I like this recipe from the Quaker Oats box
Vanishing Oatmeal Cookies
1/2 cup (1 stick) plus 6 tablespoons butter, softened
3/4 cup firmly packed brown sugar
1/2 cup granulated sugar
1 teaspoon vanilla
1-1/2 cups all-purpose flour
1 teaspoon baking soda
1 teaspoon ground cinnamon
1/2 teaspoon salt (optional)
3 cups (quick or old fashioned, uncooked)
1 cup raisins
Heat oven to 350°F. In large bowl, beat butter and sugars on medium speed of electric mixer until creamy. Add eggs and vanilla; beat well. Add combined flour, baking soda, cinnamon and salt; mix well. Add oats and raisins; mix well.
Drop dough by rounded tablespoonfuls onto ungreased cookie sheets.
Bake 8 to 10 minutes or until light golden brown. Cool 1 minute on cookie sheets; remove to wire rack. Cool completely. Store tightly covered.
