Gather ingredients: Begin by collecting all your icing ingredients on a clean surface. This ensures a smooth workflow, making the process enjoyable and hassle-free.

Mix together: In a medium bowl, combine the sifted powdered sugar, milk, light corn syrup, and vanilla extract. Stir together until the mixture is creamy and smooth, about 1-2 minutes.

Adjust consistency: If your icing feels too thick, add an extra splash of milk, mixing well. Aim for a silky-smooth texture that can flow easily for decorating, but still holds its shape on cookies.

Add color: If you'd like to make your cookies pop, now’s the time to add a few drops of food coloring. Stir thoroughly to achieve an even color throughout the icing.

Decorate your cookies: Time to unleash your creativity! Use a piping bag or a simple dipping technique to cover your cooled cookies with the icing. Have fun with designs—you’re the artist here!

Let harden: Place your decorated cookies on a cooling rack and allow them to sit at room temperature for about 6 to 8 hours. You'll know they are ready when the icing feels firm and non-sticky to the touch.
