Preheat oven to 350 degrees. Sift together flour, baking powder, baking soda, salt, and cinnamon; set aside.
In a medium bowl, cream butter, oil, brown sugar, white sugar, eggs and vanilla. Gradually stir in the dry ingredients until well blended. Mix in oatmeal and raisins. Drop 2 teaspoon measurement onto ungreased cookie sheets. (I use parchment paper on my cookie sheets.).
Bake for 12-14 minutes in preheated oven until edges are golden. Let set on cookie sheet for a few minutes before transferring to a rack to cool completely.
