Classic Sugar Cookies with Royal Icing
Buttery sugar cookies with smooth royal icing are the kind of treat that makes a simple cookie tray feel special. Cut them into stars for Christmas, hearts for Valentine’s Day, or little circles for an afternoon of decorating with the kids.
These classic sugar cookies have lightly golden edges, tender centers, and a vanilla flavor that pairs beautifully with a thin layer of sweet icing. The dough is chilled before cutting and again before baking to help the cookies keep their shape. Once they have cooled, decorate them with an easy royal icing made with meringue powder.
Keep the decorating simple with white icing and sprinkles, or mix a few colors and turn each cookie into a tiny edible canvas.

Ingredients
For the Sugar Cookies
- 3 cups (360 g) all-purpose flour, plus a little more for rolling
- 1/2 teaspoon baking powder
- 1/2 teaspoon fine salt
- 1 cup (227 g) unsalted butter, softened but still cool
- 1 cup (200 g) granulated sugar
- 1 large egg, at room temperature
- 2 teaspoons vanilla extract
- 1/4 teaspoon almond extract, optional
For the Royal Icing
- 4 cups (480 g) powdered sugar, sifted
- 3 tablespoons meringue powder
- 6 tablespoons room-temperature water, plus more as needed
- 1 teaspoon clear or regular vanilla extract, optional
- Gel food coloring, optional
- Sprinkles, optional
Ingredient note: Meringue powder brands vary. Check the package directions and adjust the powder-to-water ratio if your brand recommends a different amount for 4 cups of powdered sugar. Most meringue powders contain egg, so this icing is not egg-free.
How to Make Classic Sugar Cookies
1. Mix the Dry Ingredients
Whisk the flour, baking powder, and salt in a medium bowl. Set aside. For the most consistent dough, weigh the flour. If using cups, spoon the flour into the measuring cup and level it off instead of scooping directly from the bag.
2. Cream the Butter and Sugar
In a large bowl, beat the butter and sugar on medium speed for about 2 minutes, until smooth and slightly lighter in color. Scrape down the bowl. Avoid beating until extremely fluffy; too much incorporated air can encourage spreading and puffing.
3. Add the Egg and Vanilla
Beat in the egg, vanilla, and optional almond extract until combined. Scrape the sides and bottom of the bowl again.
4. Finish the Dough
Add the dry ingredients and mix on low speed just until the flour disappears. The dough should be soft and hold together when pressed. If it looks crumbly, press a handful together before adding anything; it may simply need a few more seconds of mixing.
5. Roll and Chill
Divide the dough in half. Roll each portion between sheets of parchment paper to an even 1/4-inch thickness. Place the rolled sheets on a baking tray and refrigerate for at least 1 hour, until firm.
Rolling before chilling makes the dough easier to handle and helps you avoid adding too much extra flour.
6. Cut Out the Cookies
Heat the oven to 350°F (175°C). Line baking sheets with parchment paper.
Peel away the top parchment sheet and cut out your shapes. Transfer the cookies to the prepared sheets, leaving about 2 inches between them. Gather scraps, gently reroll, and chill again before cutting. Limit rerolling where possible to keep the cookies tender.
Refrigerate the cut cookies for 15 minutes before baking, especially if the dough has softened.
7. Bake and Cool
Bake one sheet at a time on the center rack for 9–12 minutes, until the surfaces look set and the edges are only just beginning to turn pale gold. Small or narrow shapes may finish sooner.
Let the cookies rest on the baking sheet for 5 minutes, then transfer to a wire rack. Cool completely before decorating.
How to Make Royal Icing
Combine the sifted powdered sugar and meringue powder in a clean mixer bowl. Add 6 tablespoons of water and the optional vanilla. Mix on low speed until moistened, then beat on medium-low for about 4–5 minutes, until smooth, thick, and able to hold a peak. Follow your meringue powder’s mixing instructions if they differ.
Avoid whipping at high speed, which can add excess air bubbles. If the mixture is too dry to combine, add water 1 teaspoon at a time.
Divide the icing into bowls and tint with gel coloring. Keep every bowl covered with plastic wrap touching the icing whenever it is not in use; exposed royal icing begins to crust quickly.
Outline and Detail Consistency
Thin a portion of icing with a few drops of water at a time until it pipes smoothly while holding its shape. A piped line should stay defined rather than immediately flattening into a puddle. Use this thicker icing for borders, dots, lettering, and small details.
