Beginning May 17, a brand-new Mickey Mouse celebration cake can be ordered at any Walt Disney World Resort owned and operated table-service restaurant. The cake is available in either chocolate or white chocolate, and can be decorated with a special message of "Happy Birthday" or "Congratulations" on the chocolate ears. Each cake serves 4 to 6 guests, and costs $35 plus tax and gratuity. Celebration cakes can be added to a new or existing dining reservation starting May 17 by calling 407-WDW-DINE or by inquiring in person at a Walt Disney World Resort concierge desk or restaurant podium. Booking ahead is encouraged, as same-day quantities are limited.
