Royal Icing vs Sugar Glaze Icing
Royal icing is made of meringue powder or whipped egg whites and powdered sugar. It sets quickly and ideal for intricate piped designs!
Easy glaze icing, on other hand, is made of powdered sugar and liquid. While it’s quite easy to work with, it takes a little longer to set. But once set, you can stack the glazed cookies.
Simple Icing Recipe Ingredients
You can make the simplest icing with just powdered sugar and water. It’ll taste nothing but sugar, and I love it that way.
But, you can also jazz up this basic version with vanilla extract, milk and corn syrup. Milk makes the glaze nice and creamy. And corn syrup yields a glaze with a nice sheen after drying.

How to make Icing with Powdered Sugar
This method is practically foolproof. And to be perfectly honest, I don’t even measure anything.
- Add powdered sugar in a bowl and stir in water (or milk, or vanilla extract) until the desired consistency is reached.
- To test the consistency, let the glaze pour off the spoon. The glaze should fall into a ribbon and hold the shape for a few seconds before melting back into the glaze.

Sugar Glaze Tips and Tools
- If the glaze is too thick, add a drop of water and test again.
- If the glaze is too runny, add a little more powdered sugar.
- Feel free to color the icing with any food coloring (water-soluble).
- If using vanilla extract, add it first and then add water (or milk) a little at time until proper consistency reached.
- If you want your icing set with a nice sheen, add 1 teaspoon light corn syrup.
- Use a squeeze bottle or piping bag with round tip for decorating cookies.
- If using colored sugar or sprinkles on top of the icing, add them immediately after icing the cookies.
- Let the glazed cookies set overnight before stacking and packaging.
