Prep: Butter a 9x13 inch baking dish or spray with cooking spray. Set aside.
Melt: In a medium saucepan, melt butter and marshmallows over medium-low heat. Mix until marshmallows are melted and you have a smooth mixture. Tip: Keep the temperature low and stir often so the marshmallows don't burn.
Mix: Pour marshmallow mixture into a large mixing bowl and add the M&Ms. Then, add Rice Krispie cereal. Mix with a silicone spatula (or wooden spoon) until all of the cereal is well-coated.
Transfer: Transfer mixture into prepared 9x13 baking dish. Spread in an even layer. Tip: use a fork or spatula coated with a little butter if the mixture is too sticky to spread easily.
Sprinkle (optional): Sprinkle on additional M&M's over the top, if you like.
Cool (optional): Set aside or refrigerate for about an hour. The treats will be easier to cut into squares when cool. When cool, cut into squares and enjoy.
