These cookies are really chewy and addictive.
1 cup butter, softened
1 cup peanut butter
2 cups packed brown sugar
1 cup white sugar
1/4 cup light corn syrup
1/4 cup water
1 tablespoon and 1 teaspoon vanilla extract
5 cups all-purpose flour
2 teaspoons baking soda
1 teaspoon salt
4 cups chopped semisweet chocolate
Preheat oven to 375 degrees F (190 degrees C).
In a large bowl, cream together the butter, peanut butter, brown sugar, and white sugar until smooth. Beat in the eggs one at a time, then stir in the corn syrup, water, and vanilla. Combine the flour, baking soda, and salt; stir into the peanut butter mixture. Fold in chocolate chunks. Drop by 1/4 cupfuls 3 inches apart onto ungreased baking sheets.
Bake for 12 to 14 minutes in the preheated oven, or until edges are golden. Allow cookies to cool for 1 minute on the cookie sheet before removing to wire racks to cool completely.
