1/2 cup butter
1 cup Nutella (this is a just a whole small container)
1 pkg dark or semi-sweet chocolate chips (milk chocolate is too sweet)
1 pkg white chocolate chips
1 box Rice Chex (12 oz box)
Melt butter and chocolate chips in medium saucepan. Take off heat and add Nutella. Pour over Rice Chex in a large mixing bowl. With CLEAN hands, mix it until the chex is coated enough for the powdered sugar.
When coated, put it in a large ziploc bag (you may have to do two different batches) with the powdered sugar and shake it until evenly coated. Pour in bowl and enjoy.
