How to Make Cookie Icing
Step 1: Mix the Icing
- In a medium bowl, whisk together powdered sugar, 2 tbsp milk, corn syrup, and vanilla extract until smooth.
- If the icing is too thick, add more milk ½ tsp at a time. If it’s too thin, add more powdered sugar.
Step 2: Color the Icing (Optional)
- Divide the icing into small bowls and add gel food coloring to each. Mix well.
Step 3: Decorate Your Cookies
- Transfer icing to a piping bag or ziplock bag with a small tip.
- Outline the cookies first, then flood the inside by spreading with a toothpick or spoon.
Step 4: Let It Harden
- Allow decorated cookies to dry at room temperature for 12-24 hours until fully set.
