    Mocha crunch cake
    Sho R.

    I ordered a mocha crunch cake for birthday. Price was reasonable. They were nice to give a happy birthday ornament and some extra crunch toppings. Overall the cake had a variety taste.

    I first tried Claire's Crunch Cake at a 2025 Friendsgiving and immediately knew it would be the perfect choice for Christmas dessert. Claire offers four different flavors: lemon, mocha, strawberry, and pineapple. Food 6" Lemon Crunch Cake - $40 A two-layer lemon cake with lemon filling, paired with a bag of lemon-flavored crushed honeycomb to sprinkle over the frosted cake. Light, citrus flavor profiles, and refreshing. 6" Mocha Crunch Cake - $35 A two-layer mocha cake with mocha filling, accompanied by a bag of original honeycomb crunch pieces for topping. A good balance of sweetness and subtle mocha flavor. Between the two, the lemon crunch cake stood out for its citrus-forward icing. Neither cake was overly sweet and packaged in a white cake box with clear windows to easily see the cakes. The recommended approach to sprinkle the crush honeycomb on the cake is the following: Place a sheet of foil or parchment paper underneath the cake, set the cake on top, then pour the crushed honeycomb onto the foil around the base. Gently press the honeycomb against the sides while rotating the cake in a circular motion until the exterior and top are fully coated. Customer Service Although Claire's Crunch Cake is active on Instagram (@clairescrunchcakes), she does not take orders via DM or text. All orders must be placed by calling (650) 344-8690. I called and placed my order which was arranged to be picked up the day before Christmas Eve. When I arrived, several customers were already lined up along the walkway in front of the home. Once I was at the front door, an employee asked what the order name was under and what was ordered. My order was retrieved and I provided the cash. The employee explained the differences between the two cakes. Only cash is accepted as the payment method. Note: During holidays, there may be specific pick-up windows. Ambiance The scheduled pick ups are at a single-family home in San Mateo. A flag banner on the front porch displays the menu with 6" and 8" sizes and cake options. Location / Parking The home is nestled on a narrow residential street with very limited parking. Luckily, I found a spot directly across the street before a wave of holiday customers arrived.

    I can be kidnapped with the promise of dessert. As we drove through the unfamiliar suburbs of San Mateo, my companion asked, "Where the hell are you taking us?" Duh. To get cake. I'll go anywhere for cake. My longtime Yelp bookmark Claire's Crunch Cake bakes & sells out of a house. I called before stopping by & was soon engaged in the deal of the century: $35 cash in exchange for a 6" mocha crunch cake. The yellow cake is a bit dense & not as moist as other crunch cakes I've had, but the mocha flavor is pronounced & the honeycomb bits & pieces really make the cake unique. It's not as good the next day, as the honeycomb flattens out. Just another reason to give into my addiction & finish off the cake the same day I buy it.

    My friend posted a Strawberry Crunch Cake from Claire and I just had to try it. It was a little difficult to get my order in. She only takes orders on a landline and her voicemail is always full. I called every day for a week before I was able to get a hold of Claire. It was worth the effort. Everyone loved the cake, even my mom who is tough to please. She had 3 slices so that tells you how good Claire's cakes are. Be aware that you need to eat it within the same day because the honeycomb gets mushy the next day. Can't wait to order again!

    Claire makes a fantastic crunch cake that is moist, tasty, full of flavor, and given that extra crunch we love. Her cakes rank 5 stars. We are particular about our cakes. I'm a fair baker and love to eat. Try her cakes. Great service. Cakes were available on time and the presentation was excellent. The Professor

    Hell yeah I recommend this business. The cakes are fantastic Of course you know to try their phone line in the morning and keep trying so you can get a cake reserved. I love the lemon crunch cake. I follow Grub with Mike and instantly knew I had to try this. The cake is moist and the lemon isn't too overpowering. My family loved this cake so much that it has to be a special occasion order next time!

    So delicious and so friendly! That pretty much sums up Claire's Crunch Cake. Picked up a cake for my father's birthday and he absolutely loved it, because it brought back memories of cakes he had growing up in SF. The cake is moist inside and the crunchy bits on the outside are so tasty. As far as cakes go, this one is in a class of it's own.

    Tried Claire's Crunch Cake and it absolutely lived up to the hype. I ordered the 6-inch strawberry crunch cake, and it was perfect from start to finish. The cake itself was moist and fluffy, layered with just the right amount of cream, and the strawberry flavor tasted fresh. Not overly sweet or artificial. The crunch topping is what really makes it stand out, adding great texture and a nostalgic strawberry shortcake vibe in every bite. Portion size was ideal for a small celebration, presentation was clean and beautiful, and it tasted just as good as it looked. You can tell a lot of care and quality goes into their cakes. If you're a strawberry lover or just want a solid, crowd-pleasing cake, this is a great choice. Will definitely be back to try more flavors.

