In a large bowl, combine the two types of flour, oats, baking powder, and cinnamon.

In a separate bowl, mash the banana with a fork. Add the milk, egg, and vanilla to the mashed banana and stir.

Pour the wet ingredients into the dry ingredients. Mix with a spoon. (It is fine if the batter is chunky.) Add the blueberries and pecans to the batter and stir.

Heat a frying pan or griddle to medium high heat. Spray the pan with cooking spray or coat with butter. Pour the batter onto the hot pan in pancake circles.

Heat on one side until tiny bubbles start to form in the pancake (about 3-4 minutes). (If the pancake gets too dark, turn the heat down slightly.) Flip the pancake and cook for 3-4 minutes on the other side. Top with banana slices, a sprinkle of cinnamon and sugar, or a drizzle of syrup
