I've ordered custom cupcakes from Sibby's in the past. They always do a beautiful job with making something super unique! And usually you need to order them in advanced for pick up. Today I just wanted to stop by to see if I could get lucky with any daily cupcakes they have in-house. Little did I know that now they have a full display of many flavors in mini, regular, and jumbo sizes that I could takeaway in a nice box day-of! I don't know if that's always available, but it was fortuitous that I needed some birthday cupcakes for a couple friends today. I usually get cupcakes as gifts for others so I can't speak on the taste. But the women in there were friendly and helpful and patient while I combed over all the options. Guess I'll have to come by and get a sweet treat next time! read more

I heard about this bakery on TikTok--and happened to be in the area a few weeks ago! I snagged 2 GF cupcakes for myself, and they absolutely lived up to the hype! So delicious!! Consistency was like a regular cupcake, which is hard to find. My family enjoyed the regular treats. Parking can be a little tricky, but I found a spot around the corner. It's one guest at a time, so there was a short wait--but that just meant I had their full attention when ordering for myself. Will always stop in and grab treats when I'm in the area! read more

Here are the cupcakes I tried: Salted caramel - delicious middle, slightly smoky flavor to me (no one else agreed with me though so maybe I have weird taste buds), would try again! Seasonal lemon meringue - nice but not as good as the salted caramel :) read more

Such a wonderful place with absolutely delicious cupcakes!

I'll definitely be back many more times, both for a sweet treat for myself and for future celebrations! read more

Ordered minis for an event and they were beautiful and perfect! The dense chewiness of the frosting and cake are unique and addictive. We just did the funfetti ones and they were great! Everyone loved them. read more

I stumbled upon this place while looking for mini cupcakes for my daughter's birthday. I ended up with half a dozen of cupcakes for us to try, and I was amazed by the flavors. Not to mention, they're beautifully decorated and the cupcake was moist also. The lady who helped me was also friendly and helpful. I probably will visit this place whenever I'm in the area! I ate 2 out of the 6 she was supposed to try. Oops read more

Just gave this place a try. It's a bit out of the way, but the trip was WELL worth it! Tried out both the Salted Caramel and the Red Velvet. Both were absolutely DELICIOUS, especially the former! And the people working there were kind as well, which is always a plus. Only knock against them is that the Salted Caramel is ONLY in the Mini form. Would KILL to have a full size Cupcake of that flavor. But I'll definitely come back in the future! read more

The cupcakes here are BOMB. Not only are they delectable but they're also so cute and aesthetically pleasing. The last time I was here I had the "butter cup," a classic vanilla cupcake with buttercream frosting--but it was THE BEST vanilla cupcake I've ever had. "Grandma's chocolate tea cake" was decadently rich and chocolaty, and the Hostess chocolate cupcake look was wonderfully nostalgic for this 90s kid. I've also had lemon drop which was light and refreshingly citrus. My volunteer organization provided Sibby's cupcakes for a private event and every single cupcake I had was so good, I don't care to say how many I ate . The neat thing about Sibby's is they also have gluten-free options and are completely peanut-free and tree nut-free. The location is in an odd place adjacent to downtown San Mateo with plenty of paid parking nearby along the train tracks, and a few limited parking spots right by the bakery. It's a takeaway only place with only a counter right by the door. The prices of the cupcakes are reasonable for the quality you're getting. This is worlds beyond the junk full of vegetable shortening "icing" that you would pick up at a local grocery store. read more

Found this cupcake shop randomly on a drive and loved the cupcakes. It's hidden in an industrial area but don't let that fool you. They have great cupcakes. I recommend giving it a try. I bought a box of three cupcakes to share with family and everyone loved them. It seems like most people order the cupcakes ahead of time and simply pick up their orders. But you can walk in and pick one up. read more

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. read more

Great selection of flavors and quality cupcakes. Ordered for parties and work events and always a hit! Favorite flavors include: Carrot, Chocolate, Salted Caramel read more

Favorite cupcake shop in the peninsula that's hidden a few blocks away from the heart of downtown San Mateo. You really can't go wrong with any of their cupcake flavors (seasonal flavors rotate monthly) and they have a big variety so everyone's happy! Cupcakes are all moist and just the right amount of sweetness so you don't feel guilty indulging. Also love that they have mini size cupcakes in most of the flavors so you can try multiple. For those that have dietary restrictions they do offer gluten free and even have a vegan option (you have to order ahead and it's a chocolate cupcake with powdered sugar). read more

