Eliza's Christmas Puppy Chow

Method

1. In a large bowl, combine the Rice Chex cereal and pretzel pieces.
2. Melt the peanut butter and chocolate together, either on the stovetop or in the microwave.
3. Pour the peanut butter chocolate mixture over the cereal/pretzel mixture and stir to combine.
4. Chill in the refrigerator until the mixture just barely begins to set up (about 30 minutes).
5. Remove the mixture from the refrigerator.
6. In a separate large bowl, put ½ cup powdered sugar on the bottom of the bowl. Add half of the chilled mixture, then add another ½ cup powdered sugar over the cereal and the remaining chocolate/cereal mixture.
7. Gently stir until the powdered sugar is evenly distributed, tossing to coat the cereal with powdered sugar.
8. Chill the mixture again in the refrigerator until it's set (about another 30-60 minutes).
9. Add more powdered sugar, ¼ cup at a time, until the cereal/pretzel mixture is coated.
10. Add the M&Ms and peanut butter cups and stir to combine.
11. Transfer to a serving bowl and serve. Store in an airtight container at room temperature for 5-7 days.
