National Cupcake Day is next Friday, Dec. 15. To celebrate, Sprinkles, the "world's first cupcake bakery," is giving away free cupcakes for a year. To enter the giveaway, customers must be a member or sign up for the Sprinkles Perks Program and make a purchase at any Sprinkles bakery nationwide now through Dec. 12. Each visit will count as a different entry. Winners will be contacted on Dec. 14. To make National Cupcake Day even sweeter, the first 50 customers in line at each bakery on Dec. 15 will receive a FREE limited-edition Strawberry Sprinkles Cupcake, loaded with rainbow sprinkles and topped with a cream cheese frosting.
