Instructions
Prepare Cake Pans
Butter two 8‑inch cake pans, line with parchment rounds, then dust lightly with cocoa powder using a pastry brush.
Time: PT5M
Sift Dry Ingredients
In a large bowl sift together the all‑purpose flour, Dutch‑process cocoa powder, baking powder, baking soda, and kosher salt.
Time: PT5M
Mix Wet Ingredients
In another bowl whisk the whole egg, extra yolk, vanilla extract, vegetable oil, and dark brown sugar until smooth and no sugar lumps remain.
Time: PT5M
Combine and Bloom Cocoa
Add the wet mixture to the dry ingredients, then slowly whisk in hot water until the batter is glossy and the cocoa is fully bloomed.
Time: PT5M
Bake Cake Layers
Divide the batter evenly between the two prepared pans. Bake at 350°F for 30 minutes, or until a toothpick comes out clean.
Time: PT30M
Temperature: 350°F
Prepare Pudding Thickener
In a saucepan whisk together Dutch‑process cocoa powder and cornstarch until combined.
Time: PT2M
Make Chocolate Pudding
Add heavy cream, whole milk, 4 egg yolks, dark brown sugar, and a pinch of salt to the cocoa‑cornstarch mixture. Cook over medium‑high heat, stirring constantly, until it reaches a boil, then reduce to low and whisk for 2 minutes until smooth. Strain through a fine mesh sieve into a bowl.
Time: PT10M
Chill Pudding
Cover the pudding with plastic wrap pressed directly onto the surface to prevent a skin. Refrigerate for 4 hours until very cold.
Time: PT4H
Make Ganache Frosting
In a saucepan bring heavy cream, a pinch of salt, and golden syrup to a boil. Remove from heat and whisk in dark chocolate, sour cream, and butter until fully melted and glossy.
Time: PT5M
Cool Frosting
Transfer the ganache to a bowl, let it sit at room temperature for 1.5 hours, stirring every 30 minutes until it thickens to a spreadable consistency.
Time: PT1H30M
Level and Crumble Cake Layers
Trim the tops of the baked cakes to make them flat. Reserve one layer for crumb coating; crumble it finely by hand or with a grater.
Time: PT10M
Assemble Cake with Pudding
Place the first cake layer on a board, spread half of the chilled pudding evenly, then top with the second layer (pudding side down). Chill the assembled stack for 1 hour to set the filling.
Time: PT15M
Apply Ganache Frosting
Using an offset spatula, coat the top and sides of the chilled cake with a thin crumb coat of frosting, then roll the cake in the reserved chocolate crumbs. Finish with a smooth final layer of ganache.
Time: PT20M
Final Chill and Serve
Refrigerate the finished cake for 30 minutes to set the frosting, then remove parchment, slice with a hot, sharp knife, and serve.
Time: PT30M

Frequently Asked Questions
What is the cultural significance and history of Blackout Cake in Brooklyn cuisine?
Blackout Cake originated at the historic Evan Jers bakery in Brooklyn, opened in 1906. During World War II the bakery turned off its lights to keep ships leaving New York Harbor undetected, giving the cake its name. It became a beloved local treat, symbolizing resilience and indulgence in wartime Brooklyn.
What are the traditional regional variations of Blackout Cake in American cuisine?
While the classic Brooklyn version uses a dense devil’s food cake, some New York bakers add espresso or coffee to deepen the chocolate flavor. In other parts of the U.S., variations replace the chocolate pudding filling with a coffee‑infused mousse or use a buttercream instead of ganache.
How is Blackout Cake traditionally served in Brooklyn celebrations?
In Brooklyn, Blackout Cake is often served at birthdays, bar mitzvahs, and holiday gatherings. It is sliced into generous wedges and paired with a strong cup of coffee or a glass of milk, letting the rich chocolate shine.
What occasions or celebrations is Blackout Cake traditionally associated with in American culture?
Beyond its wartime origins, Blackout Cake is a popular choice for birthday parties, graduation celebrations, and festive holiday desserts throughout the United States, especially in the Northeast where its Brooklyn roots are celebrated.
How does Blackout Cake fit into the broader American chocolate cake tradition?
Blackout Cake represents an elevated version of the classic American chocolate cake, adding layers of chocolate pudding and a glossy ganache frosting. Its richness and multi‑textured layers set it apart from simpler buttercream‑frosted cakes, showcasing the American love for indulgent, layered desserts.
What are the authentic traditional ingredients for Blackout Cake versus acceptable substitutes?
Authentic ingredients include Dutch‑process cocoa, dark brown sugar, heavy cream, and a chocolate ganache made with dark chocolate and golden syrup. Acceptable substitutes are natural cocoa (add a bit more), light brown sugar, half‑and‑half for cream, or maple syrup in place of golden syrup, though flavor will shift slightly.

What makes Blackout Cake special or unique in American chocolate cake cuisine?
Its unique combination of a dense devil’s food cake, a thick chocolate pudding filling, and a glossy ganache frosting creates a multi‑layered texture rarely found in typical American chocolate cakes, delivering both moist crumb and silky filling in each bite.
What are the most common mistakes to avoid when making Blackout Cake at home?
Common mistakes include over‑baking the cake, which dries it out; not straining the pudding, leading to a gritty texture; and failing to cover the pudding with plastic, which creates an unwanted skin. Follow the timing and cooling steps carefully for best results.

Cocoa powder adds a dark, chocolatey edge to the cake and prevents a floury taste on the crust. It also reinforces the chocolate flavor and gives the finished cake a sleek, professional appearance.
Can I make Blackout Cake ahead of time and how should I store it?
Yes. Bake and cool the cake layers up to two days ahead, store them wrapped at room temperature. The pudding can be made a day ahead and kept refrigerated. Assemble the cake no more than a few hours before serving, then keep the finished cake refrigerated.
