Ingredients Equipment Method Notes

Ingredients
  

  • 4 large eggs, separated at room temperature
  • 1 1/2 cups granulated sugar
  • 1/2 cup unsalted butter, melted
  • 1 cup all-purpose flour
  • 2 cups whole milk, lukewarm
  • 1/2 cup fresh lemon juice from about 2-3 lemons
  • 1 tablespoon lemon zest
  • 1/4 teaspoon salt

Equipment

  • 1 8x8 inch baking pan
  • 2 Mixing Bowls
  • 1 Electric Mixer

Method
 

  1. Preheat your oven to 325°F (160°C). Grease and flour an 8x8 inch baking pan.
  2. In a large bowl, whisk the egg yolks with the granulated sugar until the mixture becomes pale and creamy.
  3. Whisk in the melted butter, lemon zest, and lemon juice until fully combined.
  4. Gradually whisk in the flour and salt, alternating with the lukewarm milk. Mix until the batter is smooth and very thin.
  5. In a separate, clean bowl, use an electric mixer to beat the egg whites until stiff peaks form.
  6. Gently fold about one-third of the whipped egg whites into the batter to lighten it. Then, carefully fold in the remaining egg whites until just combined.
  7. Pour the batter into the prepared pan. Bake for 40-50 minutes, or until the top is golden brown and the center is set but still has a slight wobble.
  8. Let the cake cool completely in the pan before slicing. Dust with powdered sugar before serving.

Notes

Ensure all ingredients are at their specified temperatures (room temp eggs, lukewarm milk) for the best results.
Do not overmix when folding in the egg whites; this is key to creating the separate layers.
Let the cake cool completely before slicing to allow the custard to set properly.
