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