  • ¼ cup Butter Unsalted
  • 6 cups Marshmallows Mini
  • 8 cups Cereal Fruit Loops


  1. In a deep mixing bowl, add the butter and marshmallows.
  2. Heat in the microwave until everything is melted. Be sure to remove the bowl from the microwave every 30 seconds and give everything a quick stir.
  3. Once you have a smooth marshmallow mixture, dump the cereal into the bowl and mix everything.
  4. Now, spread this fruit loops mixture on a cookie tray that’s been sprayed generously with oil.
  5. Chill in the refrigerator for an hour and then cut into bars or shards like I did. Enjoy!
