Method

1. In a bowl, cream butter and sugar with a mixer until smooth (at least 3 minutes).
2. Beat in vanilla and egg.
3. In a separate bowl, combine baking powder, salt, and flour.
4. Add dry ingredients to the wet ingredients a little at a time. The dough will be very stiff. If it becomes too stiff for your mixer, turn out the dough onto a countertop surface.
5. Wet your hands and finish off kneading the dough by hand (DO NOT CHILL THE DOUGH).
6. Divide into workable batches, roll out onto a floured surface, and cut (You want these cookies to be on the thicker side, roughly 7-8mm thick).
7. Bake at 180°C for 6-8 minutes.
8. Let cookies cool on the sheet until firm enough to transfer to a cooling rack.
