Place a nonstick or cast iron skillet or griddle over medium heat. (I prefer nonstick.) Add a small slice of butter or oil.: You will hear the faint hiss as the pan warms, and a tiny shimmer appears on the surface when it is ready, which tells you it can brown the pancakes gently. I prefer a nonstick pan because these pancakes are fragile and the nonstick surface makes flipping easier, but a well seasoned cast iron also works and gives excellent color. If the pan is too cool the batter will spread too thin without browning, while too hot will char the edges before the center sets. Avoid crowding the pan so each pancake has room and cooks evenly.
Mash the banana with a fork in a medium bowl. Crack the eggs into the same bowl and stir together. The batter will be very runny.: The fat will sizzle softly when it hits a hot pan, releasing a comforting scent that signals the pan is ready for batter. Use just enough to coat the surface, spreading it with a spatula so there is a thin, even sheen, which helps create a golden rim on the pancakes. Too much fat results in greasy pancakes, while too little can make them stick and tear when you flip. If you notice the fat smoking, lower the heat slightly and wipe excess away.
Spread the butter or oil with a spatula to coat the bottom of the pan. Place 1 tablespoon batter into the pan to make small pancakes. Cook until the edges start to set and the bottoms are lightly browned, about 1 minute.: As you mash the banana , its aroma will grow sweeter and the texture will turn silky; aim for very few lumps for the smoothest batter. The mashed fruit provides both flavor and moisture, so mash thoroughly until it reaches a spreadable consistency. A common misstep is leaving large chunks, which can cause uneven cooking and dense spots. If your fruit is overly soft and watery, drain briefly on a paper towel to avoid a batter that is too loose.
Flip carefully and cook for an additional minute. (These are delicate so try to get your spatula halfway under the pancake, then carefully turn over.): When you introduce the egg to the mashed fruit, you will see the mixture become more uniform and slightly glossy, which signals cohesion. Stir until blended; the batter will be very runny, but that is expected. This viscosity helps create the custardy interior. Overmixing is not a concern here, but under mixing can leave streaks of uncooked egg. If the batter separates, whisk vigorously to recombine before cooking.
Remove from pan—the pancakes will be very soft and tender—and serve with any desired toppings.: Running a thin layer across the surface creates a uniform contact point so each pancake browns evenly. The fat should gleam without pooling. If you see pooled fat, tilt the pan and blot the excess with a paper towel. Uneven coating can cause some pancakes to brown too quickly while others remain pale, so take a few seconds to ensure an even film.
Place 1 tablespoon batter into the pan to make small pancakes: The spooned batter will spread slightly and settle, forming small round disks that cook quickly. Look for tiny bubbles at the edges and a change in surface from glossy to more matte, these cues tell you the bottom is setting. Using a tablespoon ensures uniform sizes that fit small hands. Pouring too much batter makes them harder to flip and more likely to break, while too little may result in pancakes that overcook before the center is cooked through.
Cook until the edges start to set and the bottoms are lightly browned, about 1 minute: Watch the edges for a subtle firming and the bottom for a gentle golden color, these signs indicate the pancake is ready to flip. You will hear a faint quiet as steam escapes, and the surface will shift from glossy to more textured. If you wait too long you risk overly browned bottoms and a center that becomes dry, while flipping too soon leaves the pancake undercooked. Mistaking color under bright lights can happen, so gently lift an edge to peek at the bottom.
Flip carefully and cook for an additional minute: A soft sound and a slight puff when you flip indicate the interior is set but tender. Slide your spatula about halfway under the pancake so you support it while turning, this reduces tearing. After flipping you want a short final cook to finish the center without drying it; listen for gentle sizzling and watch for an even light brown. Rushing the flip or using too small a spatula are common mistakes that can break the pancake.
Remove from pan—the pancakes will be very soft and tender—and serve with any desired toppings: When you transfer them, notice the warm sweet aroma and the delicate spring when you touch the center. These pancakes are best enjoyed right away, with toppings like applesauce or yogurt that add moisture and familiar flavors for small eaters. If you plan to store them, cool fully on a rack before refrigerating to prevent sogginess. A typical error is stacking them hot which traps steam and makes them soggy, so always cool briefly before containment.
