A deeply satisfying chocolate experience awaits in this simplified version of Brooklyn's iconic blackout cake. This homestyle adaptation delivers intense chocolate flavor through its moist, tender crumb and cloudlike whipped ganache frosting, making it an irresistible dessert that honors the original's decadent spirit while being achievable in any home kitchen.
After making this cake countless times in my kitchen, I've found it's the perfect balance between special occasion worthy and everyday achievable. The look of pure joy on my chocolate-loving husband's face when he sees this cooling on the counter is priceless.
Essential Ingredients Selection
- Cocoa Powder: Choose Dutch-processed cocoa for a smoother, deeper chocolate flavor. Natural cocoa works too but produces a slightly different taste profile
- Chocolate: Select high-quality bar chocolate with 60-70% cacao content. Avoid chocolate chips as they contain stabilizers that affect the ganache texture
- Sour Cream: Full-fat sour cream provides moisture and tanginess that enhances the chocolate flavor
- Brown Sugar: Light or dark brown sugar adds moisture and subtle caramel notes that complement the chocolate
Detailed Preparation Steps
- Perfecting the Ganache
- Chop chocolate into uniform pieces no larger than a pea for even melting
- Heat cream just until steaming - bubbling cream can make the ganache grainy
- Let chocolate and cream sit undisturbed before whisking to prevent separation
- Mastering the Cake Batter
- Bloom cocoa powder thoroughly until mixture is completely smooth
- Maintain ingredients at room temperature for even mixing
- Fold dry ingredients gently to avoid developing gluten which can make the cake tough
- Achieving the Perfect Texture
- Watch cake carefully in final baking minutes - overbaking can dry out edges
- Cool cake completely before frosting to prevent ganache from melting
- Whip ganache only after it reaches proper consistency for best results

Growing up in New York, the original Brooklyn Blackout Cake was legendary. While developing this recipe, I focused on capturing that same intense chocolate experience while simplifying the process.
The beauty of this cake lies in its versatility - it's equally at home at a casual family dinner or dressed up for a special celebration.
This recipe proves that sometimes the simplest approach yields the most satisfying results. The single layer with whipped ganache allows the pure chocolate flavor to shine.
Each slice offers a perfect balance of tender cake and creamy frosting, making it impossible to resist going back for seconds.
After years of baking chocolate cakes, this version stands out for its perfect balance of richness and simplicity. It's become my go-to recipe when I want to share something special with chocolate lovers in my life.
Creative Serving Ideas
Transform this classic chocolate cake into an elegant dessert by serving it with fresh raspberries or a dusting of cocoa powder. For special occasions, I've found that edible gold leaf adds a stunning contrast against the dark chocolate. During summer gatherings, a scoop of vanilla bean ice cream creates the perfect temperature contrast with the dense, rich cake.
Make-Ahead and Storage Solutions
The beauty of this cake lies in how it develops deeper flavors over time. Make it a day ahead for the best taste - the chocolate notes become more pronounced and complex. If storing longer, individual slices can be wrapped and frozen for up to three months. Just thaw in the refrigerator overnight when the chocolate craving strikes.

Variations Worth Trying
The basic recipe welcomes creative twists while maintaining its decadent character. Add a teaspoon of espresso powder to the batter for a mocha version, or stir in some orange zest for a chocolate-orange combination. I've even added a layer of raspberry preserves beneath the ganache for special occasions.
Troubleshooting Common Issues
If your ganache seems too firm to whip, warm it gently in 5-second microwave bursts, stirring between each until it reaches the right consistency. For cake that seems dry, brush layers with simple syrup before frosting. If the cake develops a slight dome while baking, simply trim it level before frosting.
Historical Background
While this version simplifies the original Brooklyn Blackout Cake, it maintains the spirit of the beloved dessert that originated at Ebinger's Bakery. The original version, with its dark chocolate cake, pudding filling, and cake crumb coating, was named after the blackout drills during World War II.
