I recently tried Lark Bake Shop, and frankly didn’t love it. I felt the cake was dry. I’ve had Republique’s, and came away wishing it was a bit lighter and more caramel, loss chocolate, but it was still quite good.
From an old Chowhound post, I see that the Palm Restaurant’s multilayer chocolate cake comes from a business called Sweet Treats Bakery. Not sure of the location, though I seem to recall Freeport, PA (we bought an entire cake during the first month of lockdown).
Bumping this topic. Also looking for a delicious chocolate cake for my daughters birthday. Sweet Lady Jane and Susie Cakes are close along with Doan’s but I don’t mind traveling to pick it up and I’m not against ordering on Goldbelly.
You could pick up SusieCakes a day or two before and keep it refrigerated and it’ll hold up well. Just follow the instructions and set it out to come to temperature.
I don’t know about the best in LA but it’s pretty reliable and my style, which is to say dark (black) and dense- Jon & Vinny’s. It’s mostly for when I’m in need of cake at night (why there are no decent cake spots open after 4pm in the area I will never understand) and when I’m not going there for cookies. Republique’s and Proof’s are fine but I’m not always in the mood for caramel and I’m not a fan of espresso… I usually just want chocolate as is with the only variable being the frosting as sometimes I like white frosting. J&V’s is a luscious chocolate on chocolate that comes with a side of vanilla bean creme anglaise.
