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