In a medium bowl, whisk together the flour, sugar, baking powder, and salt. Set aside.
In another bowl, combine the milk, egg, and melted butter. Mix well.
Pour the wet ingredients into the dry ingredients and stir until just combined. Do not overmix; a few lumps are okay.
In a skillet over medium heat, melt a little butter and add the sliced bananas. Sprinkle them with brown sugar and cinnamon.
Cook for about 2-3 minutes until the bananas are caramelized and golden brown, then carefully flip them to cook the other side for an additional minute. Remove from heat.
In the same skillet, ladle about 1/4 cup of pancake batter onto the heated surface. Add a few pieces of the caramelized bananas on top of the batter before flipping.
Cook for 2-3 minutes on one side until bubbles form, then flip and cook for another 1-2 minutes until golden brown.
Repeat with the remaining batter and caramelized bananas.
Serve warm, topped with additional caramelized bananas, a drizzle of maple syrup, and chopped nuts if desired.
Notes
Serve warm with maple syrup and optional chopped nuts.
