Whisk together the flour, baking powder, and salt in a bowl.
Beat the butter and sugar together until fluffy, about 3 minutes. Beat in the egg, vanilla, and almond extract.
Add the dry ingredients and mix on low speed until a smooth dough forms.
Divide the dough in half, flatten into disks, wrap, and chill for 1 hour.
Preheat the oven to 350°F and line two baking sheets with parchment.
Roll one disk at a time to ¼-inch thickness on a lightly floured surface and cut into shapes.
Place 2 inches apart on the sheets and bake for 9–10 minutes, until the edges are just barely golden.
Cool on the pan for 5 minutes before transferring to a wire rack to cool completely before decorating.
