This 5-ingredient rocky road loaf cake could not be any easier—using melted ice cream as the base sounds crazy but when you think about it, ice cream has all the ingredients you’d need for a cake: eggs, sugar, and milk or cream. A little extra cocoa mixed into the batter ensures a deeply rich chocolate flavor and color, while marshmallows and chocolate chips, both folded into the batter and sprinkled over top, really drive home the ‘rocky road’ flavor.
