- 1 cup margarine, softened
 - 1 cup peanut butter
 - 1 cup white sugar
 - 1 cup packed brown sugar
 - 2 eggs
 - 2 cups unbleached all-purpose flour
 - 1 teaspoon baking soda
 - 2 cups semisweet chocolate chips
 
- Preheat oven to 325 degrees F (165 degrees C).
 - In a large bowl, cream together the margarine, peanut butter, white sugar, and brown sugar until smooth. Beat in the eggs one at a time, mixing well after each. Combine the flour and baking soda; stir into the peanut butter mixture. Mix in chocolate chips. Drop by heaping spoonfuls onto ungreased cookie sheets.
 - Bake for 12 to 15 minutes in the preheated oven, or until lightly browned at the edges. Allow cookies to cool on the cookie sheets for a minute before removing to wire racks to cool completely.
