Preheat oven to 350°F. In a medium size bowl, combine the peanut butter, sugars and egg. Stir to combine. Add the chocolate chips and stir again. Using a tiny 1/2 teaspoon measuring spoon, drop the batter onto a large baking sheet. 36 cookies fit onto each of my cookie sheets. Bake the bite-size cookies for about 8 minutes or until lightly browned. If you prefer crunchy cookies, bake an additional minute or two. Remove from the oven and cool on wire racks immediately. Enjoy!
