tips to make Best Sugar Cookie Icing
- Start with a small amount of water and add more to reach the right flow.
- For outlines, use slightly thicker icing. For flooding, thin it a touch more.
- Work on cooled cookies so the icing sets fast.
- Use clear piping bags or zip-top bags with the corner cut for easy piping.
- Mix colors slowly; food color can darken as it dries.
variation (if any)
- Add almond or lemon extract instead of vanilla for flavor.
- Make thicker icing for fine details and thinner icing for flooding large areas.
- Use gel food colors for bright tones without thinning the icing too much.
