Make these delicious Shamrock Rice Krispies.


Make these cute Green Shamrock Rice Krispies for St. Patrick's Day.


  • 3 TBS Butter
  • 10 oz bag Marshmallows or 4 cups of Mini Marshmallows
  • Food Color: We like the Wilton gels below, they are vibrant and a little goes a long way. It also has a lot of variety so you don't have to combine colors to get teal, purple, brown and black.
  • Frosting (tube) or you can make icing like our Cookie Icing Recipe

Other Items

  • Wooden Spoon to stir
  • Parchment Paper or Pam cooking spray
  • Large Shamrock Cookie Cutter (you need a large sized cookie cutter to be able to have a clear shape. We like the Wilton one listed below because it is easy to press into the rice krispies because of the cushioned grip and the deep sides.


  • Prepare Rice Krispies as directed above (same recipe as on the box)
  • Melt margarine or butter in large saucepan over low heat. Add marshmallows and stir until completely melted.
  • Add a few drops of green food color. Stir until well blended, add a few more drops if you would like a darker color.
  • Add Rice Krispies cereal. Stir until well coated.
  • On a cookie sheet sprayed with Pam, shape mixture into a flat shape about 1/2 inch high. (test temperature when kids are shaping this.)
  • Press cookie cutter into the Rice Krispies and pull away excess, then lift up the cookie cutter for best results. Young children can help at this point cut the Shamrocks as mixture will have cooled sufficiently after shaping. This cutter is perfect for young kids.
  • Reform into a flat surface with the excess and repeat with the cookie cutter.
  • Decorate with frosting.

Tips and Suggestion

  • Note Let Rice Krispies cool for about 30 seconds to one minute before handling. If you wait too long it will harden and be difficult to shape.
  • Spray hands with Pam or put a little butter on your fingers when shaping the Rice Krispies to keep from sticking to fingers.
  • We used a Wilton shamrock cookie cutter (see below). It will make about a dozen shamrock krispies.
