The folks at Oreo are finally ready to share the dough… well, sort of.

Earlier this week the popular cookie brand, which is owned by manufacturing giant Nabisco, announced a nationwide search to name the best new flavor for the snack’s creme filling. The famed creme’s latest flavor, the “Firework Oreo,” launched with limited runs in time for the Fourth of July. But we knew you can do better than that concoction— and there’s a $500K prize in store if you nail it.

CASSIUS is happy to cash in—and to make sure the winning flavor isn’t too vanilla. Here’s your chance to vote on which filling you think has the best shot. Check out our categories and pick your faves:
