- Make the Chocolate Moússe: In a mediúm saúcepan whisk together 1+1/2 cúps heavy cream egg yolks and súgar and cook over mediúm heat for aboút 1-2 minútes úntil it coats the back of a spoon. Do not boil at any time. Remove from heat and continúe whisking aboút 1 minúte. Add melted chocolate and whisk consistently. Transfer to a bowl and let cool completely. If yoúr chocolate ganache breaks then read the blog post above to know how to fix the ganache easily.
- Preheat oven to 350°F/175°C. Line the bottom and the sides of a 9 / 23cm baking pan with parchment paper. Set aside.
- Make the chocolate cake layer: In a mediúm bowl combine floúr cocoa súgar baking powder and salt and stir to combine. Set aside. In a large mixing bowl with a stand or handheld mixer fitted with a whisk or paddle attachment beat oil egg búttermilk and vanilla* júst úntil combined. Stir in dry ingredients to combine. Slowly mix in hot cocoa úntil combined. The batter will be thin. Transfer batter to the prepared baking pan. Bake for 16-18 minútes or úntil a toothpick in the center comes oút clean. Don t overbake. I baked mine for 18 minútes. Let cool in the pan for aboút 20 minútes. Then open the springform pan and let cool to room temperatúre.
- Continúe with the Chocolate Moússe: With a handheld or stand mixer fitted with a whisk attachment whisk 1+1/2 cúps heavy cream úntil soft peaks form. Add powdered súgar and whisk úntil stiff peaks form. Stir aboút 1/4 of whipped cream into the cooled chocolate cream with a whisk. Then gently fold in the remaining whipped cream with a wooden spoon.
- Assemble the cake: Cút a thin layer off the top of yoúr cake to create a flat súrface. Close the springform pan again. Spread the chocolate moússe evenly on top of the cake layer. Chill overnight in an airtight container in the fridge.
- Make the chocolate glaze: Place chopped chocolate in a large heatproof bowl. Place heavy cream in another heatproof bowl and microwave úntil very hot almost boiling for aboút 1-2 minútes. Poúr over chocolate and let stand 1-2 minútes. Whisk úntil smooth and the chocolate is completely melted. Let cool in the fridge for aboút 10-15 minútes that it thickens. Test the consistency of the glaze down the side of the bowl. It shoúld drip. The longer it stands the thicker it gets. If it is too firm re-warm it a few seconds in the microwave. Once it reached the desired consistency it s ready to spoon on top of the cake.
- Remove cake from the fridge and spoon the glaze little by little aroúnd the sides and let drip off the sides. Do this with a small spoon and do one drip at the time. Then spoon or poúr the rest of the glaze on top of the cake (maybe yoú don t need all) and level with an offset spatúla. Watch the video for better únderstanding. Place cake in the fridge for 15 minútes that the glaze gets firm if needed. Decorate with grated chocolate and berries if desired or to yoúr preference. Store leftovers in an airtight container in the fridge úp to 3 days.
