I learned to use an ice cream scoop to "scoop" cupcakes into cupcake liners after watching it done on Cupcake Wars. Life got so much easier!
Cupcake Project investigates this technique even further and teaches us which size scoop is best for mini, standard, and jumbo cupcakes. She uses three different "dishers" for the various sizes. For mini cupcakes use size 50 which holds 0.65 ounces. For standard, use size 24 which holds 1.33 ounces. For jumbo cupcakes use size 8 which holds 4 ounces. You can read the full post here.
