Plain yogurt is the ultimate food disguise. It looks innocent, but it packs a protein punch and a wicked tang. Swap oil one-for-one with plain Greek yogurt, and your brownies will turn out ridiculously moist.
Fun fact: yogurt is basically milk that went to college and got a degree in being sour. Use full-fat yogurt for the fudgiest results. Your brownies will thank you by not crumbling into a sad, dusty mess.
Warning: Do not use fruit-flavored yogurt unless you want “blueberry-swirl brownies.” That’s a different party, and you weren’t invited.
