Ingredients
  

Royal Icing Base
  • 4 cups Powdered Sugar sifted
  • 3 tbsp Meringue Powder for stability
  • 6 tbsp Water adjust gradually
  • 1 tsp Vanilla Extract optional
Optional Additions
  • 1 tsp Corn Syrup optional for smoother finish
  • as needed Gel Food Coloring optional

Equipment

  • Mixing Bowl
  • Hand Mixer
  • Measuring Cups
  • Measuring Spoons
  • Rubber Spatula
  • Piping Bags
  • Cooling Rack
  • Fan
  • Freezer
  • Tray
  • Cookie Scoop
  • Baking Sheet
  • Oven

Method
 

  1. Combine powdered sugar and meringue powder in a mixing bowl until fully blended.
  2. Add water gradually and mix until the icing becomes smooth, glossy, and easy to pipe.
  3. Adjust consistency carefully. Slightly thinner icing may require longer drying time.
  4. Decorate cooled cookies and spread icing evenly to avoid thick areas that dry slowly.
  5. Place cookies on a cooling rack and encourage airflow with a fan set on low speed.
  6. Allow layers to dry completely before adding details, stacking, packaging, or serving.

Notes

For a softer finish, increase liquid slightly. For firmer details and quicker drying, reduce liquid a little. Freeze decorated cookies only after icing fully hardens and package carefully to prevent condensation. Handle layered decorations gently. Customize flavor with vanilla, citrus, almond, or peppermint extracts. Store cookies in airtight containers away from moisture.
