Ingredients
- 2 cups powdered sugar
- 1/4 cup milk
- 1 teaspoon vanilla extract
- 1 tablespoon light corn syrup
- Food coloring (optional)

How to Make It
In a mixing bowl, combine the powdered sugar, milk, vanilla extract, and corn syrup. Stir until smooth and glossy. Mix thoroughly so the icing has an even texture without visible pockets of powdered sugar.
If desired, divide the icing into separate bowls and add food coloring to each. Stir each portion until the color is evenly blended. You can create one color or several shades for detailed cookie decorating.
Use the icing to decorate your cooled sugar cookies, allowing it to dry completely before stacking. Spread or drizzle the icing over the cookies, then let it set fully so the designs remain neat and do not stick together.
How to Serve It
- Decorate cooled sugar cookies with colorful icing for holiday cookie trays, birthdays, or celebrations.
- Add sprinkles while the icing is still wet for extra color and texture.
- Arrange the finished cookies with other baked treats, such as brownies, cupcakes, or plain butter cookies.
How to Store It
Store leftover icing in an airtight container in the refrigerator. Before using it again, stir it well to restore a smooth consistency.
Decorated cookies should be allowed to dry completely before placing them in an airtight container. Separate layers with parchment paper if needed, and avoid stacking them until the icing has set.
Freezing instructions are not provided for this recipe. Do not reheat the icing, as heat can affect its texture and glossy finish.
Helpful Tips
- Use cooled sugar cookies before decorating so the icing remains smooth and does not soften the cookies.
- Stir until the icing is completely smooth and glossy before adding food coloring or decorating.
- If using multiple colors, divide the icing into separate bowls before coloring to keep each shade clean and even.
Optional Variations
- Divide the icing into several bowls and use different food colors to create colorful holiday or party cookies.
- For a simple decorative look, leave the icing white and add sprinkles while it is still wet.
- Create layered designs by using multiple icing colors on the same cooled sugar cookie.
