Spectacular-looking cakes occupy the cases of Cupcake Café: great cylindrical layer cakes enrobed in multi-colored frosting in the shape of sunflowers, peonies, and lilacs. Proprietor Ann Warren is known for her chocolate cake with mocha icing, decorated to fit whatever occasion you need to celebrate. Lovely as the big frosted beauties appear, they are not what draw us to this corner bake shop west of Times Square just down from the Port Authority terminal. We come to Cupcake Café for simple pleasures: donuts, muffins, whole apple pies (double crust or streusel-topped), and – need we say it? – cupcakes.
