Preheat the oven to 325 degrees. Cream together the butter, peanut butter, and both sugars; beat in eggs. Add flour (use a spoon to place flour in your measuring cup--this ensures you don't use too much flour) and baking soda to creamed mixture and beat well.

Stir in chocolate chips. Roll dough into 1 inch balls, then roll them in granulated sugar and place an inch apart on an ungreased cookie sheet. (I like to use a layer of parchment paper.) Use two fingers to press the cookies down slightly, or use a fork. Bake 12-15 minutes, or until lightly browned. Do not overbake! Cool slightly before removing from pan to cooling rack. Makes 2-3 dozen.
