Instructions
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
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
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
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
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
Prepare Pudding Thickener
In a saucepan whisk together Dutch‑process cocoa powder and cornstarch until combined.
Time: PT2M
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
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
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
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
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
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
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
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
