Lemon Meringue Cake

This Lemon Meringue Cake combines the best elements of a classic lemon meringue pie with the elegance of a layered sponge cake! Two layers of buttery lemon sponge are sandwiched with Swiss meringue buttercream, and a zesty lemon curd filling. The cake is topped with swirls of toasted meringue for a crisp, cloud-like finish. The result is a beautifully light lemon meringue cake offering the perfect balance of sweetness and fresh zingy flavour.

Starting by making the Lemon Sponge Cakes

A light and buttery lemon sponge is the foundation of this lemon meringue cake. My recipe follows a basic sponge method with equal parts butter, sugar and flour, plus four large eggs. We also add a teaspoon of baking powder for extra lift, a splash of milk for a fluffier texture, and the zest and juice of one lemon for that fresh zingy flavour. Combine the ingredients to make a smooth cake mixture, and then divide it evenly between two 8-inch round cake tins. Make sure the tins are at least 6cm deep.

Pro Tip: Use Cake Strips for an Even Rise

When it comes to filling and stacking layer cakes, it’s much easier if the cakes have a flat top. This is where cake strips come in handy. The cake strips are soaked in water, and secured around the tins before the cakes go in the oven. The moisture from the cake strips keeps the outer edge of the tin cooler, allowing the cake mixture to bake more evenly, and rise with a flat top.

Quick Note on the Baking Time

For this recipe, I’ve suggested a baking time of 35-45 minutes at 160°C (fan oven). If your oven tends to cook quickly/runs hot, check on the cake after 35 minutes. On the flip side, if your oven cooks slowly/runs cool, bake for 40-45 minutes. Using cake strips? Your cake will take longer than normal to bake. I’d suggest somewhere around 45 minutes.

Pair This Lemon Cake with Swiss Meringue Buttercream

Swiss meringue buttercream is fluffy, light, and not too sweet – perfect for this lemon cake. It takes a little extra effort but is so worth it!

How to Make It:

1. Whisk egg whites and sugar over a bain-marie until the sugar dissolves and the mixture is warm.
2. Whisk the mixture to stiff glossy peaks (takes around 10 minutes).
3. Set aside half of the meringue for piping swirls later.
4. Gradually add butter to the remaining meringue, beating until smooth.
5. Mix in vanilla and salt for flavour balance.

For a simpler option, pair this lemon meringue cake with fresh whipped cream or my lemon buttercream.

How To Fill & Assemble The Cake

First gather all the bits and bobs: lemon cake layers, Swiss meringue buttercream, a piping bag fitted with a star nozzle and filled with meringue, lemon curd, whole lemon, blowtorch and grater. Then, follow these steps:

1. First level the cakes: If needed, use a knife to trim the tops so they’re flat and even.
2. Spread buttercream on top: Spread a layer of swiss meringue buttercream on top of one sponge.
3. Pipe a border: Pipe two rings of buttercream around the edge. This will hold the lemon curd in place and stop the top sponge from sliding off!
4. Fill with lemon curd: Fill the middle with four tablespoons of lemon curd.
5. Add the next layer: Turn the second sponge upside down and carefully place it on top.
6. Top with buttercream: Spread another layer of swiss meringue buttercream on top.

The Finishing Touches

For a beautifully decorated cake, start by grating fresh lemon zest directly over the top. This adds an extra pop of citrus aroma and makes the cake look fresh and vibrant.

Next, take the reserved meringue and pipe elegant swirls around the top of the cake. A large star nozzle works perfectly for this. Hold the bag upright and apply even pressure as you swirl upwards to form peaks. Once all the swirls are piped, use a kitchen blowtorch to lightly toast them until golden brown, creating a gorgeous caramelised effect that adds depth of flavour.

