In a small bowl, whisk together the meringue powder and 4 tablespoons warm water. Place the mixture into a stand mixer and mix on medium-high until foamy.

Once foamy, add in the confectioner’s sugar and corn syrup and be a ton medium-high for an additional 5 minutes until stiff peaks form.

To make the frosting a consistency suitable for outlining and flooding, whisk in an additional tablespoon of room temperature water one by one until the frosting is the consistency similar to a hair gel.

You’ll know it’s correct because when you drop a spoonful of frosting from about 6 inches it will disappear back into the frosting within 10-12 seconds.

Split the frosting into 3 bowls. Color one dark green, one kelly green, and leave the other white.
