Step‑by‑Step Instructions for Lemon Custard Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C), allowing it to reach the perfect temperature for baking your Lemon Custard Cake. This step is essential for ensuring your cake rises beautifully and bakes evenly throughout. While the oven heats, gather your ingredients and equipment, including a mixing bowl and a whisk.
Step 2: Cream Butter and Sugar
In a large mixing bowl, combine ½ cup of softened unsalted butter and 1 cup of granulated sugar. Using an electric mixer or a whisk, cream the mixture together until it is light, fluffy, and pale in color, about 3-5 minutes. This step is crucial as it incorporates air into the batter, contributing to the cake's airy texture.
Step 3: Add Eggs
Next, crack 3 large eggs into the bowl one at a time, mixing thoroughly after each addition. Continue to blend until the mixture is smooth and well combined, which should take about 2-3 minutes. The eggs enhance the moistness of your Lemon Custard Cake and help bind the ingredients together.
Step 4: Incorporate Lemon Juice and Zest
Stir in 2 tablespoons of fresh lemon juice and 1 tablespoon of lemon zest to the mixture. Use a spatula or wooden spoon to fold these in gently until just combined. The lemon juice and zest will infuse your cake with a delightful zesty flavor, creating its signature tanginess.
Step 5: Mix Dry Ingredients
In a separate bowl, whisk together 1 ½ cups of all-purpose flour, 1 teaspoon of baking powder, and ¼ teaspoon of salt. This step ensures that the baking powder is evenly distributed and prevents any clumps, which will help your Lemon Custard Cake rise evenly during baking.
Step 6: Combine Wet and Dry Ingredients
Gradually add the flour mixture to the wet ingredients, alternating with ¾ cup of milk. Start with the flour, mix until just combined, then add the milk, blending gently until no dry streaks remain. Be careful not to overmix, as this can lead to a dense cake texture.
Step 7: Fold in Lemon Custard
Gently fold in ½ cup of lemon custard until it is evenly distributed throughout the batter. This step is key to achieving the cake’s luscious texture and rich flavor. The custard adds moisture and a delightful creaminess that sets this cake apart from others.
Step 8: Prepare the Cake Pan
Pour the cake batter into a greased 9-inch round cake pan. Use a spatula to smooth the top, ensuring an even surface for baking. This will help your Lemon Custard Cake bake uniformly and prevent any potential sinking.
Step 9: Bake the Cake
Place the pan in the preheated oven and bake for 35-40 minutes or until a toothpick inserted into the center comes out clean. Keep an eye on the cake towards the end of the baking time; it should be golden brown and spring back when lightly pressed.
Step 10: Cool Before Serving
Once baked, carefully remove the cake from the oven and allow it to cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely before slicing. This cooling period is important as it helps set the cake’s structure and enhances its flavor.
Make Ahead Options
These Lemon Custard Cakes are a fantastic choice for meal prep! You can prepare the cake batter up to 24 hours in advance, storing it in an airtight container in the refrigerator to maintain freshness. Additionally, you can make the lemon custard ahead of time; simply refrigerate it for up to 3 days. When you're ready to bake, just pour the batter into your greased cake pan, fold in the prepared lemon custard, and bake as directed. This way, you’ll have a delightful dessert ready with minimal effort, ensuring it's just as delicious as if it were made fresh that day!

Lemon Custard Cake Recipe FAQs
How do I select ripe lemons for this cake?
Absolutely! When choosing lemons, look for ones that are bright yellow, firm, and slightly heavy for their size. Avoid lemons with dark spots or blemishes, as they may be overripe or dry inside. A good rule of thumb is to give them a gentle squeeze; they should yield slightly under pressure, indicating juiciness.
What’s the best way to store leftover Lemon Custard Cake?
Very good question! To keep your Lemon Custard Cake fresh, store it at room temperature for up to 2 days, covered with a clean kitchen towel or in a cake dome. If you'd like to keep it for longer, place it in the fridge, wrapped in plastic wrap or in an airtight container, where it can last for up to 5 days.
Can I freeze slices of Lemon Custard Cake?
Yes, you can! To freeze slices of your Lemon Custard Cake, first, let them cool completely. Then, wrap each slice tightly in plastic wrap, followed by a layer of aluminum foil to prevent freezer burn. Store in the freezer for up to 3 months. When you’re ready to enjoy, just thaw the slices in the fridge overnight or at room temperature for a quick treat!
What if my cake doesn't rise properly?
If you find that your cake hasn’t risen as expected, it could be due to a few factors. Ensure your baking powder is fresh (it should bubble when mixed with a little vinegar or lemon juice). Also, check that you didn’t overmix the batter, which can lead to a dense texture. Finally, make sure your oven is at the correct temperature; using an oven thermometer can help verify its accuracy.
Are there any dietary considerations, like allergies, I should keep in mind?
Certainly! This Lemon Custard Cake contains gluten (from the all-purpose flour) and dairy (from the butter and milk), which may pose issues for those with gluten intolerance or lactose sensitivities. For gluten-free variations, consider using a gluten-free all-purpose flour blend. Additionally, you could substitute coconut milk for regular milk and a dairy-free butter alternative for a dairy-free version. If you’re serving it to pets, make sure to keep it away as cakes are not suitable for animals!
How do I know when my Lemon Custard Cake is fully baked?
Great question! To test for doneness, insert a toothpick into the center of the cake. If it comes out clean or with just a few moist crumbs, your cake is ready. The top should also be golden brown, and the cake should spring back lightly when touched. If it’s still wet, give it a few more minutes in the oven while watching closely!
