The Fourth Annual Havemeyer Sugar Sweets Festival

This humongous bake sale has lured sweet-tooth favorites from Momofuko Milk Bar, Salties and Peter Pan Donuts for a day of sucrose worship. Tots can get their faces painted, decorate aprons and join in a sugary singalong with Deedle Deedle Dees frontman Lloyd Miller—all for free! Amateur pastry chefs (that includes kids!) can test their confectionery skills in baking contests in the following categories: Best Vegan/Gluten-free, Best Fall-flavored treat, Most Creative Cupcake, Chocolatastic and Best In Brooklyn; sales will raise money for the City Reliquary, admission to which is free as well. All ages.
