With just three ingredients, this royal icing is easy to whip up and even easier to decorate with. Use it for your sugar cookies, gingerbread houses and more.
3 egg whites
1/4 tsp white vinegar
5 cups icing sugar, sifted
Beat egg whites and vinegar in a large bowl, using an electric mixer on medium, until foamy. Gradually beat in icing sugar on low until combined. Increase speed to high and beat until icing is dense and thick but still foamy, 3 to 7 min.
Beat in 2 to 4 tbsp cold water to thin icing out to desired consistency. Transfer to a piping bag fitted with a very small plain tip to decorate cool cookies.
