Once upon a cupcake

​Andrea (Buswell) Hahn always had a creative passion for baking. Growing up she loved to make her "famous" chocolate chip cookies, and served them to her family. Over the years she learned more about the craft from the women in her family, especially from watching her mom decorate her and her sister's birthday cakes, as well as learning from her aunt, a professional baker and pastry chef instructor. After fifteen years in the corporate world, she was unexpectedly laid off and realized this was her chance to do what she loved. She made cupcakes for a few friends as baby shower gifts which led to a surge of requests and never ending orders. Andrea then spent time perfecting her original recipes and flavors, and one year and several pounds of sugar later, Frost Cupcake Factory was born! A local girl, Andrea grew up in Los Gatos, graduated from San Jose State University with a degree in Business/Marketing and continues to live in the South Bay.



It's what's on the inside that counts

We are a made from scratch, baked fresh daily, local bakery.  We take extra care in making our cupcakes perfect, beautiful and delicious! Frost opened it's doors in Downtown Campbell in July 2011 and two years later, we appeared on the Food Network's Cupcake Wars and won! Located in the heart of the Silicon Valley, Frost became the "go-to" cupcake caterer for so many of the corporate giants in the Bay Area. When we had the opportunity to increase our kitchen space by moving to a new location, we jumped at the chance. In 2019, Frost moved to the San Jose/Santa Clara border and had the ability to more effectively and creatively bake in volume. During the pandemic, we were lucky to be able to keep our doors open and provide a level of joy to our new and previous customers. We are so appreciative of every single customer, whether you are in it for a single cupcake to satisfy a craving, you are showing off your favorite dessert on your wedding day, or you want to reward your team at work with a delicious event. We are so proud to have made it over 13 years in business and hope that you will continue to support us as long as we continue to bake our little hearts out!



We're so proud we have to share!
