Ingredients
  

  • 3/4 cup granulated sugar
  • 1/2 cup unsalted butter softened
  • 3 large eggs separated
  • 1 tbsp lemon zest from about 2 lemons
  • 1/4 cup fresh lemon juice from about 2 lemons
  • 1/2 tsp vanilla extract
  • 1/3 cup all-purpose flour
  • 1 cup whole milk
  • 1/4 tsp salt
  • Powdered sugar for dusting, optional

Instructions
 

Prepare Your Baking Dish:

  • Preheat oven to 325°F (163°C).
  • Grease a 9-inch baking dish with butter or non-stick spray.

Mix the Wet Ingredients:

  • In a large bowl, cream together butter and sugar until light and fluffy.
  • Add egg yolks, lemon zest, lemon juice, and vanilla extract, mixing well.

Add the Dry Ingredients:

  • Gradually add flour and mix until just combined.
  • Slowly whisk in milk until the batter is smooth.

Beat the Egg Whites:

  • In a separate clean bowl, beat egg whites and salt until stiff peaks form.
  • Gently fold the egg whites into the batter without deflating them.

Bake:

  • Pour batter into the prepared baking dish.
  • Place the dish in a larger pan filled with hot water (halfway up the sides) to create a water bath.
  • Bake for 40–45 minutes, until the top is lightly golden and the custard layer is set.

Cool & Serve:

  • Let the cake cool for 15 minutes.
  • Dust with powdered sugar before serving warm or chilled.
