What could be more satisfying at the end of a meal than a slice of rich, fudgy chocolate cake? We’re big fans of this easy mix that delivers all the intensity of deep, dark chocolate without being too sweet. Simply add melted butter, water and an egg, and bake until your kitchen fills with the intoxicating scent of chocolate. Once cool, ice with the included chocolate frosting to double down on the chocolate decadence. For a fun variation, sprinkle with red hot candies for a spicy kick, perfect for July 4th or any holiday.
