Pour the rice Chex cereal into a medium bowl.

In a small microwave safe bowl add the white chocolate chips and microwave for 30 seconds at a time, stirring well in between, until melted and smooth.

Pour the melted white chocolate over the rice Chex cereal and toss until it is coated.

Pour the coated cereal onto a parchment paper lined baking sheet and sprinkle with Christmas sprinkles.

In a large microwave safe bowl add corn Chex cereal, wheat Chex cereal, almonds, pecans, and mini pretzels.

Melt butter and pour over the Chex mix tossing it to coat.

Combine sugar and cinnamon and pour over the buttered mix tossing so everything is coated evenly.

Place bowl in microwave and cook on high for 1 minute, stopping to stir it again before microwaving it for 1 minute more.

Remove from microwave and spread the Chex Mix out on a lined baking sheet pan to cool.

Once both the white chocolate and cinnamon sugar Chex mix has cooled completely add them both to a large bowl along with red & green Christmas M&Ms.

Store in an airtight container until ready to serve.
