Muddy Buddies Chex Mix

Just looking at this makes me want to go and make some!!!!

4 1/2 cups Rice Chex Cereal

4 1/2 cups Corn Chex Cereal

1 cup chocolate chips

1/2 cup peanut butter

1/4 cup butter

1 teaspoon vanilla

1 1/2 -2 1/2 cups powder sugar

Place cereal in a large bowl; set aside. In a microwave safe bowl, combine chocolate, peanut butter, and butter. Microwave 1 minute; stir. Microwave 30 seconds more; stir. Continue in 15 second intervals until chips are melted. Add vanilla. Pour over cereal and stir until well coated. Transfer to two gallon zip-lock bags. Divide the sugar between the two bags. Seal bags tightly and shake and toss until well coated, adding more sugar as needed until everything is coated nicely. Pour onto wax paper to cool. Once completely cooled, store in an airtight container.
