Ingredients

Scale

Main Ingredients

  • 4 eggs (room temperature) – separated
  • ¾ cup sugar
  • ½ cup unsalted butter – melted and slightly cooled
  • 1 teaspoon vanilla extract
  • ¾ cup all-purpose flour
  • ¼ cup freshly squeezed lemon juice
  • Grated zest from 2 large lemons
  • 1 ¾ cups milk – lukewarm
  • Powdered sugar for dusting

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 325°F (163°C). Line an 8×8-inch baking dish with parchment paper, leaving an overhang on the sides for easy removal. Lightly grease the parchment with cooking spray to prevent sticking, then set aside.
  2. Whip Egg Whites: In a clean bowl, whip the egg whites until stiff peaks form. This will add lightness to the custard cake. Set aside carefully.
  3. Mix Egg Yolks and Sugar: In another bowl, beat the egg yolks together with the sugar until the mixture turns pale yellow and thickens slightly, creating a creamy base for the batter.
  4. Add Butter and Vanilla: Pour in the melted, slightly cooled butter and vanilla extract to the yolk mixture. Stir until everything is evenly combined for a rich, smooth flavor.
  5. Incorporate Flour: Gradually mix the all-purpose flour into the wet ingredients until fully incorporated, ensuring there are no dry patches.
  6. Add Lemon Elements: Stir in freshly squeezed lemon juice and lemon zest, giving the batter a fresh, citrusy brightness that defines this cake.
  7. Combine Milk: Slowly beat the lukewarm milk into the mixture to loosen the batter, making it very thin and smooth.
  8. Add Egg Whites: Gently whisk in the stiff egg whites by hand. Do not overmix; leave some small lumps of egg whites visible. These lumps will float to the surface during baking and create the signature top layer of the custard cake.
  9. Bake the Cake: Pour the thin batter into the prepared pan. Bake for 40-60 minutes, checking at around 35 minutes. The cake is done when it’s barely jiggly in the center but the top feels firm to the touch. If the top browns too quickly, cover the cake loosely with aluminum foil to prevent burning. Avoid overbaking or the cake will become rubbery instead of custardy.
  10. Cool and Serve: Allow the cake to cool completely in the pan. Once cooled, dust generously with powdered sugar. Slice and serve chilled or at room temperature. Store any leftovers in the refrigerator.

Notes

  • The batter is very thin, so don’t be alarmed; this is normal and key to the cake’s custard-like texture.
  • Check the cake early to prevent overbaking, which leads to a rubbery texture instead of the desired creamy custard consistency.
  • Using room temperature eggs helps achieve better volume when whipping the egg whites.
  • Covering the cake with foil during baking helps prevent premature browning on top.
  • Leftover cake should be stored in the fridge and consumed within 3 days for best quality.
