  • Combine meringue powder, warm water and vanilla into a mixing bowl.
  • Using your mixer's paddle attachment, slowly add powdered sugar.
  • Add corn syrup, then continue to mix for three minutes on high. Your icing will start to turn white and have a fluffy look. DO NOT overmix.
  • This will produce a very stiff icing. To thin, slowly add small amount of water until your icing reaches the desired consistency.


- for "Flooding Consistency" icing, slowly add water until the icing will move slightly and easily spread with a scribe tool or toothpick.
 - if you'd prefer a corn-free option, you can use golden syrup (available online and at specialty stores) and organic powdered sugar that is stabilized with tapioca scratch instead of cornstarch. If you make this change, start with ⅓ cup of water instead of ½ cup.
