Preparation Phase & Tools to Use
Before diving into this delicious Lemon Custard Cake recipe, ensure that your kitchen is prepped for baking success. Start by gathering all your ingredients: eggs, granulated sugar, lemon zest, melted butter, fresh lemon juice, vanilla extract, all-purpose flour, salt, and milk. For tools, you will need a 9×9-inch baking pan, mixing bowls, a whisk, a spatula for folding, and a sifter for the flour and salt.
Preheat your oven to 325°F (160°C) prior to preparing the batter. This allows the oven to reach the perfect temperature for baking once your cake is ready. Greasing the baking pan and lining it with parchment paper is also essential to prevent the cake from sticking, making it easier to serve later. Ensure your mixing bowls and utensils are clean, especially if you’re whipping egg whites, as any grease can hinder the formation of stiff peaks. Following these steps will ensure a smooth cooking process and a beautiful cake.

Ingredients
- 4 large eggs, separated
- 1 1/4 cups granulated sugar
- 1 tablespoon lemon zest (freshly grated)
- 1/2 cup melted unsalted butter
- 1/2 cup fresh lemon juice
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1/4 teaspoon salt
- 1 1/4 cups milk (room temperature)
- Powdered sugar (for garnish, optional)
Instructions
Step 1: Preheat and Prepare Your Pan
Begin by preheating your oven to 325°F (160°C). While the oven is heating, take your 9×9-inch baking pan and grease it thoroughly with butter or cooking spray. Once greased, line the bottom with parchment paper to ensure that your cake releases easily after baking. This simple step can save you from a sticky situation!
Step 2: Whip the Egg Yolks and Sugar
In a mixing bowl, combine the egg yolks and granulated sugar. Whisk these together until the mixture becomes pale and creamy – this will take about 2-3 minutes of vigorous mixing. The sugar dissolves while incorporating air into the yolks, creating a light base for the cake. After achieving the right consistency, add in the freshly grated lemon zest, freshly squeezed lemon juice, melted butter, and vanilla extract, mixing well after each addition to fully customize the flavors.
Step 3: Combine Dry Ingredients
In a separate bowl, sift together the all-purpose flour and salt. Gradually incorporate this dry mixture into the wet ingredients, stirring gently to avoid any lumps. The goal is to achieve a smooth batter, so take your time with this step! Continue stirring until there are no visible flour pockets left.
Step 4: Mix in the Milk
Next, slowly pour in the room-temperature milk. Stir well until the batter is smooth. You should notice that the batter is quite thin at this stage – that’s perfect, as the custard will form during the baking process.
Step 5: Beat the Egg Whites
In another clean mixing bowl, use a whisk or an electric mixer to beat the egg whites until stiff peaks form. This step is crucial, as it introduces air into the cake, allowing it to rise beautifully. Once the egg whites are whipped, carefully fold them into the batter in three separate batches, using a spatula. Be gentle, as you don’t want to deflate the airy structure of the beaten egg whites.
Step 6: Bake the Cake
Pour the completed batter into the prepared baking pan. Smooth the top with a spatula for an even bake. Place the pan in the preheated oven and bake for approximately 40-45 minutes. You’ll know your cake is ready when the top is golden brown and the center has a slight jiggle – this is okay as it will set while cooling.
Step 7: Cool and Serve
Once baked, remove the cake from the oven and allow it to cool completely in the pan. This cooling time helps firm up the custard layer. If you’d like, dust the cake with powdered sugar right before serving to add a sweet finishing touch. Cut into squares, serve, and delight in the praises from your guests!
