Heat oven to 325. Lightly grease two 17x14 inch cookies sheets. In a large bowl of electric mixer, beat butter, sugars, egg and vanilla at medium-high speed until fluffy. Reduce mixer speed to low, add flour and oatmeal, increase mixer speed gradually and beat just until blended. Stir in raisins and nuts. Drop heaping tablespoonfuls of dough 6 cm apart onto prepared sheets. Bake 1 sheet at a time 17 minutes or until edges of cookies are lightly browned and tops look dry. Cook on sheet on wire rack 5 minutes. Remove to rack to cool completely. ----
