This Magic Lemon Custard Cake is a delicate, luscious dessert that magically splits into three distinct layers during baking: a spongy cake layer, a creamy custard base, and a tangy lemon curd layer. Infused with fresh lemon juice and zest, it’s a perfect balance of sweet and tart, offering a light yet indulgent finish to any meal.

Ingredients

Scale

Wet Ingredients

  • 4 large eggs, room temperature
  • 1/2 cup unsalted butter, melted and cooled (1 stick)
  • 1 teaspoon vanilla paste or extract
  • 1/4 cup lemon juice (from about 2 large lemons)
  • 1 3/4 cups whole milk, room temperature

Dry Ingredients

  • 3/4 cup sugar
  • 1/2 teaspoon kosher salt
  • 3/4 cup all-purpose flour, sifted
  • 1/4 teaspoon cream of tartar (optional)

Flavorings and Garnishes

  • 2 tablespoons finely grated lemon zest (from about 2 large lemons)
  • Powdered sugar for dusting (optional)

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 325°F (163°C) and line an 8×8-inch baking pan with parchment paper to prevent sticking and ensure easy removal.
  2. Whisk Eggs and Cream of Tartar: Using a stand mixer or handheld beater, whisk the eggs and cream of tartar (if using) on high speed until the mixture becomes frothy and light in color, which helps to incorporate air and give the cake its light texture.
  3. Add Sugar and Salt: Gradually add sugar and kosher salt to the egg mixture while continuing to whisk. Continue until the mixture thickens and turns pale, ensuring the sugar begins to dissolve and the batter gets volume.
  4. Incorporate Butter and Vanilla: Slowly add the melted, cooled butter and vanilla paste or extract to the batter, mixing just until combined to maintain the airiness of the mixture.
  5. Fold in Flour: Sift the flour over the batter and gently fold it in to avoid deflating the air bubbles, which are essential for the cake’s magical texture.
  6. Add Lemon Juice and Zest: Mix in the freshly squeezed lemon juice and finely grated lemon zest gently to infuse bright citrus flavor evenly throughout the batter.
  7. Pour in Milk and Fold Smoothly: Slowly pour the whole milk into the batter, folding gently until the mixture is smooth and uniform, ensuring even distribution of ingredients.
  8. Bake the Custard Cake: Pour the batter into your prepared pan and bake for 45 to 55 minutes or until the top is lightly golden and the center is just set but still jiggles slightly when moved, an indication of its custard nature.
  9. Cool and Chill: Let the cake cool completely at room temperature. Cover and refrigerate for at least 1 hour or overnight; chilling helps the layers settle and the custard firm up beautifully.
  10. Serve: Cut into squares and dust with powdered sugar before serving. Optionally, garnish with thin lemon slices for an elegant presentation and enhanced lemon aroma.

Notes

  • Using room temperature eggs and milk helps create a smoother batter with better volume.
  • Cream of tartar is optional but helps stabilize egg whites for increased fluffiness.
  • Be gentle when folding flour and milk to maintain the air incorporated into the eggs, which is crucial for the distinct layers.
  • Allowing the cake to cool completely and then refrigerating it for at least an hour ensures the custard layer sets properly.
  • Use fresh lemons for the best flavor impact in juice and zest.
  • This cake’s beauty lies in its magical transformation—the final layered texture makes it a conversation starter and delightful treat.
