Preheat oven to 350-degrees.
Cream together the butter, cream cheese, and sugars. Add the egg and vanilla and mix well. Sift dry ingredients together and slowly incorporate them with the wet ingredients.
Use a tablespoon scoop to transfer dough to a cookie sheet. The dough will not spread much as it cooks.
Bake for 10-12 minutes. Leave them on the cookie sheet for a few minutes before moving to a rack to cool.
