Ingredients:
- 4 cups (480 g) sifted Confectioners’ Sugar (Icing Sugar)
- 3 Tbsp (27 g) Meringue Powder
- 6 to 8 Tbsp (90 to 120 ml) Warm Water
- 1 tsp (5 ml) Light Corn Syrup (Golden Syrup)
- 1 tsp (5 ml) Pure Vanilla Extract
- 1/2 tsp (2.5 ml) Fresh Lemon Juice
Instructions:
- Sift the confectioners’ sugar and meringue powder together into the bowl of your electric mixer to prevent lumps.
- Add the minimum amount of warm water (6 Tbsp / 90 ml) to the dry ingredients, along with the corn syrup, vanilla, and lemon juice.
- Start the mixer on the lowest speed to combine the ingredients gently until wet and clumpy. Scrape down the bowl.
- Gradually increase the speed to Medium-High and beat the mixture for 5 to 7 minutes until the frosting is thick, very glossy, and holds stiff peaks (Piping Consistency).
- Divide the frosting into smaller bowls for colouring and keep any unused frosting tightly covered with cling film pressed directly against the surface.
- To achieve Flooding Consistency: Add water to the colored frosting, one drop at a time, until a line drawn through the mix with a spoon self-levels and disappears completely within 8 to 10 seconds.
- Transfer piping consistency and flooding consistency to separate piping bags. Decorate cookies by outlining first, then filling the center with the thinner consistency.
- Allow decorated cookies to dry, uncovered, for at least 60 minutes, and ideally overnight (8-12 hours), until the Sugar Cookie Frosting is completely hard to the touch.
