Mash the bananas: Peel and place the bananas in a large bowl.
Mash with a fork until mostly smooth with a few small lumps.
Whisk in the wet ingredients: Add the egg, milk, vanilla, and melted butter or oil. Whisk until well combined.
Combine the dry ingredients: In a separate bowl, mix the flour, baking powder, sugar (if using), cinnamon, and salt.
Make the batter: Add the dry ingredients to the wet mixture. Stir gently until just combined.
It’s okay if it’s a little lumpy—overmixing makes pancakes tough.
Rest the batter (optional but helpful): Let the batter sit for 5 minutes. This allows the baking powder to activate and the flour to hydrate, leading to fluffier pancakes.
Heat the pan: Warm a nonstick skillet or griddle over medium heat. Lightly grease with butter or oil.
Cook the pancakes: Pour about 1/4 cup of batter per pancake onto the hot surface.
If using add-ins like chocolate chips or nuts, sprinkle them on now.
Flip at the right time: Cook until bubbles form on the surface and the edges look set, 2–3 minutes. Flip and cook another 1–2 minutes, until golden and cooked through.
Adjust heat as needed: If pancakes are browning too fast, lower the heat slightly. Each stove is different.
Serve warm: Stack on plates and top with butter, maple syrup, and your favorite extras.