Decoration:

• 1 Lemon zest only

Metric – US Customary

Instructions

Start by making the lemon sponge cakes:

• Preheat the oven to 160°C fan / 180°C conventional. Grease and line two 8-inch round cake tins with baking paper. See section on using cake strips in the main blog post above.
• Beat the margarine (or butter) and caster sugar together until light and fluffy.
  350 grams Margarine or unsalted butter, 350 grams White caster sugar
• Beat in the eggs one at a time. TIP: Add a spoonful of the flour with each egg to stop the mixture from curdling.
  4 large Eggs
• Add the flour, baking powder and milk. Fold to combine.
  350 grams Self-raising flour, 1 teaspoon Baking powder, 3 tablespoons Milk
• Add the lemon zest and juice. Fold to make a smooth cake mixture.
  1 Lemon
  
• Divide evenly between the cake tins and level out the top.
  
• Bake on the middle shelf of your oven for 35-45 minutes* (see notes below) until risen, golden and the sponge springs back when pressed in the middle. Leave to cool completely in the baking tins.
  

Now make the Swiss meringue buttercream:

• Separate your eggs into whites and yolks* (see notes below). Pour the egg whites into the bowl of your stand mixer. Add the sugar and whisk to combine.
  5 large Eggs, 340 grams Granulated sugar
• Fit the bowl over a small saucepan filled with an inch of simmering water, set over medium heat. Do not let the bottom of the bowl touch the water. Whisk constantly until the sugar is fully dissolved, the mixture is white and foamy on top and it doesn't feel grainy when rubbed between your thumb and finger. This will take roughly 5-10 minutes.
  
• Attach the bowl to your stand mixer fitted with the whisk attachment. Whisk on medium-high speed until the meringue reaches stiff glossy peaks that stand tall and don’t curl over (roughly 10-15 minutes). The meringue and bottom of the mixing bowl should no longer feel warm to touch. If they do, pop the bowl in the fridge for 10 minutes to cool down. 
  
• Scoop out roughly half of the meringue into a piping bag fitted with a large star nozzle (you'll use this to pipe the toasted meringue swirls on top of your cake). Set the piping bag aside for now.
• Swap the whisk for the paddle attachment and set the mixer to medium-low speed. Cut the butter into chunks and add it bit by bit, making sure it's fully incorporated before adding the next one.
  150 grams Unsalted butter
• Now set the mixer to a slow speed and add the vanilla and salt. The Swiss meringue buttercream should be thick, creamy, and silky smooth. *Not looking quite right? Check out the notes section below for troubleshooting tips*.
  1 teaspoon Vanilla extract, ¼ teaspoon Salt
  

Assemble the lemon meringue cake:

• If the cakes have domed on top, level them off with a sharp knife. You want to get them as flat and level as possible.
• Place one sponge layer on a cake stand or plate and spread a layer of Swiss meringue buttercream on top. Pipe two rings of buttercream around the outside, then fill the middle with the lemon curd.
  4 tbsp Lemon curd
  
• Flip the second cake layer upside down and place it on top. Spread another layer of buttercream on top and zest the lemon.
  1 Lemon
• Finish by piping swirls of meringue around the outside. Use a blowtorch to lightly toast and brown them (be careful not to melt the buttercream!). Serve and enjoy!

RECIPE NOTES

*BAKING TIME*
If your oven tends to cook quickly/runs hot, check on the cake after 35 minutes. If you’re oven cooks slowly/runs cool, bake for 40-45 minutes. If using cake strips, your cake will take longer than normal to bake. I’d suggest somewhere around 45 minutes.

*EGG WHITES*
The egg whites must contain no yolks, as this can prevent the meringue from whisking to stiff peaks. When separating the whites from the yolks, it’s best to separate one egg at a time into a spare bowl. Then pour each egg white into the bowl of your stand mixer, and repeat for the remaining eggs. 

*SWISS MERINGUE BUTTERCREAM TROUBLESHOOTING*

Looking thin and soupy? Place the bowl in the fridge for 30 minutes to chill and firm up the butter. Then return to the mixer and beat slowly until thick. Repeat if needed.

Looking split and curdled? Place the bowl back over a pan of simmering water on low heat. Leave for a few minutes until the buttercream slightly melts around the outside. Return the bowl to the mixer and beat slowly until smooth and creamy. Repeat if needed.
