Cupcakes on Kavanaugh has opened at 5625 Kavanaugh Blvd. across from Mary Healey’s in the Heights. Every day the store offers four “classics,” all of which involve some combination of vanilla and/or Ghirardelli chocolate, and three to five specialty varieties. Because of a high demand and start-up kinks, the cupcakery has been open only from noon to 5 p.m. Tuesday through Saturday, though in the two weeks the store has been open, the cupcakes have frequently sold out before five. Look for an 11 a.m. opening time in the coming weeks. The phone number, appropriately enough, is 664-CAKE (2253).
