A Light and Lovely Tea Time Treat

Sometimes the most elegant desserts are the simplest ones. I first fell in love with a traditional sponge cake during a quiet afternoon tea with an old friend. It was so remarkably light, airy, and not overly sweet.

I realized it was the absolute perfect vehicle for showcasing a really vibrant, homemade filling. That realization led to this simple yet stunning Lemon curd cake, which has since become a cherished favorite in my collection of Lemon desserts.

Why This Classic is Always a Good Idea

You will adore this recipe because it relies on classic techniques to create something truly special. Here is why this Lemon curd cake is so wonderful:

• The Airy Sponge: The cake relies purely on whipped eggs for its rise, resulting in a cloud like texture that is incredibly delicate.
• The Perfect Pairing: Because the sponge itself is quite plain and only mildly sweet, it lets the sharp, zesty flavor of the citrus filling take center stage.
• A Beautiful Canvas: It is sturdy enough to hold the thick filling, yet light enough that you will definitely want a second slice.

Everything You Need

• 1 cup all-purpose flour: Spooned and leveled. Sift it twice for the lightest possible crumb.
• 4 large eggs: They must be at room temperature to whip to their maximum volume.
• 3/4 cup granulated sugar: Superfine sugar works best here if you have it, as it dissolves faster into the eggs.
• 1 teaspoon vanilla extract: For a warm background note.
• 2 tablespoons unsalted butter: Melted and slightly cooled. This adds just a touch of richness and keeps the crumb tender.
• 1 cup Lemon Curd: A high quality, thick store bought or homemade filling to sandwich between the layers.

Crafting Your Cake

• STEP 1Prepare two 8 inch round cake pans by greasing the bottoms and lining them with parchment paper. Do not grease the sides; the batter needs to grip the pan to climb.
• STEP 2In the bowl of a stand mixer fitted with the whisk attachment, beat the room temperature eggs and granulated sugar on high speed for a full 8 to 10 minutes. The mixture will triple in volume, turn very pale yellow, and leave a thick ribbon trail when the whisk is lifted.
• STEP 3Gently beat in the vanilla extract just until combined.
• STEP 4Sift the all purpose flour over the egg mixture in three batches. After each addition, use a large rubber spatula to very gently fold the flour in, using an under and over motion to preserve as much air as possible.
• STEP 5Take one cup of the batter and gently fold it into the cooled, melted butter in a separate small bowl. Once combined, gently fold this butter mixture back into the main batter.
• STEP 6Divide the batter evenly between the prepared pans. Bake at 350 degrees Fahrenheit for 20 to 25 minutes, or until the tops are golden and spring back when lightly touched.
• STEP 7Let the cakes cool in the pans for 10 minutes before turning them out onto a wire rack to cool completely.
• STEP 8To assemble, place one layer on a serving plate. Spread the thick lemon curd evenly over the top, leaving a small border around the edge. Carefully place the second layer on top and give it a very light press.

Fun Twists and Serving Ideas

• Snowy Finish: The most classic way to serve this is with a very generous dusting of powdered sugar over the top layer just before slicing.
• Whipped Cream Crown: Serve each slice with a dollop of unsweetened or very lightly sweetened whipped cream to cut the tartness of the filling.
• Macerated Strawberries: Spoon fresh strawberries, tossed with a little sugar and left to sit for 30 minutes, over the slices for a beautiful summer presentation.
• Lemon Syrup Soak: Before filling, brush both cake layers with a simple syrup made of equal parts sugar, water, and fresh lemon juice to make the sponge exceptionally moist.

