From Fat Girl Trapped in a Skinny Body... Browning brings out the richness of the butter. Go ahead and try a little spoonful from the pan, see, now you know what I'm talking about. The nutty, salty, sweet, milky flavors are all enhance. The brown butter and the brown sugar really give the loaf a depth of flavor that can't be achieved form just using regular butter or white sugar. It is worth the effort of using 1 extra pan to make the brown butter, it is TOTALLY worth it! The 'crust' has a perfect slight crunch, and the inside, wow, I literally can't stop eating it. It isn't overly sweet either. It is sweet yes, but not like a cake. But it is buttery like a cake, PERFECT!
