Sibby's Cupcakery

At first I didn't realize it was a storefront because I think they do the bulk of their business as pre-orders for events. But alas they do have a storefront that you can walk in. It's not a typical cupcakery storefront like Kara's or Sprinkles which is bright and cutesy located in a shopping area but more like a display case in front of their kitchen and office across the railroad tracks in an industrial area. Kind of looks like a hidden place you need a password for.They have 3 sizes of cupcakes which is nice to choose from: Large which I believe is the equivalent of 3 cupcakes, regular, and mini. A list sits outside where it shows the cupcakes offered for the day. You don't get as many options if you walk in, especially at the end of the day. I like the Jimmie cake which has sprinkles and the confetti cupcake the best.

Ordered some cupcakes for my boyfriend's birthday and they were a big hit. I did a split dozen of Carrot Cinnamon and Grandma's Chocolate Tea Cake. The packaging was a simple pink pastry box but I love the added bow and the option to add a note card. They have a decent selection of decorations for birthdays and other occasions.My only issue was that you can't order an assortment of cupcakes with the decorations. You can order up to 2 flavors for a dozen, and I do appreciate you can order at different sizes of the cupcakes themselves, but would have been nice to have a little bit more of a flavor option because a lot of their options sound really delicious. There is a predetermined assortment, but I tend to be overly picky , so that could just be a personal issue and should not be a hindranxe in ordering from here!

Sibby's is now my favorite place for cupcakes. I have a life-threatening peanut and tree nut allergy and I was very excited to read that Sibby's is nut-free. My boyfriend and I visited on a Sunday to try out a few flavors and they were all delicious. We ordered the carrot cake (nut-free!), funfetti, and pumpkin cheesecake. *chef's kiss*The bakery is small and they have a displace case at the front with the available flavors. It's pretty cute inside with all the pink. The workers are all really friendly and nice, which is always a plus.

The Valentine's cupcakes were beautiful and very well made, rich in flavor plus the soft sponge! Will definitely be a regular treat for my family, friends and I!

Ordered gluten free cupcakes from Sibby's, they were so knowledgeable about avoiding cross contamination and I am so grateful! Their cupcakes are delicious & the gf ones / can't even tell the difference. They have such a wide variety of flavors. Yes the cupcakes are a tad pricey, but worth it. Ordering, pickup, and consumption wereAll EASY and enjoyable experiences! Be sure to stop by and indulge!!!!

Ok, so if you're in the SF Peninsula and are looking for some amazing cupcakes.. LOOK NO FURTHER! I have lived in SF and used to amazing spots for food and desserts! This is my fave in the peninsula!! I always order a dozen cupcakes and love getting random flavours. Sibby's has great flavours and always tastes freshly baked and with simple, real ingredients. You can taste the sweetness without the artificial sweetness taste (if that makes sense)!?!I have tried many flavours and always satisfied with every bite! They are dangerously good! Be forwarded, you won't just want to eat one! This place is nestled near downtown San Mateo with street parking that is metered. The place is small in size but create many delicious desserts! The price point is on par with many high end bakeries that have amazing quality and taste.The staff is super friendly and helpful every time I had gone. If you're in the area, I highly recommend this place!! You won't be disappointed!!

If you are gluten free or know someone who is, you have found your nirvana. Glorious flavors, beautiful creations and pure joy in a pink box. I've had these gf cupcakes many times, and they never disappoint. Friendly and prompt delivery available. Superb in every way.

My husband and I walked in to Sibby's and got 4 different cupcakes. It's mostly a place where you order in advance but they have some cupcakes for walk ins. I'm not too fond of eating big quantities of desserts so I really liked their mini size. We got the strawberry and cream (current special), red velvet, chocolate and cream and coconut snowball cupcakes. They were all delicious especially the strawberry and chocolate ones. The frosting is on the sweeter side but I guess most people like that in cupcakes. My husband is definitely looking forward to going back and trying their other flavors!

I was looking on Yelp for a custom cupcake shop and came across Sibbys. It was a very simple online process of placing my custom order for an engagement party. We got red velvet, vanilla, and lemon with cream cheese frosting. They were delicious as well as with a cute variety of designs. I would definitely recommend!

Great cupcakes! Great service. We ordered dozens for a work event. They were delivered on time and everyone loved them. Gluten free & vegan option too!
