Heat a medium-large nonstick skillet over medium heat.
Melt the coconut oil in the pan.
Add the bananas in a single layer, reducing the heat to medium-low.
Cook for 2 minutes, then flip.
Add the maple syrup and cinnamon, bringing the heat back up to medium.
Cook the bananas for another 2 minutes, then gently stir in the vanilla and sea salt.
Serve hot, over toast, oatmeal, pancakes, ice cream, or as is.
