For shapes- roll out chilled dough ½ inch thick on a well floured surface. Flour rolling pin and cut out to prevent sticking. Cut out desired shapes and place on parchment lined baking sheet. Bake in preheated oven for 10-12 minutes. Do not overbake. Cool for a few minutes and transfer to wire rack to cool.
Shapes will spread from the baking powder. To define the shape used after the cookie has cooled, place cookie cutter on top of cookie and firmly press all the way down, removing any access cookie for the edges.
