This Sugar Cookie Icing that Hardens is great for decorating cutout Christmas cookies. The recipe results in a smooth, firm and glossy icing that dries quickly. It requires just 3 Ingredients, and is so easy to make.
Sift powdered sugar into a medium to large mixing bowl.
Add water, corn syrup and vanilla to bowl.
Stir with spatula until icing is smooth and uniform.
Divide mixture into smaller bowls and add coloring to attain desired shade.
Notes
Omit the vanilla extract or use a clear vanilla if you would like a white icing.
Smooth any icing sugar lumps by smooshing with a spatula against the side of the bowl.
If your icing seems too thick, add small amounts of water to get to the right consistency.
Is your icing too thin? Add a bit more powdered sugar.
Use a decorating squeeze bottle for easier decorating.
If you add too much icing in one spot, use a toothpick to move the excess around.
If using natural food coloring like I did, you will need quite a bit of coloring to achieve “bright” colors.
Allow your icing to harden for at least a few hours before checking them. Do not stack, store or freeze them until completely hardened. It can take the icing up to 24 hours depending on your environment
