Sugar Cookies with Royal Icing
By Pippa Calloway
Rate this recipe
Cut-out sugar cookies finished with royal icing are the canvas of American baking, the cookie that turns a kitchen table into a decorating studio every December and every birthday. The dough here is the classic rolled sort: butter and sugar creamed until smooth, bound with a single egg and vanilla, then stiffened with flour and a touch of baking powder so the cookies hold a sharp edge through the oven. The hour-long chill is not optional fussiness; it firms the butter so the shapes keep their lines instead of spreading into blobs, and it relaxes the dough so it rolls without snapping back. What sets these apart from a soft drop cookie is the royal icing, made from powdered sugar and meringue powder whipped with water until it holds stiff peaks. Meringue powder is the modern, food-safe stand-in for raw egg whites, and it lets the icing dry to a hard, glossy shell you can stack, bag, and ship. Thin it with a little water for flooding the centers, keep it stiff for piping crisp outlines, and you have the two-consistency system every cookie decorator relies on. These cookies are as much craft as recipe: a sturdy, lightly sweet base built to carry color, detail, and a steady hand. Bake them just to pale gold so they stay tender under all that icing.
Ingredients
Serves 30Instructions
- 1
Cream butter and sugar until smooth. Beat in egg and vanilla.
- 2
Combine flour and baking powder; mix into the creamed mixture. Chill dough for 1 hour.
- 3
Preheat oven to 400°F (200°C). Roll out dough on floured surface to 1/4 to 1/2 inch thick.
- 4
Cut into shapes with cookie cutters. Place on ungreased cookie sheets.
- 5
Bake 6 to 8 minutes (400°F / 200°C). Cool completely.

For icing: beat powdered sugar, meringue powder, and 5 tbsp water until stiff peaks form. Add more water if needed for consistency. Decorate cookies.
Chef's Tips
- ✦ Roll the dough between two sheets of parchment to an even quarter-inch; consistent thickness is the single biggest factor in cookies that bake evenly and don't burn at the edges.
- ✦ Chill the cut shapes again on the sheet for ten minutes before baking; cold dough hitting a hot oven holds its outline crisply.
- ✦ Bake only to pale gold, six to eight minutes; any browning makes a cookie too crisp to carry royal icing comfortably.
- ✦ Make two icing consistencies from one batch: stiff for piping outlines, then thin a portion with water drop by drop for flooding the centers.
- ✦ Test flood consistency with the ten-second rule: a knife drawn through the icing should smooth back over in about ten seconds.
- ✦ Let outlined cookies set 15 minutes before flooding so the border acts as a dam, and dry decorated cookies fully overnight before stacking.
Ingredient Substitutions
-
meringue powder → pasteurized egg whites or dried egg white powder
Both whip to stiff peaks for safe royal icing; pasteurized whites avoid any raw-egg concern.
-
butter → vegan baking stick butter
Choose a firm stick style, not a soft spread, so the dough chills hard and holds cut-out edges.
-
vanilla extract → almond extract or clear vanilla
Almond gives a bakery flavor; clear vanilla keeps white icing and dough from yellowing.
-
all-purpose flour → 1:1 gluten-free baking flour with xanthan gum
Roll a touch thicker and chill well; gluten-free dough is more fragile to transfer.
-
sugar → superfine (caster) sugar
Finer crystals cream into the butter faster for a smoother, more even cookie texture.
-
powdered sugar → sifted confectioners' sugar
Always sift before making icing; lumps clog piping tips and leave bumps in flooded surfaces.

Frequently Asked Questions
Why do I have to chill the dough for an hour? ▼
Chilling firms the butter and relaxes the gluten so the cookies hold their cut shapes instead of spreading and so the dough rolls without shrinking back. Skipping it gives blobby, distorted cookies.
Is royal icing made with meringue powder safe to eat? ▼
Yes. Meringue powder is dried, pasteurized egg white, so the icing is food-safe without any raw egg; that is exactly why decorators use it instead of fresh whites.
How long does royal icing take to dry? ▼
Outlines set in about 15 minutes, but fully flooded cookies need to dry uncovered overnight (8 to 12 hours) before they are hard enough to stack or package without smudging.
Can I make the dough or cookies ahead? ▼
Yes. The dough keeps refrigerated for three days or frozen for three months, and baked undecorated cookies hold airtight for a week, so you can spread the work over several days.
How do I get two icing consistencies from one batch? ▼
Keep part of the stiff-peak icing for piping outlines, then add water a few drops at a time to the rest until a drawn line smooths over in ten seconds, which is the right flooding consistency.
How do I store decorated sugar cookies? ▼
Once the icing is bone-dry, store them airtight at room temperature for up to a week with parchment between layers; do not refrigerate, as condensation can make the icing colors bleed.
