In a large bowl, whisk together flour, protein powder, baking powder, cinnamon, and salt.
In a separate bowl, whisk mashed banana, dairy-free milk, flax egg, vanilla extract, and maple syrup.
Gently fold the wet ingredients into the dry ingredients, stirring until just combined (don’t overmix!).
Heat a non-stick pan or griddle over medium heat and grease lightly with coconut oil or vegan butter.
Pour ¼ cup of batter per pancake onto the pan.
Cook for 2-3 minutes until bubbles appear on the surface, then flip and cook for another 1-2 minutes until golden brown.
Stack the pancakes and drizzle with maple syrup.
Top with fresh fruit, nut butter, coconut yogurt, or crushed nuts for extra flavor and texture.
