Instructions
- Preheat the oven to 350°F (175°C) and grease the inside of a 9-inch springform pan.
- Prepare the pan: Remove the ring, lay a sheet of parchment paper on the bottom plate, and close the ring on top. Some paper will be sticking out of the sides.
- Mix dry ingredients: In a medium bowl, whisk together the flour, cornstarch, cocoa powder, baking soda, baking powder, and salt. Set aside.
- Combine wet ingredients: In a large mixing bowl, whisk together the fine granulated sugar, dark brown sugar, and oil until it resembles wet sand. Then whisk in the eggs and vanilla, followed by the sour cream.
- Combine mixtures: Dump in the dry ingredients and mix until it’s halfway combined. Pour in the hot coffee and mix until smooth. The batter will be very thin.
- Bake the cake: Pour the batter into the prepared pan and bake for 25-30 minutes or until a toothpick comes out clean with a few moist crumbs.
- Cool the cake: Allow the cake to cool completely at room temperature or in the refrigerator. Once cooled, remove the ring from the pan and level off the top.
- Prepare cake soak: Stir together the hot coffee and cocoa powder, then spoon the mixture over the cake, soaking the entire surface.
- Make the mousse: Add the chopped chocolate to a heat-safe bowl. Use a saucepan with about 1/2 inch of water and place over medium heat. Place the bowl on top and stir until smooth, then remove from heat.
- Whisk in egg yolks: After cooling slightly, whisk in the egg yolks one at a time until thickened.
- Bloom gelatin: Sprinkle gelatin over 3 tablespoons of water and let sit. Heat 3/4 cup of heavy cream in the cleaned saucepan until steaming. Whisk in the bloomed gelatin until melted.
- Combine mixtures: Pour half of the cream into the chocolate mixture, whisk until smooth, then add the rest of the hot cream.
- Whip cream: In a large bowl, whip 1 cup of heavy cream until light and fluffy with stiff peaks.
- Whip egg whites: In a clean bowl, whip egg whites with cream of tartar until foamy. Gradually add sugar and whip until soft peaks form.
- Fold mixtures: Gently fold the whipped cream into the chocolate mixture, followed by the meringue until fully incorporated.
- Pour mousse: Pour the mousse over the chocolate cake and chill in the refrigerator for at least 4 hours, preferably overnight.
- Make ganache: When the mousse has set, release the ring from the pan and peel back the cake collar. Heat heavy cream until hot and bubbling, then pour over chopped chocolate and whisk until combined.
- Finish the cake: Pour the ganache over the cake, spreading it out to allow it to drip down the sides. Chill for at least 30 minutes to set.
- Serve and enjoy! Slice and serve your delicious chocolate mousse cake!
