Fillings shouldn't be reserved only for doughnuts. In fact, jams, icings, custards and creams of any variety add extra panache to most cupcake recipes. When your cupcakes have cooled, use a decorating bag and tip to inject the filling of your choice into the top of the cupcake. To cram in even more of the good stuff, you can hollow out a small portion of the cupcake, fill it and plug the hole with a piece of cake or with a generous dose of frosting. Boston Crème Cupcakes from HowStuffWorks are only one example of scrumptious filled cupcakes.
Stirring mix-ins into the batter is another easy way to lend more flavor to the most basic cupcake recipe. Even small children can help with this step by adding sprinkles, fruit, candy or finely chopped nuts to the mixing bowl. This cupcake batter will yield an extra-special finished product.
