Ingredients You’ll Need
Gathering your ingredients might feel like assembling a dream team for chocolate perfection. Each component is simple yet essential, contributing to the layered complexity of flavor and texture that defines the Brooklyn Blackout Cake Recipe.
- 2 cups all-purpose flour: The base that holds all the chocolatey goodness together with a tender crumb.
- 2 cups granulated sugar: Sweetens the cake and pudding just right, balancing the cocoa’s natural bitterness.
- ¾ cup unsweetened Dutch-process cocoa powder: Provides rich, smooth chocolate flavor and a dark color that’s unmistakably decadent.
- 2 tsp baking soda: Helps the cake rise and gives it a light texture despite its richness.
- 1 tsp baking powder: Works alongside baking soda for perfect lift and softness.
- ½ tsp salt: Enhances the sweetness and deepens the chocolate flavor in every bite.
- 1 cup buttermilk, at room temperature: Adds moistness and a subtle tang, balancing sweetness beautifully.
- ½ cup vegetable oil: Keeps the cake moist and tender, avoiding dryness.
- 2 large eggs, at room temperature: Bind everything together, adding structure and fluff.
- 2 tsp pure vanilla extract: Brings warmth and depth to the chocolate notes.
- 1 cup hot brewed coffee: Intensifies the chocolate flavor without tasting like coffee at all.
- 2 ½ cups whole milk: The creamy base for the pudding filling.
- ¾ cup granulated sugar: Sweetens the pudding to complement the cake layers.
- ¼ cup unsweetened cocoa powder: Adds chocolate richness to the pudding.
- ¼ cup cornstarch: Thickens the pudding to the perfect custard-like consistency.
- ¼ tsp salt: Balances flavors in the pudding.
- 4 oz semisweet chocolate, finely chopped: Melts into the pudding filling, creating silky chocolate bursts.
- 1 tsp pure vanilla extract: Enhances the filling’s flavor profile.
- 8 oz semisweet chocolate, finely chopped: The star ingredient for the luscious frosting.
- 1 cup heavy cream: Makes the frosting smooth and rich.
- 2 tbsp light corn syrup: Gives the frosting a glossy finish and keeps it stable.
- 1 tsp pure vanilla extract: Adds a hint of warmth and rounds out the frosting’s flavor.
How to Make Brooklyn Blackout Cake Recipe
Step 1: Prepare the Cake Layers
Start by preheating your oven to 350°F (175°C), then grease and flour two 9-inch round cake pans, lining the bottoms with parchment paper for easy removal. Sift together the flour, sugar, cocoa powder, baking soda, baking powder, and salt in a large bowl. In a second bowl, whisk the buttermilk, vegetable oil, eggs, and vanilla extract until smooth. Gradually combine the wet ingredients with the dry, mixing just until incorporated — overmixing can make the cake dense. Stir in the hot brewed coffee carefully; the batter will be thin, but that’s normal and key for moistness. Divide this batter evenly between the pans and bake for 30-35 minutes. A toothpick inserted in the center should come out clean when done. Allow the cakes to rest in the pans for 10 minutes before transferring to a wire rack to cool completely.
Step 2: Make the Chocolate Pudding Filling
While the cakes cool, whisk together the milk, sugar, cocoa powder, cornstarch, and salt in a saucepan until smooth, avoiding any lumps. Place the saucepan over medium heat, stirring constantly to prevent scorching. As it heats, the pudding will thicken and bubble—when this happens, remove it from the heat immediately. Stir in the chopped semisweet chocolate and vanilla extract until the mixture is silky and smooth. To avoid a skin forming on the pudding, press plastic wrap directly onto its surface, then refrigerate until fully chilled. This pudding adds that creamy, velvety texture that makes this Brooklyn Blackout Cake Recipe so memorable.
Step 3: Prepare the Chocolate Frosting
Place the chopped semisweet chocolate into a heatproof bowl. Heat the heavy cream and corn syrup in a small saucepan over medium heat until it just begins to simmer. Pour the hot cream mixture over the chopped chocolate and let it sit undisturbed for 2-3 minutes to soften the chocolate. Then, stir until the mixture is smooth and glossy. Add the vanilla extract and set the frosting aside to cool, stirring occasionally. You’ll know it’s ready to use when it thickens to a spreadable texture perfect for coating your cake.
Step 4: Assemble the Cake
Using a serrated knife, level the cake tops if they have domed. Cut each cake horizontally into two even layers so you end up with four layers total. Save one layer to crumble later for decorating the cake. Place the first cake layer on your serving plate and spread a generous third of the chilled pudding over the top. Repeat the layering and pudding spreading two more times, ending with the final cake layer on top. Frost the entire cake with the chocolate frosting, smoothing it over the sides and top. Finally, crumble the reserved cake layer finely and press the crumbs onto the frosting, covering the whole cake with that signature blackout crumb coating.
Step 5: Chill and Serve
Refrigerate your masterpiece for at least one hour before slicing to let the layers set and the flavors meld together. When you’re ready, cut yourself a generous slice of this moist, decadent Brooklyn Blackout Cake Recipe and savor the indulgence!
