Welcome to Disney Parks Moms Panel, Susan!
When I get a craving for a taste that's only available in Walt Disney World, nothing else will do. That chocolate cake on the menu at
Riverside Mill Food Court at Disney's Port Orleans Resort-Riverside is delicious, so I see why you are in search of more.
On Disney World.com, I entered "
triple chocolate cake" into the searchbar, finding a few chocolate cakes that are not identical, but might fill the bill of your husband's craving. Magic Kingdom's Cosmic Ray's Starlight Cafe offers triple-chocolate cake, as does
Garden Grove, a Table Service restaurant inside Walt Disney World Swan Hotel. One of my new favorite restaurants,
The BOATHOUSE: Great Food, Waterfront Dining, Dream Boats, features a Double Chocolate Bundt Cake that is so darn good. Epcot's Sunshine Season's Chocolate Mousse Cake may become a favorite, too.
Other options include Mickey Mousse pastry at
Amorette's Patisserie,
Paradiso 37's Taste of the Americas' Paradiso Chocolate Stack &
T-REX's Chocolate Extinction (my favorite), all of which are available at Disney Springs.
May your search yield many new favorites, Susan! Send more questions as you plan; we love to help!
