  • Using the standing mixer, combine the egg whites, cream of tarter, powder sugar and vanilla and mix on medium speed until stiff peaks form
  • Split the icing into 4 bowls
  • In one bowl, add a few drops of the mint green gel coloring to get a light shade of green
  • In the second bowl, add a few drops of the leaf green gel food coloring to get a semi dark shade of green
  • In the third bowl, add a few drops of the purple to get a light shade of purple
  • In the fourth bowl, add a few drops of the purple to get a dark shade of purple.
  • Scoop some icing into the piping bags and set aside
  • Add about 2-3 tbsp of cold water to the bowl and mix until combined. This will thin out the icing so that it will be easier to flat ice the cookies.
  • Pour thinned icing into the squeeze bottles and set aside

Decorating directions:
