Miss Rosa Lee's Oatmeal Cookies

In a large mixing bowl, beat oil, butter and brown and white sugars with an electric mixer on medium speed until the mixture is light and fluffy. Add the eggs, one at a time, beating well after each addition. Beat in vanilla then cinnamon, baking soda, and baking powder; beat until just combined. Add the flour and rolled oats, beating until just combined. Stir in the nuts and raisins, if you like. Drop dough by rounded tablespoonfuls on ungreased baking sheets.

Bake in a 350° oven for 8 to 10 minutes or until golden brown. Cool on sheets for 5 minutes; transfer to wire racks to cool completely.
