Bon Appetit's Senior Food Editor and pastry chef Claire Saffitz attempts to make a gourmet Twinkie without the hard-to-pronounce chemical ingredients. The first test is Genoise cake, an Italian sponge cake. For the creamy filling, Claire uses 7 minute frosting. The second test is yellow cake and buttercream filling. Next comes chiffon cake, a light cake that uses vegetable oil. Finally, with some help from Test Kitchen Manager Brad Leone, Claire decides to "Frankenstein" the recipe.
