Meanwhile, here is the winning cake recipe. It comes from America's Test Kitchen for a cake from a Brooklyn (NY) bakery that went out of business, which boggles the mind as it sold this cake.
Chocolate Blackout Cake
From the episode: Forgotten Cake, America’s Test Kitchen

Note: Be sure to give the pudding and the cake enough time to cool or you’ll end up with runny pudding and gummy cake.

[Mrs. BA would like to point out here that when she was making the pudding - the 2-4 minutes that are mentioned is really more like 18-20.]
For the cake layers: Adjust oven rack to middle position and heat oven to 325 degrees. Butter and flour two 8-inch cake pans. Whisk flour, baking powder, baking soda, and salt in bowl.
Melt butter in large saucepan over medium heat. Stir in cocoa and cook until fragrant, about 1 minute. Off heat, whisk in coffee, buttermilk, and sugars until dissolved. Whisk in eggs and vanilla, then slowly whisk in flour mixture.
Divide batter evenly between prepared pans and bake until toothpick inserted in center comes out clean, 30 to 35 minutes. Cool layers in pans 15 minutes, then invert onto wire rack. Cool to room temperature, at least 1 hour.
To assemble the cake: Cut each cake in half horizontally. Crumble one cake layer into medium crumbs and set aside. Place one cake layer on serving platter or cardboard round. Spread 1 cup pudding over cake layer and top with another layer. Repeat with 1 cup pudding and last cake layer. Spread remaining pudding evenly over top and sides of cake. Sprinkle cake crumbs evenly over top and sides of cake, pressing lightly to adhere crumbs. Serve. (Cake can be refrigerated for up to 2 days.)
