In a large bowl cream together butter and sugar until fluffy. Then beat in eggs and vanilla.

In a medium bowl whisk together flour, salt and baking powder. Add to the creamed mixture and combine with a wooden spoon.

Move to a lightly floured flat surface and shape into a ball. Wrap in plastic wrap ad refrigerate for 20 minutes.

Remove from fridge and on a lightly floured surface roll dough (1/3 at a time to make it easier) out to 1/8 inch or a little thicker and cut with floured cookie cutters. Place on parchment paper lined baking sheets and bake in 350° pre-heated oven for approximately 10 minutes or until lightly browned. Let cool on wire racks.
