Preheat the oven to 350°F, 175°C.
In a medium bowl, cream together the butter, white & brown sugar until smooth. Beat in the egg and stir in the vanilla.
Combine the flour and baking soda (separately from the mixture). Stir the flour and baking soda into the creamed mixture and then fold in the chocolate chips. Using two teaspoons drop the mixture onto a baking sheet and press down slightly to flatten. Place on a greased baking sheet about 2 inches apart.
Cook for 10-14 minutes in preheated oven. Remove the cookies from the oven and immediately decorate with Minstrels. Allow to cool for 5 mins before placing them on a wire rack to cool completely.
