Sift the flour, baking powder, and salt into a medium bowl.
PRO TIP If you don't have a sifter, use a whisk to mix dry ingredients together.

Place the butter and sugar in a large mixing bowl. Beat with a hand mixer on low speed to blend, then increase speed to medium and beat until soft and light. Add the egg and milk, followed by the flour mixture, beating after each addition until blended, and scraping down the sides of the bowl as needed.

Lay two sheets of plastic wrap on a work surface. Scrape half of the dough on each wrap and shape into a disk about 1/2-inch thick. Wrap the dough in plastic, then chill until firm enough to roll and hold its shape, 30-60 minutes.

Line two or four baking sheets with parchment paper.
PRO TIP If you don't have parchment paper, you can bake cookies on ungreased sheet pans.

Step 5 of 16
Christmas Sugar Cookies
Lightly flour a work surface and rolling pin and roll one dough disk to 1/4-inch thick, lifting and re-flouring the surface and rolling pin as needed to prevent sticking. Cut out cookies using any shapes you like. Transfer cookies to the prepared baking sheets, spacing them about 1 inch apart. Dust cookie cutters in flour if the dough starts to stick. Gather the scraps, re-roll, and cut again.
PRO TIP For crisper cookies, roll dough 1/8-inch thick and bake a few minutes less.

Christmas Sugar Cookies
To help the cookies retain their shapes, refrigerate on the baking sheets for 10-15 minutes while oven is preheating. Meanwhile, continue with second disk of dough. If dough starts to get too soft to cut, chill it again for a few minutes.
PRO TIP The dough keeps for up to three days in the refrigerator (wrapped airtight) if you want to make smaller batches of cookies over several days.

Christmas Sugar Cookies
Bake two pans of cookies at a time on upper-third and lower-third racks of oven, switching pan positions halfway through cook time, until cookies are light golden brown around the edges, 10-13 minutes.

Use a wide spatula to transfer cookies to cooling racks and let cool for about 15 minutes.

Step 11 of 16
Christmas Sugar Cookies
Make the royal icing: Sift the powdered sugar into a stand mixer bowl fitted with a whisk attachment. Add the meringue powder. With mixer on low speed, add water, 1 tablespoon at a time, until combined, scraping the bowl as needed. Increase speed to high and beat until icing is shiny, thickened, and smooth and holds a soft peak that flops over when whisk is lifted, 3-5 minutes. If the icing is too thick, add an additional tablespoon of water. If it falls off the whisk, add an additional 1/4 cup sifted powdered sugar. This is your outline icing.
PRO TIP Gel food coloring works better and produces truer colors than liquid food coloring because the color is more concentrated. If the icing in the bowls begins to harden before you use it, add 1 tsp. lemon juice or water and stir with a rubber spatula to loosen it.

Step 12 of 16
Christmas Sugar Cookies
Transfer one quarter of the icing to a small bowl and one quarter in another. Leave one bowl white and stir gel color into the other. Make the filling icing: Add the water, 1 teaspoon at a time, to the remaining icing in the stand mixer bowl, mixing on low speed. When the whisk is lifted, icing should droop and then slowly fall off. Divide the icing between two small bowls. Leave one bowl white and stir gel color into the other. Transfer each icing to a piping bag fitted with a small round decorating tip. Use your smallest tips (ideally, #3) for outline icing and slightly larger (ideally, #5) for filling icing.
PRO TIP To fill a piping bag, snip about 1 inch off the small end. Insert a decorating tip and gently squeeze it down until its opening comes out the end of the bag. Fold back the top of the bag, then set the bag upright in a sturdy glass or mug. Fill with icing about half full. Unfold the top of the bag, twist it closed, and squeeze until icing comes out the tip.

Pipe the outline icing over a few cookies at a time. To line with sprinkles, sparkling/sanding sugar, or cake sparkles, pour some onto a flat plate and invert the outlined cookies onto decor so sprinkles will stick to the icing. Use the outline icing to add details like faces. Finish with sugar pearls, if desired, for additional detailing.
PRO TIP Use the sharp end of a toothpick to blend or eliminate icing peaks.

Step 14 of 16
Christmas Sugar Cookies
To fill in a cookie completely with color, outline the cookie in icing first, then squeeze in filling icing, using the same color or a different one. Carefully spread the filling icing with a toothpick if needed. Top with sprinkles if desired, or invert cookies onto plates of sprinkles, sparkling/sanding sugar, or cake sparkles to cover completely.
PRO TIP Outlining the cookie first will keep the icing from spilling over. To create marbled cookies, just swirl colors together with a toothpick.

Icing takes a minimum of 30 minutes to 1 hour to completely set, but cookies can be eaten at any time. If transporting cookies, let icing set completely, about 1 hour.
