Georgetown Cupcake Sisters Share Their Baking Secrets

YH heads to the L.A. bakery of Georgetown Cupcake, where sisters Katherine Kallinis and Sophie LaMontagne of TLC's "DC Cupcakes" have their blinged-out mixer at the ready! The ladies tell us the unique advantages of having a shop in Los Angeles, and then they show us how to make our own YH-inspired cupcakes out of their signature blue velvet batter!
