I predict this dessert of Zora's will become a vegan standard, and an instant classic. Rather than repeat what I wrote here, I'll just refer you to the comments section of the recipe on food52.com. Zora just wrote on Facebook that the dessert has become a semi-finalist.
I had no knowledge that this dessert even existed until three nights ago, and Zora has no idea I'm writing this. My comments on the website reflect genuine enthusiasm for this impossibly simple, impossibly rich, impossibly chocolatey masterpiece.
