Ingredients
  

Cookie Base

  • 12 pieces Sandies cookies (or flat shortbread rounds) Buy the classic Sandies or any firm shortbread cookie with a flat top for best adhesion.

Toppings

  • 2 cups green candy melts Choose a high-quality brand that melts smoothly.
  • 12 pieces standard-sized marshmallows Use fresh, pillowy marshmallows for the best texture.
  • Black fondant Creates the hat band details.
  • Yellow fondant Used for the buckle details.
  • White fondant (if coloring your own) Use gel food coloring to avoid weakening the fondant.
  • 1 drop vegetable oil To restore shine if coating becomes thick.
  • Optional green sanding sugar or themed sprinkles For a sparkling finish.

Instructions
 

Preparation

  • Melt the green candy melts in a microwave-safe bowl. Heat for 30 seconds, stir, then continue heating in 15-second bursts until smooth.
  • Dip each Sandies cookie into the melted green coating, coating the top completely, then set aside to harden.
  • Coat each marshmallow in the green candy and place it on the cookie.
  • If needed, color white fondant and cut strips for hat bands. Wrap them around the marshmallow bases.
  • Roll yellow fondant into buckle shapes and attach to the center of each black band.
  • Add optional sanding sugar or sprinkles before the coating fully hardens.
  • Chill cookies for 10–15 minutes to set the coating.

Storage

  • Store finished Leprechaun Hat Cookies in an airtight container lined with parchment paper in the fridge for up to 5 days.
  • Freeze cookies between parchment in a freezer-safe container for up to 1 month; thaw in the refrigerator before serving.

Notes

Keep candy melts warm but never overheated. Use silicone utensils for easier cleanup.
