Melt butter in saucepan over low heat. Add marshmallows and stir until completely melted. Remove from heat and stir in crispy rice cereal. On the wax paper, spread mixture into a rectangular layer about 1-2 1/2" thick. Unwrap and chop the candy bars, then sprinkle them onto the mixture. Spray hands with cooking spray. Then roll the entire mixture into a cylinder. Decorate the top of the roll with red and green M&M candies or small red cinnamon candies. Slice and serve!
