How to Make Christmas Lights Royal Icing Sugar Cookies Recipe
1. Mix the dough
- Cream butter and sugar on medium speed for 2 minutes until pale and fluffy.
- Beat in the egg and vanilla until smooth.
- Whisk flour, baking powder, and salt. Add in two additions on low speed until the dough comes together and pulls from the bowl.
2. Chill and preheat
- Divide dough in half, flatten into disks, and wrap. Chill 30 to 45 minutes until firm but pliable.
- Preheat oven to 350°F. Line baking sheets with parchment.
3. Roll and cut
- Lightly flour the surface. Roll one disk to 1/4 inch thick.
- Cut shapes and transfer to trays, leaving 1 inch space.
- Gather scraps, re-roll once to avoid tough cookies.
4. Bake
- Bake 9 to 11 minutes until edges look set and bottoms turn light golden.
- Cool 5 minutes on the tray, then move to a rack to cool completely.
5. Mix royal icing
- Whisk powdered sugar and meringue powder. Add 6 tablespoons water and vanilla.
- Beat on medium-high for 2 to 3 minutes until thick, glossy peaks form.
- Adjust: Thin small portions with water to get flood consistency that settles in 10 to 12 seconds. Keep outline icing thicker, about toothpaste thickness. Add a few drops corn syrup to the flood bowl for extra shine if you like.
6. Color and bag
- Tint a portion black for the string with gel color.
- Divide the rest into four small bowls and tint red, green, blue, and yellow for bulbs.
- Load piping bags: thick white for outline, thin white for flood, black for string, and small bags with colored icings for bulbs.
7. Outline and flood
- Pipe a thin white outline around cookie edges with the thicker icing.
- Fill with flood icing. Nudge into corners with a scribe and pop air bubbles.
- Let the base coat set 30 to 60 minutes until the surface firms up.
8. Pipe the light string
- With black icing and a #2 tip, draw a loose, wavy line across the cookie like a cord. Add tiny sockets by dotting small bumps along the line where bulbs will sit.
- Let the string crust 10 to 15 minutes to keep colors from bleeding.
9. Add the bulbs
- With colored icings and a #1 or #2 tip, pipe small teardrops or dots at each socket. Pull slightly to a point for a bulb shape.
- Rotate through colors for a classic strand look. Add a tiny white dot of icing on each bulb for a shine spot.
10. Dry
- Let cookies dry uncovered at room temp 8 to 12 hours until the icing hardens fully.
- Keep pets, dust, and humidity away. I use a large sheet pan as a tent to guard the artwork.
Tips & Common Mistakes
- Chill the dough so the shapes keep sharp edges.
- Roll evenly to 1/4 inch so cookies bake at the same rate.
- Use parchment, not a greased sheet, to prevent spread.
- Do not overbake; pull when edges set and bottoms lightly color.
- Sift powdered sugar to avoid icing lumps.
- Keep a damp towel over icing bowls to prevent crusting.
- Test icing thickness on a spoon; adjust with a few drops of water or a dusting of sugar.
- Let layers crust before adding the next color to prevent bleeding.
- Use gel colors, not liquid, so icing holds shape and hue.
- Work with small icing amounts in piping bags; refill often so heat from your hands does not thin it.
- Practice the light string on parchment, then pipe on cookies with confidence.
- Store decorated cookies only after the icing hardens completely to avoid smudges.
Variations I've Tried
- Chocolate sugar cookies: Swap 1/2 cup flour for 1/2 cup Dutch-process cocoa and add 1 tablespoon milk.
- Citrus twist: Add 1 teaspoon orange zest to dough and 1/2 teaspoon orange extract to icing.
- Peppermint lights: Add 1/2 teaspoon peppermint extract to the flood icing and finish with a light peppermint sprinkle.
- Sparkle bulbs: Dip wet bulbs in matching sanding sugar for a glow effect.
- Sprinkle strand: Pipe the black string, then set mini nonpareils along the line for a dotted cord look.
