Start by warming a skillet or griddle over medium-low heat. In a large bowl mix together the flour, baking powder, white sugar, salt, cinnamon, brown sugar, and nutmeg. Add the milk and vanilla extract and mix until the dough is thick and smooth.
Combine the mashed bananas and melted butter with the dry ingredients, and mix thoroughly so that the batter is smooth and evenly distributed.
Lightly spray the skillet with cooking spray, then add 1/3 cup batter to the center of the pan. Cook for 1 to 3 minutes, until bubbles appear on the surface. Fry until golden brown both sides.
Continue this process with the remaining batter, making about 8 pancakes total.
Whisk maple syrup, powdered sugar, and vanilla extract together in a bowl until smooth to prepare the vanilla maple glaze. Drizzle this glaze over the warm pancakes right before serving.
