Make the pancake batter by combining the flours, sugar, cinnamon, baking powder, baking soda, salt, and nutmeg in a large bowl, stirring well to combine.
Combine yogurt, mashed banana, eggs, butter, and vanilla in a small bowl, mix thoroughly.
Add the flour mixture to the yogurt mixture, stirring until smooth.
Cook the pancakes by heating a griddle or large skillet coated with cooking spray over medium heat.
Pour about ¼ cup of batter per pancake onto the hot griddle or large skillet and cook for 2 minutes or until the tops are covered with bubbles and the edges look cooked.
Carefully flip pancakes and cook for 2 more minutes, or until bottoms are lightly browned.
Serve immediately, topped with butter, freshly sliced banana, and warm maple syrup. Enjoy.
