Equipment

  • Medium sized bowl
  • whisk
  • Piping Bags

Ingredients

  • 2 cups powdered sugar sifted
  • 2-3 tablespoons milk (adjusted for desired consistency)
  • 1 tablespoon light corn syrup
  • 1/2 teaspoon vanilla extract
  • Food coloring (optional)

Instructions

  • In a medium bowl, whisk together the powdered sugar, 2 tablespoons of milk, corn syrup, and vanilla extract until smooth.
  • Add more milk, 1 teaspoon at a time, until the icing reaches your desired consistency. For outlining cookies, use a slightly thicker consistency. For flooding cookies, make the icing thinner.
  • Divide the icing into separate bowls if using multiple colors. Add food coloring to each bowl and stir until the color is evenly distributed.
  • Transfer the icing to piping bags or squeeze bottles for decorating. Alternatively, use a spoon or knife to spread the icing onto cookies.
  • Allow the icing to set for 2-3 hours at room temperature, or until fully dry. Store any unused icing in an airtight container in the refrigerator for up to 3 days.

Notes

  • Cool the cookies first: Let the sugar cookies fully cool to room temperature before applying the icing. If the cookies are warm, the icing will slip right off.
  • Let them set before stacking: When the decorating is complete, let the cookies sit out for 2-3 hours at room temperature to fully set. This will keep the icing from smudging.
  • Adjust the consistency: If the icing starts to thicken while it sits, add a few drops of milk to the mixture to loose it up again.
