Ingredients
- 1 1/2 cups all-purpose flour
- 3/4 cup Dutch-processed cocoa powder
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1 cup granulated sugar
- 1/2 teaspoon salt
- 2 large eggs
- 1/2 cup vegetable oil
- 1/2 cup full-fat sour cream
- 1 teaspoon vanilla extract
- 1/2 cup hot water
- 11 ounces dark chocolate (55-60% cocoa), chopped and divided
- 2 cups heavy whipping cream (35% fat), divided
- 3 tablespoons honey or light corn syrup, divided
- 1 tablespoon cocoa powder
Instructions
- Preheat your oven to 350°F (175°C) and line the base of a 9-inch springform pan with parchment paper, greasing the sides with butter.
- Sift the flour, 3/4 cup cocoa powder, baking powder, and baking soda into a bowl; whisk in the sugar and salt until combined.
- In a separate bowl, whisk the eggs, oil, sour cream, and vanilla, then stir into the dry ingredients to form a thick paste.
- Pour in the hot water and whisk until the batter is thin and glossy, then pour into the prepared pan and bake for 20-25 minutes.
- Allow the cake to cool completely on a wire rack, then level the top with a serrated knife and place back into the springform pan lined with fresh parchment.
- Make the ganache base by pouring 1/2 cup of simmered cream and 1 tablespoon honey over 7 ounces of chopped chocolate; let sit for two minutes before whisking into a smooth emulsion.
- Whip 1 cup of cream with 1 tablespoon of cocoa powder to soft peaks, then gently fold into the cooled, room-temperature ganache in stages.
- Spoon the whipped truffle mixture over the leveled cake, smooth the top with an offset spatula, and refrigerate for at least two hours to set.
- Prepare the final glaze by melting 4 ounces of chocolate with the remaining cream and honey, then pour it over the chilled cake.
- Return the cake to the refrigerator for one final hour before slicing and serving.
Notes
To ensure a perfectly smooth finish, always use an offset spatula when spreading the truffle layer and the glaze. For the best flavor profile, select a high-quality dark chocolate with a cocoa percentage between 55% and 60%, as higher concentrations may lead to a grainy texture during the emulsion process.
