Equipment

  • Stand mixer or hand mixer
  • Large mixing bowl
  • Piping bags
  • Piping tips (#1, #2, #3 recommended)
  • Scribe tool or toothpick
  • Small bowls for coloring
  • Gel food coloring
  • Airtight container for storage

Method
 

Step 1: Combine Dry Ingredients
  1. In your mixing bowl, combine:
  2. powdered sugar
  3. meringue powder
  4. Sift for best texture.
Step 2: Whip the Icing
  1. Add 6 tablespoons warm water to the dry mixture.
  2. Beat on low until combined, then increase to medium-high speed.
  3. Mix 3–5 minutes until the icing is:
  4. thick
  5. glossy
  6. smooth
  7. forming soft peaks
  8. Add water ½ teaspoon at a time if too thick.
  9. Add more powdered sugar if too thin.
Step 3: Add Flavor & Shine
  1. Mix in:
  2. vanilla or almond extract
  3. optional corn syrup
  4. Corn syrup makes the finish smoother and slightly softer, preventing an overly hard crunch.
Step 4: Set Your Consistencies
  1. Royal icing needs different consistencies depending on the design:
For Outlining (Thicker):
  1. Aim for “toothpaste consistency.”
  2. Creates crisp borders.
  3. For Flooding (Thinner):
  4. Add tiny amounts of water until icing flows like honey.
  5. A line drawn through the icing should disappear in 8–10 seconds.
For Detail Work:
  1. Slightly thicker than flood, thinner than outline.
  2. Perfect for lines, swirls, dots.
  3. Divide icing into bowls and adjust consistencies as needed.
Step 5: Color the Icing
  1. Use gel food coloring for vibrant color without thinning the icing.
  2. A little goes a long way — start small and build color gradually.
  3. Cover each bowl with plastic wrap touching the surface to prevent crusting.
Step 6: Decorate Your Cookies
  1. Fill piping bags with desired colors.
For clean designs:
  1. Pipe outline
  2. Flood inside
  3. Use a scribe/tool to smooth
  4. Add wet-on-wet designs (hearts, polka dots, marbling)
  5. Add layering details after 20–30 minutes of drying
  6. Let cookies dry 6–8 hours or overnight for stacking.
