This recipe for deliciously chewy cookies comes from Martha Lively of Wilton, Maine.
Preheat oven to 375 degrees. In a medium bowl, whisk together flour, baking soda, and salt; set aside. With an electric mixer, cream butter and sugars until light and fluffy.
Add eggs and vanilla; beat until combined, scraping down sides of bowl as needed. Add flour mixture; beat until just combined. Add oats, raisins, and chocolate chips; beat until just combined.
Drop 32 heaping tablespoons of batter, about 1 1/2 inches apart, onto baking sheets. Bake, rotating sheets halfway through, until cookies have spread and are golden brown and soft to the touch, 10 to 12 minutes. Cool 5 minutes on sheets; transfer to a wire rack to cool completely.
If you prefer a crispier texture, bake the cookies at 350 degrees for 16 to 20 minutes.
