Starbucks is making its "secret menu" official — and turning it into a nationwide contest with a cash prize. Why it matters: It's the Seattle-based coffee giant's latest play to win back customers and reverse sliding sales.

For years, t he secret menu has offered twists on fan favorites to completely new creations. Now, you can unearth the secret menu in the “offers” tab of the app. It will include new drink customizations (AKA secret menu drinks) and be updated regularly with new and exciting options.
