This tiny little bakery is our go to anytime we are in town for nut free treats. The flavor options are wonderful and there are always seasonal options. Come early for or order online for pick up for the best chance to get all flavors. They tend to sell out of some flavors in the afternoon.

They had multiple gf flavors,including carrot cake and red velvet. The staff was kind and knowledgeable regarding gf.
I got the mini vanilla and mini red velvet-they were delicious. They
stored the cupcakes in a different area- did not ask about dedicated baking space. I did not get sick and im very sensitive with cross contamination, so my guess is they are very careful. If I lived closer, id go often!!

Best cupcakes.

We were going to host a birthday party at my 2yo’s preschool, school requires pastries that contains absolutely no nuts or any cross contamination. Luckily we were able to find Sibby’s!

A good story always has a twist, bb gal got sick right before the party day. So some of the cupcakes went into my tummy muhahahahaha~ (that wasn’t the original plan but hey ;))

I love that the icings are not super sweet (but still sweet enough). Inside of the muffins there are these dots of colorful creams, that makes every bite delicious and fun.

The cupcakes here are heavenly! I learned about them too late.
I had the mango coconut mini and it's the best cupcake I've had in a long time.

Time and time again, I am met with rude customer service. Just short and snappy when talking to me. Cupcakes are good.

I haven't got a chance to visit the shop by myself but my friends bought a bunch and I got to try the chocolate and the carrot ones. I love the variety of the cupcakes. Their cupcakes are moist with not overwhelming amount of frosting. I wish they could be bigger, but bigger doesn't always mean better anyway. I would love to try more flavors next time!

Love their cupcakes. They are exquisite and very delicious. The customer service is A Plus. Even though it’s next to the railroad, they do a great job decorating and making it a cute little store.

Your containers should be better fitted to keep the cupcake from sliding around in the box which ruins the icing of the cupcake. I went to your shop for a pretty cupcake to be displayed at a party but it moved around unsecured in the box and was worthless when i got home as it was unsightly along the edges. You should use containers that secure the cupcake from moving around in the box to prevent it from getting ruined in transit.

Cute little bakery in downtown San Mateo that specializes in custom-made cupcakes. Decadent toppings, inventive coloring and designs, along with a well-trained friendly staff all contribute to a phenomenal experience. Definitely call them if you ever need to buy large amounts of cupcakes to impress your neighbors or colleagues!!
