yield: ABOUT 6 DOZEN COOKIES cook time: 12 MINUTES PER PAN 2 & 1/2 cups all-purpose flour 2 cups quick-cooking rolled oats 1 teaspoon baking soda 1 teaspoon salt 1 cup unsalted butter, softened 1 cup firmly packed light brown sugar 1/2 cup granulated sugar 1 cup peanut butter, creamy or crunchy** 2 large eggs 2 tablespoons vanilla extract 2 cups semisweet chocolate chips Preheat oven to 350°F. Line baking sheets with silicone liners or parchment paper. Whisk together the flour, oats, baking soda, and salt. Set aside. Using an electric mixer on medium speed, beat the butter, brown sugar, and sugar until light and creamy. Add the peanut butter, and mix until combined. Add the eggs and vanilla, and mix until combined. Reduce mixer speed to low. Gradually add the flour mixture, mixing just until combined. Stir in the chocolate chips. Drop the dough by tablespoonfuls onto the prepared pans. Bake 10 to 12 minutes, or until the cookies are lightly browned but the centers are still soft. (Place the cookie dough in refrigerator between baking batches.) Cool the cookies on pan for 5 minutes. Then, transfer the cookies to wire racks to cool completely.
