Divide the tub of decorating icing evenly into 3 bowls.

To one bowl, add about ½ tsp. orange gel food coloring, and stir until well combined.

To the second bowl, add about ½ tsp. Lime green gel food coloring, and stir until well combined.

To the last bowl, add about ½ tsp. purple gel food coloring, and stir until well combined.

Lay out your fudge stripe cookies upside down onto a cutting mat.

Add each color of frosting to its own piping bag.

Take the orange frosting and pipe a generous circle onto 8 of the cookies.

Repeat with the lime green and then the purple frostings.

Place a Hershey kiss candy onto each, pressing down to form the ring of frosting around the “brim of the hat”.

Work quickly and sprinkle with Halloween sprinkles as you go, so that the sprinkles can attach before the frosting sets.
