Ingredients You’ll Need

These Christmas Lights Sugar Cookies require simple baking ingredients for the cookie dough and a few essentials for the royal icing.

For the Sugar Cookies

• All-purpose flour: Provides structure and helps the cookies hold their shape when cut and baked. Measuring with a kitchen scale gives the most accurate results.
• Baking powder: Gives the cookies a little lift while keeping them tender.
• Salt: Balances the sweetness and enhances the buttery flavor.
• Unsalted butter: Adds richness and creates a tender, delicious sugar cookie. Make sure it’s softened to room temperature.
• Granulated sugar: Sweetens the dough and helps create the classic sugar cookie texture.
• Large eggs: Bind the ingredients together and provide structure. Room-temperature eggs blend more easily into the butter mixture.
• Pure vanilla extract: Adds warm vanilla flavor that complements the buttery cookie base.

For the Royal Icing

• Powdered sugar: Creates the smooth, sweet base of the royal icing.
• Meringue powder: Helps the icing whip into a thick consistency and dry firm enough for decorating.
• Water: Adjusts the icing to different consistencies for outlining, flooding, and adding details.
• Food coloring: Gel food coloring works especially well because it adds vibrant color without making the icing too thin. Use red, green, yellow, blue, or any Christmas colors you like.

How to Make Christmas Lights Sugar Cookies

The process is simple: prepare and chill the dough, cut and bake the cookies, then decorate them with colorful royal icing. Allow enough time for the icing to dry before stacking or packaging the finished cookies.

Step 1: Prepare the Sugar Cookie Dough

Preheat your oven to 350°F.

In a medium bowl, whisk together the all-purpose flour, baking powder, and salt until evenly combined. Set aside.

In a large mixing bowl, beat the softened butter and granulated sugar with an electric mixer for about 3 minutes, until creamy.

Add the eggs and vanilla extract. Beat for another minute until everything is well combined.

With the mixer running on low speed, gradually add the flour mixture. Continue mixing until the dough begins to pull away from the sides of the bowl.

Step 2: Knead and Chill the Dough

Transfer the dough onto a large piece of parchment paper. Use your hands to knead it for a few minutes until it comes together smoothly.

Divide the dough into two portions and wrap each portion in parchment paper. Refrigerate for about 30 minutes.

Chilling makes the dough easier to roll and cut while helping the cookies maintain their shapes during baking.

Step 3: Roll and Cut the Cookies

Place one portion of chilled dough between two sheets of parchment paper. Roll it evenly with a rolling pin until it’s between 1/8 and 1/4 inch thick.

Use your favorite Christmas cookie cutters to cut out the shapes. Remove the excess dough around the cookies, but leave the cut shapes in place on the parchment paper.

Carefully transfer the parchment paper with the cookies onto a baking sheet. Keeping the shapes in place helps prevent them from stretching or losing their form.

Repeat with the remaining dough, gathering and rerolling scraps as needed.

Step 4: Bake the Sugar Cookies

Bake the cookies at 350°F for 10–13 minutes, or until the edges are just slightly golden brown.

The centers should remain relatively pale. Avoid overbaking if you want soft, tender sugar cookies.

Remove the baking sheet from the oven and allow the cookies to cool before transferring them to a cooling rack. Make sure they are completely cool before decorating with royal icing.

Step 5: Make the Royal Icing

Add the powdered sugar, meringue powder, and 1/3 cup of water to a large mixing bowl.

Beat with an electric mixer on low speed for about 6 minutes. The icing will become very thick and fluffy.

Add 4–5 tablespoons of additional water and mix until combined. This creates the medium-consistency icing, which should resemble toothpaste.

Transfer half of the icing to a separate bowl. Add another 1–2 tablespoons of water to this portion, mixing until it reaches a thinner consistency that runs off a spoon like glue. This is your flood icing.

Divide the icing into smaller bowls and tint each portion with gel food coloring.

Keep the icing covered when you’re not using it so it doesn’t dry out.

Step 6: Decorate the Christmas Lights Cookies

Transfer the medium-consistency icing to a piping bag fitted with a small opening. Pipe an outline around the edges of each cookie.

Next, use the thinner flood icing to fill in the outlined areas. A plastic squeeze bottle makes this step easier, but you can also use a piping bag.

Spread the icing gently to cover the cookie surface, making sure it reaches the piped border.

Allow the base icing to dry for about one hour.

