Chocolate Marble Squares
I've never had a chance to sample this cake—I'm allergic to chocolate!—but everyone, especially my teenage son, tells me it's the best they've eaten. They must be right, because every time I've taken it to a church event or family gathering, someone asks me for the recipe. —Cheryl Scarf, Atlantic, Iowa
