But they鈥檙e not giving everything away, because the filling is still the classic white, and the black sandwich cookies are also the same鈥 but supposedly the mysterious release has a 鈥fruity鈥 taste and smell (we鈥檙e not revealing anything!). Once you grab your Mystery OREOs and have a taste test, you can visit www.OREOmystery.com for additional sweepstakes information and official rules.

And that鈥檚 not the only stuff coming out of the OREO Wonder Vault. The Junk Food Aisle is reporting that there will be two more new OREO flavors, and choco-hazelnut fans are going to love one of them.

It seems OREO will be releasing a Chocolate Hazelnut flavor, which will be a golden cookie with a creamy chocolate-y filling, and OMG.

And that鈥檚 not all 鈥 the brand is also rumored to be releasing a Hot & Spicy Cinnamon OREO flavor soon too, with the classic black cookie stuffed with a Red Hot-inspired crimson creme filling.

The brand has yet to confirm these two new flavors, but we鈥檙e already waiting in line at the grocery store to snag 鈥檈m.
