It’s sweet, but not too sweet, with a zingy twist. Every bite is a burst of bright flavors. Trust us, once you try it, you’ll want another slice!
Why This Recipe Works
- Tangy Lemon Curd: The star of this cake is undoubtedly the tangy lemon curd, which adds a burst of bright citrus flavor. Made from freshly squeezed lemon juice, zest, and a touch of sweetness, the curd strikes a perfect balance between tart and sweet.
- Cream Cheese Frosting: Smooth and velvety, the cream cheese frosting complements the lemony layers with its rich and luscious taste. Its decadence pairs beautifully with the zesty notes of the lemon curd.
- Moist and Fluffy Cake: The cake layers are moist, tender, and infused with the essence of lemon, thanks to a combination of buttermilk, lemon juice, and lemon zest. The result is a perfectly balanced cake that’s not overly sweet, making it an ideal treat for any occasion.
- Fresh Berry Decoration offers a vibrant and juicy burst of fruity goodness that complements the lemon flavors splendidly.
Ingredient Notes
- All-Purpose Flour: For the best results, use sifted all-purpose flour. Look for reputable brands that offer a fine texture, ensuring a tender and fluffy cake.
- Buttermilk or Milk: Buttermilk adds a delightful tanginess to the cake. For the creamiest and tangiest outcome, opt for full-fat buttermilk. If you don’t have buttermilk on hand, you can substitute it with milk.
- Eggs: Choose large eggs. Always use fresh eggs at room temperature for the best results.
- Sugar: Granulated or superfine/caster sugar are both good options for this recipe.
- Baking Powder and Baking Soda: Choose reliable double-acting baking powder for a consistent rise and fresh baking soda to enhance tenderness. Find these leavening agents in the baking aisle of most grocery stores.
- Lemon Juice and Zest: Use freshly squeezed lemon juice for the freshest flavor. Large, juicy lemons are your best bet for maximum citrusy goodness.
- Vanilla: Vanilla bean paste or pure vanilla extract offers the richest and most authentic flavor. Look for high-quality brands with no artificial additives.
- Cream Cheese: Softened cream cheese is crucial for achieving a smooth and creamy frosting. Brick-style cream cheese works best in this recipe.
- Powdered Sugar: Opt for sifted powdered sugar to avoid lumps in the frosting. Most grocery stores offer standard powdered sugar in the baking aisle. You can find organic powdered sugar or powdered coconut sugar in specialty stores or health food sections if you prefer a healthier alternative.
- Fresh Berries: Choose ripe and plump fresh berries. Strawberries, blueberries, raspberries, or blackberries work wonderfully.
- Butter: Use unsalted butter for both the cake and the lemon curd filling. Unsalted butter allows you to control the amount of salt in the recipe. If you only have salted butter on hand, reduce the amount of added salt in the recipe accordingly.
- Cornstarch: Cornstarch (also known as cornflour) is a thickening agent for the curd. You can find cornstarch in the baking aisle.
Lemons For Baking
When buying lemons for baking with the zest, be sure to choose unwaxed lemons. If your budget permits, opt for organic lemons, as they tend to be juicier and more flavorful. Check the skin for firmness and vibrant color, indicating they are ripe and full of juice.
Step By Step Instructions
Preparation
Preheat your oven to 325°F (160°C). Line your pans with parchment paper and Grease and flour three 9-inch (20cm) round cake pans.
Zesting Your Lemons
Using the zester or microplane, gently run it across the outer surface of the lemon, applying slight pressure. Grate only the yellow part of the skin, avoiding the white pith beneath, as it is bitter.
Continuously rotate the lemon as you zest, ensuring you collect zest from all sides while avoiding the bitter pith.
When using both the lemon zest and lemon juice, be sure to zest the lemons first. Zesting a whole lemon is much easier than trying to zest it after juicing. When the lemon is whole, it is firmer and more stable, making it simpler to run a zester or microplane over the surface to extract the zest.
Juicing The Lemons
For this recipe (including the curd), you will need approximately six lemons. To juice a lemon, start by choosing a ripe and firm lemon. Roll the lemon on a countertop to release more juice.
Cut the lemon in half and hold one half with the cut side up over a small bowl or dish. Firmly squeeze the lemon, rotating it slightly to extract the juice.
Alternatively, take one lemon half and hold it cut side down over the citrus juicer. Press the lemon down firmly on the reamer or cone of the juicer and twist it back and forth while applying pressure. The juicer will extract the lemon juice and flow it down into the collection reservoir below.
Separating An Egg
For this recipe, you will need to separate 1 large egg. To do this, hold the egg firmly but gently and tap gently on a flat surface like the countertop to create a crack in the shell.
Use both hands to open the egg by pulling the two halves of the shell apart. Be cautious not to drop any shell fragments into the egg.
Over the bowl, carefully transfer the egg yolk back and forth between the two shell halves, allowing the egg whites to drip into the bowl. Keep the yolk intact as you transfer it, and let the egg whites fall into the bowl below.
Once the egg white has mostly separated from the yolk, gently transfer the yolk to a separate clean bowl.
Making The Batter
In a medium-sized bowl, whisk together the sifted all-purpose flour (2½ cups or 300g), baking powder (1 teaspoon), baking soda (¼ teaspoon), and salt (½ teaspoon). This blend of dry ingredients will provide structure and flavor to your cake. Set the mixture aside for now; we’ll incorporate it into the wet ingredients later.
