Ingredients

  • 2 cups (260 g) powdered sugar
  • 2 tablespoons water Note 1
  • 2 tablespoons light corn syrup optional Note 2
  • 1 teaspoon pure vanilla extract optional Note 3

Instructions

To make the icing:

  • Add powdered sugar in a bowl and stir in water (or milk), corn syrup and vanilla extract, if using.
  • Mix 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. It's perfect consistency for outlining and filling sugar cookies.
  • 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 add food coloring to make colored icing.

To decorate cookies:

  • Transfer the icing into a squeeze bottle, or a piping bag with small round tip. Decorate the cookies and let the icing set. (TIP: If you want to stack and package the glazed cookies, make sure to let the icing set overnight.)

Notes

Note 1: While water works just fine, you may use milk for creamy flavor. For decorating cookies, I use water. For drizzling cakes and pastries, I like to use milk for a nice and creamy glaze.
Note 2: Light corn syrup adds a nice sheen to the icing once it's set. It's perfect addition for decorating sugar cookies. But you can totally skip it. I don't add corn syrup when making an icing for drizzling on cakes and pastries.
Note 3: Flavor your icing with different extracts and juices. Here're a few suggestions: 1 teaspoon of pure vanilla extract, lemon, lime or orange juice, Amaretto or Grand Marnier liquors. Or ½ teaspoon pure almond extract or mint extract.
Storing Tip:
- Powdered sugar icing made with water can be stored on the counter for up to 1 week.
- Refrigerate sugar glaze with milk for up to 3 days.
- You can also freeze the icing for up to 3 months.
