INSTRUCTIONS
- 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 9×13 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 powdered sugar. Cut and serve!
