Step‑by‑Step Instructions for Lemon Custard Cake

Step 1: Preheat and Prepare
Begin by preheating your oven to 325°F (160°C). While it heats, prepare an 8×8-inch baking dish by lining it with parchment paper and greasing the sides. This will ensure your delightful Lemon Custard Cake releases easily after baking, giving you a beautiful finish.

Step 2: Whisk Egg Yolks and Sugar
In a large mixing bowl, whisk together the egg yolks and granulated sugar until the mixture becomes pale and thick, about 2-3 minutes. This step adds richness to the custard base. Next, pour in the melted butter, then add the lemon zest, lemon juice, and vanilla extract, mixing until well combined to create a fragrant batter.

Step 3: Incorporate Dry Ingredients
Gradually sift in the all-purpose flour and salt, stirring until just combined. This helps achieve the perfect texture for your cake. Now, slowly whisk in the warm milk until the batter is smooth and thin. Look for a consistency that’s almost pourable, as this will help with the layering of your Lemon Custard Cake.

Step 4: Beat Egg Whites
In a separate clean bowl, add the egg whites and beat them until they form stiff peaks. This should take about 2-3 minutes with an electric mixer. The whipped egg whites are crucial for incorporating air into your cake, giving it that light, airy texture.

Step 5: Fold Egg Whites into Batter
Carefully fold a third of the whipped egg whites into the lemon batter using a spatula, being gentle to retain air. Once incorporated, add the remaining egg whites in two batches, folding until just combined. You’ll have some small clumps, but be cautious not to overmix, as this preserves your cake’s fluffy texture.

Step 6: Bake the Cake
Pour the batter into your prepared baking dish and spread it evenly. Place it in the preheated oven and bake for 40-45 minutes, or until the top is golden and it springs back when touched gently. The edges should look slightly set while the center remains soft, indicating a perfect lemon custard layer for your cake.

Step 7: Cool and Refrigerate
Once baked, allow the Lemon Custard Cake to cool completely in the pan for about an hour. Then, refrigerate for at least 1 hour to let the custard set and flavors meld beautifully. This chill time is essential for that silky texture and makes serving so much easier.

Step 8: Serve and Enjoy
When ready to serve, cut the cake into squares and dust with powdered sugar for a lovely finish. You can enjoy this delightful Lemon Custard Cake chilled or at room temperature. Pair it with a dollop of whipped cream for an extra touch of indulgence and watch as it disappears from your spring gathering!

Expert Tips for Lemon Custard Cake

Room Temperature Eggs: Use eggs at room temperature to help achieve better volume and structure, ensuring a light and airy cake.
Warm Milk is Key: Make sure your milk is warm when added to the batter; this helps create a smooth, thin consistency necessary for layering.
Gentle Folding Technique: Be careful not to overmix the egg whites when folding; maintain the airy texture for a fluffy cake.
Cooling Time Matters: Allow the Lemon Custard Cake to cool completely in the pan before refrigerating; this helps set the custard layer properly.
Prep Ahead: Bake the cake a day in advance for a richer flavor and serve it chilled; it intensifies the delightful lemon taste you love!
