Meal Prep

Make Icing Ahead – Mix the icing ingredients and cover with an airtight seal (either plastic wrap or a lid).
Make & Color Icing Ahead – Mix the icing ingredients and divide between 4 smaller bowls (or more). Add the food coloring sparingly (adding too much will make the icing runny) and cover each bowl with plastic wrap or a lid.

Lose Weight By Eating
This Low Calorie Royal Icing is ZERO CALORIES thanks to my favorite all-natural zero calorie powdered sugar! You can swap it out for your favorite powdered sugar or powdered sugar substitute.
This makes enough frosting to cover 30 cookies, and if you add too much water, don't worry… Just add more powdered sugar 1/2 tablespoon at at time.
Special Tip: Be sure to see the notes below, I included more flavors like Peppermint, Strawberry, and Lemon Icing!