How to Serve
Set these Christmas lights sugar cookies on a platter with hot cocoa, coffee, or a mulled cider. Pair with salty snacks like spiced nuts or a cheese board to balance the sweetness. I also pack them in tins with parchment dividers for a festive gift that travels well. Add a tiny tag that says which colors you used so kids can hunt for their favorite bulb.
Make-Ahead and Storage
- Make-ahead dough: Wrap tightly and chill up to 3 days or freeze up to 2 months. Thaw overnight in the fridge.
- Baked undecorated cookies: Store airtight at room temp up to 4 days or freeze up to 2 months.
- Decorated cookies: Let icing harden fully, then store in single layers with parchment between them in an airtight container at cool room temp for 7 to 10 days.
- Freezing decorated cookies: Freeze in a rigid container with parchment layers for up to 1 month. Thaw in the closed container to avoid condensation on the icing.
- Revive texture: If cookies feel a bit soft after storage, place them uncovered on the counter for 30 minutes. They firm back up and keep that nice bite.

Ingredients
Instructions
- Cream the butter and granulated sugar together on medium speed for about 2 minutes, until pale and fluffy.
- Beat in the egg and vanilla extract until the mixture is smooth and well combined.
- In a separate bowl, whisk together the all-purpose flour, baking powder, and fine sea salt. Add the dry ingredients to the wet ingredients in two additions on low speed, mixing just until the dough comes together and pulls away from the sides of the bowl.
- Divide the dough in half, flatten each portion into a disk, and wrap tightly. Chill in the refrigerator for 30 to 45 minutes, until firm but still pliable.
- Preheat the oven to 350°F (175°C). Line baking sheets with parchment paper.
- Lightly flour your work surface. Roll one disk of dough to about 1/4 inch thickness.
- Cut out cookie shapes with cookie cutters (circles, ornaments, or rectangles work well) and transfer them to the prepared baking sheets, leaving about 1 inch between cookies.
- Gather scraps, gently re-roll once, and cut additional cookies.
- Bake for 9 to 11 minutes, until the edges look set and the bottoms are just turning light golden.
- Cool cookies on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely before decorating.
- In a bowl, whisk together the sifted powdered sugar and meringue powder.
- Add about 6 tablespoons of water and the vanilla, then beat on medium-high speed for 2 to 3 minutes, until the icing is thick, glossy, and holds peaks.
- Adjust the consistency: keep some icing thick, about toothpaste consistency, for outlining and details. Thin portions with a few drops of water at a time to make flood icing that smooths out in 10 to 12 seconds when you drag a knife or spoon through it. If desired, stir a small amount of corn syrup into the flood icing for extra shine.
- Tint a portion of the icing black for the light string using gel food coloring.
- Divide the remaining icing into four small bowls and tint each portion red, green, blue, or yellow for the bulbs.
- Transfer thick white icing to a piping bag for outlining, thin white icing to a bag for flooding, black icing to a bag for the string, and each colored icing to small piping bags for the bulbs.
- Outline each cooled cookie with thick white icing to create a border.
- Fill the center with flood-consistency white icing. Use a toothpick or scribe tool to nudge the icing into corners and pop any air bubbles. Let the base coat set for 30 to 60 minutes, until the surface is firm.
- With black icing fitted with a small round tip, pipe a loose, wavy line across the cookie to resemble a string of lights. Add tiny bumps along the line where each bulb will sit to suggest sockets. Let the string crust for 10 to 15 minutes.
- Using the colored icings, pipe small teardrop shapes or dots at each socket to form the light bulbs, pulling slightly to a point if desired. Rotate through the colors for a classic strand look, and add a tiny dot of white icing on each bulb for a shine highlight. Decorate with sprinkles or sanding sugar if using.
- Allow the decorated cookies to dry uncovered at room temperature for 8 to 12 hours, or until the royal icing is fully hardened.
- Once dry, store the cookies in an airtight container with parchment between layers at cool room temperature.
