Melt the Chocolate and Peanut Butter

1. Melt the Peanut Butter and Chocolate: In a medium saucepan, melt the peanut butter, semi-sweet chocolate chips, and unsalted butter over low heat, stirring frequently until smooth. Once melted, remove the saucepan from heat and stir in the vanilla extract.

Coat the Cereal

1. Prepare the Cereal: In a large mixing bowl, pour in the gluten-free rice Chex cereal.
2. Mix Together: Pour the peanut butter and chocolate mixture over the cereal. Gently toss to coat each piece evenly, making sure all the cereal is covered with the chocolate-peanut butter goodness.

Coat with Powdered Sugar

1. Add Powdered Sugar: Transfer the coated cereal into a large resealable plastic bag or another large bowl. Add the powdered sugar and shake or stir until the cereal is fully coated with the sugar.

Chill the Chow

1. Let it Set: Spread the coated cereal onto a baking sheet or large tray to cool and set for about 10 minutes. This allows the coating to harden, giving your chow that delicious crunchy texture.

Garnish and Serve

1. Add Festive Touches: If desired, sprinkle M&Ms, holiday sprinkles, or small candy pieces over the top of the chow for an extra pop of color and sweetness.
2. Serve: Once set, serve the Reindeer Chow in a festive bowl or package it up in cute gift bags for friends and family.
