PREHEAT oven to 375° F.
In a mixer with a paddle attachment, combine the sugars, butter and peanut butter. Beat until light and fluffy, about 3 minutes. Add the eggs, one at a time, beating after each addition. Sift together the flour, the baking soda and the salt and add to the dough. Dough should be stiff enough to shape with your hands. Make 1-inch balls and place on a lightly greased cookie sheet. Gently press thumb into the balls to flatten the cookies slightly and make an indentation in the center of the cookie. Press 3 or 4 chocolate chips into the indentation.
COMBINE flour, baking soda and salt in small bowl. Beat butter, granulated sugar, brown sugar and vanilla extract in large mixer bowl until creamy. Add eggs, one at a time, beating well after each addition. Gradually beat in flour mixture. Stir in morsels and nuts. Drop by rounded tablespoon onto ungreased baking sheets.
BAKE for 9 to 11 minutes or until golden brown. **Joe's Hint** - be sure to take them out a little early so that they're chewy!
Cool on baking sheets for 2 minutes; remove to wire racks to cool completely.
