In your high-speed blender, combine the ripe banana, oats, egg, milk, sea salt, vanilla extract, baking powder, and cinnamon. Blend until smooth. Adjust consistency with more milk if needed.
Place your non-stick skillet or griddle over medium heat. Warm it for a few minutes and lightly grease it.
Pour about 1/4 cup of batter onto the skillet for each pancake. Cook until bubbles form and edges look set, about 2-3 minutes.
Carefully flip pancakes and cook for another 2-3 minutes until golden brown. Repeat with remaining batter, greasing as needed.
Serve warm, topped with maple syrup, fresh fruit, or chopped nuts. Enjoy your wholesome breakfast!
