This loaf cake comes together quickly and easily, and boasts a remarkably deep color, intensely rich flavor and a plush, velvety crumb. The recipe came to us by way of Claire Ptak, of Violet Cakes, a bakery-café in East London. To achieve the cake’s deep, complex chocolatiness, she uses a generous amount of bittersweet chocolate and unsweetened cocoa powder. Any type of bittersweet chocolate will work, but we recommend using one that’s tasty enough to eat out of hand and contains about 70 percent cocoa solids. Serve slices with spoonfuls of crème fraîche, which has a subtle tang and creaminess that are fantastic foils for the cake. Store leftovers at room temperature, tightly wrapped, for up to three days.

Tip

Don’t use natural cocoa. Dutch-processed is best because the alkali used in its production gives the cocoa a richer, deeper hue and smoother taste that’s important for color and flavor intensity. If your cocoa does not indicate type on the label, check the ingredient list. If it reads “processed with alkali,” the cocoa is Dutch-processed.

Fun to make
Turned out just like the photo with a very thin crust on top. I substituted semisweet chocolate chunks and 85% cacao dark chocolate. Lovely with a dollop of creme fresh.

Simple, Delicious
Easy to put together, very moist, dark chocolate flavor that is none too sweet.

Sublime
I baked this yesterday and I'm in love with this cake! I followed the directions exactly and it came out perfectly with a moist crumb and sophisticated flavor. I left it out overnight wrapped in plastic and sliced it today. Heavenly. My oven runs hot so I baked 55 minutes and then left in pan for the full 20 minutes. The center slices around the top had a tiny bit of fudgy texture but delicious. I think the risk of overcooking this is high so it's a fine line and I wouldn't cook it any longer than an extra minute, if any at all.

Excellent
I made this exactly as written - baked it for 55 minutes - tested it and determined to bake another few minutes. The cake had a very nice chocolate taste/flavor - I think the carryover cooking (20 minutes in the pan) might have been too long as I think it would have been more moist. Next time, I likely would take it out of the pan after maybe 10 minutes. I didn’t serve it with crème fraiche but think that might have been a nice addition/balance. Also, don’t know whether substituting Greek yogurt for the water might result in a less dense/tight crumb. Very easy to make and the aroma in the house was fantastic.
