In a small bowl, whisk together flour, sugar, baking powder, and salt; set aside.
In a medium bowl, whisk together milk, butter and egg. Add dry ingredients to milk mixture and whisk until just combined.
Gently fold in mashed banana and nuts, careful not to over-mix. Let batter sit for 5 minutes.
Heat a large nonstick skillet or griddle over medium heat. Using a paper towel, spread some butter onto the skillet. Wipe off any excess with the other side of the towel.
Spoon ¼ cup of the mixture onto preheated skillet and let cook for 1-2 minutes, or until surface of pancakes have some bubbles and a few have burst.
Flip carefully with a thin spatula, and cook until browned on the underside, 1 to 2 minutes more.
Serve hot and enjoy! Top with a few sliced bananas, a sprinkle of nuts, and a drizzle of maple syrup to enjoy more banana nut goodness!
