The sisters of "Georgetown Cupcake" already believe they make the world's best cupcakes, but now they're out to break the world record for the largest one! With the help of their team, will they succeed in creating a one ton cupcake?

It's Mommy's 60th birthday and Sophie & Katherine want to honor her in the best way -- with a surprise party, complete with a Greek statue of Mommy made out of cupcakes. Meanwhile, it's a busy weekend at the shop as the Sisters must fill 8 wedding orders.

After opening two successful shops, Sophie is ready for expansion with her eyes set on New York City. But her sister Katherine has reservations about the idea, especially after seeing the only potential location they can afford.
