In a food processor, combine the butter and flour and mix until crumbs form. Turn the dough out onto a floured surface and make a well.
To the well add the sugar, baking powder, vanilla, egg, and lemon zest.

Form the dough into a disk and wrap in plastic wrap. Refrigerate for 1 hour.
Preheat your oven to 350 degrees. Line a baking sheet with parchment paper.
Roll the dough out between 2 pieces of parchment paper to about 1/8 inch thickness.

Roll each cookie in granulated sugar and place 1 inch apart on the prepared baking sheet.
Bake for 8-10 minutes or until the bottoms are golden brown.
