• 3 cups confectioners' sugar
  • 1/2 teaspoon lemon juice
  • 2 tablespoons powered egg whites
  • 6 tablespoons warm water
  • Pink food coloring
  • Green food coloring
  • Blue food coloring
  • Yellow food coloring
  • You will also need:
  • Large resealable plastic bags
  • Pastry bag fitted with fine tip
  1. Using an electric mixer set on low speed, mix powdered egg whites and warm water until all the water is incorporated, about 2 minutes.
  2. Add the sugar and the lemon juice; mix on high speed until icing is smooth, about 5 minutes (at this point you can just leave the icing white or you may tint some of the icing). Divide icing evenly among 5 bowls. Set aside 1 bowl of icing.
  3. Tint remaining bowls of icing pink, green, blue, and yellow; spoon each color into large resealable plastic bags; snip off one corner for piping.
  4. Using tinted icing, pipe an outline onto each cookie then fill with base color; spread icing evenly. Let icing set until dry.
  5. Place reserved white icing in a pastry bag fitted with a fine tip. Pipe designs on cookies as desired. Let icing set until dry
