Egg White Royal Icing
0 In a large bowl using a handheld electric mixer, whip egg whites on medium high until soft peaks form. 
1 Add vanilla, then mix in 1 cup of a sugar at a time while continuing on medium high speed.
2 Scrape bottom and side of bowl with rubber spatula to incorporate all powdered sugar stuck on sides.
3 Whip for 2-3 minutes until thick and glossy.

Meringue Powder Royal Icing
7 In a large bowl using a handheld electric mixer, whip sugar, meringue powder, vanilla, and 8 tablespoons of the water together on medium high until combined and thick. (3-4 minutes)
8 When you lift the whisk from the bowl, icing should be glossy and softly fall back into the bowl without completely falling off whisk. If it seems to thick add another Tbsp of water and mix again. On the other hand if its too thin, slowly add more powdered sugar until desired consistency is reached.
9 Transfer to piping bag with desired tip and decorate. Set frosted cookies on counter to set for 1-2 hrs before stacking.
