Ingredients

Cake

  • 2 cups all-purpose flour
  • 1 1/2 cups granulated sugar
  • 1 tablespoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup vegetable oil
  • 7 large eggs, separated
  • 3/4 cup fresh lemon juice
  • 2 tablespoons lemon zest
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon cream of tartar

Blueberry-Coriander Jam

  • 2 cups fresh blueberries
  • 1/2 cup granulated sugar
  • 1 teaspoon ground coriander
  • 1 tablespoon lemon juice

Meyer Lemon Curd

  • 3 large eggs
  • 1/2 cup granulated sugar
  • 1/2 cup fresh Meyer lemon juice
  • 1/4 cup unsalted butter, cut into pieces

Blueberry-Coriander Buttercream

  • 5 large egg whites
  • 1 1/4 cups granulated sugar
  • 1 1/2 cups unsalted butter, softened
  • 1/2 cup prepared blueberry-coriander jam

Directions

Step 1: Make the Cake

Preheat oven to 350°F. Grease and line two 9-inch cake pans with parchment paper. In a large bowl, whisk together flour, sugar, baking powder, and salt. In a separate bowl, whisk egg yolks, oil, lemon juice, zest, and vanilla. Gradually mix wet ingredients into dry ingredients.

Step 2: Whip Egg Whites

In a separate clean bowl, beat egg whites with cream of tartar until stiff peaks form. Gently fold into the batter. Divide the batter between prepared pans and bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean. Let cool completely.

Step 3: Make the Blueberry-Coriander Jam

In a saucepan, combine blueberries, sugar, coriander, and lemon juice. Cook over medium heat until berries burst and the mixture thickens, about 15 minutes. Let cool completely.

Step 4: Make the Lemon Curd

In a heatproof bowl over a double boiler, whisk eggs, sugar, and lemon juice. Cook until thickened, about 10 minutes. Remove from heat and whisk in butter until smooth. Chill before using.

Step 5: Make the Buttercream

In a heatproof bowl, whisk egg whites and sugar over a double boiler until sugar dissolves. Transfer to a stand mixer and whip until stiff peaks form. Gradually add softened butter and beat until smooth. Fold in blueberry-coriander jam.

Step 6: Assemble the Cake

Spread lemon curd between cake layers. Frost the entire cake with blueberry-coriander buttercream. Garnish with edible flowers, fresh berries, and citrus slices.

The Magic of Chiffon Cake – Why It’s So Light and Airy

Chiffon cake is unique because it combines elements of both sponge cake and butter cake. It has the light, airy texture of a sponge cake but also includes oil, which gives it a moist and tender crumb. Here’s why chiffon cake stands out:

  • Whipped Egg Whites: Beaten egg whites are folded into the batter, incorporating air and making the cake incredibly light.
  • Oil-Based Moisture: Unlike butter-based cakes, which can feel denser, oil keeps chiffon cakes soft even after refrigeration.
  • Balanced Sweetness: This cake is subtly sweet, making it an ideal base for tangy lemon curd and a richly flavored buttercream.

Why Lemon is the Perfect Flavor for Chiffon Cake

Lemon enhances the freshness of the cake and balances out the sweetness of the frosting. Using both lemon juice and lemon zest maximizes the citrus flavor while keeping it naturally bright and fragrant. Meyer lemons, which are slightly sweeter and more floral than regular lemons, make the curd especially smooth and flavorful.

A Unique Twist – Blueberry-Coriander Buttercream

The real surprise in this cake is the blueberry-coriander buttercream. While blueberries add a deep fruitiness, coriander enhances their flavor with a subtle, citrusy, and slightly spicy note. The result is a frosting that’s both bold and delicate, complementing the lemon cake beautifully.

  • Swiss Meringue Base: This buttercream is made using Swiss meringue, which involves gently heating egg whites and sugar before whipping them into a silky frosting. The result is a stable, smooth, and less sweet buttercream that holds up well to decorating.
  • Natural Color and Flavor: The blueberry jam gives the frosting a gorgeous natural hue and an intense berry flavor without artificial coloring.
  • Coriander’s Role: Ground coriander might not be a typical frosting ingredient, but its citrusy undertones enhance the blueberries and tie in seamlessly with the lemon cake.

Making the Perfect Meyer Lemon Curd

Lemon curd is an essential layer in this cake, adding a creamy, tangy contrast to the sweet and airy cake layers. Here’s what makes a great lemon curd:

  • Use Fresh Meyer Lemons: They offer a smoother, sweeter citrus flavor that balances acidity without being overpowering.
  • Cook Low and Slow: Making lemon curd over a double boiler prevents the eggs from scrambling and ensures a silky consistency.
  • Strain for Extra Smoothness: Running the curd through a fine-mesh sieve removes any bits of egg, creating a perfectly smooth filling.

Assembling the Cake – Creating a Showstopping Presentation

Once all the components are prepared, assembling the cake is where the magic happens. Here’s how to achieve a stunning final product:

  • Even Layers: Use a serrated knife to trim the cake layers if necessary to ensure a level surface.
  • Lemon Curd Filling: Spread an even layer of curd between the cake layers to add brightness and contrast.
  • Smooth Frosting Application: Swiss meringue buttercream is easier to spread when slightly softened. Use an offset spatula to achieve a smooth finish.
  • Decorate with Fresh Elements: Edible flowers, fresh blueberries, and thin slices of lemon or citrus zest add natural beauty to the cake.

Why This Cake is Perfect for Special Occasions

This lemon chiffon cake isn’t just about taste—it’s about creating a centerpiece for any gathering. Here’s why it’s ideal for celebrations:

  • Elegant Appearance: The pastel hues from the blueberry frosting and the vibrant garnishes make it visually stunning.
  • Delicate Yet Rich Flavor: The balance of light cake, tangy curd, and creamy frosting means it never feels too heavy.
  • Stable and Easy to Slice: Swiss meringue buttercream holds up well, making this cake easy to serve without falling apart.

Pairing and Serving Suggestions

This cake pairs beautifully with beverages and side accompaniments that enhance its flavors:

  • Earl Grey or Chamomile Tea: The floral notes of these teas complement the citrus and berry flavors of the cake.
  • Sparkling Lemonade or Prosecco: A light, bubbly drink balances the richness of the buttercream.
  • Fresh Whipped Cream: A dollop of unsweetened whipped cream adds an extra layer of softness without overpowering the cake.

Tips for Success – How to Make the Perfect Lemon Chiffon Cake

To achieve the best results, follow these expert tips:

  • Room Temperature Ingredients: Eggs, butter, and milk should be at room temperature for even mixing and a smooth batter.
  • Whip the Egg Whites Properly: Stiff peaks should hold their shape but not be dry—over-whipping can cause the cake to lose moisture.
  • Fold Gently: When incorporating egg whites, fold them in with a light hand to preserve the airiness of the batter.
  • Chill the Buttercream Before Using: Swiss meringue buttercream spreads best when slightly cool but not too firm.
  • Refrigerate Before Slicing: Chilling the assembled cake for about 30 minutes before slicing makes for cleaner cuts.

Customizing the Recipe – Variations and Substitutions

This cake is adaptable, and you can tweak it to suit your preferences:

  • Swap the Blueberries for Another Berry: Raspberries, blackberries, or strawberries can replace blueberries for a different flavor twist.
  • Use Orange or Lime Instead of Lemon: Citrus variations can create a unique take on the classic chiffon cake.
  • Make it Gluten-Free: Substitute a gluten-free all-purpose flour blend for a gluten-free version.
  • Add a Crunchy Topping: Toasted almonds or crushed pistachios can add a textural contrast to the soft cake.
