Ingredients

Egg Mixture

  • 4 eggs (separated)
  • 150 g sugar
  • 120 g butter (melted)
  • 1 tsp vanilla extract
  • Pinch of salt

Dry Ingredients

  • 120 g all-purpose flour

Wet Ingredients

  • 500 ml milk (lukewarm)
  • 80 ml fresh lemon juice
  • Zest of 2 lemons

Finishing

  • Powdered sugar (for dusting)

Instructions

  1. Prepare the Batter: Preheat the oven to 160°C and grease a baking dish. Beat the egg yolks with sugar until the mixture becomes pale and creamy. Add the melted butter, fresh lemon juice, lemon zest, and vanilla extract, mixing well to combine. Gradually stir in the all-purpose flour until the batter is smooth. Slowly incorporate the lukewarm milk while mixing; the resulting batter will be fairly thin.
  2. Whip the Egg Whites: In a clean, dry bowl, beat the egg whites with a pinch of salt until stiff peaks form. Gently fold the whipped egg whites into the batter in two to three additions, being careful to preserve their light and airy texture to achieve the signature layered consistency.
  3. Bake: Pour the combined batter into the prepared baking dish. Bake in the preheated oven for 45 to 55 minutes, or until the top is lightly golden but the center remains slightly jiggly, indicating a soft custard layer beneath the sponge.
  4. Cool & Serve: Allow the cake to cool completely at room temperature; it will set into two distinct layers during this time. Before serving, dust the top with powdered sugar to add an elegant finish.

Notes

  • Do not overmix the egg whites when folding to maintain the distinct layered texture.
  • Use freshly squeezed lemons for the best bright, citrus flavor.
  • Chilling the cake slightly before serving helps to further define the custard layer.
  • Ensure the baking dish is well greased to facilitate easy removal and prevent sticking.
