Easy Decorated Snowman Cookies

To make icing, combine 2 cups powdered sugar, 2-3 tablespoons water (luke-warm), ⅛ teaspoon salt, and 1  teaspoon vanilla extract in a medium-sized bowl. Mix until smooth.

Add more water or powdered sugar until it reaches your desired consistency. If using a piping bag, about [adjustable]2[/adjustable] tablespoons of water is best (you want the icing to be about the consistency of pancake batter). If dipping or drizzling the icing, [adjustable]3[/adjustable] tablespoons of water will likely be needed. See notes below for storing and freezing notes.

To decorate, immediate press M&M's into wet icing. 
Have an adult cut [adjustable]12[/adjustable] brown mini M&M’s in half to create the smiling mouth. To decorate the snowman faces, press on 2 brown M&M’s for the eyes, 1 sideways orange M&M for the carrot nose, 2 red M&M’s for the rosy cheeks, and then finish it off with the half brown M&M. If desired, you can add 2 green M&M’s to a blank cookie to create a button body.
For an added touch, once faces have been added, sprinkle on a small amount of white sanding sugar.
