We popped into this new place yesterday, located in the new Plainsboro Village Center.
They have several varieties of cupcakes and cookies, and serve coffee as well. We sampled a chocolate cupcake with chocolate frosting, and a coconut cupcake, which the owner mentioned was made with coconut milk in both the cake and frosting. Both were wonderful. Other cupcake varieties I noticed were Carrot Cake, Red Velvet, and Lemon. There were several others as well. The place itself is very pretty and nicely decorated. They have tables for eating in. A great addition to the area - we'll be back.
