In a bowl, combine flours, oats, sugar, baking powder, baking soda, salt and cinnamon. Combine buttermilk, eggs and oil; stir into dry ingredients just until blended. Fold in blueberries if desired.
Combine topping ingredients; sprinkle about 1 teaspoon for each pancake onto a lightly greased hot griddle. Pour 1/4 cup of batter over topping; immediately sprinkle with another teaspoonful of topping. Turn when bubbles form on top of pancake; cook until second side is golden brown.
