I can't tell you how long I've looked for a perfect allergy-free sugar cookie icing. A lot of them have dairy in them and then I found one without dairy and realized I had no corn syrup. So after some research on substitutions, I came up with this icing. I will use it from now on! It's the perfect consistency and tastes yummy, too!
Sugar Cookie Icing {Dairy-free, Egg-free, Vegan}
2 1/2 cups powdered sugar2 Tbsp water
1 Tbsp Smart Balance Light (or Earth Balance buttery spread - they are dairy free)
1 Tbsp Cream of Tartar (I may have used a heaping Tbsp just in case)
1/2 tsp vanilla extract
Food coloring, if desired
Combine all ingredients in a small bowl. Mix until powdered sugar is moistened. Beat at medium speed until smooth. Add additional tablespoons of water to reach desired consistency. Tint with food coloring if desired.
