2 tablespoons milk (add this at the very end just to make dough smooth and creamy)
2 cups semi-chocolate chips (depending on your preferred chocolate needs)
1. In a large mixing bowl beat butter and peanut butter with an electric mixer on medium to high speed for 30 seconds. Add the granulated sugar, brown sugar, baking soda, and baking powder. Beat until combined, scraping sides of bowl occasionally. Beat in the egg and vanilla until combined. Beat in as much of the flour as you can with the mixer. Stir in any remaining flour. Add milk just enough to make the dough moist and creamy. Add chocolate chips and mix till just incorporated. If necessary, cover and chill dough about 1 hour or until easy to handle.
2. Preheat oven to 375 degrees F. Drop cookies by scooping them out of the bowl with a spoon dropping them in small balls onto your greased cookie sheets (instead of rolling them into balls and sugar and then pressing with a fork). Bake for 7 to 9 minutes or until bottoms are light brown. Transfer to a wire rack and let cool. Makes about 36 cookies.
