Sponge Cream Cake

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the sponge

  1. Preheat the oven to 350°F (175°C).

  2. Beat the eggs until very light.

  3. Add the sugar and a pinch of salt, then mix in the water.

  4. Gradually fold in the sifted flour and baking powder.

  5. Divide the batter into two layers and bake until golden.

Make the cream

  1. Heat the milk, then thicken the milk and sweeten it to taste.

  2. Stir in the egg yolk just before removing from heat.

Assemble and finish

  1. Fill the layers with the cream.

  2. Frost the top with the beaten egg whites.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Whipped to trap air, giving the sponge its light structure.
All-purpose flour
Provides the starch and gluten that set the sponge's structure as it bakes.
Granulated sugar
Sweetens the sponge and helps it hold air when beaten with the eggs.
Baking powder
Releases gas during baking so the batter rises.
Milk
Forms the base of the cream filling, providing moisture and richness.
Egg yolk
Thickens the cream filling as it heats, giving it a set, custard-like texture.

The step that matters

Stir in the egg yolk just before removing from heat. Egg yolk proteins thicken when heated but scramble if overheated, leaving the cream grainy or lumpy. Adding it near the end and removing from heat promptly keeps it smooth.
