This royal icing recipe without eggs is the best cookie decorating icing. It is made with just four simple ingredients. It dries shiny, hardens beautifully for decorating, and tastes delicious.
Combine powdered sugar, water, light corn syrup, and vanilla extract in a large bowl. Stir until the mixture is smooth and well combined.
To check for the correct consistency let some of the icing run off of a spoon and you want it to settle back into the bowl within about 12 seconds.
Optional: Add in a drop of food gel at a time. A little bit goes a long way. Stir until desired color. The more you stir, the thicker the icing will become so you may need to add in a teaspoon of water to thin it out.
To decorate: You can dip the cookies into the icing or using piping bags to decorate the cookies. See notes for cookie decorating tips.

Notes
Pair this recipe with eggless cut-out sugar cookies!Serving size: This would decorate about 36 medium cookies. For large cookies it could decorate about 24 large cookies. It could decorate more if you are just outlining them and not filling them completely in.Drying time: The icing takes about 6 hours to completely harden. Storage: If you are not using the icing right away, cover with plastic wrap. I recommend using it within that first day. Give it a good stir and add some water if needed to bring it back to the right consistency.Decorating tips: Start by outlining the cookie, then fill in the inside. This helps keep the icing from running over the edges. I encourage you to watch the video for more decorating tips
