In a large bowl, combine the flours, sugar, baking powder and salt. In a second bowl, combine the egg, milk, bananas and vanilla; stir into dry ingredients just until moistened.
Pour batter by 1/4 cupfuls onto a hot griddle coated with cooking spray; sprinkle with blueberries. Turn when bubbles form on top; cook until second side is golden brown. If desired, serve with syrup and sliced bananas. Freeze option: Freeze cooled pancakes between layers of waxed paper in a resealable freezer container. To use, place pancakes on an ungreased baking sheet, cover with foil, and reheat in a preheated 375° oven 6-10 minutes. Or, place a stack of 3 pancakes on a microwave-safe plate and microwave on high until heated through, 1-1/4 to 1-1/2 minutes.
Editor's Note: If using frozen blueberries, do not thaw.
If using frozen blueberries, use without thawing to avoid discoloring the batter.
