The best cake I've ever had in my life is the Creme de Casis cake at Bonte Patisserie on 75th and 3rd Ave. Unfortunately, they couldn't renew their lease and closed its doors almost 10 years ago.
Here are a couple of cakes from Financier Patisserie. I don't remember what the one in the back was called, but it is very very good. The one in front is mango coconut.
These are not cakes, obviously, but they are macarons from my favorite patisserie ever, Bay Bread / La Boulange in San Francisco.
Dessert sampler from Finale in Boston.
Strawberry pistachio stuff from Le Norte in Bangkok. Wasn't the best, but I had a picture of it so I thought I'd share.
Cupcakes from Sugar Sweet Sunshine.
