<p><strong>The Macamochip Cookie Ice Cream Sandwich at City Cakes ($6.75)</strong></p><p>Down in the basement of a nondescript residential building in Chelsea lurks some of NYC's most outrageous cookies, the insanely sweet (and delicious!) half-pounders at City Cakes. They also do elaborate custom cakes and such, but whatever: if you're looking for a meteoric sugar rush, wolf down just any of these big-as-your-head beasts, but especially the brand-new Macamochip, which is crammed full with milk chocolate chips, macadamias (our most caloric and fattiest of nuts), a thick layer of gooey Nutella, crispy rice cereal, and, if you want (and, yes, you do want) a double scoop of Fior di Latte gelato. Guaranteed to triple your heart rate in ten minutes flat! </p><p>City Cakes is at 251 West 18th Street (<a href="http://citycakes.com/">citycakes.com</a>)</p>
