In a large mixing bowl, add the rice Chex cereal and set aside.
In a medium sized microwave bowl, add the chocolate chips, peanut butter and butter. Microwave for 1 minute and stir.
Microwave for an additional 30 seconds to ensure the mixture is smooth and creamy.
Add the vanilla and stir to incorporate.
Pour mixture over the cereal and stir or mix with hands to evenly coat. (It gets rather sticky so it helps to spray your hands with Pam spray).
Transfer the cereal into a large Ziploc bag (one gallon or larger).
Add the powdered sugar to the cereal mixture. Seal the bag and gently shake until all of the cereal pieces are evenly coated with the powdered sugar.
Line a baking sheet with wax paper.
Carefully, pour out the cereal onto the baking sheet and spread out to cool.
Once cooled, transfer the mixture to a serving bowl.
Add the red and white M&M's, red sugar crystals and Kit Kat pieces.
ENJOY!!