Connect your mixer with the whisk attachment and beat the 4 large eggs with 1½ cups (300g) of granulated sugar on high speed. The goal here is to achieve a pale and fluffy consistency, which typically takes about 5 minutes. This airy mixture will ensure a light and delicate cake texture.
Lower the mixer’s speed and slowly add ¾ cup (80ml) of neutral oil (such as canola oil or vegetable oil).
Then continue with the ¼ cup (60g) of melted butter, ¾ cup (180ml) of buttermilk (or milk), ½ cup (120ml) of freshly squeezed lemon juice, 1 tablespoon (6g) of lemon zest, and 1 teaspoon (5ml) of vanilla. Mix until it’s all combined.
Gradually add the flour mixture you set aside earlier and mix until just combined.
Be cautious not to overmix, which could result in a denser cake. Gently combine the ingredients at this stage and mix just until there’s no more dry flour visible.
Divide the cake batter evenly between the two prepared pans.
Slide the pans into the preheated oven and bake for 25-30 minutes. Keep an eye out for a toothpick inserted into the center, which should come out clean or with just a few crumbs.
Once baked, allow the cakes to cool in the pans for 10 minutes. After this short resting period, transfer them to a wire rack to cool completely. This step ensures the cakes maintain their texture and makes removing them from the pans easier.
Making The Lemon Curd Filling
Whisk together 1½ tablespoons (9g) of finely grated lemon zest, 2 large eggs, 1 egg yolk, ½ cup (120ml) of freshly squeezed lemon juice, and ½ teaspoon (1g) of cornstarch in a medium mixing bowl.
Then melt ½ cup (120g) butter in a medium saucepan over medium heat. Stir in ¾ cup (150g) of sugar and ¼ teaspoon (1.5g) of salt Stir until the butter is melted and the sugar is incorporated. The sugar doesn’t need to be dissolved at this point.
Take a small portion of the warm butter mixture and gradually blend it into the egg mixture, whisking continuously. This process, called tempering, prevents the eggs from curdling. Then, pour this tempered egg mixture back into the saucepan and whisk over medium heat until the curd thickens and gently bubbles, about 8 minutes.
To determine if your mixture is properly cooked, use a spoon to scoop some of it and then run your finger across the back of the spoon. The mixture is ready if your finger leaves a clear path that doesn’t fill back in. However, if the path fills in, then you should continue cooking it for a bit longer.
Strain your luscious lemon curd through a sieve into a clean bowl, ensuring a silky texture without any lumps or zest.
Press plastic wrap directly onto the curd’s surface to avoid forming skin. Allow it to cool to room temperature before refrigerating until thoroughly chilled and thickened.

Making The Cream Cheese Frosting
In a large mixing bowl, beat 8 oz (225g) softened cream cheese and 1 cup (225g) of butter together using an electric mixer on medium speed. This blending creates a velvety base for your frosting.
Mix in 1 teaspoon (5ml) vanilla and a pinch of salt. Then gradually introduce the sifted powdered sugar (you’ll need about 4 cups or 500g), adding one cup at a time.
Mix on low speed after each addition until the sugar is fully incorporated. This gradual approach prevents clumps and guarantees a smooth frosting.
If the frosting seems too thick or you prefer a softer consistency, you can add a few tablespoons of milk or heavy cream (the equivalent of 45-60ml). Start with one tablespoon at a time, and mix well until you achieve the desired consistency.
Assembling the Cake
Place one of the cake layers on a cake stand or serving plate. Pipe the cream cheese frosting around the edge of the bottom layer. Then fill the center of the piped frosting with lemon curd.
Spread the frosting on the top and then onto the sides of the cake.
For a semi-naked look, use a bench scraper or an offset spatula to gently scrape off some of the frosting around the sides of the cake until you achieve the desired effect.
Decorate the top of the cake as desired with fresh berries, edible flowers, or any other decorations of your choice. This adds a final touch of elegance and flavor.
Once the cake is decorated, refrigerate it for at least 30 minutes to set the frosting before serving.

- Softened Cream Cheese and Butter: For the frosting, make sure your cream cheese and butter are fully softened to avoid lumps.
- Gradual Sugar Addition: Add powdered sugar to the frosting gradually to avoid sugar clouds and ensure a smooth mixture.
- Texture Adjustment: If your frosting is too thick, add a little milk or cream a tablespoon at a time until you achieve the desired consistency.
- Frosting Technique: Apply a thin crumb coat layer of frosting before the final layer to lock in any cake crumbs and create a smooth base.
- Decoration Choices: Customize the cake’s appearance with your favorite fruits, berries, edible flowers, or other decorations. Get creative!
- Chill for Setting: Allow the cake to chill in the refrigerator for at least 30 minutes before serving. This helps the frosting set and enhances the flavors.
Storage & Freezing Instructions
Store the assembled cake in the refrigerator for up to 3 days, tightly wrapped in plastic or airtight containers.
Freezing: If possible, freeze the cake layers without the cream cheese frosting. The frosting can become slightly compromised in texture after freezing and thawing.
To freeze the unfrosted cake layers for up to 3 months, tightly wrapped in plastic wrap and foil. Thaw in the refrigerator before frosting.
