Greetings, Hannah! Welcome to planDisney!
Although subject to change, I checked the menus for
The Plaza Restaurant and the
Plaza Ice Cream Parlor located at Magic Kingdom Park and although they have some great ice cream options available, the Minnie Mouse Kitchen Sink is not currently offered.
However, if you don't mind heading over to
Disney's BoardWalk,
Boardwalk Ice Cream currently has Mickey's Kitchen Sink Sundae on its menu, described as follows:
Hand-scooped Vanilla and Chocolate Ice Cream topped with Hot Fudge, Caramel, Marshmallow Topping, an Ice Cream Cookie Sandwich with Sprinkles, Cream, White and Dark Chocolate Curls, and a Cherry. Served in a souvenir Mickey Kitchen Sink.Finally, there is a kitchen sink sundae currently being served at
Beaches & Cream Soda Shop, located at
Disney's Beach Club Resort. However, this sundae is literally served in a mini kitchen sink and does not have the Mickey Kitchen Sink souvenir to take home with you. This is the option I will be enjoying with my family very soon!
Hannah, I hope you find this information helpful and are able to enjoy a Mickey Kitchen Sink on your next Walt Disney World vacation!
