Blend the batter: Add bananas, eggs, oats, milk, maple syrup (if using), vanilla, baking powder, cinnamon, and salt to a blender.
Blend until mostly smooth with a little texture from the oats, about 20–30 seconds. Let the batter sit for 5 minutes to thicken.
Heat the pan: Warm a nonstick skillet or griddle over medium heat. Lightly grease with butter or oil.
You want the surface hot but not smoking.
Portion the pancakes: Pour about 1/4 cup batter per pancake. Leave space between them so you can flip easily.
Cook until set: Cook 2–3 minutes, until small bubbles form and the edges look set. The underside should be golden brown.
Flip gently: Slide a thin spatula underneath and flip.
Cook another 1–2 minutes, until the center feels springy and cooked through.
Adjust heat as needed: If pancakes brown too fast, lower the heat slightly. If they take too long, increase the heat a touch.
Serve warm: Top with banana slices, berries, peanut butter, or a drizzle of maple syrup. Enjoy right away.
