In a large bowl, whisk together flour, baking powder, baking soda, salt, and cinnamon.
In a separate bowl, mash bananas until smooth. Add almond milk, maple syrup, vanilla extract, and melted coconut oil. Mix well.
Pour the wet ingredients into the dry ingredients and stir until just combined. Avoid overmixing; the batter should be slightly lumpy.
Preheat a non-stick skillet or griddle over medium heat and lightly grease with oil.
Pour ¼ cup of batter per pancake onto the skillet. Cook for 2–3 minutes, or until bubbles form on the surface and the edges appear set.
Flip carefully and cook for another 2–3 minutes until golden brown and cooked through.
Repeat with the remaining batter.
