I made this for Passover and it did not take me 5hrs. I skipped the caramel sauce and used a purchased goat milk caramel sauce( from Williams Sonoma). The cake was excellent. Intense, rich chocolate flavor( please use good chocolate) and the date puree was a good choice. It did not overpower the cake, it added a nice subtle sweetness.
Seeing the photo for this in the magazine really drew me in!
Definitely take note of the time required. I don't think it took me 5 hours, but it probably took at least 3.
The cake turned out lovely, like the picture, and had a light, delicate almost mousse-like texture.
If I made it again, I would do a different glaze. A more intense flavor such as chocolate, berry, etc. Only make this if you do have astand mixer and a pastry brush! I didn't have a brush and making the caramel was tricky!
