In a mixing bowl, add the flour, baking powder, and salt, whisk to combine and set aside.

In another mixing bowl, cream together the butter and sugar and mix until creamy, then mix in the egg and vanilla.

Slowly add the flour mixture to the wet mixture and mix in until combined.

Cover the dough and place in the fridge for at least 4 hours or overnight.

When ready to bake, preheat your oven to 190 C (375 F) and line a baking sheet with parchment paper.

Lightly flour your work surface, and roll out the dough to 1/4 inch thick. Cut into shapes either freehand, with seasonal shaped cutters, or just round cutters, totally up to you.

Place cookies on on the baking sheet 1 inch apart and bake for 9-11 minutes, the key is white cookies with very little browning on the edges.

Remove from baking sheet to a wire rack and allow to cool completely. Decorate the cookies as desired.
