We just learned what Oreo's mystery flavor actually was (churro). Now it's time for a new sweet treat guessing game. Starbucks is dipping its toe into the mystery flavor contest game. Starbucks launched their own line of coffee creamers this year. And now they're launching a new creamer, but you have to guess what it is.

But there's a catch with this contest ... you don't get to try it before you guess. Confused? I was too. MSN explains -

From Dec. 5-11, fans can tweet their predictions using the hashtags #StarbucksCreamerMysteryFlavor and #giveaway. The first 50 people who get it right will receive a bottle before it hits shelves nationwide in January.

So clearly you don't need to try anything to be able to guess. But that makes it even harder because the possibilities are endless. Even though I would say it's safe to assume it's one of their signature drink flavors considering the existing flavors are caramel, white chocolate and cinnamon dolce creamers.

So tweet your guess and if you win please share the new creamer with me.
