Easy. Hands down (okay, okay, IMHO!) best birthday cake you can get is from Duane Street Patisserie on, yes, Duane Street in Tribeca. Moist cake layers, wonderful ganache or buttercream filliings...you can happily combine them to create your perfect cake. They can do beautiful floral designs, or whatever pleases you. A friend used them for her kids' birthdays (the kids didn't care...but the adults at the party were overjoyed to eat such good cake) recently and they made an adorable plaque of a monkey for one and a pirate flag for another...The monkey cake had a scrumptious banana mousse filling. All the ingredients are the best of the best...They cake is simplicity itself, and yet elegan. None of this hyper-sugar-overload that you get from places like Magnolia. And, speaking of cupcakes...their take on a Hostess cupcake is tops. It is my birthday cake place of choice. I hope you like it too. (At the very least, try the cupcake!)
