Step‑by‑Step Instructions for Lemon Custard Cake
Step 1: Preheat and Prepare
Begin by preheating your oven to 325°F (160°C). While the oven warms up, take an 8×8-inch baking pan and line it with parchment paper, then lightly grease the paper to ensure easy removal after baking. This step is crucial for achieving a beautiful Lemon Custard Cake that releases seamlessly.
Step 2: Whisk Egg Yolks and Sugar
In a mixing bowl, combine the room temperature egg yolks and granulated sugar. Using a whisk, beat the mixture until it turns pale and thick—about 3 to 5 minutes. Next, incorporate the melted butter, fresh lemon zest, lemon juice, and vanilla extract, mixing well until all ingredients are fully combined, creating a luscious base for your cake.
Step 3: Add Dry Ingredients
Gradually whisk in the all-purpose flour and a pinch of salt to the egg yolk mixture. Ensure you mix thoroughly until there are no lumps. Then, slowly add the warm milk, stirring gently to create a smooth, thin batter. This magic layer will guide your Lemon Custard Cake’s unique texture, so take your time with this step.
Step 4: Beat Egg Whites
In a separate bowl, beat the egg whites with an electric mixer until stiff peaks form; this usually takes about 3 to 5 minutes. The egg whites will become glossy and hold their shape. Gently fold one-third of the beaten egg whites into the batter to lighten it, and then carefully incorporate the remaining egg whites, ensuring the mix stays airy.
Step 5: Bake the Cake
Pour the batter into your prepared baking pan, spreading it evenly. Slide the pan into the preheated oven and bake for 40 to 45 minutes. The top should turn a lovely golden color and spring back when lightly touched. This visual cue indicates that your Lemon Custard Cake is perfectly baked and ready for cooling.
Step 6: Cool and Chill
Once baked, remove the cake from the oven and let it cool in the pan completely. This may take about an hour. After cooling, it’s essential to refrigerate the cake for at least one hour to allow the custard layer to set properly. This step ensures that your cake slices beautifully when served.
Step 7: Serve and Enjoy
After chilling, carefully cut the Lemon Custard Cake into squares. For an elegant touch, dust each square lightly with powdered sugar just before serving. This added sweetness contrasts beautifully with the zesty lemon flavors, making your delightful cake the perfect treat for any occasion!
