Sift powdered sugar into a medium bowl. Add 6 teaspoons milk, corn syrup, and extract. Stir vigorously until icing is smooth and no lumps remain.
If needed, add additional milk to thin icing. Test the desired consistency for spreading by lifting a spoonful from the bowl. It should drizzle back down slowly and mound gently. If making colored icing, divide into small bowls and stir in food colorings.
