Many moons ago, we suffered an unfortunate loss of one favorite childhood cereal–Oreo O’s. The only place left to find it is South Korea (y tho?).

Thankfully, we figured out how to recreate this lost legend. And it’s even better than the original. The best part about Oreo cookies is dipping them in milk, and now you can delight in this perfect pairing whenever you please. You’ll never settle for just dunking again.
