"DC CUPCAKES: MOMMY'S BIRTHDAY BASH" PREMIERES MAY 11 at 10 PM (ET/PT) on TLC

It's Mommy's 60th birthday and Sophie and Katherine want to honor her in the best possible way -- with a surprise birthday party, complete with a life-sized Greek statue of Mommy made out of cupcakes. But before they can prepare for the party, the sisters must handle one of the busiest weekends in Georgetown Cupcake history, filling orders for eight weddings! Stress and tension mounts as Sophie and Katherine must find time to run their business and make the elaborate preparations for Mommy's surprise party.

DC CUPCAKES shares the recipe to Sophie and Katherine's sweet success, following their journey as they navigate the challenges and rewards of building a booming cupcake business. Each half-hour episode goes beyond the frosting to capture the behind-the-scenes drama in their fast paced, family-owned bakery. From baking and decorating thousands of gourmet cupcakes a day, to meeting tight deadlines for discerning clientele, to securing large projects such as fundraisers, festivals and weddings, there is never a dull moment with this sister duo. Mixing in their Mother ("Mommy") -- who plays a big part in running the family business -- adds to the chaos and family drama. The other staff members are as colorful as their cupcake creations--their small workspace, sprinkled with the high volume of business, leads to family bickering and staff tension that has more icing flying through the air than on the cupcakes.
