter. Microwave in 30-second intervals, stirring until melted.
  • Add in the mini marshmallows, stir to coat and return to the microwave, cooking again in 30-second intervals until the marshmallows start to puff and melt. The mixture should be thick and creamy.
  • Pour the marshmallow mixture over the Chex cereal and stir to coat. (Make sure to stir as much as you need in order to generously coat all of the cereal.)
  • Transfer the cereal mixture to a 9x13 inch greased baking pan and press it firmly into the pan. Set in the refrigerator to chill for 10-15 minutes.
  • Lightly coat the top of the bars with confectioners' sugar. Cut and serve!
