Position racks in the upper and lower thirds of the oven; preheat to 350 degrees F. Whisk the flour, baking powder and salt in a medium bowl.
Beat the butter, granulated sugar and lemon zest in a large bowl with a mixer on medium-high speed until fluffy, about 3 minutes. Beat in the egg and both extracts. Reduce the mixer speed to low and beat in the flour mixture until just combined.
Fill a cookie press with the dough according to the manufacturer?s directions; press the dough 1 1/2 inches apart onto unlined baking sheets. Decorate with sanding sugar and/or nonpareils.
Bake, switching the pans halfway through, until the cookies are golden around the edges, 14 to 17 minutes. Let cool 5 minutes on the pans, then transfer to racks to cool completely.
