An old Brooklyn classic, Blackout Cake is an ultra chocolaty, custardy, cake-crumb-coated dessert with somewhat mythic status. Gale Gand created a version upon request for a client's 70th birthday and now it's become one of her most obsessed-over signatures. "I said, 'Well, I’ve never had it, but I have friends who grew up in New York, and they’ve had it,'" Gand says. "So I did some research, made it, and ran it by my friends and their parents to get feedback, and then I tweaked it. Then I did that again and again until I finally—apparently—got it exactly right. So now I get all these calls—it's like a drug deal—and people say, 'I hear you do Blackout Cake.' I say, 'Where’d you hear that? How do you know that?' If you Google blackout cake, my name pops up."
