It’s Boston against New York in the premiere of DC Cupcakes, the hit TV reality show on TLC Tuesday, October 9 featuring the sisters and co-founders of Georgetown Cupcake as they compete to see which location - Boston or New York - can sell the most cupcakes.

The hilarious showdown episode started as a contest between the sisters but quickly became a  Red Sox verses Yankees baseball themed cupcake showdown with help from Jason Varitek and Bernie Williams from the New York Yankees.

The show follows sisters and Georgetown Cupcake co-founders Katherine Kallinis Berman and Sophie Kallinis LaMontagne as they run and grow the wildly successful Georgetown Cupcake.

There are lots of surprises in the episode including one of the sisters driving a Duck Tour bus into the Charles River.  Fans of the show won't want to miss a big announcement at the end of the premiere episode Tuesday night.

Georgetown Cupcake opened its location at 83 Newbury Street back in June.  Katherine and Sophie co-founded the original Georgetown Cupcake in 2008 in Washington D.C. 

Growing up the two were inspired by their grandmother and gave up careers in fashion and finance to follow their dream and open Georgetown Cupcake.

Sophie says they got the shock of their lives the minute the doors opened.

“People could smell the cupcakes baking. There were lines around the block from the first day. The lines never went away." 

Katherine says the TV show came about by accident.

“A TV producer from New York was in line on day watching the chaos complete with mommy yelling.  He asked if he could film what was going on."

The producer took the footage to TLC and the DC Cupcakes was born.  And it’s been sweet success for the pair ever since. 

With locations in Washington, D.C., Boston, New York and Bethesda, Maryland, Georgetown Cupcake is set to open in Los Angeles later this fall.

The sisters and best-selling authors have been featured in the Boston Globe, New York Times and have appeared on the Today Show, Martha Stewart and the Oprah Winfrey Shows.  Their latest book Sweet Celebrations, a collection of recipes, decorating tips and memories, goes on sale October 9.

Even though the company continues to grow at a rapid pace, the sisters still come up with all of the cupcake recipes and marketing ideas complete with social media to promote the brand. 

Every day the secret flavor of the day is posted on their Facebook page and the first 100 people who mention it get a free cupcake.

With dozens of flavors, there’s a cupcake for everyone from vegan to low-calorie cupcakes for dieters.  

What’s the best-selling cupcake in Boston?  Newbury Street Manager Brian Jones says Bostonians can’t get enough of the red velvet cupcakes.

The Wicked Good Showdown episode premiers Tuesday, October 9 at 8 p.m on TLC.
