01 - In a medium mixing bowl, beat powdered sugar, softened butter, vanilla extract, and salt until well combined and mixture appears crumbly.
02 - Add milk 1 tablespoon at a time, beating after each addition, until smooth and spreadable. Use less milk for piping consistency, more milk for a thinner glaze.
03 - Stir in almond extract if using, then add food coloring drop by drop until evenly distributed and desired color intensity is reached.
04 - Apply frosting immediately to cooled sugar cookies. Let cookies sit at room temperature for at least 1 hour to allow frosting to set completely.
