Powdered Sugar Frosting: The Ultimate Glossy White Cookie Icing Recipe
Introduction
Powdered sugar frosting is a classic, glossy white icing perfect for decorating cookies with a smooth, shiny finish. This easy recipe delivers a sweet, creamy topping that sets beautifully, making your baked treats look professionally decorated.

Ingredients
- 4 cups powdered sugar (480g, sifted)
- 4-6 tablespoons whole milk (60-90ml; use heavy cream for extra richness)
- 2 teaspoons light corn syrup (10ml, provides the high-shine finish)
- 1 teaspoon vanilla extract (5ml; use clear vanilla for the brightest white)
- 1 pinch fine salt (to balance sweetness)
Instructions
- Step 1: Sift the powdered sugar into a medium bowl to ensure a smooth texture without lumps.
- Step 2: Add the corn syrup, vanilla extract, salt, and 4 tablespoons of milk to the sifted sugar.
- Step 3: Stir the mixture with a spoon until a thick, creamy paste forms.
- Step 4: Gradually add the remaining milk one teaspoon at a time, stirring each addition, until the icing falls in a slow, opaque ribbon from the spoon.
- Step 5: Hold a golden-brown sugar cookie and dip it halfway into the frosting. Lift it straight up and let the excess drip back into the bowl.
- Step 6: Place the dipped cookie on a wire rack to set and dry completely.
Tips & Variations
- For a richer flavor, substitute whole milk with heavy cream.
- Use clear vanilla extract to keep the frosting bright white and avoid discoloration.
- If the frosting becomes too thick, add a few drops of milk to reach the desired consistency.
- Add a few drops of food coloring to customize the frosting for different occasions.
