Mash the banana: In a medium bowl, mash the ripe banana until mostly smooth.
Add wet ingredients: Stir in the cottage cheese, eggs, vanilla, and sweetener (if using). Mix until combined.
Some small curds are fine.
Whisk in dry ingredients: Add flour, baking powder, cinnamon, and a pinch of salt. Stir gently until just combined. Do not overmix.
Rest the batter: Let the batter sit for 3–5 minutes.
This helps the flour hydrate and the pancakes puff.
Preheat the pan: Warm a nonstick skillet or griddle over medium heat. Lightly coat with butter or oil.
Portion and cook: Scoop 1/4-cup portions onto the pan. Cook 2–3 minutes, until bubbles form on top and edges look set.
Flip and finish: Flip gently and cook 1–2 minutes more until golden and cooked through.
Serve warm: Top with sliced bananas, berries, a drizzle of maple syrup, or a dollop of yogurt.
