Land O Lakes offers a recipe for the "best ever" oatmeal cookies on its website, LandOLakes.com. The recipe makes four dozen cookies and requires 45 minutes of prep time.
To make the cookies, preheat the oven to 375 degrees, and combine 3 cups quick-cooking oats, 2 cups packed brown sugar, 1 cup softened butter, 2 teaspoons vanilla, 1 teaspoon baking soda and 1/2 teaspoon salt in a bowl. Beat the ingredients using a hand mixer on low speed until combined well, and then add 1 1/2 cups of flour.
Drop teaspoonfuls of the dough onto a lightly greased cookie sheet, and bake the cookies for eight to 12 minutes or until the edges brown.