How to Serve Brooklyn Blackout Cake Recipe
Garnishes
To add a little extra flair, consider garnishing with dark chocolate curls or a dusting of cocoa powder to enhance the cake’s luxurious chocolate theme. Fresh berries like raspberries can provide a pop of color and a touch of tartness that beautifully offsets the richness.
Side Dishes
This cake shines on its own but pairs wonderfully with simple sides like a scoop of vanilla bean ice cream or a drizzle of raspberry sauce. A cup of strong black coffee or rich espresso also matches beautifully, echoing the coffee notes baked into the cake.
Creative Ways to Present
For special occasions, consider serving this cake on a rustic wooden platter or a sleek black cake stand to accentuate its deep chocolate tones. Slice the cake into smaller squares for a lovely bite-size dessert at parties or layer into individual glass containers for elegant single servings.
Make Ahead and Storage
Storing Leftovers
This Brooklyn Blackout Cake Recipe keeps beautifully in the refrigerator for 3-4 days. Make sure to cover it tightly with plastic wrap or store it in an airtight container to preserve its moisture and prevent it from absorbing other fridge odors.
Freezing
If you want to enjoy this cake later, you can freeze it for up to 2 months. Wrap the cake tightly in plastic wrap and then a layer of aluminum foil to protect it from freezer burn. Thaw it overnight in the refrigerator before serving.
Reheating
Because this cake is best enjoyed chilled, reheating isn’t necessary. If you prefer your cake closer to room temperature, simply let slices sit out for about 15-20 minutes before eating to soften the frosting slightly and release the complex chocolate flavors.
FAQs
What makes a Brooklyn Blackout Cake different from a regular chocolate cake?
The Brooklyn Blackout Cake stands out because of its layers filled with rich chocolate pudding and coated with chocolate cake crumbs, giving it a uniquely moist texture and deep chocolate impact beyond a standard chocolate layer cake.
Can I use regular cocoa powder instead of Dutch-process cocoa?
While you can substitute regular cocoa powder, Dutch-process cocoa is preferred because it has a smoother flavor and darker color, which better suits the intense chocolate profile of a Brooklyn Blackout Cake Recipe.
Is the hot coffee flavor noticeable in the cake?
Not at all! The hot coffee enhances and deepens the chocolate flavor without imparting a coffee taste, making the cake richer and more complex.
Can I make this cake gluten-free?
To adapt this Brooklyn Blackout Cake Recipe for gluten-free diets, use a gluten-free flour blend designed for cakes. Be sure to check the blend contains xanthan gum for structure.
How do I prevent the pudding from forming skin while chilling?
Pressing plastic wrap directly onto the surface of the pudding while it cools is key to preventing skin formation, keeping the filling amazingly smooth and creamy.

There’s something truly special about the Brooklyn Blackout Cake Recipe that turns a simple chocolate craving into an unforgettable experience.

For the Chocolate Frosting:
- 8 oz semisweet chocolate, finely chopped
- 1 cup heavy cream
- 2 tbsp light corn syrup
- 1 tsp pure vanilla extract
Instructions
- Prepare the Cake Layers: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans and line the bottoms with parchment paper for easy removal. In a large bowl, sift together the flour, sugar, cocoa powder, baking soda, baking powder, and salt. In a separate bowl, whisk the buttermilk, vegetable oil, eggs, and vanilla extract until combined. Gradually mix the wet ingredients into the dry ingredients until just combined, then stir in the hot brewed coffee until the batter is smooth and thin. Evenly divide the batter between the prepared pans. Bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean. Let the cakes cool in the pans for 10 minutes, then transfer to wire racks to cool completely.
- Make the Chocolate Pudding Filling: In a medium saucepan, whisk together the whole milk, sugar, cocoa powder, cornstarch, and salt until smooth. Place over medium heat and cook, stirring constantly, until the mixture thickens and begins to bubble. Remove from heat and stir in the chopped semisweet chocolate and vanilla extract until fully melted and smooth. Transfer the pudding to a bowl and cover with plastic wrap directly on the surface to prevent a skin from forming. Refrigerate until completely chilled.
- Prepare the Chocolate Frosting: Place the chopped semisweet chocolate in a heatproof bowl. In a small saucepan, heat the heavy cream and corn syrup over medium heat until it begins to simmer. Pour the hot cream mixture over the chopped chocolate and let sit for 2 to 3 minutes to melt. Stir gently until smooth, then stir in the vanilla extract. Allow the frosting to cool while occasionally stirring until it reaches a spreadable consistency.
- Assemble the Cake: Using a serrated knife, level the tops of the cooled cakes if necessary. Cut each cake horizontally into two even layers, creating four layers total. Reserve one of these layers and crumble it finely to use as a cake coating. On a serving plate, place one cake layer and spread one-third of the chilled chocolate pudding filling evenly over it. Repeat the process with two more layers, spreading the pudding filling between each. Place the final cake layer on top. Frost the entire cake with the prepared chocolate frosting, covering top and sides smoothly. Press the reserved cake crumbs gently onto the frosting all around the cake to finish.
- Chill and Serve: Refrigerate the assembled cake for at least one hour to set and meld the flavors. Slice carefully and enjoy this indulgent, rich chocolate masterpiece with family and friends.
