Buttery, soft Christmas butter cookies with glossy royal icing. Cute, cozy, and easy to decorate for cookie exchanges, gifting, or an Insta-worthy holiday tray.
In a stand mixer or with a hand mixer, cream butter, sugar, and salt until light and fluffy. Add the egg and vanilla, then mix to combine.
Mix in flour until just incorporated. Roll the dough into a disc, cover, and chill for at least 1 hour.
On a floured surface, roll dough to ⅛ inch. Cut tree shapes with a cookie cutter and rectangles with a knife.
Place on a parchment-lined baking sheet and bake at 350°F for 10-12 minutes, until edges just turn golden. Cool completely.
Beat egg whites and confectioners’ sugar until glossy. Divide, tint red and green, and keep covered.
Transfer icing to piping bags, decorate cookies, and let dry 6-8 hours or overnight.
• Chill the dough for at least an hour for best shape.
