Preheat oven to 350F. In a large bowl, mix together the softened butter, vanilla and sugar. In another bowl, add the remaining ingredients. Pour the butter mixture into the flour mixture and mix together well. Dough will be slightly formed with some crumbling. Roll golf size balls in hand and then flatten and place on a greased cookie pan. Sprinkle brown sugar crystals on top. Bake for 8 – 10 minutes. Enjoy!