Once the surface has set, use the medium-consistency icing to pipe the Christmas light details. Add colorful light shapes in red, green, yellow, blue, or your favorite festive colors.

Let the decorated cookies dry completely before serving, stacking, or packaging.

Tips for Perfect Christmas Lights Sugar Cookies

• Measure the flour accurately: Too much flour can make the dough dry and difficult to roll. Weighing it with a kitchen scale is the most reliable method.
• Use softened butter: Butter should be soft enough to mix easily but not melted. This helps create a smooth, evenly mixed dough.
• Don’t skip chilling: Refrigerating the dough for 30 minutes makes it easier to handle and helps the cookies keep their shapes.
• Roll the dough evenly: Aim for a consistent thickness between 1/8 and 1/4 inch so the cookies bake evenly.
• Keep the cookies on the parchment: Removing excess dough around the cut shapes before moving the parchment helps prevent misshapen cookies.
• Watch the baking time: Bake until the edges are only slightly golden. Overbaking can make the cookies dry and crisp.
• Use gel food coloring: Gel colors provide bright, vibrant shades without adding too much liquid to the royal icing.
• Pay attention to icing consistency: Medium icing is best for outlining and details, while thinner flood icing fills the cookie surfaces smoothly.
• Let the icing dry: Allow the base layer to set for about an hour before adding the decorative details. Give the finished cookies enough time to dry completely before storing them.

Christmas Lights Sugar Cookie Variations

These cookies are easy to customize for different holiday themes and decorating styles.

1. Traditional Red and Green Christmas Lights

Use red, green, and yellow royal icing to create a classic Christmas color combination. Pipe the lights in alternating colors for a cheerful, traditional holiday look.

2. Multicolored Christmas Lights

Create a bright string of Christmas lights using blue, pink, purple, orange, yellow, red, and green icing. This colorful version is especially fun for kids and makes a beautiful addition to a Christmas cookie platter.

3. White and Gold Christmas Lights

For a more elegant look, use white royal icing as the base and decorate with gold, white, and pale yellow details. This creates a simple, sophisticated cookie that’s lovely for holiday parties.

4. Christmas Tree Light Cookies

Use Christmas tree-shaped cookie cutters and pipe a string of colorful lights winding around each tree. Add a small yellow star at the top for an extra festive touch.

5. Sprinkle Christmas Lights Cookies

If you want to simplify the decorating, add tiny festive sprinkles to the wet flood icing. You can still pipe the light details once the base has dried.

How to Store Christmas Lights Sugar Cookies

Once the royal icing has dried completely, store the cookies in an airtight container at room temperature. Keep them in a cool, dry place and avoid stacking them until the icing is fully set.

For longer storage, the undecorated baked cookies can be frozen before decorating. Place them in a freezer-safe airtight container with parchment paper between layers.

The cookie dough can also be prepared ahead of time and chilled before rolling and baking. This makes it easier to spread the holiday baking over a couple of days.

Frequently Asked Questions

Can I make Christmas Lights Sugar Cookies ahead of time?

Yes! You can prepare the cookie dough, bake the cookies, or make the royal icing ahead of time. The baked cookies can also be frozen before decorating for several months. When you’re ready, thaw them and decorate once they have reached room temperature.

Why does the sugar cookie dough need to chill?

Chilling firms up the butter and makes the dough easier to roll and cut. It also helps the cookies hold their shapes in the oven instead of spreading too much during baking.

How do I know when the sugar cookies are done?

The cookies are ready when the edges are just slightly golden brown. Depending on their size and thickness, baking takes about 10–13 minutes. Avoid waiting for the tops to turn golden, as this can result in overbaked cookies.

What is the difference between medium-consistency and flood royal icing?

Medium-consistency icing is thicker and works well for outlining cookies and piping decorative details. Flood icing is thinner and flows easily into the outlined areas to create a smooth surface.

Can I use regular food coloring instead of gel food coloring?

Yes, but gel food coloring is recommended because it provides more vibrant colors without adding much liquid. If you use liquid food coloring, add it gradually and watch the consistency of the icing.

How long does royal icing take to dry?

The base layer should dry for about one hour before you add the decorative details. The finished cookies need additional time to dry completely before stacking or storing. Drying time can vary depending on the thickness of the icing and the humidity in your kitchen.

Can I freeze Christmas Lights Sugar Cookies?

Yes. The baked, undecorated cookies can be frozen before decorating and kept for several months in a well-sealed freezer-safe container. Thaw them completely before adding royal icing.
