Why This Lemon Layer Cake Recipe Works

This Lemon Layer Cake recipe is designed for success, and it stands out for several reasons:

• Balance of Flavors: The recipe carefully balances sweetness with the tartness of lemon. It uses lemon zest and juice in multiple components to create a layered lemon flavor profile, ensuring the cake isn’t overly sweet or overwhelmingly tart.
• Moist and Tender Cake: The use of buttermilk and oil contributes to a wonderfully moist cake crumb that stays tender for days. The creaming method, properly executed, incorporates air into the batter, resulting in a light and airy texture.
• Stable and Flavorful Buttercream: The Swiss meringue buttercream is known for its silky smooth texture and ability to hold its shape, making it perfect for decorating layer cakes. The addition of lemon curd and zest to the buttercream amplifies the lemon flavor without making it too acidic.
• Detailed Instructions: The recipe provides clear, step-by-step instructions with tips and tricks to guide bakers of all levels. It addresses common baking pitfalls and offers solutions to ensure a successful outcome.
• Make-Ahead Options: The different components of the cake (cake layers, lemon curd, buttercream) can be made ahead of time, making it easier to assemble the cake on the day of serving.

Key Ingredients for the Perfect Lemon Layer Cake

Before we dive into the recipe, let’s take a closer look at the key ingredients that make this Lemon Layer Cake so special:

• All-Purpose Flour: Provides structure to the cake. Measure accurately using the spoon and level method (spoon flour into the measuring cup and level off with a knife) to avoid a dense cake.
• Baking Powder and Baking Soda: Leavening agents that help the cake rise. Ensure they are fresh for optimal results.
• Salt: Enhances the flavors of the other ingredients and balances the sweetness.
• Unsalted Butter: Use softened butter for the cake batter and cold butter for the Swiss meringue buttercream. The butter provides richness and flavor.
• Granulated Sugar: Sweetens the cake and contributes to its tender texture.
• Eggs: Add moisture, richness, and structure to the cake. Use large eggs at room temperature for best results.
• Vegetable Oil: Contributes to the cake’s moistness.
• Buttermilk: Adds a tangy flavor and tenderizes the cake. If you don’t have buttermilk, you can make a substitute by adding 1 tablespoon of lemon juice or white vinegar to 1 cup of milk.
• Lemon Zest: Adds a concentrated lemon flavor to the cake and buttercream. Use a microplane to zest the lemons without getting the bitter white pith.
• Lemon Juice: Provides a tangy flavor to the cake, lemon curd, and buttercream. Use fresh lemon juice for the best flavor.
• Lemon Curd: A luscious lemon-flavored custard that adds a layer of intense lemon flavor and moisture to the cake.
• Egg Yolks: Used in the lemon curd to create a rich and creamy texture.
• Powdered Sugar: Sweetens the Swiss meringue buttercream and helps to stabilize it.

Equipment You’ll Need

To bake this Lemon Layer Cake, you’ll need the following equipment:

• Three 8-inch Round Cake Pans: Ensure they are the same size for even baking.
• Parchment Paper: To line the cake pans and prevent sticking.
• Mixing Bowls: For preparing the cake batter, lemon curd, and buttercream.
• Electric Mixer: A stand mixer or hand mixer will make the process easier.
• Rubber Spatula: For scraping down the sides of the bowls and folding ingredients.
• Whisk: For whisking the dry ingredients and lemon curd.
• Saucepan: For making the lemon curd.
• Double Boiler or Heatproof Bowl and Saucepan: For cooking the Swiss meringue.
• Candy Thermometer: To monitor the temperature of the Swiss meringue.
• Offset Spatula: For frosting the cake.
• Piping Bag and Tips (Optional): For decorating the cake.

Lemon Layer Cake Recipe

Now, let’s get to the heart of the matter – the recipe itself! This recipe is broken down into three main components: the lemon cake layers, the lemon curd filling, and the lemon buttercream frosting. Follow each step carefully, and you’ll be well on your way to creating a stunning Lemon Layer Cake.