Flood Consistency
Thin another portion until a ribbon of icing dropped back into the bowl disappears in roughly 12–15 seconds. This is a starting point, not an exact rule: the icing should level out without running over the cookie’s edge.
If it disappears immediately, stir in a little sifted powdered sugar. If it leaves ridges for too long, add a few drops of water and test again.
How to Decorate the Cookies
- Outline the cookie. Pipe a thin border just inside the edge using outline icing.
- Fill the center. Add flood icing inside the border while the outline is still slightly wet. Do not overfill.
- Smooth the surface. Use a cookie scribe or clean toothpick to guide icing into corners and pop visible air bubbles.
- Add wet decorations. Scatter on sprinkles immediately. For wet-on-wet dots or stripes, pipe another color of flood icing onto the wet base.
- Let the base set for raised details. Wait until the base is firm before adding lettering or decorative lines. For dark details on a light base, allowing the base to dry fully can help reduce bleeding.
- Dry flat. Leave cookies in a single layer at room temperature, protected from dust. Allow 8–12 hours, or up to 24 hours in humid conditions or with thicker icing, before stacking or bagging.
A dry surface does not always mean the icing underneath has hardened. Decorate one extra cookie as a tester so you can check the finish before packaging the rest.
Simple Decorating Ideas
- Classic white cookies: Flood with white icing and finish with a few tiny white sugar pearls.
- Pastel hearts: Use pale pink, lavender, and peach icing with a small contrasting dot border.
- Christmas stars: Decorate with white icing and gold sprinkles, or add thin green branches once the base sets.
- Polka-dot rounds: Pipe small dots onto wet flood icing for a smooth, playful pattern.
- Birthday cookies: Use one bright icing color and a scattering of rainbow sprinkles.
Tips for Better Cutout Cookies
Keep the dough cool. If shapes stretch when you lift them, return the dough to the refrigerator until firm.
Use cool baking sheets. A warm tray softens the butter before the cookies reach the oven.
Roll to an even thickness. Thin edges brown faster, while thick centers take longer to bake.
Start with a few icing colors. Two or three coordinated colors can create a polished set without lots of extra bowls and piping bags.
Test the icing first. Decorate one cookie and watch whether the icing settles smoothly or spills over the border before filling the entire batch.
Storage and Make-Ahead Tips
Undecorated cookies: Store cooled cookies in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months.
Decorated cookies: Once the icing is completely dry, store airtight at room temperature for up to 5 days for best texture. Separate layers with parchment paper.
Cookie dough: Refrigerate tightly wrapped dough for up to 2 days, or freeze for up to 2 months. Thaw frozen dough in the refrigerator and let it soften just enough to roll if needed.
Leftover icing: Follow your meringue powder manufacturer’s storage instructions. Keep icing tightly covered, stir gently before using, and recheck the consistency.
Freezing decorated cookies: Once fully dry, pack cookies carefully in an airtight freezer container with parchment between layers. Freeze for up to 2 months. Thaw inside the closed container to help keep condensation off the icing. Delicate details and some colors may change after freezing; test a cookie first if appearance is especially important.
Frequently Asked Questions
Why did my sugar cookies spread?
The butter or dough may have been too warm, the baking sheet may have been hot, or the flour measurement may have been low. Chill the cut shapes before baking and use a scale for the flour when possible.
Why is my dough cracking when I roll it?
Very cold dough can crack at the edges. Let it sit for a few minutes, then gently press the edges together and roll again. Excess flour can also make dough dry, so use parchment rather than heavily flouring the counter.
Can I skip the almond extract?
Yes. The vanilla gives these cookies plenty of flavor on its own.
Does royal icing stay soft?
Royal icing dries firm on the outside and creates a sweet shell. The cookie underneath remains tender when baked without excessive browning and stored airtight.
Why is my royal icing not drying?
It may be too thin, applied too thickly, or drying in a humid room. Give it more time in a dry space with gentle airflow. Avoid refrigerating the cookies to set the icing, since condensation can affect the finish.
Can kids decorate these cookies?
Yes. Bake and cool the cookies ahead of time, then set out small piping bags, a few colors, and sprinkles. For younger children, spreading a thin layer of icing with a spoon is easier than outlining and flooding.
