Classic Sugar Cookies

1 cup (2 sticks) salted butter, softened

¾ cup sugar

½ tsp salt

1 egg

1 tsp vanilla extract

1 tsp almond extract (optional)

2½ cups flour 

1 Tbsp cornstarch 

Royal Icing

½ cup + 2 Tbsp water, room temperature

1 tsp salt

⅓ cup meringue powder

2 lb. ( 8 cups) powdered sugar

1–2 tsp vanilla bean paste or extract

2–4 Tbsp light corn syrup

Instructions

In a stand mixer fitted with the paddle attachment (or a mixing bowl), cream the butter, sugar, and salt on low to medium-low until combined and slightly lightened. Scrape the bowl well.

Add the egg, vanilla, and almond extract, mixing until fully combined.

Add the flour and cornstarch all at once and mix on low until a dough forms. Scrape the bowl to make sure no dry spots remain.

Place the dough on lightly floured parchment or silpat mat, shape it into a disc, lightly flour the top, cover with another sheet of parchment, and roll to ¼". (Roll to 1/6–1/8" for crisp cookies or 5/16–3/8" for thicker ones.)

Refrigerate the rolled dough if you’d like (see tips) or use right away.

When ready to bake, preheat the oven to 375°F. Cut shapes from the chilled dough with lightly floured cutters and place on a parchment-lined sheet or use a silpat mat on your baking sheet.

Bake 10-12 minutes, until the tops are no longer shiny and the bottoms are lightly golden. Cool on the sheet for a few minutes, then transfer to a rack to cool completely.

Instructions

Add salt, meringue powder, and water to a bowl. Whisk until smooth and lump-free—the mixture will look frothy on top.

Add all the powdered sugar at once. Using a mixer with a paddle attachment, mix on low until combined, then add vanilla and corn syrup. Increase to medium speed and mix until thick, glossy, and fluffy.

Cover immediately with plastic wrap touching the surface (or a damp towel if using right away). Store in an airtight container if making ahead.

This creates a thicker piping consistency—color and thin as needed for decorating.

If you don’t use all of your frosting and would like to save it for another time, seal it into an airtight container and freeze. It can sit out, covered, at room temperature for a couple days but the water, color, and egg powder base will begin to separate. The contents begin to break down and it’ll become to harder to use over time.
