Preheat the oven to 400.

Use an electric mixer to cream the butter, sugar, egg and vanilla extract in a large bowl.

Add in the rest of the ingredients and beat until completely mixed.

Lay out a large piece of plastic wrap. Scrape all of the dough out of the bowl onto the plastic wrap and then roll it into a log. Make it about 2 1/2 inches wide.

Wrap the dough completely with the plastic wrap and place in the refrigerator until it is firm. At least 20 minutes or you can leave it in there overnight.

Once the dough is firm, slice it into cookies (about 1/8 of an inch thick) and place them on ungreased cookie sheets about 1 inch apart.

Bake for 8 to 10 minutes or until they are lightly browned around the edges.

Allow cookies to cool completely.
