Ingredients You’ll Need
Every ingredient in this recipe is straightforward and significant, ensuring that each bite offers the perfect harmony of flavor and texture. These commonly found pantry staples come together to create the delightful custard cake’s tender crumb, fresh lemon zing, and creamy finish.
- Unsalted butter (1/2 cup): Softened to create a smooth base and add richness without overpowering the lemon flavor.
- Granulated sugar (1 cup): Sweetens the cake and helps achieve that tender, fluffy texture when creamed with butter.
- Large eggs (3): Bind ingredients and build structure, essential for that custard-like consistency inside the cake.
- Milk (1 cup): Adds moisture and contributes to the custard quality beneath the cake layer.
- Lemon zest (1 tablespoon): Infuses bright, citrusy aroma and intense lemon flavor without extra acidity.
- Freshly squeezed lemon juice (1/4 cup): Provides tangy freshness that wakes up your taste buds with every bite.
- Vanilla extract (1 teaspoon): Balances lemon’s acidity with a warm sweet note.
- All-purpose flour (1 cup): The backbone for the cake, offering tender crumb with enough body to support the custard layer.
- Salt (1/4 teaspoon): Enhances all the flavors and balances the sweetness.
- Baking powder (1/4 teaspoon): Helps the cake rise lightly, keeping it delicate yet structured.
- Powdered sugar (optional): For a pretty dusting that adds just a touch of extra sweetness and presentation flair.
How to Make Lemon Custard Cake – A Deliciously Zesty Treat Recipe
Step 1: Preheat and Prepare
Start by heating your oven to 350°F (175°C). Grease a 9-inch round baking dish or pie dish thoroughly to prevent sticking and help your custard cake come out effortlessly after baking.
Step 2: Cream Butter and Sugar
In a large bowl, beat together the softened butter and granulated sugar until the mixture becomes light, airy, and fluffy, which usually takes about 3 minutes. This step is crucial for a tender cake texture.
Step 3: Add Eggs and Flavorings
Beat the eggs in one at a time, mixing well after each addition to ensure the batter emulsifies properly. Stir in the lemon zest, freshly squeezed lemon juice, and vanilla extract, infusing the batter with its signature zesty and aromatic qualities.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, salt, and baking powder. This mix ensures even leavening and seasoning across the cake.
Step 5: Bring Batter Together
Gradually add the dry ingredients to the wet ingredients, mixing just enough to combine — over-mixing can make the cake tough. Then pour in the milk and stir until the batter is smooth, silky, and ready for the oven.
Step 6: Pour Batter into Dish
Transfer the runny batter into the prepared baking dish. Don’t be alarmed by its loose consistency; this is normal and key to developing the custard layer during baking.
Step 7: Bake to Perfection
Bake for about 45 minutes or until the top turns a lovely golden brown and a toothpick inserted near the center comes out clean. As the cake bakes, a luscious custard-like layer will form on the bottom, creating that irresistible texture contrast.
Step 8: Cool and Serve
Allow the cake to cool for 10 minutes before slicing. If you like, dust the top with powdered sugar for a pretty finish. Serve warm or at room temperature to fully enjoy the creamy custard and zesty lemon flavors.

Garnishes
A simple dusting of powdered sugar is classic, but fresh lemon slices or a sprinkle of finely chopped mint can add a refreshing visual pop. For a little indulgence, a dollop of whipped cream or a drizzle of honey complements the tangy cake beautifully.
Side Dishes
This cake pairs wonderfully with a light fruit salad featuring berries or kiwi, which enhance the zesty lemon notes. For an afternoon tea, offer it alongside chamomile or green tea to balance the richness with soothing flavors.
Creative Ways to Present
Try serving your Lemon Custard Cake in individual ramekins for charming individual portions, perfect for dinner parties. Alternatively, top slices with a scoop of vanilla ice cream or lemon sorbet for a cool, creamy contrast that elevates this zesty treat to the next level.
Make Ahead and Storage
Storing Leftovers
Keep any leftover Lemon Custard Cake covered in the refrigerator for up to 3 days. The custard layer remains delightfully creamy, and the cake holds its moisture well when sealed properly with plastic wrap or stored in an airtight container.
Freezing
You can freeze slices of the cake by wrapping them tightly in plastic wrap and placing them in a freezer bag for up to 2 months. Thaw overnight in the refrigerator for best results, then bring to room temperature before enjoying.
Reheating
Gently warm slices in a microwave for 15-20 seconds or place them in a low oven (about 300°F/150°C) wrapped in foil for 10 minutes to revive that fresh-baked sensation. Avoid overheating to keep the custard from drying out.
FAQs
Can I use lemon extract instead of fresh lemon juice?
While lemon extract can be used, fresh lemon juice offers a brighter and more natural lemon flavor that truly makes the cake shine. If you substitute, reduce the amount to avoid overpowering the custard’s balance.
Is this recipe gluten-free friendly?
This particular recipe uses all-purpose flour, so it isn’t gluten-free as is. However, you can try substituting a gluten-free flour blend designed for baking, though textures may vary slightly.
What causes the custard layer in this cake?
The custard layer forms due to the higher liquid content (milk and lemon juice) combined with eggs gently cooking beneath the cake’s fluffy top, creating that dreamy creamy texture without separating.
Can I halve or double this recipe?
Absolutely! The ingredients scale well for smaller or larger servings. Just adjust baking times slightly—the smaller cake may bake faster, while a larger one might require some extra time.
What’s the best way to zest a lemon for this recipe?
Use a microplane or fine grater to zest only the yellow part of the lemon peel, avoiding the bitter white pith. This ensures the best fresh citrus aroma without any bitterness.
