Toll House Snack Mix

My friend, Michelle, made this snack mix for my baby shower for Caitlyn. It is delicious and easy to make! Be careful though...it is VERY addictive!

4 cups rice Chex (or choice of cereal)
1 cup nuts
1 cup (about 20) caramels, unwrapped and coarsely chopped
1 (12-oz) bag milk/semi-sweet/butterscotch chips

Coat a 9x13 pan with nonstick cooking spray. Combine first 3 ingredients in large bowl. Microwave chips for 1 minute, stir, and microwave additional 10-20 second intervals until melted. Stir until smooth. Pour over cereal mixture to coat evenly. Spread into prepared pan and cool 45 minutes, or until firm. Break into bite-size pieces.
