How to Make Brooklyn Blackout Cake
-
Prepare the Cake: Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans with butter or non-stick spray. Flour the pans lightly to prevent sticking.
-
Mix Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, natural cocoa powder, baking powder, baking soda, and salt until well combined, ensuring even distribution of the leavening agents.
-
Mix Wet Ingredients: In a separate bowl, whisk together the large eggs, egg yolk, buttermilk, melted unsalted butter, and vanilla extract. Mix until smooth, and allow to rest for a few minutes.
-
Combine Mixtures: Carefully fold the wet ingredients into the dry ingredients, mixing at low speed until just combined. Gradually add the hot brewed coffee, creating a thin batter that’s rich and chocolatey.
-
Bake the Cakes: Divide the batter evenly between the prepared pans. Bake for 30-35 minutes until a toothpick inserted in the center comes out clean. Let them cool in pans for 10 minutes before inverting onto a wire rack to cool completely.
-
Make Chocolate Pudding Filling: In a medium saucepan, whisk together the egg yolks, granulated sugar, cornstarch, and salt until pale. Gradually add the heated cream and water, cooking over medium heat until the mixture thickens. Once thickened, transfer to a bowl, cover, and refrigerate for at least 2 hours.
-
Prepare Chocolate Frosting: Melt the unsweetened chocolate gently, then beat the softened unsalted butter until creamy. Gradually mix in the sifted confectioners’ sugar and vanilla extract, blending until smooth and fully combined with the melted chocolate.
-
Assemble the Cake: Once cooled, cut each cake layer in half horizontally to create four layers. Place one layer on a stand or platter, top with chocolate pudding filling, and repeat layering. Frost the entire cake with the chocolate frosting, ensuring smooth coverage.
-
Add Cake Crumbs: Take any leftover cake scraps and crumble them into fine crumbs. Press these crumbs onto the frosted surface for a decorative touch.
-
Serve: Chill the assembled cake slightly before serving to enhance the flavors. It’s best enjoyed at room temperature and can be stored loosely covered in the fridge for up to 2 days.

Brooklyn Blackout Cake Recipe FAQs
How do I select the right cocoa powder for my Brooklyn Blackout Cake?
I recommend using natural cocoa powder for the best flavor and texture in your cake. Avoid Dutch-processed cocoa as it can alter the cake’s final outcome. To ensure freshness, check the expiration date on the package, and store your cocoa in a cool, dry place.
What’s the best way to store my Brooklyn Blackout Cake?
To keep your cake moist, loosely cover it with parchment paper and store it at room temperature for up to 1 day. If you have leftovers, place them in the refrigerator for up to 2 days. This helps maintain the cake’s rich flavor and moisture.
Can I freeze Brooklyn Blackout Cake layers?
Absolutely! Wrap each cooled cake layer tightly with plastic wrap, then cover with aluminum foil. You can freeze them for up to 3 months. When you’re ready to use them, thaw the layers in the refrigerator overnight before frosting. This way, they’ll be ready to assemble without losing quality.
What should I do if my cake layers are puffing up too much in the center?
If you notice that the cake layers are doming excessively, it could be due to overly high oven temperature or overmixing the batter. I recommend using an oven thermometer to ensure your oven is at the correct temperature, and mix your batter just until combined to maintain a tender crumb. If the cake is domed, simply use a serrated knife to level them off after baking.
Are there any dietary considerations I should keep in mind for this recipe?
If you’re baking for guests with allergies, note that this recipe contains eggs and gluten. You can swap out all-purpose flour for almond flour for a gluten-free option, adjusting the liquid ratios as necessary. For a dairy-free version, consider using plant-based butter and a non-dairy milk alternative mixed with vinegar instead of buttermilk.
Can I use this recipe for other cake variations?
Yes! You can certainly experiment by adding flavored liqueurs instead of coffee or using dark chocolate instead of semisweet chocolate for a richer taste. Feel free to customize the cake to suit your preferences, making it uniquely yours while still enjoying the essence of the Brooklyn Blackout Cake!
