Hiya Loriana,
Welcome to planDisney! In my house, there is never a wrong time for cake; being able to add it to a delicious meal at select Disneyland Resorts is icing on the cake (pun intended).
You can pre-order one of Mickey Mouse's delicious
Celebration Cakes for your dining experience at
Blue Bayou Restaurant,
Café Orleans,
Lamplight Lounge,
River Belle Terrace, or
Wine Country Trattoria online when you make your advanced dining reservation. Before you confirm your reservation, it presents an option to select a cake, choose the flavor, and a desired engraving if you are inclined. If you have already made your reservations, you can also order one in person at the restaurant's podium (if this is a same-day request, it must be done this way), or if you are staying at one of Disneyland's Resort hotels, you can do so at the Concierge desk in advance. Please note that if you order your cake at the host stand that same-day cakes are subject to availability.
I hope this was helpful, Loriana. Whether you are celebrating something special or just commemorating being at the Happiest Place on Earth, I hope your celebration is sweet! Please come back and see us if you need anything else.
Happy Planning,
Ashley F.
