I think one of the first things I baked at home once I decided to attend culinary school and become a “serious” baker was a cake just like this, a rich chocolate cake with a homemade chocolate pudding and fresh crumbs. It wasn’t a huge challenge, but there was just something about being able to make one of my favorite bakery treats at home all by myself.

It was definitely a proud moment, and one that made me think “okay, I can do this.” And you know what, you can do it too!

Step-by-Step Instructions

1. Prepare the Cake Batter

Start by preheating the oven to 350°F (175°C) and greasing two round cake pans. In a large bowl, mix the flour, cocoa powder, sugar, baking powder, baking soda, and salt until everything looks evenly combined.

2. Add the Wet Ingredients

Crack the eggs into the bowl and add the milk, oil, and vanilla extract. Stir gently until a smooth batter forms. Slowly pour in the hot coffee or water while mixing. The batter will look thin, yet that moisture helps create a soft cake.

3. Bake the Cake Layers

Divide the batter evenly between the prepared pans. Bake for about 30 to 35 minutes until a toothpick inserted in the center comes out clean. Let the cakes cool completely before assembling.

4. Make the Chocolate Pudding

In a saucepan, whisk together the milk, sugar, cornstarch, and salt. Cook over medium heat while stirring constantly until the mixture thickens into a pudding consistency. Remove from heat and stir in the chopped chocolate, butter, and vanilla until smooth.

5. Cool the Filling

Transfer the pudding into a bowl and let it cool until it becomes thick but spreadable. Stir occasionally so a skin does not form on top.

6. Trim the Cake Layers

Once the cakes are cool, trim the tops slightly to create flat surfaces. Save the trimmed cake pieces and crumble them into fine crumbs. These crumbs will become the cake’s outer coating.

7. Assemble the Cake

Place one cake layer on a serving plate and spread a generous layer of chocolate pudding on top. Add the second cake layer and spread more pudding over the top and sides to act as a light frosting.

8. Coat with Cake Crumbs

Press the chocolate cake crumbs gently around the sides and top of the cake until it is fully covered. The crumbs create the signature dark appearance that makes this cake so unique.

Serving Suggestions

Brooklyn Blackout Cake tastes wonderful when served slightly chilled or at room temperature. Each slice reveals rich chocolate layers with creamy pudding filling that feels smooth and indulgent.

A scoop of vanilla ice cream on the side adds a cool contrast to the deep chocolate flavor. The creamy ice cream melts slowly and complements the cake beautifully.

For a slightly elegant presentation, dust a little cocoa powder or add a few chocolate curls on top before serving. The extra garnish gives the cake a refined bakery-style finish.

During celebrations, slicing the cake into generous wedges works well since the cake itself feels rich and satisfying.

Tips & Variations

Coffee deepens the chocolate flavor without making the cake taste like coffee.

Warm cake layers can melt the pudding filling and make assembly messy.

Baking a small extra cupcake can provide more crumbs for coating if needed.

Dark chocolate in the pudding creates a richer and slightly less sweet filling.

A few chocolate chips in the batter create small pockets of melted chocolate.
