Use this recipe to decorate our Sugar-Coated Marshmallow Bunnies and Chicks, Chocolate-Coated Marshmallow Chicks, and Flat Marshmallow Shapes. While not in use, the tip of the icing bag should be wrapped in a damp paper towel -- icing hardens quickly when exposed to air.


  • ½ pound confectioners' sugar (2 cups)

  • 2 ½ tablespoons meringue powder

  • ¼ cup water

  • Black or dark-brown gel food coloring


  1. In the bowl of an electric mixer fitted with the paddle attachment, combine confectioners' sugar and meringue powder with scant 1/4 cup water on low speed. Mix until fluffy yet dense, 10 to 15 minutes.

  2. Color the icing as needed starting with a small amount of gel food coloring.Transfer to a small pastry bag fitted with a 1/32-inch pastry tip (#1 Ateco).

  3. If making marshmallow treats, pipe faces as desired, or pipe eyes on both sides of coated chicks and two eyes and a nose on bunnies. Pipe one eye on flat bunnies and chicks. Store the royal icing in an airtight container up to a week, and stir before using.
