Ingredients

For the Sugar Cookies:

• 2 ½ cups (300g) all-purpose flour, plus more for dusting
• 1 teaspoon baking powder
• ½ teaspoon salt
• 1 cup (226g) unsalted butter, softened
• 1 ½ cups (300g) granulated sugar

• 2 teaspoons pure vanilla extract

For the Royal Icing:

• 4 cups (480g) powdered sugar (confectioners’ sugar), sifted
• 3 tablespoons meringue powder
• ½ cup (120ml) warm water, plus more as needed
• 1 teaspoon pure vanilla extract (optional)
• Navy blue gel food coloring

For Decoration:

• White nonpareil sprinkles (or very fine white sanding sugar)
• White star-shaped sprinkles (edible)

Instructions

Part 1: Preparing the Sugar Cookies

• In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
• In a large bowl, using an electric mixer, cream together the softened butter and granulated sugar on medium speed until light and fluffy, about 2-3 minutes.
• Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
• Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix. The dough will be thick.
• Divide the dough into two equal portions, flatten each into a disk, wrap tightly in plastic wrap, and refrigerate for at least 1 hour, or preferably 2-3 hours. Chilling the dough is crucial for preventing spread and ensuring your cookies hold their shape.
• Preheat your oven to 375°F (190°C). Line two baking sheets with parchment paper.
• On a lightly floured surface, roll out one disk of chilled dough to about ¼-inch thickness. Use a round cookie cutter (approximately 3-inch diameter) to cut out shapes.
• Carefully transfer the cut-out cookies to the prepared baking sheets, leaving about 1 inch between them. Reroll any dough scraps until all dough is used.
• Bake for 8-10 minutes, or until the edges are lightly golden brown. The centers should still be soft.
• Remove cookies from the oven and let them cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. It’s essential that the cookies are entirely cool before decorating with royal icing.

Part 2: Making and Coloring the Royal Icing

• In a large bowl, combine the sifted powdered sugar and meringue powder.
• Gradually add ½ cup warm water and vanilla extract (if using) to the sugar mixture. Using an electric mixer on low speed, beat until combined.
• Increase speed to medium-high and beat for 5-7 minutes, until the icing is thick, glossy, and holds stiff peaks. If the icing is too thick, add more water, ½ teaspoon at a time, until desired consistency is reached. If it’s too thin, add more sifted powdered sugar.
• Divide about ¾ of the royal icing into a separate bowl. This will be your “flood” consistency icing. Add tiny amounts of warm water (¼ teaspoon at a time) to this portion, stirring gently until the icing is thin enough to flow smoothly but still thick enough to hold a soft peak for a few seconds when a spoon is lifted. A good test is to dip a spoon into the icing; if the line left by the spoon disappears within 10-15 seconds, it’s the right flood consistency.
• To the remaining ¼ of the original, stiffer royal icing, add a few drops of navy blue gel food coloring. Mix thoroughly until you achieve a deep, consistent navy blue color. This will be your “outline” consistency icing. If it feels too stiff, add a tiny drop of water.
• To the larger bowl of flood consistency icing, add more navy blue gel food coloring until it matches the outline color. Mix well.
• Transfer the outline consistency blue icing into a piping bag fitted with a small round tip (like Wilton #2 or #3).
• Transfer the flood consistency blue icing into another piping bag, or a squeeze bottle, for easier application.

Part 3: Decorating the Galaxy Star Sugar Cookies

• Take a completely cooled sugar cookie. Using the piping bag with outline consistency blue icing, carefully pipe an outline around the edge of the cookie.
• Immediately after outlining, use the piping bag or squeeze bottle with flood consistency blue icing to fill in the outlined area. Gently spread the icing to the edges using a small offset spatula or a toothpick, ensuring the entire surface is covered smoothly.
• While the blue flood icing is still wet, immediately sprinkle a generous amount of white nonpareil sprinkles evenly over the entire surface of the cookie. These will be your distant stars.
• Next, carefully place a few white star-shaped sprinkles onto the wet blue icing. Arrange them randomly, as if they are brighter stars in your galaxy.
• Repeat the outlining, flooding, and sprinkling process for all remaining cookies.
• Once all cookies are decorated, let them dry completely at room temperature. This is the most crucial step for royal icing! Depending on humidity, this can take anywhere from 6-8 hours, or ideally, overnight, to fully harden. Do not stack or touch the decorated surface until completely dry.
• Once the icing is fully set and hard to the touch, your Galaxy Star Sugar Cookies are ready to be admired and enjoyed!

Cooking Tips and Variations

For the Perfect Sugar Cookie Base:

• Don’t Overmix: Overmixing the dough can develop the gluten too much, resulting in tough cookies. Mix until just combined.
• Chill, Chill, Chill: Seriously, don’t skip the chilling step for the dough. It prevents the cookies from spreading too much in the oven, ensuring they maintain their crisp edges and round shape, which is essential for decorating.
• Even Thickness: Roll your dough to an even ¼-inch thickness. This ensures all cookies bake uniformly and have a consistent texture.
• Flour Lightly: When rolling out the dough, use just enough flour to prevent sticking. Too much flour can dry out the dough and make the cookies tough.

