Sibby's Cupcakery

Sibby’s Cupcakery is a boutique bake-to-order bakery in downtown San Mateo. We specialize in custom-designed cupcakes baked from scratch each morning.

Sibby’s Cupcakery was founded in 2004 with the mission of providing joy and happiness to its customers and community. Since then, Sibby’s Cupcakery — called “the cupcake center of the universe” by the San Francisco Bay Guardian — has been featured in numerous local and national publications, including San Francisco Modern Bride, Daily Candy and Lucky Magazine, which named it one of the best places for baked goods in Northern California.
