In a medium sauce pan over medium heat melt all the butter. Once the butter starts to simmer, then boil, keep an eye on it. As you hear the popping sounds start to slow down, your butter is almost done. Once the bubbling butter becomes silent, pull your butter off of the heat. Stir, scraping the bottom of the pan to get all the browned bits. Pour the browned butter into a small bowl to cool off a bit.
In a separate bowl peel and mash the bananas
In a standing mixer add the sugar and butter, mix fully.
Add the eggs and mix until just combined.
Pour in the vanilla extract and bananas, mix until combined.
Add flour, salt and baking soda to the standing mixer and mix until the batter all comes together.
Pour the batter into two light metal, greased bread pans.
Place in the oven and bake for 30 minutes. After 30 minutes place tinfoil on top of the bread and bake for another 20 minutes. Check the bread at this point to see if it is fully cooked throughout. You can poke a fork or toothpick in the middle. If it is, remove the bread. If not, bake for another 10 minutes.
Once the bread is done, remove and allow it to cool for 15 minutes before enjoying.
