Coffee and Cream Layer Cake

👨‍🍳 Method

For the Sponge Cake

1. 1
   Preheat the oven to 180°C (355°F).

   ⚙ Preheating the OvenOven

   💡Put things in the oven only once it's reached temperature, after the heating light has gone off: an oven that hasn't reached temperature changes baking times, and the bake burns outside or stays underbaked.
2. 2
   Whip the eggs and sugar 5 minutes, until the mixture is pale, thick and very fluffy.

   💡Room-temperature eggs whip better than cold eggs. Take them out of the fridge 30 minutes before baking. Warm eggs also make a more stable foam that holds up in the oven.
3. 3
   Add and mix on low speed, just until they are absorbed.
4. 4
   Sift the flour, cocoa and baking powder over the top and Fold gently, just until the flour is absorbed.

   💡Fold with a spatula, in broad strokes from the bottom up, and stop when there are no streaks: vigorous mixing knocks the air out of the foam. Add whipped mixtures in stages: a quarter first, to lighten the mixture.

   💡Fold with a spatula, in broad strokes from the bottom up, and stop when there's no dry flour: vigorous mixing of a batter with flour develops gluten.

   💡Check by the cue (until…), not just the clock: every oven bakes a little differently.
7. 7
   Let the cake cool completely.

For the Cream Filling

1. 8
   Whip the cold cream on medium speed, until it starts to thicken.

   💡Cold cream whips quickly and holds firm: warm cream won't hold air. Stop when the peaks are firm, before it turns grainy.

   💡Whip cream very cold, in a chilled bowl with chilled beaters, and stop when it holds firm: overwhipping turns it grainy and buttery.
2. 9
   Add the powdered sugar and keep whipping on high speed to firm peaks.

2. 11
   Cut the cooled cake horizontally into 2 layers.

   Knife

   💡Only cut a completely cooled cake into layers: a warm cake crumbles under the knife and the cream melts on it.
3. 12
   Spread cream between the layers.

4. 13
   Cover the cake with the rest of the cream.

   💡A thin coat of cream over the whole cake before the final coating catches the crumbs, so the coating comes out smooth.
5. 14
   Sprinkle the cocoa and grated chocolate on top.
6. 15
   Chill 2 hours before serving.
