- 4 cups confectioner's sugar, plus more for thickening
- 3 tablespoons meringue powder
- ¼ cup water, plus more for thinning
- Sift the confectioner's sugar and meringue powder into a medium-sized bowl. Add ¼ cup water, and mix using an electric mixer with a whisk attachment, until smooth.
- For simple decorations, the icing should flow off the beater, and settle into a smooth state in the icing bowl within 5 seconds.
- Make the thicker icing by adding 1 additional tablespoon of powdered sugar at a time. Make the icing thinner by adding 1 additional teaspoon of water, until reaching the desired consistency.
- Color, if desired, and decorate.
