It's Mommy and Daddy's 40th wedding anniversary, and Sophie and Katherine are throwing them a surprise party, complete with a portrait of the happy couple in cupcakes. Meanwhile, Andres has ideas of creating his own cupcake.

Sophie and Katherine push themselves to the limit creating a cupcake wedding dress for DC Fashion Week. But after learning their dress has to not only look chic but walk down the runway on a model, have the girls bitten off more than they can chew?

Sophie and Katherine agree to make a giant pink bra out of cupcakes for Breast Cancer Awareness Month, and with their head baker Andres, the sisters compete in a three-way bake-off to create the pink cupcakes that will go with it.
