One way to do it is to use a cake decorating bag. Use a regular tip that would be used for large writing. On the top of the cupcake, poke the tip about three fourths of the way into the center of the cupcake. Squeeze the tube of filling and pull away from the cupcake. Don't let the filling ooze out of the cupcake. Gently scrape off any filling that is on the outside of the cupcake before frosting it.

Another way to fill a cupcake is to cut out a small section of your cupcake. This works especially well if your filling is thick or lumpy. At about a 45 degree angle, cut a small circular section out of the top of your cupcake - about 1 - 1 1/2 inches deep. Carefully remove that section. Fill your cupcake with the desired filling (frosting, cream, jam, etc.) and then replace the cut out section (trimming if necessary) then frost to cover up the patch.

Your friends and family will be amazed at how professional these cupcakes look and taste!
