I think she tried to keep the cakes somewhat similar. I’m going to date myself – I actually call that vegan cake an Amazon cake (can’t remember why.) I’ve never had it come out well, but I was just watching Ep. 4 of King Arthur’s Isolation Bakeoff and they had a similar cake. I need to tackle it again and figure out what I’m doing wrong.
She actually lists the exact ingredients she uses, so with a some effort you can get results close to hers. In my experience, if you choose the best on her list and get your ingredients as close as possible, you will do very well serving it to the average eater.
These days, I keep coming back to this recipe from Dorie Greenspan. (Alternate link to half recipe.)