Royal Icing Mastery:

• Sift Powdered Sugar: Always sift your powdered sugar for royal icing. This removes any lumps and ensures a smooth, uniform consistency, preventing clogs in your piping tips.
• Gel Food Coloring is Key: Use gel food coloring instead of liquid. Liquid food coloring can thin your icing too much, while gel provides vibrant color without significantly altering the consistency. For a deep navy, start with a good amount of blue and add a tiny touch of black if needed, but be careful not to make it too dark.
• Consistency is Crucial: Mastering royal icing consistency takes practice. Have extra powdered sugar and water on hand to adjust as needed. For outlining, you want it stiff enough to hold a line but soft enough to flow. For flooding, it should be thin enough to spread but not so thin that it runs over the edges.
• Work Quickly with Sprinkles: Apply all sprinkles (both nonpareils and stars) immediately after flooding a cookie, while the icing is still wet. This ensures they adhere properly and don’t fall off once the icing dries.
• Air Bubbles: After flooding a cookie, gently tap the baking sheet or cookie a few times on the counter. This helps to release any trapped air bubbles in the icing, resulting in a smoother finish. You can also use a toothpick to pop any stubborn bubbles.

Variations for Your Celestial Treats:

• Different Galaxy Colors: Experiment with other cosmic color palettes! Think deep purples, teals, or even a blend of colors for a swirling galaxy effect. You could use multiple colors of flood icing and marble them together with a toothpick.
• Glittering Stars: For extra sparkle, once the royal icing is completely dry, you can lightly brush the cookies with edible silver or gold luster dust using a clean, soft brush.
• Constellation Cookies: Instead of random stars, use edible ink pens to draw specific constellations onto your dried blue icing, or arrange star sprinkles to form them.
• Moon Cookies: Use a crescent moon cookie cutter and decorate them with silver or white icing to complement your star cookies.
• Flavor Variations: Add a hint of almond extract or lemon zest to your sugar cookie dough for a subtle flavor twist.

Storage and Reheating

Storage:

Once your Galaxy Star Sugar Cookies are completely dry (this means the royal icing is hard to the touch and won’t smudge, typically 6-8 hours or overnight), they can be stored in an airtight container at room temperature for up to 1 week. Layer them gently between sheets of parchment paper to prevent any potential sticking or damage to the delicate decorations. Avoid refrigerating royal icing decorated cookies, as the condensation can cause the colors to bleed and the icing to become sticky. If you live in a very humid environment, storing them in an airtight container with a desiccant packet (food-safe) can help maintain their crispness.

For longer storage, these cookies freeze beautifully. Once the royal icing is completely dry and hard, place the cookies in a single layer on a baking sheet and freeze for about an hour until solid. Then, transfer them to an airtight freezer-safe container or a heavy-duty freezer bag, again layering with parchment paper. They can be stored in the freezer for up to 3 months. Thaw them at room temperature in their container before serving to prevent condensation.

Reheating:

Sugar cookies, especially those with royal icing, are not typically “reheated” in the traditional sense. They are best enjoyed at room temperature. If you have frozen the cookies, simply remove them from the freezer and let them sit in their airtight container at room temperature for several hours (or overnight) until fully thawed. This slow thawing process helps to minimize condensation, which could otherwise affect the royal icing. Do not microwave or bake these cookies to “reheat” them, as this will melt the royal icing and ruin the decorations.

Frequently Asked Questions

What is the difference between flood and outline consistency royal icing?

Outline consistency royal icing is thicker, similar to toothpaste, and is used to create a barrier around the edge of the cookie. This prevents the thinner flood consistency icing from running off the cookie. Flood consistency royal icing is thinner, resembling honey or shampoo, and is used to fill in the outlined area, creating a smooth, even surface. The outline icing should hold its shape, while the flood icing should spread and self-level.

Can I make the cookie dough or royal icing ahead of time?

Absolutely! The sugar cookie dough can be made up to 3-4 days in advance and stored tightly wrapped in the refrigerator, or frozen for up to 3 months. Thaw frozen dough in the refrigerator overnight before rolling. Royal icing can also be made ahead of time. Store it in an airtight container at room temperature, with a piece of plastic wrap pressed directly onto the surface of the icing to prevent a crust from forming. It will keep for about 3 days. You may need to stir it well and adjust the consistency with a tiny bit of water before use.

Why are my royal icing colors bleeding or fading?

Color bleeding usually occurs if the icing is too thin, if the cookies are stored in a humid environment, or if you apply too much food coloring. Ensure your icing is the correct consistency and allow cookies to dry completely in a low-humidity environment. Fading can happen if cookies are exposed to direct sunlight for extended periods. Store decorated cookies in a cool, dark place once the icing is dry.

My cookies spread too much in the oven. What went wrong?

The most common reasons for cookies spreading are insufficient chilling of the dough, using butter that is too soft or melted, or too much leavening (baking powder/soda). Always ensure your butter is softened but still cool to the touch, and strictly follow the chilling time for the dough. Also, avoid over-greasing your baking sheets; parchment paper is best for preventing spread.