Ingredients

  

Sponge Cake

• 1 cup all-purpose flour spooned and leveled; sift twice
• 4 large eggs room temperature
• 3/4 cup granulated sugar superfine sugar can also be used
• 1 tsp vanilla extract
• 2 tbsp unsalted butter melted and slightly cooled

Lemon Curd Filling

• 1 cup lemon curd thick, store-bought or homemade

Equipment

• Two 8-inch Round Cake Pans
• Stand Mixer with Whisk Attachment
• Large Mixing Bowl
• Small Mixing Bowl
• Rubber Spatula
• Fine mesh sieve
• Wire rack
• Parchment paper

Method

 

1. Preheat the oven to 350°F (177°C). Grease the bottoms of two 8-inch round cake pans and line them with parchment paper. Do not grease the sides, so the sponge batter can grip the pans as it rises.
2. Using a stand mixer fitted with the whisk attachment, beat the room-temperature eggs and sugar on high speed for 8 to 10 minutes. The mixture should triple in volume, become very pale, and leave a thick ribbon trail when the whisk is lifted.
3. Gently beat in the vanilla extract just until combined.
4. Sift the flour over the egg mixture in three batches. After each addition, gently fold with a large rubber spatula using an under-and-over motion, preserving as much air as possible.
5. Place about 1 cup of the batter in a small bowl and gently fold in the melted, slightly cooled butter. Carefully fold this mixture back into the main batter until evenly incorporated.
6. Divide the batter evenly between the prepared cake pans. Bake for 20 to 25 minutes, or until the tops are golden and spring back when lightly touched. Avoid opening the oven during the first 15 minutes.
7. Allow the cakes to cool in their pans for 10 minutes. Carefully turn them out onto a wire rack, remove the parchment paper, and let them cool completely.
8. Place one cooled sponge layer on a serving plate. Spread the lemon curd evenly over the top, leaving a small border around the edge. Carefully position the second layer on top and press very lightly to secure.

Notes

For a classic finish, dust the top generously with powdered sugar just before serving. You can also serve slices with lightly sweetened whipped cream or fresh strawberries that have been tossed with a little sugar and rested for 30 minutes.

For extra moisture and citrus flavor, brush both sponge layers with a simple syrup made from equal parts sugar, water, and fresh lemon juice before adding the filling.

Whipping the eggs thoroughly to the ribbon stage is essential because they provide the cake’s only lift. Fold the flour gently to preserve the air in the batter, and make sure the sponge layers are completely cool before filling.

Unfilled sponge layers can be wrapped tightly and stored at room temperature overnight. They can also be frozen, wrapped in plastic and foil, for up to 2 months. Store the assembled cake in an airtight container in the refrigerator for up to 3 days. Let it stand at room temperature for about 30 minutes before serving.

Pro Tips

• Whip the Eggs Completely: Do not cut the 8 to 10 minute whipping time short. The air trapped in the eggs is the only leavening agent in this cake, so it must reach the “ribbon stage.”
• Fold With Care: When folding in the flour, be incredibly gentle. If you mix too vigorously, you will knock the air out of the batter and the cake will be dense and rubbery.
• Do Not Open the Oven: Avoid opening the oven door during the first 15 minutes of baking, or the sudden drop in temperature could cause the delicate sponge to collapse.
• Sift Your Flour: Sifting the flour twice before folding it in ensures there are no heavy lumps that will sink to the bottom of the batter.
• Cool Completely Before Filling: If the sponge layers are even slightly warm when you assemble them, the filling will melt and seep into the cake, making it soggy.

FAQs

Can I make the sponge layers ahead of time? Yes. You can bake the layers, cool them completely, wrap them tightly in plastic wrap, and store them at room temperature overnight.

How do I store the assembled cake? Because of the filling, store the cake in the refrigerator in an airtight container for up to 3 days. Let it sit at room temperature for 30 minutes before serving for the best texture.

Why did my sponge cake turn out dense and flat? This usually happens if the eggs were not whipped long enough, or if the batter was folded too aggressively when adding the flour, knocking out the trapped air.

Can I freeze a sponge cake? Yes, the unfilled layers freeze beautifully. Wrap them tightly in plastic and then foil, and freeze for up to 2 months.

Can I use this recipe for a rolled cake? This batter is a bit too delicate to roll easily without cracking. It is best used for flat, stacked layers.
