A festive twist on a classic treat for my youth group buddies.
1/4 cup butter or margarine
4 cups mini marshmallows
5 cups crisp rice cereal
1 bag Christmas M&M's
Melt butter in a large saucepan over low heat. Add marshmallows and stir until melted and mixed. Heat 2 more minutes, stirring constantly. Remove from heat. Add cereal and M&M's. Mix thoroughly. Using a buttered spatula, press mixture firmly into a greased 13 x 9 inch pan. Allow treats to cool before slicing.