It's not a usual place for a bakery, but their cupcakes are amazing. I needed to pick up a small dessert for my daughter's birthday and I saw this was in the area after our afternoon at Gama Ride. I'm so glad we decided to try this place out. They didn't have many flavors left since it was near closing time, but I managed to pick up the carrot, a couple of holiday confetti and regular confetti, and a couple of the dulce de leche ones too. I tried the carrot one first and it was amazing. The best carrot cake/cupcake I've ever had. My daughter and son enjoyed the confetti ones and dulce de leche were good too. We had gotten the mini cupcakes, but they have regular and XL cupcakes too. The XL cupcakes were huge. I would love to come back and get another carrot cupcake and try the other flavors that sold out before we got there read more

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!! read more

Finally found a fantastic place for all my custom cupcake needs! I was in a pickle because I hadn't been able to find a reliable custom cupcaker in the RWC area. I was referred to Sibby's by a coworker and was immediately impressed with their website. I found exactly what I was looking for under their custom design page (train themed cupcakes), and was thrilled to see they offered 3 different sizes and customization of flavors by the half dozen. I called my order in because I had some questions about delivery versus pickup given my event was on a day they were closed. The staff was friendly and accommodating, helping me get my order in and recommending flavors based on popularity. I ended up doing 2 dozen regular, 2 dozen mini, and a jumbo for the bday boy. About a week before, I called to confirm my pickup time and day of, I went to collect the cupcakes. Pickup was fast and easy - pull up, call them, they bring the order to your car. Ample parking near the storefront as well. The cupcakes turned out better than I even imagined! The designs were flawless and they tasted even better. I ordered way more thinking we'd have leftovers but they flew off the plates! Our guests were all asking where we had gotten them! Will definitely be using Sibby's for all my future events - and ordering extra for myself ;) Thanks, Sibby's, for making my son's birthday desserts a hit! read more

I have been coming here for 15 years. I can't believe I haven't reviewed. These are the most amazing cupcakes in the world. They are incomparably delicious. They are beautiful pieces of art. They make any celebration an experience. But an experience experience. Making the event worthy of core memory building. I love these cupcakes so much, but I also love how popular I am whenever I bring them to an event."Who brought the Sibby's??" Honestly don't worry about the price. These are not in the same leagues of other cupcakes. They are a bargain for the joy they bring everyone. read more

Sibby's Cupcakery - A very happy birthday girl. - Cupcakes Near Me - San Mateo, California

Having a super crappy week and decided my 8 Ozempic bites were going towards something satisfying and carb loaded lol - drove to Sibbys and there were already people in line right at opening. Ordered a single regular sized Choco Choco cupcake for myself . Took the long way home to drive on a very fast road, also to make myself feel better, then arrived home with my precious. It seemed a little small for over $4, but then if I think of getting a dozen for under $50, it seems appropriate, if delicious. Well I ate my precious forbidden cupcake and enjoyed each bit. I savored it. I loved it. I made it to 5 bites but it was so good I couldn't take smaller bites lol just delicious. I wasn't in the area, I have no excuse. I drove from home to Sibbys just for a cupcake and it was worth every bite and drop of gas lol read more

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. read more

Love stopping by this nondescript storefront on an industrial street and picking up some delicious cupcakes! The seasonal monthly assortment boxes are perfect for sampling with a friend, and they have three cupcake sizes that meet whatever your needs are. Mini cupcakes are just enough for a couple sweet bites or sampling multiple flavors, regular cupcakes are a great amount for a satisfying dessert, and the large cupcakes are fun to share with 2-4 people or makes a fun birthday treat to put a candle on! The cakes are moist, the frostings not too sweet, and the decorations are very pretty. The staff are kind and wrap the cupcakes well, and even include a happy birthday sign to stick in your cupcakes for special occasions! read more

Best cupcakes I had ever have I ordered two dozen mini cupcakes for my birthday and family reunion, so we can taste the different flavors. They are all good!

I couldn't ask more for the service! Thank you so much, Sibby!! read more

Sibby's Cupcakery - Month of March '25 - Cupcakes Near Me - San Mateo, California

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! read more

Still the best and most moist cupcake in the Bay Area. Their flavors are delicious. Sweetness is on point. Decor is outstanding. I was a tad disappointed because I did not realize until pickup that I ordered minis. Minus are not worth it. Get at least the regular. Giant is too expensive for what you get. We will be back! I need to celebrate everyone's birthday. read more

I planned my sisters bridal shower and I am so glad I picked sibbys cupcakery for the mini cupcakes! They came out to be so cute/classy and exactly what I hoped it to be. When I was placing the order online I was a little worried because I didn't know what design they were going to use. I just wrote in the comments to do all white bridal theme and I am pleased with the way it turned out! I got the vanilla, confetti, and snickerdoodle flavors. My favorite was the snickerdoodle so I highly recommend getting that. I also loved how easy it was to pick it up - you just call and they bring it out. It's been 3 days since I picked it up and they still taste great! Will be ordering from them for my next event. read more
