Williamsburg, Brooklyn-based Kumquat Cupcakery has been doing brisk business since being featured in Time Out New York. But you can still catch owner Keavy selling her cupcakes every weekend at Artists and Fleas, the very cool flea market on North 6th Street. Here's some pics from this past weekend - I can attest that the banana creme cupcakes were yummy and unusual. My friend tried the lavendar one and, well, she did not enjoy it too much. The others were chocolate hazelnut and chocolate cherry! What I love about Kumquat, aside from the size and adorableness, is the constant rotation of flavors.
