Monday at 6 PM at the Veranda Inn restaurant (5700 W. Irving Park), Beautiful Cakes hosts Iron Cupcake Chicago, the first in what it expects to be a monthly series of cupcake bake-offs. The inaugural edition, to be judged by Chicago Bites team Bridget Houlihan and Tammy Green, challenges bakers to create cupcakes using citrus. To enter, register in advance (beautifulcakes@sbcglobal.net or 773-777-7535) and bring two dozen cupcakes for judging and sharing. If eating is more your style than cooking, just show up to taste the cupcakes; there’ll also be food and drink specials at the restaurant.
