Protein pancakes with banana and oats are soft, a little custardy in the middle, and actually filling thanks to oats, egg whites, and Greek yogurt. Blend-and-pour batter makes them weeknight/weekday friendly, with a texture that’s sturdier and less eggy than classic banana-egg pancakes.
Blend the dry ingredients. Add the oats, protein powder, baking powder, salt, and cinnamon to a blender. Blend until the oats turn into a fairly fine flour (no big flakes).
Add the wet ingredients. Break the banana into chunks and add it to the blender with the egg whites, Greek yogurt, 1/4 cup milk, oil or melted butter, maple syrup or honey (if using), and vanilla.
Blend to a thick batter. Blend until completely smooth, stopping to scrape down the sides. Batter should be thicker than standard pancake batter but still pourable; if too thick, blend in milk 1 tablespoon at a time.
Rest the batter briefly. Let the batter sit for 5–10 minutes while you heat the pan.
Heat the pan properly. Set a nonstick skillet or well-seasoned griddle over medium heat. Once hot, brush lightly with butter or oil (a drop of batter should sizzle, not smoke).
Portion small pancakes. Pour about 2 tablespoons of batter per pancake (about 7–8 cm / 3 inches wide).
Cook the first side slowly. Cook 2–3 minutes, until edges look dry and small bubbles appear. If browning before the top sets, lower the heat.
Flip carefully. Slide a thin spatula fully underneath and flip in one motion. Don’t press or fuss after flipping.
Finish cooking. Cook the second side 1–2 minutes, until centers spring back lightly and sides look set (not shiny).
Adjust the batter as you go. If the batter thickens while sitting, stir in a splash of milk to loosen.
Keep them warm. Transfer cooked pancakes to a plate or a low oven (90–100°C / 200°F) while finishing the batch.
Serve. Top with extra Greek yogurt or cottage cheese, banana slices, berries, and/or a small drizzle of maple syrup; add nut butter if desired.
