Georgetown Cupcakes has 18 different varieties of cake, some seasonal. Their most popular flavors to date are lava fudge and springtime lavender.

Today, the sisters bake over 25,000 cupcakes per day across six locations. The confections are shipped all over the country, and the sisters have not only published two cookbooks, but scored a reality show on TLC.
