In a large bowl, combine the oats and buttermilk, and let the mixture stand for about 15 minutes or longer to soften.
Add the remaining wet ingredients, blending them well.
In a small bowl, combine all the dry ingredients. Stir them into the wet ingredients, mixing them until the batter is fairly smooth. Add more milk if the batter is too thick.
For each pancake, place about 3 tablespoons batter on a hot, lightly greased griddle. Flip the pancakes when their undersides are golden brown and the tops begin to bubble.
