Step‑by‑Step Instructions for Lemon Custard Cake
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). While your oven heats up, grab a 9-inch round cake pan and generously grease it with butter or non-stick spray to ensure your Lemon Custard Cake releases easily once baked.
Step 2: Cream the Butter and Sugar
In a large mixing bowl, combine the softened unsalted butter and granulated sugar. Using an electric mixer, beat them together on medium speed for about 3-4 minutes until the mixture is light and fluffy. This step is essential for incorporating air into your batter for a light cake texture.
Step 3: Incorporate the Eggs
Next, add the three large eggs to the buttery sugar mixture one at a time. After adding each egg, mix on medium speed until fully incorporated—this should take about 30 seconds per egg—ensuring a smooth, homogenous batter.
Step 4: Combine Dry Ingredients
In a separate bowl, sift together the all-purpose flour, baking powder, and salt. This helps to eliminate lumps and evenly distribute the baking powder, crucial for the rise of your Lemon Custard Cake. Set this bowl aside while you prepare the wet ingredients.
Step 5: Mix Wet Ingredients
In another bowl, whisk together the whole milk, fresh lemon juice, lemon zest, and vanilla extract until well combined. This mixture will add a bright acidity and lovely aroma, setting the stage for the vibrant flavors of your cake.
Step 6: Combine Wet and Dry Ingredients
Now it’s time to bring everything together! Gradually add the dry ingredient mixture to the butter mixture, alternating with the wet mixture. Begin and end with the dry. Mix gently until just combined and the batter is smooth. Take care not to overmix, as this can lead to a dense cake.
Step 7: Bake the Cake
Pour the batter into your prepared cake pan and use a spatula to spread it evenly. Place the pan in the preheated oven and bake for 30-35 minutes. Keep an eye out for a golden top and perform the toothpick test—insert one into the center; it should come out clean.
Step 8: Cool the Cake
Once baked, remove the Lemon Custard Cake from the oven and allow it to cool in the pan for about 20 minutes. This cooling step helps the cake set before transferring it to a wire rack, where it should cool completely to prepare for layering.
Step 9: Layer with Custard
When the cake is completely cool, carefully slice it in half horizontally to create two layers. Generously spread the lemon custard between the layers and on top of the cake. This adds a delightful creamy contrast to the light sponge, enhancing the cake’s overall flavor.
Step 10: Garnish and Serve
Finally, dust the top of your beautiful Lemon Custard Cake with powdered sugar just before serving. This elegant touch adds visual appeal and a hint of sweetness, making your cake a stunning centerpiece for any gathering.

Make Ahead Options
These Lemon Custard Cake make ahead options are a busy cook's dream! You can prepare the cake itself up to 24 hours in advance—just bake and let it cool completely before wrapping it tightly in plastic wrap to keep it fresh. The lemon custard can also be made ahead and stored in the refrigerator for up to 3 days. To ensure the custard maintains its creamy texture, cover it with plastic wrap directly on the surface to prevent a skin from forming. When you’re ready to serve, simply slice the cake, layer it with the custard, and dust with powdered sugar for that final touch of elegance. Your homemade Lemon Custard Cake will be just as delicious, saving you precious time during busy weeknights!
Storage Tips for Lemon Custard Cake
Room Temperature: Store the Lemon Custard Cake at room temperature for up to 2 days, covering it with plastic wrap to keep it moist and fresh.
Fridge: If you have leftover cake, wrap it securely and store it in the refrigerator for up to 5 days. This helps maintain the custard's creamy texture.
Freezer: You can freeze the Lemon Custard Cake for up to 3 months. Wrap slices individually in plastic wrap, then place them in an airtight container or freezer bag.
Reheating: To enjoy, thaw in the fridge overnight and gently reheat in the microwave for about 15-20 seconds, just until warm. This will bring back the delightful flavors!
Helpful Tricks for Lemon Custard Cake
Proper Oven Temperature: Always preheat your oven fully to 350°F (175°C) before baking; an improperly heated oven can lead to uneven cooking.
Avoid Overmixing: Mix the batter until just combined. Overmixing can result in a dense Lemon Custard Cake instead of a light, airy texture.
Cooling the Cake: Allow the cake to cool completely before adding the custard; this helps to prevent the filling from melting into the cake layers.
Custard Consistency: If you're using homemade custard, ensure it has thickened adequately before layering; this will prevent it from seeping out.
Garnish Elegance: Dust the powdered sugar on the cake just before serving to keep it looking fresh and beautiful; early dusting can cause the sugar to dissolve.