Part 1: Lemon Cake Layers

Yields: 3 8-inch cake layers
Prep time: 30 minutes
Bake time: 28-32 minutes

Ingredients:

• 2 ½ cups (300g) all-purpose flour
• 2 ½ teaspoons baking powder
• ½ teaspoon baking soda
• ½ teaspoon salt
• 1 cup (226g) unsalted butter, softened
• 1 ¾ cups (350g) granulated sugar
• 3 large eggs, at room temperature
• 1/2 cup (120ml) vegetable oil
• 1 cup (240ml) buttermilk, at room temperature
• 2 tablespoons lemon zest
• 2 tablespoons lemon juice
• 1 teaspoon vanilla extract

Instructions:

1. Preheat oven and prepare pans: Preheat oven to 350°F (175°C). Grease and flour three 8-inch round cake pans. Line the bottoms with parchment paper circles. This ensures the cakes release cleanly.
2. Whisk dry ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, and salt. This ensures the leavening agents are evenly distributed throughout the flour.
3. Cream butter and sugar: In the bowl of a stand mixer fitted with the paddle attachment, cream together the softened butter and granulated sugar until light and fluffy. This usually takes about 3-5 minutes. Scrape down the sides of the bowl as needed. Properly creaming the butter and sugar is crucial for incorporating air into the batter, resulting in a light and airy cake.
4. Add eggs: Add the eggs one at a time, beating well after each addition. This allows each egg to fully emulsify into the batter.
5. Add oil: Pour in the vegetable oil and mix until combined.
6. Combine wet and dry ingredients: Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined. Be careful not to overmix, as this can develop the gluten in the flour and result in a tough cake.
7. Add lemon zest, juice, and vanilla: Stir in the lemon zest, lemon juice, and vanilla extract.
8. Divide batter: Divide the batter evenly among the prepared cake pans.
9. Bake: Bake for 28-32 minutes, or until a wooden skewer inserted into the center comes out clean.
10. Cool: Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.
11. Level (Optional): Once completely cool, use a serrated knife to level the tops of the cakes if necessary.

Part 2: Lemon Curd Filling

Yields: About 2 cups
Prep time: 15 minutes
Cook time: 10-15 minutes

Ingredients:

• 1 cup (200g) granulated sugar
• ½ cup (113g) unsalted butter, cut into cubes
• 4 large egg yolks
• ½ cup (120ml) lemon juice
• 2 tablespoons lemon zest
• Pinch of salt

Instructions:

1. Combine ingredients: In a medium saucepan, combine the sugar, butter, egg yolks, lemon juice, lemon zest, and salt.
2. Cook over medium heat: Cook over medium heat, stirring constantly with a whisk, until the mixture thickens enough to coat the back of a spoon. This usually takes about 10-15 minutes. Be patient and keep stirring to prevent the eggs from scrambling. The curd is ready when you can run your finger across the back of the spoon and the line holds its shape.
3. Strain (Optional): For a smoother curd, strain the mixture through a fine-mesh sieve into a clean bowl.
4. Cool: Press plastic wrap directly onto the surface of the curd to prevent a skin from forming. Refrigerate for at least 2 hours, or until completely cool. The curd will thicken as it cools.

Part 3: Lemon Buttercream Frosting

This recipe uses a Swiss meringue buttercream, which is stable, smooth, and not too sweet. It’s perfect for frosting layer cakes.

