This Lucky Shamrock Shake will remind you of a boozy version from that fast food place, only way better! It has vanilla ice cream, Lucky Charms cereal, fresh mint, and crème de menthe! It’s creamy, minty, and so delicious! Plus, shamrocks are lucky, so adding Lucky Charms cereal seems like a no-brainer! The marshmallow-y cereal flavor gives this adult version of a shamrock shake a touch of whimsy (and who doesn’t love whimsy?).
