We have been ordering and eating Sibby's at events around the area for years. However we just found out that you can go into the small space and buy individual extras each day. I don't know how we missed this but its a wonderful way to try out favorite flavors as well as any flavor of the day the bakers... More

Always insist that we get Sibby's each trip we make to Hillsborough from the East Coast. Her cupcakes surpass any we have in DC including Georgetown Cupcakes. Yum!

This was slightly difficult to find for an out of towner and it’s on kind of a strange street. I walked past open garages and what looked like workshops to get to Sibby’s... But make sure you run here as fast as you can. If you’re a fan of cupcakes, this place has hands down nailed this business. I had... More

You won't find any better cupcakes anywhere than at Sibby's. And they will custom any logo, any college, any flavor, and ALL are fabulous. I've ordered baby shower & wedding shower cupcakes from here. Or get ONE LARGE cupcake for the Birthday Person. Delicious!

On our way to SFO airport from San Jose, we took a small diversion and visited Sibby's Cup Cakery. The shop is located in a quiet street. On query, they replied that they prepare Cup cakes in the old fashioned way - generally on order and supply. Few people directly visit the shop to eat. Any how, we bought few... More

What's there in a cupcake? But if you have a sibby cupcake it makes a difference. Two, three tastes in single cup cake , no other can give this. Whether it is a blend of lemon and vanilla or red velvet with something else.. Fine texture and so soft it melts in the mouth. Believe me once is never enough

I stumbled upon Sibby's 2 years ago when I brought some motorcycle parts to milled for DH. I drove down the street which is spitting distance from the CalTran RR tracks, all the businesses are light industrial, metal fabricating, small auto shops and the like. And then there is a bright pink beacon in the middle of the block. So... More

They take orders for cupcakes, but do have extras for purchase. Sometimes you have to go early to get a variety. Nevertheless, I have always enjoyed the consistency of the cake and their toppings. Most are not too sweet. The prices are similar to what you would find for other Bay Area cupcakes, but Sibby's is located in an unusual... More

The cupcakes were adorable and tasted great. I picked up at the San Mateo location and they were ready to go as promised. I had emailed over some sample colors and they were matched perfectly. They were for a bridal shower and were a big hit. Will definitely order again.

Definitely place order in advance. They make a good moist cupcake. Their choice of buttercream or cream cheese icing is just ok. The icing flavors don't necessarily change the cupcake experience or make you think you're eating a different flavor cupcake. Their large cupcake (not the cakesize) cupcakes are good but I don't think they're a whopping $8 good.
