★ 5★ 4★ 3★ 2★ 1I was looking for a bakery to get my mom’s birthday cake from and came across Claire’s crunch cakes. Decided to try them out, got two cakes- one lemon and one mocha. They were amazing! We all loved them. The outside crunchy bit absorbs some flavor from the cake and was to die for! The cake itself was moist and delicious, not overly sweet. I preferred the lemon, although both were amazing! None of us had ever had a cake quite like it and our family is thrilled to have found a new favorite cake spot. Thank you Claire.
January 10 · Laura SullivanFirst time ordering a crunch cake! We got the 6” inch strawberry crunch cake and called in the order a day before to pick up. Parking is limited since it’s a residential street. When I arrived for pick up, they were just putting the brittle on. The cake is very unique, the strawberry crunch had brittle crumble all over the outside and in the inside are two moist cake and a thick layer of cream and fresh strawberries.The cake is not that sweet and taste amazing with the brittle crunch. Cutting it wasn’t that difficult, I wiped the knife each slice as instructed. I would order the mocha cake next time! This cake is $35, cash only.
October 13 · LoI ordered the 6" Mocha Crunch Cake ($30) and everyone loved it. Good size for a party of 8 to each sample a slice. The best part are the crunchy bits! She only accepts phone calls but right at 5:00PM they stop answering so be sure to call on time. Luckily she was able to accept my order with a 1-day notice. Pick-up is at her house and there are usually parking spots in the residential area. She's very direct and doesn't do small talk. I asked if it needed to be refrigerated and she said bluntly, "It's on the box."
December 12 · Vanessa CheungSo delicious! I ordered a 6inch strawberry crunch cake and it was the perfect size for 3-5 people. The crunch is amazing. Claire was able to accommodate my request within less than a 24hr notice. She makes a fantastic cake and I highly recommend her small business! Oh and she sold me an awesome candle to go along with the cake!
March 22 · Lisa LThe strawberry crunch cake is exquisite. I would come back for a second and I'm not a fan of sweets. The cake itself isn't that sweet at all, with generous strawberry fillings. Most of the sweetness comes from the crunch, which kind of reminds me of a meringue (soft and light).
