"So get this- I replaced the peanut butter caramel with, wait for it...NUTELLA! I probably didn't put enough Nutella in, so you were only able to faintly taste it in the brownies. I was too lazy to measure out one cup of it. I followed the advice of several of the other members here by replacing the Nuscavado (or whatever it is) sugar with light brown sugar; corn syrup with agave nectar; and ditched the espresso powder. I also used half a cup less sugar- I thought a cup and a half of it was way too much (1 cup was too much as well, but meh). I baked it for about 40 minutes and they came out super rich and fudgey! "
