sharing some information about cup cakes..

A cupcake or fairy cake is a small cake designed to serve one person, usually made in a small paper cup container. As with larger cakes, frosting and other cake decorations, such as sprinkles, are defining characteristics of modern cupcakes.
Cupcakes are often served during a celebration, such as children's classroom birthday parties. Additionally they can be served as an accompaniment to afternoon tea. They are a more convenient alternative to cake because they don't require utensils or dividing into pieces because they are smaller.
A simple cupcake uses the same ingredients as most other standard cakes - incorporating butter, sugar, eggs, and flour.
The name "cup" cakes or "measure" cakes is believed to have developed because of the use of the practice of measuring the ingredients using a standard-sized cup instead of the previous practice of weighing the ingredients.
It is also possible that cupcakes came into being simply as smaller versions of the Victoria sponge cake, as the mixture required is exactly the same. The mixture is also the same as the quarter cake recipe, so called because it is made up of four ingredients in equal ratios; butter, self-raising flour, eggs and Castor sugar
