Genoise gets its lift from whole eggs whipped with sugar. It is slightly drier than a butter cake, which makes it excellent for layered desserts and flavoured syrups.

What you need

Ingredients

Metric US Ingredient
4 large 4 large eggs
120 g ½ cup granulated sugar
120 g 1 cup plain flour Sifted.
57 g ¼ cup unsalted butter Melted and cooled.
5 ml 1 tsp vanilla extract Optional.

How to make it

Method

  1. Heat the oven to 177°C / 157°C fan / 350°F. Line the base of a 20 cm / 8-inch round tin and lightly grease the sides.
  2. Put the eggs and 120 g sugar in a heatproof bowl over barely simmering water. Whisk until warm and the sugar has dissolved.
  3. Remove from the heat and beat with an electric mixer for about 8 to 10 minutes until tripled in volume and at ribbon stage.
  4. Fold in the sifted 120 g flour in three additions.
  5. Mix a spoonful of batter into the melted butter, then fold that mixture gently back into the main batter with the vanilla.
  6. Pour into the tin and bake for 25 to 30 minutes until springy and a skewer comes out clean.
  7. Cool in the tin for 10 minutes, then turn onto a wire rack and cool completely.
