Equipment

  • Bowls
  • Toothpicks
  • Piping Bags
  • Squeeze Bottles
  • Scribe

Ingredients
  

Royal Icing

  • 4 cups Prepared Royal Icing
  • Gel Food Coloring Red, Green, Blue, Yellow, Black, White (or preferred palette)
  • Water as needed, for consistency adjustment
  • Powdered Sugar as needed, for consistency adjustment

Instructions
 

Preparation

  • Start with prepared royal icing and divide it into separate bowls for each color, including one for plain white.
  • Add a tiny amount of gel food coloring to each bowl using a toothpick and mix thoroughly until the desired shade is achieved, building up deeper hues gradually.
  • For outlining, add water drop by drop to a portion of each colored icing until it holds its shape when piped.
  • For flooding, slowly add water to the remaining colored icing until a line drawn on the surface disappears within 10-15 seconds.

Decorating the Cookies

  • Fill separate piping bags or squeeze bottles with each color of icing, ensuring both outline and flooding consistencies are ready.
  • Pipe a border around the edges of cooled sugar cookies with the stiffer outline icing and let it dry for 10-15 minutes.
  • Fill the outlined areas with the thinner flooding icing, spreading it to the edges and popping air bubbles with a toothpick.
  • Allow the flooded cookies to dry completely for 6-8 hours or overnight before adding further details to prevent color bleeding.
  • Once the base layer is dry, use the remaining colors to pipe accents, patterns, or intricate designs onto the cookies.
  • Let the fully decorated cookies dry completely for another 12-24 hours before stacking, packaging, or serving.

Notes

Gel food coloring is highly concentrated, so start with a tiny amount and add more gradually to achieve the desired shade. Ensure each layer of icing is completely dry before adding the next to prevent colors from bleeding together.
