Ample Hills now has two brick-and-mortar locations plus an outpost in Gotham West Market and seasonal kiosks in Brooklyn Bridge Park and Rockaway Beach. The two-story Gowanus, Brooklyn, follow-up to husband-and-wife team Brian Smith and Jackie Cuscuna’s Prospect Heights scoop shop churns out ever-changing, off-the-wall flavors that will please inner and actual kids alike. Snap Mallow Pop, an überrich, jet-puffed marshmallow number studded with crunchy, toasted rice-cereal nibs, is as comforting as bake sale Rice Krispies Treats.
