How to Make The Best Lemon Custard Cake
Step 1: Preheat the Oven
Preheat your oven to 325°F (163°C). Grease an 8-inch square baking dish and line it with parchment paper for easy removal after baking.
Step 2: Prepare the Batter
In a large bowl, beat the egg yolks with the granulated sugar until pale and creamy. Mix in the melted butter, grated lemon zest, and freshly squeezed lemon juice until well combined.
Step 3: Combine Dry Ingredients
Sift in the all-purpose flour and salt. Mix gently until just combined. Gradually whisk in the whole milk until you achieve a smooth batter.
Step 4: Whip Egg Whites
In a separate clean bowl, beat the egg whites until stiff peaks form. This step is essential for adding airiness to your cake. Gently fold the whipped egg whites into your lemon batter in three additions. Be careful not to deflate them!
Step 5: Bake the Cake
Pour the batter into your prepared baking dish. Bake for 40-45 minutes or until the top turns golden brown and the center is just set. Allow it to cool completely in the pan before serving.
Step 6: Serve Your Creation

- Skipping the cooling step: Cutting into the cake while it’s still warm can result in a messy presentation. Allow it to cool completely in the pan before slicing.
- Not using fresh lemon juice: Bottled lemon juice lacks the vibrant flavor that fresh lemons provide. Always opt for freshly squeezed lemon juice for maximum flavor.
