Mash or blend the base: In a mixing bowl, mash the bananas until smooth. Whisk in the eggs, yogurt (or cottage cheese), and vanilla. For extra-smooth batter, blend everything in a blender.
Add dry ingredients: Stir in the protein powder, oats (or oat flour), baking powder, cinnamon, and salt.
If the batter looks very thick, add milk 1 tablespoon at a time until it’s pourable but not runny.
Rest the batter: Let it sit for 5 minutes. This helps the oats hydrate and gives fluffier pancakes.
Preheat the pan: Heat a nonstick skillet or griddle over medium heat. Add a light layer of butter or oil.
Cook the pancakes: Scoop 1/4 cup batter per pancake.
Cook until bubbles form on top and edges look set, about 2–3 minutes. Flip and cook another 1–2 minutes until golden and cooked through.
Adjust heat as needed: If pancakes brown too fast, lower the heat slightly. Wipe the pan and add more oil between batches if needed.
Serve warm: Top with yogurt, maple syrup, peanut butter, or fruit.
Enjoy immediately.
