Soak oats in buttermilk, overnight, in the refrigerator. In the morning, in a separate bowl, mix eggs, then add butter and raisins or dried fruit. Add to the oatmeal mixture and stir gently.
Mix together the dry ingredients in a small bowl, the flour, baking soda & powder, cinnamon, and salt. Add to the oatmeal mixture and stir until just moistened.
Spoon 1/3 cup onto an oiled griddle or pan, spreading a bit with a spoon or spatula, if needed. Cook until one side is well browned, then turn and finish cooking on the other side.
