These cookies are very chewy and the raisins help keep them soft!
In a separate bowl, combine the flour, soda, powder, salt, and cinnamon until combined. Gradually add the flour mixture to the butter/sugar and mix until just combined. Add the oatmeal and raisins and mix until combined.
Drop dough onto prepared pans by 1 1/2 tablespoons. (I use a medium cookie scoop). Bake for 10-12 minutes, until cookies the edges are browned and the centers are set.
