Ingredients

  • 2 1/2 cups All-Purpose Flour (sifted)
  • 3/4 cup Dutch-Process Cocoa Powder (plus extra 2 tbsp for pan dusting)
  • 1 teaspoon Baking Powder
  • 1/2 teaspoon Baking Soda
  • 1/2 teaspoon Kosher Salt
  • 1 Large Egg
  • 1 Egg Yolk (extra yolk for richness)
  • 1 teaspoon Vanilla Extract (pure)
  • 5 tablespoons Vegetable Oil
  • 1 1/2 cups Dark Brown Sugar (packed, soft like wet sand)
  • 1/2 cup Hot Water (helps cocoa bloom)
  • 1/4 cup Cocoa Powder (for pudding thickening)
  • 3 tablespoons Cornstarch
  • 2 cups Heavy Cream (1 cup for pudding, 1 cup for frosting)
  • 1 cup Whole Milk
  • 4 Egg Yolks (for pudding richness)
  • 4 ounces Milk Chocolate (chopped)
  • 2 tablespoons Golden Syrup
  • 6 ounces Dark Chocolate (chopped)
  • 1/2 cup Sour Cream
  • 4 tablespoons Unsalted Butter (cut into cubes)
  • 2 rounds Parchment Paper (cut to fit 8-inch pans)

Instructions

  1. Prepare Cake Pans

    Butter two 8‑inch cake pans, line with parchment rounds, then dust lightly with cocoa powder using a pastry brush.

    Time: PT5M

  2. Sift Dry Ingredients

    In a large bowl sift together the all‑purpose flour, Dutch‑process cocoa powder, baking powder, baking soda, and kosher salt.

    Time: PT5M

  3. Mix Wet Ingredients

    In another bowl whisk the whole egg, extra yolk, vanilla extract, vegetable oil, and dark brown sugar until smooth and no sugar lumps remain.

    Time: PT5M

  4. Combine and Bloom Cocoa

    Add the wet mixture to the dry ingredients, then slowly whisk in hot water until the batter is glossy and the cocoa is fully bloomed.

    Time: PT5M

  5. Bake Cake Layers

    Divide the batter evenly between the two prepared pans. Bake at 350°F for 30 minutes, or until a toothpick comes out clean.

    Time: PT30M

    Temperature: 350°F

  6. Prepare Pudding Thickener

    In a saucepan whisk together Dutch‑process cocoa powder and cornstarch until combined.

    Time: PT2M

  7. Make Chocolate Pudding

    Add heavy cream, whole milk, 4 egg yolks, dark brown sugar, and a pinch of salt to the cocoa‑cornstarch mixture. Cook over medium‑high heat, stirring constantly, until it reaches a boil, then reduce to low and whisk for 2 minutes until smooth. Strain through a fine mesh sieve into a bowl.

    Time: PT10M

  8. Chill Pudding

    Cover the pudding with plastic wrap pressed directly onto the surface to prevent a skin. Refrigerate for 4 hours until very cold.

    Time: PT4H

  9. Make Ganache Frosting

    In a saucepan bring heavy cream, a pinch of salt, and golden syrup to a boil. Remove from heat and whisk in dark chocolate, sour cream, and butter until fully melted and glossy.

    Time: PT5M

  10. Cool Frosting

    Transfer the ganache to a bowl, let it sit at room temperature for 1.5 hours, stirring every 30 minutes until it thickens to a spreadable consistency.

    Time: PT1H30M

  11. Level and Crumble Cake Layers

    Trim the tops of the baked cakes to make them flat. Reserve one layer for crumb coating; crumble it finely by hand or with a grater.

    Time: PT10M

  12. Assemble Cake with Pudding

    Place the first cake layer on a board, spread half of the chilled pudding evenly, then top with the second layer (pudding side down). Chill the assembled stack for 1 hour to set the filling.

    Time: PT15M

  13. Apply Ganache Frosting

    Using an offset spatula, coat the top and sides of the chilled cake with a thin crumb coat of frosting, then roll the cake in the reserved chocolate crumbs. Finish with a smooth final layer of ganache.

    Time: PT20M

  14. Final Chill and Serve

    Refrigerate the finished cake for 30 minutes to set the frosting, then remove parchment, slice with a hot, sharp knife, and serve.

    Time: PT30M

Critical Success Points

  • Blooming the cocoa with hot water for a glossy batter
  • Straining the chocolate pudding to ensure a smooth texture
  • Covering the pudding with plastic to prevent skin formation
  • Chilling the assembled cake before applying the ganache
  • Using a crumb coat to hide imperfections before the final frosting

Safety Warnings

  • Hot pudding can scorch and cause burns; stir constantly and keep an eye on the pan.
  • The ganache frosting is very hot when first made; handle with care.
  • Use a hot, dry knife for clean cake slices to avoid tearing.

cultural
Q

What are the most common mistakes to avoid when making Blackout Cake at home?

Yes. Bake and cool the cake layers up to two days ahead, store them wrapped at room temperature. The pudding can be made a day ahead and kept refrigerated. Assemble the cake no more than a few hours before serving, then keep the finished cake refrigerated.
