Sisters Sophie and Katherine own and operate one of the most successful cupcake bakeries in Washington, DC, "Georgetown Cupcake." In this episode, the sisters agree to donate a huge Mardi Gras mask made out of a thousand cupcakes for a local fundraiser.

Sophie and Katherine offer to support a DC Animal Rescue fundraiser by creating a life size dog out of cupcakes as a centerpiece for the event. In the process, they also develop their first ever "pupcakes" for the gala as well.

The sisters offer to come up with a Greek inspired cupcake and a giant work of Greek art made out of cupcakes when "Mommy" invites her Greek Orthodox priest to the bakery to participate in an upcoming Greek festival.
