2 cups mashed bananas (about 3 large ripe bananas)
1 teaspoon vanilla extract
Directions
Preheat the oven to 350 F and grease a 9x5-inch loaf pan with nonstick spray.
Melt the butter in a frying pan on medium-low, then continue to cook, stirring occasionally, for about 5 minutes, or until the butter becomes brown in color and smells nutty. Remove it from heat at that point.
Combine the flour, baking soda, salt, cinnamon, and nutmeg in a bowl.
Mix the sugar with the browned butter.
Beat the eggs, sour cream, bananas, and vanilla into the butter/sugar mixture.
Beat the wet ingredients together with the dry ones until just combined.
Pour the batter into the prepared loaf pan and bake for 55 to 60 minutes, or until a toothpick inserted into the center of the loaf comes out clean.
