Once bread is removed from oven, let cool in pan for 10 minutes. If you would like to brush melted butter onto your loaf, do it now while the loaf is still warm. After 10 minutes, remove bread from pan, peel off parchment, and let bread cool completely on wire rack for a few hours. (This will be an extreme test of willpower, as your entire kitchen will smell like delicious chocolate. Now is the time to dig into that extra chocolate that I know you have to satisfy your craving while you wait for this to cool!)
