Heat 1 teaspoon butter in a skillet over medium high heat.
Once melted, add the bananas in one layer to the skillet and cook for about 2-4 minutes until golden on the bottom.
Flip and cook another 2 minutes.
Add remaining teaspoon of butter to the skillet. Sprinkle bananas with cinnamon and brown sugar, and add vanilla extract and salt if using.
Shake the skillet to coat bananas (or use a spatula to gently toss the bananas in the mixture).
Turn off heat and add rum. Let sit for about 5-10 minutes until a thick sauce forms.
Meanwhile, toast the bread and top each slice with about 2 teaspoons each of peanut butter.
Top peanut butter with banana slices. Enjoy immediately!
*If you aren't interested in using rum, skip it and add an extra 1/8 teaspoon vanilla extract plus a tablespoon of water.*I prefer using bananas that have a smidge of green in them so they hold up best. Very ripe bananas will fall apart when cooking giving you a mushy banana mixture.
