Warned my neighbor not to trust the recipe's 'bake 12 mins' and her brownies came out raw at minute 10
She pulled them at 10 like the box said and the toothpick came out pure batter, so we shoved them back in for 8 more and they finally set. Turns out her oven runs 40 degrees cold, which I caught with a $6 thermometer from the dollar store, not guessing. Anyone else figure out their oven's real temp only after wrecking a whole tray?
