Pleasantville, NY, has a rich history--it was a Dutch trading post as early as 1695.
But even more interesting: its rich present, particularly the buttercream dream that is Flour & Sun Bakery, just off of the metro north train.
When I recently headed up to Pleasantville to meet with my awesome literary agent Gail Fortune, I had the exquisite pleasure of meeting one of the managers and bakers, and--most importantly--the chance to sample some of the goods.
Choosing was difficult--after all, they had a stunning array of delicious flavors. On any given day, the assortment could include such choices as chocolate cookie dough, fluffernutter, Cereal (vanilla or chocolate cupcakes topped with fluff or chocolate fluff rolled in cereals such as Trix, Cocoa Crispies, and others), Magic Bar, Orange Poppyseed, Watermelon, or Pumpkin Pie.
I went for a special that day--chocolate halva--as well as the Banana Peanut butter (decorated to look like a monkey! shown above), as well as a chocolate and a vanilla-strawberry specimen. I brought them back to the city with me, and this was such precious cargo. I think that everybody in Grand Central Terminal was looking at me with jealousy in their eyes.
As the friendly manager had informed me, they are famous for their chocolate cake, which is dense and fudgy--almost brownie-like. No dried-out chocolate cake here, thank you very much. The vanilla cake was similarly dense, but very buttery and flavorful. My favorite frosting was the intriguing halva, which was nutty and sweet, and really did taste like the love child of the classic middle eastern confection and american buttercream. In a very good way.
Worth a trip from NYC alone? Maybe not (unless, like me, you are willing to travel an hour just for a cupcake), but if you find yourself headed north of the city for whatever reason, definitely worth a detour. 
Also of note: Flour & Sun also makes decorated cookies, as well as Cupcake Truffles ("cupcakes and icing mixed to an ooey-gooey truffle-like consistency dipped in chocolate and decorated. Truffles are also available on a stick to ad a fun and celebratory element to any party.")
