The flavor is called "Firework," and includes creme filled with "popping candy" -- which means unofficial Pop Rocks.
The cookies, which were first announced back in February, are available in select stores starting today.
Oreo also announced a social media contest as they search for their next flavor idea. Today through July 14, you can submit flavor ideas on Instagram and Twitter using the hashtags #MyOreoCreation and #Contest.
Oreo said the winner will receive “$500K and VIP OREO access to upcoming releases and top-secret prototypes.”
"Fan voting" will decide the winner.
