  • 4 tablespoons Butter
  • 10 ounces Mini Marshmallows
  • 6 cups Captain Crunch Cereal


  • Use a large sauce pan to melt butter over medium heat.
  • When butter is almost melted add marshmallows and stir often until melted.
  • Pour cereal mixture into a lightly greased 9 x 13 inch pan. Wet fingers to spread out mixture.


  • Always use fresh cereal and marshmallows
  • Stir marshmallows often during melting process to avoid burning
  • Keep fingers wet to spread out in a 9 x 13 pan
  • My son likes to cut the recipe in half because it's easier for him to stir and manage
  • Stale cereal will make your bars hard, crunchy and difficult to cut
  • Stale or burnt marshmallows will make the recipe extra gooey and taste bad
