  • Author: Lana
  • Total Time: 10 minutes
  • Yield: 24 servings 1x

Description

This classic sugar cookie icing recipe creates a smooth, glossy coating that hardens perfectly for beautifully decorated cookies. Made with simple pantry ingredients like powdered sugar, milk or water, corn syrup, and vanilla extract, this icing is easy to prepare and customize with gel food coloring. It’s ideal for piping detailed outlines and flooding cookie surfaces, drying to a firm finish that allows cookies to be stacked or wrapped without smudging.


Ingredients

Scale

Dry Ingredients

  • 2 cups powdered sugar, sifted

Wet Ingredients

  • 2 to 3 tablespoons milk or water
  • 1 tablespoon light corn syrup
  • 1/2 teaspoon vanilla extract

Optional

  • Gel food coloring, as desired

Instructions

  1. Sift the powdered sugar: Sift 2 cups of powdered sugar into a medium bowl to remove any clumps, ensuring a smooth and lump-free icing base.
  2. Add liquid ingredients and mix: Add 2 tablespoons of milk or water, 1 tablespoon of light corn syrup, and 1/2 teaspoon of vanilla extract to the sifted sugar. Whisk the mixture thoroughly until it becomes smooth and glossy.
  3. Adjust icing consistency: Check the thickness of the icing and add more milk or powdered sugar if needed to reach the desired consistency. Thicker icing is better for detailed piping while thinner is ideal for flooding cookie surfaces.
  4. Color your icing: Divide the icing into separate bowls if using multiple colors and tint each portion with gel food coloring to achieve vibrant hues.
  5. Decorate your cookies: Use piping bags or spoons to apply the icing to cookies. Use the thicker icing for outlining shapes and the thinner icing for flooding the areas inside the outlines.
  6. Allow icing to dry: Let the decorated cookies dry completely at room temperature for 6 to 12 hours. This hardens the icing so the cookies become stackable without smudging.
  7. Store leftover icing: Place any leftover icing into an airtight container and refrigerate for up to one week to preserve freshness.
  8. Rehydrate before reuse: When ready to use leftover icing, stir it well and add a little milk or water to return it to the appropriate consistency.
  9. Enjoy your decorated cookies: Once dry, your beautifully iced, stackable cookies are ready to serve, share, or gift.

Notes

  • Sifting powdered sugar is crucial to avoid lumps in the icing.
  • Use gel food coloring for vibrant colors without thinning your icing.
  • Adjust the icing thickness depending on your decoration technique.
  • Allow enough drying time to ensure a firm finish that won’t smudge or stick.
  • Store leftover icing properly to prolong usability.
