Use the whisk attachment to whisk the eggs and sugar for a few minutes until the mixture is creamy and light.
3 Eggs, 1½ cups Sugar
Add the oil and applesauce and mix well.
½ cup oil, ½ cup Applesauce
Next, add the sour cream and vanilla extract and mix well.
½ cup Sour cream, 1 tablespoon Vanilla extract
Add in the dry ingredients and gently mix. Do not overmix.
Pour the batter into the prepared pans and bake for 30-35 minutes. Let cool down in the pan for 10 minutes, then transfer to a cooling rack to cool down completely.
How To Make The Cream
Pour the water and sugar into a saucepan and bring to a boil. Bring the heat down and let simmer for a few minutes.
¾ cup Sugar, ¼ cup Water
Whisk the egg yolks and vanilla extract for 5 minutes until they are pale, light and creamy.
6 Yolks, 1 tablespoon Vanilla extract
While the yolks are whisking, stream the hot syrup on the side of the bowl and keep whisking until the bowl cools down. This may take up to 7-10 minutes.
In a separate bowl, soften the Mascarpone cheese until it is lump-free and smooth. Add the cheese to the yolk mixture and mix well.
500 grams Mascarpone cheese
How To Assemble
Place the first cake layer on the base turntable, brush it with the brewed coffee, and ensure it is not hot. Cover the cake with a generous amount of cream, then sift a good amount of cocoa powder over the cream.
½ cup Brewed Coffee, ½ cup Cocoa powder
Repeat these steps until you place the third cake layer. Cover the entire cake with mascarpone cream, and top the cake with a generous amount of dusting cocoa powder.
If you have leftover cream, pipe it on the cake and finish with more cocoa powder. Leave the cake in the fridge for 2-3 hours before serving.
