Preheat oven to 375°F.
Combine oats, flour, brown sugar, raisins, baking soda, baking powder, salt and cinnamon in a large bowl; set aside.
Whisk butter, oil, corn syrup, egg and vanilla in a small bowl until thoroughly combined. Add flour mixture; stir until blended. (Dough will be stiff)
Drop dough by rounded tablespoons (or use a small cookie scoop) onto greased baking sheets.
Bake 7 to 10 minutes or until edges are lightly browned. (Cookies may appear underbaked in center, but will firm up on cooling. Don’t overbake or cookies will be very hard.)
Cool on baking sheet 1 minute; remove to cool on wire racks.
