How to Make It
Heat a nonstick griddle or nonstick skillet over medium. Stir together eggs, mashed bananas, oats, flax seed meal, apple pie spice, and salt in a bowl until combined. Microwave maple syrup and butter on HIGH in a small microwavable bowl until syrup is warm and butter is melted, about 1 minute; set aside.
Spoon banana batter by 1/4-cupfuls onto hot griddle to make 8 pancakes. (If using a nonstick skillet, cook pancakes in batches; keep cooked pancakes warm in a 200°F oven while making remaining pancakes.) Spread each batter mound into a 4-inch round pancake; cook 2 minutes. Carefully flip pancakes using a spatula; cook 1 minute.
Transfer 2 pancakes to each of 4 plates; top each with 2 tablespoons warm maple syrup mixture. Top evenly with sliced banana.