    The long drive is worth it. You can request to separate the crunch when you're having a long drive! The best cake and they are really nice.

    Mocha crunch cake is the best. Service is really good and very accommodating on our additional order.

    Yum - what a delicious cake! I won't lie, it's pretty darn hard to order since she doesn't always pick up and there's no store front. But it's SO WORTH IT. The crunch is almost like a softer, spongier toffee brittle. The inside is just perfect. Fresh, moist, and springy with fresh fruit or cream filling that's the perfect sweetness. I've tried almost every cake in San Mateo and below, and this is one of the best!

    Ordered Claire's crunch cake and got the strawberry one. These cakes are quite hefty and very dense. The crunch part of itself is pretty sweet however, it balance as well with the rest of the cake that is not as sweet. The strawberry frosting inside did not really taste as much strawberries as I would've liked, but that's fine. I also really like the giant full strawberries inside of the cake. The cake was moist and delicious. It is definitely a good idea to try to eat as much as the cake as you can because the next day the crunch pot melts. I would recommend people to try this and would like to try the mocha flavor next time.

    Thank you for the AMAZING cake!!! I have had Claire's Crunch Cakes in my bookmarks for a long time and just hadn't had a chance to try it. I wasn't sure how to order so on a previous birthday celebration, I tried calling but I couldn't get a hold of anyone and their VM was full (must be very high demand)! I didn't want to just show up since I had no idea how it worked and whether they would have any cakes without ordering ahead. The next time someone's birthday was coming up I decided I wanted to surprise them with this cake but wanted to be sure I could get my hands on one so I called in about a month ahead, this time a gentleman answered and we got all the details down. On the day of pick up, I arrived and you can immediately smell the goodness from outside! Sadly, they said they didn't have my name down for an order? The gentleman said no problem, they have people show up without an order all the time, although his advice is calling in about a week ahead to ensure everything is set for time of pick up. They asked me if I was okay with waiting about 10 minutes so I did. I am glad that it worked out because the cake was really good! The crunchy pieced are perfectly sweet and salty, they compliment the buttercream and the very rich cake very well! I'm not sure how long they keep that texture as the gentleman did advise to eat the cake as soon as possible, as the crunchy pieces likely won't stay fresh overnight. I did try some right away and then had some more a few hours later and the texture remained great even after a few hours! I will definitely return again-also now I know the whole shpiel with how to order, so I am excited to celebrate future birthdays with Claire's cakes!

    Do you have a cookies and cream crunch cake?

    Reena, No, we don't have a cookies and cream crunch cake!

    Is it possible to get a chocolate strawberry crunch cake?

    Absolutely! The cost is $65 and it is delicious! Call and reserve it for your family and or event. I need date and time. Call 650 344-8690!

    Can you make a semi-sweet cake? Thanks!

    JL, my crunch cakes are not sweet! If you put the crunch on yourself, they will be even less sweet. The crunch is the sweetest part of the cake. You can call at 650 344-8690.

    Is it possible to request the cake lighter more like sponge cake? The cake portion is really dense.

Order via worker standing behind the counter. Cookies: The 66% chocolate chip had big chunks of chocolate which the bitterness helped balance the cookie. The cookies n cream was a little sweet for me but had again pieces of Oreos inside with a nice texture. The chocolate peanut butter again had both chocolate and creamy peanut butter which didn't leave the mouth dry. The honey comb was a unique and different taste with the honeycomb providing a less common sweetness but can be overpowering. The toffee cookie had bits of toffee which again provided texture without being overly sweet. The oatmeal chocolate walnut cookie was my second favorite after the 66% dark cocoa due to the oatmeal again balancing the sweetness of the chocolate with the saltiness of the walnuts. Overall would recommend for a solid cookie with a fair price and the day olds were also extremely cheap for a better quality than you could get at other places.

We came on a Saturday around 7pm and there was no line but the place was lively, we got lucky and didn't have to wait, probably because most people were still at dinner. Fork ordered: Tiramisu and a latte The latte was good. Nothing to get excited over, but well made. The tiramisu is a standout. It has this nice crunchy chocolate shell on the outside with a smooth, creamy center and just the right hint of coffee. As a tiramisu fiend, this is one I'd absolutely come back for. Spoon ordered: French flan I don't usually go for flan, but this one is different!!! I do absolutely love the custard layer in a fruit tart, so imagine that with a firmer texture and a richer vanilla flavor. It sits in this perfectly thin, almost hidden pie-like crust. It's honestly divine and highly recommended. Before we leave, we typically get a treat for the next morning to have with our chai. I love the banana bread and Fork goes for the croissant. Overall, such a charming spot for dessert and coffee, especially if you can grab a table outside.
