Prepare the Oven and Pan: Preheat the oven to 350°F and position a rack in the center of the oven. Line baking sheets with parchment paper or leave them ungreased.
Make the Cookie Dough: In a mixing bowl with an electric mixer, beat the butter and brown sugar together until light and fluffy. Beat in the egg and vanilla. In another bowl, combine the flour, baking powder, and salt. With the mixer on low speed, blend the dry mixture into the creamed mixture. Stir the ground almonds into the cookie dough.
Refrigerate: Chill the dough for about 20 to 30 minutes.
Roll and Cut: On a floured surface, roll the dough out to a thickness of about 1/8 to 1/4 inch. Cut the dough out with cookie cutters and arrange them on the prepared baking sheets.
Bake: Transfer the baking sheet to the oven and bake for approximately 10 minutes, until the cookies are set. Cool on a rack.
