Sift the flour with the baking powder.
Fold the sifted flour mixture into the batter.
Gently fold in the beaten egg whites.
Divide the batter into two layers.
Bake
Bake at 350°F (175°C) until done.
Whip and assemble
Whip the heavy cream.
Sweeten the whipped cream to taste.
Flavor the whipped cream with coffee essence.
Spread the whipped cream between the layers.
Spread the whipped cream on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and colour, and help the batter bind and set when baked.
- Egg whites
- Trap air when beaten, giving the torte a light, airy structure.
- Sugar
- Sweetens the batter and helps the yolks cream into a smooth, thick mixture.
- All-purpose flour
- Provides the starch that sets during baking to give the layers their structure.
- Baking powder
- Releases gas in the batter, helping the layers rise in the oven.
- Heavy cream
- Whipped into a rich, stable topping and filling that adds moisture and fat.
The step that matters
Gently fold in the beaten egg whites.. Egg whites hold air that makes the layers light. Stirring vigorously or overmixing knocks out that air, so the torte bakes up dense and flat instead of airy.
