Ingredients:
- 4 cups (480g) powdered sugar, sifted
- 3 tbsp (45ml) warm water
- 1 tbsp (15ml) light corn syrup
- 1 tsp (5ml) pure vanilla extract
- 1 large egg white (30g)
Instructions:
- Combine the egg white, corn syrup, and vanilla extract in a mixer bowl. Beat on low for 1 minute until combined. Note: This creates the liquid base
- Slowly add the sifted powdered sugar. Mix on the lowest speed until the sugar is incorporated, then increase to medium for 2 minutes until the mixture is smooth and cloud like.
- Add warm water, one teaspoon at a time, while mixing on low. Mix until the icing holds a stiff peak for piping.
- For flooding, continue adding water one teaspoon at a time. Mix until a line drawn through the icing disappears in 15 seconds.
- Divide the icing into small bowls. Add gel food coloring and stir by hand slowly to avoid adding air bubbles.
- Pipe the outlines first and let them set for 20 minutes before you start flooding.
- Flood the centers of the cookies. Use a scribe tool to smooth edges until the surface is perfectly flat.
- Let the cookies rest for 9 hours 10 mins to ensure they are completely dry.
