Ingredients:
- 4 cups (450g / 1 lb) powdered sugar, sifted
- 3 tablespoons (45 ml) meringue powder
- 6 tablespoons (90ml) lukewarm water
Instructions:
- In the bowl of a stand mixer, combine the sifted powdered sugar and meringue powder.
- Gradually add the lukewarm water to the dry ingredients, mixing on low speed until combined.
- Increase the mixer speed to medium-high and beat for 5-7 minutes, or until the icing is glossy and forms stiff peaks.
- Adjust consistency: For outlining icing, add water, one teaspoon at a time, until thick enough to hold shape. For flooding icing, add water until it flows easily and smooths in 10-15 seconds.
- Divide the icing into smaller bowls and add food coloring gels, one drop at a time, until you achieve your desired shades.
- Fill piping bags with the icing. If using zip-top bags, snip a small corner off.
- Pipe and decorate your cookies as desired.
- Allow the decorated cookies to dry completely at room temperature, uncovered, for at least 6-8 hours, or preferably overnight.
