This is one of those awesome treats that doubles as breakfast (oats and banana) and dessert (chocolate) with a special ingredient that ties them both together (thanks peanut butter!). Whenever I can I like to brown the butter I use in recipes to give a depth of flavor and make my kitchen smell awesome in the process. The caramel-y and nutty notes of the browned butter are absorbed nicely by the oats and these bars don't end up feeling too healthy that way. It's always a bonus when you can…