Yields: About 6 cups
Prep time: 20 minutes
Cook time: 5-10 minutes

Ingredients:

• 6 large egg whites
• 1 ½ cups (300g) granulated sugar
• 1 ½ cups (340g) unsalted butter, cold and cut into cubes
• ¼ teaspoon salt
• 1 teaspoon vanilla extract
• ½ cup Lemon Curd (prepared above)
• 1 tablespoon lemon zest

Instructions:

1. Combine egg whites and sugar: In the bowl of a stand mixer (or a heatproof bowl set over a saucepan of simmering water, creating a double boiler), combine the egg whites and sugar.
2. Heat and whisk: Cook over low heat, whisking constantly, until the sugar is completely dissolved and the mixture reaches 160°F (71°C) on a candy thermometer. This step is crucial for pasteurizing the egg whites and creating a stable meringue.
3. Whip meringue: Remove the bowl from the heat (or transfer to the stand mixer if using a double boiler). Using the whisk attachment, whip the egg whites on high speed until stiff, glossy peaks form and the bowl is cool to the touch. This can take 5-10 minutes.
4. Add butter: With the mixer on medium speed, gradually add the cold butter, a few cubes at a time, allowing each addition to incorporate fully before adding more. The mixture may look curdled at first, but keep mixing, and it will eventually come together into a smooth buttercream.
5. Add salt and vanilla: Add the salt and vanilla extract and mix until combined.
6. Add lemon curd and zest: Gently fold in the prepared lemon curd and lemon zest. Be careful not to overmix, as this can deflate the buttercream.

Assembling the Lemon Layer Cake

Now that you’ve prepared all the components, it’s time to assemble the Lemon Layer Cake!

1. Place first layer: Place one cake layer on a cake stand or serving plate.
2. Spread lemon curd: Spread a generous layer of lemon curd over the cake layer.
3. Add buttercream: Spread a layer of lemon buttercream over the lemon curd.
4. Repeat: Repeat with the remaining cake layers, lemon curd, and buttercream.
5. Crumb coat: Apply a thin layer of buttercream over the entire cake to seal in any crumbs. This is called a crumb coat. Refrigerate the cake for 30 minutes to allow the crumb coat to set.
6. Final frosting: Apply a final layer of buttercream over the entire cake, smoothing it out with an offset spatula.
7. Decorate: Decorate the cake as desired. You can use piping tips to create decorative borders or swirls, or simply sprinkle the cake with lemon zest or candied lemon slices.
8. Chill: Refrigerate the cake for at least 30 minutes before serving to allow the buttercream to set.

Tips for Success

Here are a few extra tips to ensure your Lemon Layer Cake is a resounding success:

• Measure ingredients accurately: Baking is a science, so accurate measurements are essential. Use a kitchen scale for the most precise results.
• Use room temperature ingredients: Room temperature ingredients emulsify better and create a smoother batter.
• Don’t overmix the batter: Overmixing develops the gluten in the flour, resulting in a tough cake. Mix until just combined.
• Cool cakes completely before frosting: Frosting a warm cake will cause the buttercream to melt.
• Use a cake turntable: A cake turntable makes frosting and decorating the cake much easier.
• Chill the cake between layers: Chilling the cake between layers helps the buttercream set and prevents the cake from sliding.

Variations and Substitutions

Want to put your own spin on this Lemon Layer Cake? Here are a few variations and substitutions you can try:

• Add berries: Incorporate fresh berries, such as raspberries, blueberries, or strawberries, into the lemon curd filling or as a garnish.
• Make it a lemon poppy seed cake: Add 2 tablespoons of poppy seeds to the cake batter.
• Substitute gluten-free flour: Use a gluten-free all-purpose flour blend to make a gluten-free Lemon Layer Cake.
• Add a lemon syrup soak: Brush the cake layers with a simple lemon syrup (equal parts lemon juice and sugar, heated until the sugar dissolves) before frosting for an extra burst of lemon flavor and moisture.
• Change the frosting: Instead of Swiss meringue buttercream, you could use cream cheese frosting, Italian meringue buttercream, or even a simple glaze.

Make-Ahead Instructions

This Lemon Layer Cake can be made ahead of time, which is perfect for busy schedules.

• Cake layers: The cake layers can be baked up to 2 days in advance. Wrap them tightly in plastic wrap and store them at room temperature.
• Lemon curd: The lemon curd can be made up to 1 week in advance. Store it in an airtight container in the refrigerator.
