This Lemon Celebration Cake combines a light, citrus-infused sponge with a warm lemon drizzle, pockets of tangy lemon curd, and a beautifully whipped lemon buttercream frosting. With a 15-minute prep time and 35 minutes in the oven, it’s a foolproof, elegant crowd-pleaser perfect for any summer gathering or tea party.

Notes from The Patisserie

After posting the recipe for my Victoria sponge celebration cake, I figured it would be so much fun if I experimented on this and produced different flavours. When I asked on my Facebook and Instagram page recently if anyone had any suggestions, and to my joy many of you suggested a lemon celebration cake!

I feel a lemon flavour for a celebration cake is always a safe flavour as (usually) everyone likes lemon. I also find its perfect for after dinner as the zesty and fresh lemon cleanses your mouth leaving a refreshing aftertaste.

The secret to a truly moist citrus sponge is all in the timing of that drizzle. Pouring a warm liquid sugar mixture over the cake layers the second they come out of the oven ensures it sinks deep into the centre. If you wait until the cake cools, the surface seals up, and the drizzle will simply pool on top, leaving you with a sticky exterior and a dry middle.

While a massive multi-layered cake looks stunning, a reliable two-layer sandwich cake is much easier to bake, handle, and slice. It allows you to simply slather a thick, luxurious layer of buttercream and tangy lemon curd right in the centre without worrying about the cake shifting, collapsing, or leaning on display. For the perfect sponge I use:

  • Butter – unsalted butter at room temperature or baking spread works perfectly
  • Sugar – I use caster sugar here to create the smooth creamy texture with the butter
  • Eggs – as usual I am using medium eggs
  • Flour – self raising flour provides the perfect lift to your sponge
  • Zest of lemons – natural lemon zest provides that non-synthetic flavouring along with the juice
  • Lemon juice – enhances the flavour even more

How to keep your lemon buttercream from splitting

Adding real fruit juice to a fat-based buttercream can be intimidating, and many comments are souly around the fact that their buttercream is splitting. But, with a little patience this will prove to be the saving method for perfect buttercream.

Always start by whipping your real block butter completely on its own for a few minutes until it is perfectly smooth and pale. Sifting and adding your icing sugar slowly builds a sturdy structure that can easily lock in the liquid lemon juice at the end without curdling or weeping. Take your time.

FAQs

Can I use shop-bought lemon curd instead of making my own?

Absolutely! While homemade lemon curd is simple to whip up, a high-quality, luxury shop-bought lemon curd works beautifully and saves you extra prep time.

What can I use if I run out of fresh lemons for the decoration?

If you don’t have enough fresh lemon juice left to finish the buttercream frosting, you can easily substitute it with 2 teaspoons of high-quality lemon extract instead.

Can I turn this two-layer cake into a dramatic four-layer cake?

Yes, easily! Because these 8-inch sponge layers bake up thick and sturdy, you can carefully slice each cooled sponge horizontally in half using a long serrated bread knife to create a gorgeous, towering four-layer showstopper.

Why do we use caster sugar instead of icing sugar for the drizzle?

Caster sugar has a fine grain that dissolves perfectly into warm lemon juice without making it overly thick or gummy, allowing the liquid to run deeply into the baked cake crumbs.

  • 75 ml lemon juice

Drizzle

  • 75 ml lemon juice

Decoration

  • 2-3 tbsp lemon curd
  • 200 g unsalted butter (room temperature)
  • 400 g icing sugar
  • 2 tbsp lemon juice
  • spare lemon curd

Instructions

Cake

  • Grease & line two 8"/20cm deep cake tins and preheat your oven to 180ºc/160ºc fan.
  • Beat together the unsalted butter & caster sugar until smooth – this will take a couples of minutes! 
  • Once combined add the self raising flour, eggs, lemon zest and lemon juice and beat until combined – try not to over beat!
  •  Pour the mixture evenly into the two tins and bake in the oven for 35-40 minutes or until a skewer comes out clean.

Drizzle

  • Towards the end of baking – in a bowl, mix together your 75ml lemon juice and 75g caster sugar together.
  • Once the cake is baked, drizzle this over the cakes, whilst still in the tin. Let the cakes cool fully.

Decoration

  • Beat the unsalted butter for a couple of minutes using the whisk attachment with a stand mixer – doing this will make it nice and smooth!
  • Once smooth, start gradually adding the icing sugar until it’s all fully mixed in.
  • Add the lemon juice, and beat for about 5 minutes on a medium-high speed until super light and whipped.
  • Pipe some buttercream in a circle round the edge of the top of your first sponge, and then add the lemon curd into the middle.
  • Place the other cake on top, and pipe on the rest of the buttercream however you wish. 
  • Drizzle on some spare lemon curd, and add some sprinkles and enjoy!

Storage and freezing

Because of the incredible moisture from the fresh lemon drizzle, this celebration cake stays remarkably fresh and soft. Store it in an airtight container at room temperature for up to 3 to 4 days. Avoid putting it in the fridge, as the cold temperature will firm up the butter in the sponges and make them taste dry.

To freeze ahead, wrap the un-iced, fully cooled and drizzled sponge layers tightly in a double layer of cling film and store them in the freezer for up to 3 months. Simply defrost them on your counter overnight before whipping up fresh buttercream and assembling.

    Love this recipe but could I swap out the normal drizzle and use limoncello instead?

    Hiya I am looking to make this for my dad’s Birthday 🙂 I only have a 9inch cake tin would this be too big ? I don’t want the sponge to come out to thin or would I have to adapt the recipe? Thank you
