• Preheat oven to 350 degrees Fahrenheit (177 degrees Celsius).
• Grease a 9x5” loaf pan, set aside.

Brown the Butter

• Cut butter into ½ “cubes.
• Put butter in a thick-bottomed pan (preferably in an even layer).
• Cook over medium heat, stirring occasionally,
• First, the butter will melt.
• Then, it will begin to foam on top and start bubbling.
• Next, it will start turning light brown with light brown flecks.
• Then, it will start turning a darker brown, amber color. At this point the butter is browned and cooking is complete.
• Transfer it to a large mixing bowl (one you will mix the rest of the ingredients in), let cool to room temperature.

Make the Banana Bread

• Add the bananas to the cooled brown butter and mash the bananas.
• Then add the eggs and vanilla and stir to combine.
• Add granulated sugar and brown sugar and stir until mixture is smooth.
• Add flour, baking powder, baking soda, sea salt and cinnamon and stir until combined.
• At this point you can add up to 1 cup of mix ins like chocolate chips, nuts, etc.
• Evenly spread the batter in the prepared loaf pan.
• Bake on the lowest rack in the preheated oven for 50-60 minutes, or until the top is golden brown and a toothpick inserted in the center of the banana bread comes out with just some moist crumbs. (If the top starts browning too much before the toothpick comes out clean, loosely tent the loaf with aluminum foil).
• Cool in the baking pan on a wire rack for at least 2 hours, or overnight.
• Use a butter knife to release the sides of the bread from the pan if necessary.
• Put the banana bread on a cooling rack and let cool completely.
