There was a foolproof recipe in a Queer Eye for the Straight Guy self-help book (don't ask, don't tell) for this easily veganized brownie dessert. It was shiny-topped brownie cake floating on top of warm, mocha pudding, the kind where you sprinkle a sugar mix on top of the batter and then pour coffee over it all before baking. No eggs, no mess. Except on one's face after eating.
That book is in storage thousands of miles away, but if anyone can post a similar recipe I'd be much obliged.
