Bring a taste of Brooklyn to your home with this over-the-top chocolate cake that's got an amazingly soft texture and creamy whipped ganache. This easier version of the famous blackout cake packs tons of chocolate goodness without any fancy techniques or weird ingredients you can't find.

I've tried over twenty chocolate cake recipes, and this one always gives the best results without much work. The whipped ganache turns into this fluffy topping that's way easier to handle than regular buttercream.

Key Components:

  • Good cocoa powder - Dutch-processed gives you darker color and better taste
  • Brown sugar - makes it juicier with hints of caramel
  • Sour cream - keeps everything soft and moist
  • Chocolate bars - don't use chips if you want smooth ganache
  • Hot coffee - makes chocolate taste better without adding coffee flavor

Step-by-Step Guide:

Nail Your Ganache
  • Cut chocolate into small same-sized bits for better melting
  • Warm cream until it steams - if it bubbles, it's too hot
  • Don't touch the chocolate at first after adding cream
  • Let it cool on the counter, checking how thick it gets
Mix Your Batter Right
  • Stir cocoa in hot liquid until it's completely smooth
  • Beat wet stuff until it looks uniform
  • Mix in dry ingredients softly to keep cake tender
  • Bang pan on counter to get air bubbles out
Bake It Just Right
  • Put rack in middle of your oven
  • Turn pan around halfway through baking
  • Look for cake pulling away from pan sides
  • Stick toothpick in several spots to check if it's done

My grandma always put a tiny bit of espresso powder in her chocolate cake to make the chocolate taste stronger - I've done the same thing here and it works great.

Picking The Right Chocolate:

After baking for years, I've found that chocolate quality really changes how your cake turns out. I like using chocolate with 60-70% cacao because it's got the right mix of sweetness and strong chocolate flavor.

Getting Temperatures Right:

When I worked as a pastry chef, I learned that chocolate is all about getting the heat just right. Your ganache should be cool enough to hold shape but warm enough to spread easily.

This Brooklyn Blackout Cake has become the dessert I'm known for. The mix of rich chocolate flavor with that cloud-soft whipped ganache makes a dessert people won't forget and always want the directions for.

How To Nail Whipped Ganache

After making tons of batches, I found that the trick to amazing whipped ganache is all about when you whip it. It needs to cool until it makes a soft peak when you lift your spoon - usually after sitting out for about 30 minutes. This gives you frosting that goes on smooth and sets with a nice shine.

Choosing Your Chocolate

Chocolate with 60-70% cacao gives the best balance. You can use regular grocery store brands, but trying better ones like Ghirardelli or Guittard really takes the cake up a notch. I figured this out during a chocolate tasting class that completely changed my baking.

Making It Ahead Of Time

This cake actually tastes better the next day as the flavors get stronger. You can wrap the unfrosted cake tight and freeze it up to 3 months. For parties, I often bake the cake way before, freeze it, then thaw and frost it right before serving.

All About Cocoa Powder

Dutch-processed cocoa makes things darker with a smoother taste, while regular cocoa has more fruity notes. Both work great in this cake - I've tried lots of times with each type while coming up with this recipe. Regular cocoa works really well with the coffee in the mix.

Fixing Common Problems

Knowing some cake science helps avoid issues. If your cake sinks in the middle, check if your baking powder is fresh and your oven heat is right. If it's too dense, make sure your ingredients weren't cold and you didn't mix too much. I learned all this from teaching baking classes for years.

Frequently Asked Questions

→ Can I use chips instead of chocolate bars?
Bars melt better. Chips have stabilizers that can mess with the texture.
→ What’s the point of adding coffee?
Coffee boosts the chocolate flavor but won’t make it taste like coffee. You can use hot water instead.
→ How far in advance can I bake this?
It’ll stay fresh for 3 days on the counter or 5 days in the fridge.
→ Why do you whip the ganache?
Whipping makes it lighter and fluffier, like mousse, and spreading gets way easier.
→ What if my ganache isn’t soft enough?
Zap it in the microwave for 15 seconds at a time, stirring in between, until it’s spreadable.

Difficulty: Intermediate

Cuisine: American

Yield: 12 Servings (1 large cake (9x13-inch))

Dietary: Vegetarian

Ingredients

→ Ganache Topping

01 1 cup (240ml) heavy cream
02 8 ounces (227g) finely chopped semi-sweet or dark chocolate (avoid using chips)

→ Cake Base

03 3/4 teaspoon baking powder
04 1 3/4 cups (210g) all-purpose flour
05 1 cup (227g) sour cream
06 3/4 cup (180ml) hot coffee or water
07 3/4 cup (63g) unsweetened cocoa powder
08 1 2/3 cups (356g) brown sugar
09 2 large eggs
10 1 1/2 teaspoons baking soda
11 1/2 cup (120ml) vegetable oil
12 1 teaspoon vanilla extract
13 1/2 teaspoon kosher salt
14 Nonstick spray for coating the pan

Instructions

Step 01

Warm the cream in the microwave until hot to the touch. Toss in the chopped chocolate, let it rest for 2 minutes, then stir until silky and fully mixed. Leave it to cool down.

Step 02

Turn the oven on to 350°F. Butter or spray a 9x13-inch baking dish to prevent sticking.

Step 03

Combine cocoa powder and hot water or coffee. Stir until smooth and thickened a bit.

Step 04

Blend together brown sugar, sour cream, oil, eggs, and vanilla. Gently fold in the flour, baking soda, baking powder, and salt until just mixed.

Step 05

Pour the mix into the greased dish. Bake for 30-35 minutes, or until a toothpick inserted comes out clean. Let it cool for about an hour.

Step 06

Once the ganache is at room temperature and thick like peanut butter, whip it for 4 minutes until pale and fluffy. Spread across the cooled cake.

Notes

  1. Use real chocolate for the ganache—skip the chips.
  2. Swap hot water for coffee if you want a richer, deeper taste.
  3. Store at room temp for 3 days or refrigerate for up to 5 days.
