Preheat your oven to 350°F.
Measure all the dry ingredients into an 8 or 9-inch round or square cake pan. Blend these together thoroughly with a fork and scoop out two holes, or indentations.
Pour the vanilla into the hole, the vegetable oil into the second.
Take the cup of cold liquid (buttermilk or tomato juice) and pour it directly over everything in the pan. Stir all the ingredients together with your fork until they are well blended.
Bake for 30 to 40 minutes. Serve right from the pan; warm from the oven, this Cake-Pan Cake is wonderful with a big glass of milk (skim, of course!)
