Most of our cake recipes (like Mom's Chocolate Cake or Homemade White Cake for instance) call for butter and a bit of vegetable oil. However, this is the first chocolate cake recipe in our Cake Recipes section that calls for only vegetable oil. I thought that I might miss the butter but in this case, the chocolate flavor is just as delicious without it. This cake has a wonderful melt-in-your-mouth quality to it. The crumb is soft, tender, and fine. An advantage to using vegetable oil instead of butter in this fudge recipe cake is that the cake remains softer even at cold temperatures. This is because vegetable oil doesn't firm up when chilled like butter does. We have a few other favorite recipes that contain only vegetable oil, including our popular Carrot Cake, Classic Hummingbird Cake, and our new Apple Pecan Bundt Cake! If you haven't tried these delicious recipes, please put them on your list! They are fabulous.
