Ingredients

Scale

Eggs & Dairy

  • 4 large eggs, separated and at room temperature
  • 1 ½ cups whole milk, lukewarm
  • ½ cup heavy cream, lukewarm
  • ½ cup salted butter, melted and cooled

Dry Ingredients

  • 1 cup baker’s sugar (superfine sugar)
  • 1 cup all-purpose flour

Flavorings

  • 2 teaspoons vanilla extract

Instructions

  1. Prepare Baking Pan: Preheat your oven to 325°F (163°C). Butter an 8”x8” square baking pan thoroughly to prevent sticking.
  2. Beat Egg Yolks and Sugar: In a mixing bowl, beat the egg yolks and baker’s sugar together until the mixture turns pale yellow and creamy, which should take about 1 to 2 minutes.
  3. Add Butter and Vanilla: Pour in the melted and cooled salted butter along with the vanilla extract. Beat everything together until fully combined.
  4. Incorporate Flour: Gradually beat in the all-purpose flour until it is fully mixed into the batter.
  5. Add Milk and Cream: Combine the lukewarm whole milk and heavy cream, then slowly pour the mixture into the batter while mixing steadily to create a smooth consistency.
  6. Whip Egg Whites: Using a standing mixer fitted with the whisk attachment, beat the egg whites until stiff peaks form, creating a fluffy and airy texture.
  7. Fold Egg Whites into Batter: With a large whisk, gently fold the whipped egg whites into the batter in 2 to 3 additions, mixing lightly to preserve their airy texture. The batter will appear as two layers, with the egg whites floating on top.
  8. Pour into Pan: Carefully pour the combined batter into the prepared baking pan, spreading it evenly.
  9. Bake the Cake: Place the pan in the preheated oven and bake for 40 to 45 minutes. The cake is done when the center is still slightly jiggly but the batter no longer sloshes. The top will have a light golden brown color.
  10. Cool the Cake: Remove the cake from the oven and allow it to cool completely at room temperature.
  11. Set and Serve: Let the cake sit for 2 to 3 hours to set fully. Before serving, dust the top with powdered sugar and cut into 9 pieces, removing each slice carefully from the pan one at a time to maintain the custard layer.

Notes

  • Make sure the eggs are at room temperature to achieve the best texture in the batter.
  • Be gentle when folding the egg whites to preserve their fluffiness; overmixing will deflate the batter.
  • The center of the cake should still jiggle slightly when done baking; this helps maintain the custard layer.
  • Allowing the cake to sit for a few hours enhances the custard’s texture and flavor before slicing.
  • Use superfine (baker’s) sugar for smoother mixing and better texture.
