In a medium bowl, beat the eggs lightly. Mix in the mashed banana and baking powder until well combined.
Heat a nonstick skillet or griddle over medium heat. Spray with nonstick cooking spray.
For each pancake, pour about 1/4 cup of the batter onto the hot surface. Sprinkle some chocolate chips over the top of each pancake.
Cook for 2-3 minutes per side, flipping when the edges look dry and the bottom is lightly golden.
Serve the pancakes warm, topped with more chocolate chips, butter, maple syrup, or your favorite toppings.
