Bake your cupcakes and allow to cool.

Spoon out a small section in the top of the cupcake. This is the filling area. Be sure not to go all the way to the bottom of the cupcake.

Add filling. This is the sprinkles or candy you have for the surprise inside. We used these red candy heart sprinkles.

NOTE: When I made these surprise cupcakes for the pictures, I really should have used more filling. While it was plenty of filling when we ate them, to make it look pretty and let you see the effect, I should have used more.

Put the top back on the cupcakes and it is ready to frost.

You can frost the cupcakes any way you like. If you want the "professional" looking icing, use a piping bag and tips.

You can add sprinkles or candies to the top of the cupcake as well.

Enjoy.
