Mix brown sugar, butter, vanilla and egg together. Still in flour, baking soda and ginger.
In small bowl mix the ⅓ cup sugar, ⅛ teaspoon of ginger and cinnamon. Roll a teaspoon of dough into a ball. Roll the ball in the sugar mixture, then place on the cookie sheet. With the bottom of a glass or your fingers, give the dough a little press down, so it's about a ½" thick.
Bake at 375 degrees for 8-10 mins.
