Check out this mind-bending trailer for the new BabyCakes app. It's got gluten-free space brownies, Brooks Headley, and Sally Draper. Erin McKenna, who owns the immensely popular bakery, wrangled recipes from the Del Posto pastry chef and Momofuku Milk Bar's Christina Tosi, and met up with food writer David Lebovitz and Mad Men's Kiernan Shipka. She even enlisted J Mascis of Dinosaur Jr. to write a theme song called "Alien Parfait" to accompany the wheat-, egg-, gluten-, dairy-, and processed-sugar-free bakery's very first app. The result, which McKenna calls a "televisual cheatsheet for vegan and gluten-free baking," even has some new recipes, and it's definitely the only one of its kind that boasts not only "three or four babies," but also Mark Bittman.
