Frosted Sugar Cookies with Royal Icing

Headnote

A proper frosted sugar cookie should be delicate at the center, clean at the edge, and finished with icing that sets to a fine, glossy shell. The dough is restrained and buttery, with enough structure to hold a sharp shape and enough tenderness to melt cleanly on the tongue. Decoration should feel deliberate, not crowded.

Ingredients

Sugar cookie dough

Wheat flour 180 g
Baking powder 4 g
Salt 2 g
Butter, softened 90 g
Sugar 70 g
Egg 25 g
Vanilla extract 4 g

Royal icing

Powdered sugar 120 g
Corn syrup 12 g
Milk 10 g
Water 8 g
Vanilla extract 2 g
Food coloring 2 g

Cocoa decoration

Cocoa 3 g
Water 3 g

Method

1. Heat the oven to 175°C. Line a baking tray with parchment paper.

2. Sift the wheat flour, baking powder, and salt together. This ensures an even dough and prevents pockets of leavening.

3. In a separate bowl, beat the butter and sugar for 2 to 3 minutes until pale, smooth, and aerated. The mixture should look lighter in color and hold soft ridges.

4. Add the egg and vanilla extract, then mix just until fully incorporated. Scrape the bowl once to keep the dough uniform.

5. Add the dry ingredients and mix only until the dough comes together and no dry flour remains. The dough should be soft but not sticky.

6. Roll the dough between two sheets of parchment to a thickness of 6 mm. Chill for 15 minutes until firm enough to cut cleanly.

7. Cut the dough into neat shapes and place them on the prepared tray with a small gap between each piece. Bake for 10 to 12 minutes, until the edges are set and the centers remain pale with only the faintest golden tone at the base.

8. Cool the cookies on the tray for 5 minutes, then transfer them to a wire rack and cool completely. The surface must be fully cold before icing.

9. For the icing, sift the powdered sugar into a bowl. Add the corn syrup, milk, water, and vanilla extract, then mix until smooth and glossy. Divide and tint with the food coloring as desired. The icing should flow slowly from a spoon and settle into a smooth line within a few seconds.

10. Mix the cocoa with the water to a smooth paste. Use it for fine decorative accents.

11. Spoon or pipe the icing over the cooled cookies in a controlled layer. Add the cocoa decoration while the icing is still soft, then allow the surface to stand until set, about 30 to 40 minutes.

Plating and serving

Arrange the cookies in a single layer or on a shallow platter, keeping the decoration visible and clean. Serve at room temperature, when the cookie remains tender and the icing has a crisp, polished finish.

Professional notes

Roll the dough evenly; irregular thickness is the first cause of uneven color and texture.
Do not overwork the dough once the flour is added, or the cookie will lose its fine crumb.
Icing must be applied only to fully cooled cookies, or the surface will dull and the decoration will spread.
