In a large skillet, melt the butter over medium heat.
Once the butter is melted and bubbling, add the sliced bananas to the skillet in a single layer.
Cook the bananas for about 2-3 minutes on one side until they start to turn golden brown.
Carefully flip the bananas over and sprinkle the brown sugar, cinnamon, vanilla extract, and a pinch of salt over them.
Cook for an additional 2-3 minutes, gently stirring to coat the bananas in the cinnamon sugar mixture.
Remove from heat and let cool slightly before serving.
If desired, top with chopped nuts or shredded coconut before serving.
