There are various ways to make a cake. Some use a lot of fat, other don't use any; some separate the eggs and others beat them whole. What are the different methods, and why choose one other the other?
For a quick and easy cake, I'm a fan of the all-in-one method. Pretty much, those cakes that you can put all of the ingredients together into a mixing bowl and mix to create the cake batter in seconds! Soft margarine works best in these kinds of cakes.
For example, for a quick all-in-one chocolate cake, place 175g of margarine, 175g of brown sugar, 2 tablespoons of water, 3 tablespoons of cocoa, 175g of self raising flour, 50 g of ground almonds, and 3 large eggs into a mixing bowl and beat with an electric mixer or wooden spoon to combine, then bake!
I generally use the creaming method, but I think that the different methods have different applications, depending on your intended results. For general cakes and cupcakes though, I do tend to stick to creaming.
Of course then there are the times when I end up forgetting a step and just add everything in any which order.
