1 large ripe banana
1/8 teaspoon baking powder
1 pinch ground cinnamon (optional)
2 teaspoons butter, or as needed
1. Mash banana in a bowl using a fork; add eggs, baking powder, and cinnamon and mix batter well.
2. Heat butter in a skillet over medium heat. Spoon batter into the hot butter and cook until bubbles form and the edges are dry, 2 to 3 minutes. Flip and cook until browned on the other side, 2 to 3 minutes. Repeat with remaining batter.
