Top Gluten-Free Baking Tip

I’m going to start out strong by giving away the ultimate gluten-free baking secret. Yup, this gluten-free Lemon Curd Cake utilises my favourite tip for achieving an easy drop jaw yummy gluten-free cake.

Plain Gluten-Free Flour + Ground Almonds

This flour combo means you don’t get the dry, slightly gritty or crumbly drawbacks that affect some gluten-free offerings. There is also no gummy mouthfeel. It’s gluten-freeness will be totally undetectable.

The best thing is you can use pretty much any gluten-free flour blend from the supermarket. I use Doves Farm as that is the most widely available in the UK and is xanthan gum free which suits my intolerances. However, this recipe will work with Bob’s Red Mill or even a home DIY blend.

What makes this Lemon Curd Cake so brilliant?

  • The lemon sponges are a doddle to make with no complicated method. They use shop bought plain gluten-free flour and ground almonds.
  • No xanthan gum. My cakes never include xanthan gum and here’s why.
  • Homemade Easy Lemon Curd. So bright, zesty and full of flavour. It’s sandwiched between the cake layers and used copiously in the buttercream.
  • Swiss Meringue Buttercream. This incredibly buttery cake frosting is a perfect contrast to the light zingy lemon flavours. It’s easier to make than you think and all the tips and tricks are below.

Baker’s Tips

  • Make sure to add the whole eggs one at a time. It makes the sponge lighter. If the eggs are dumped in all at once you risk losing the air you just whipped into the butter and sugar.
  • I use Doves Farm Gluten-Free Plain Flour. It’s the most widely available in the UK. However, any gluten-free flour blend will be fine here.
  • You don’t want the almond taste to be too strong or compete with the lemon. The almonds are used to give the cake texture and bind it together so ready ground almonds from the supermarket are perfect. If you grind them yourself the almond flavour will be more pronounced.
  • You can use shop bought lemon curd which is lovely if you buy a good brand. However, why not take it the extra mile and make this homemade Easy Lemon Curd. You won’t be disappointed.

It’s all very well having deliciously lemony sponge with perfect texture and taste but we want to make this cake really special. So let’s take it up a notch and make a Lemon Curd Swiss Meringue Buttercream to really impress.

If you haven’t made Swiss Meringue Buttercream before you might find the equipment needed (sugar thermometer, double boiler and stand mixer) a bit intimidating.

Plus the number of steps required are also a couple more than your regular icing sugar + butter method.

Please though don’t let it put you off. Try it once and I guarantee it’s pretty hard to mess up as long as you follow my troubleshooting tips below. You’ll also find it hard to go back to icing sugar, the taste and texture is pretty unbeatable.

How do you make Lemon Curd Swiss Meringue Buttercream?

  1. Heat the egg whites and sugar in a bain marie or double boiler, whisking all the time.egg whites and sugar in a metal bowl
  2. When the sugar has completely melted and the temperature reached 71°C then remove from the heat and immediately pour into a stand mixer.
  3. Whisk on a medium setting for about 10 minutes until a glossy meringue has formed and the temperature has lowered to about 32°C.close up of whipped swiss meringue in a bowl
  4. Change the whisk attachment to a paddle beater and beat on low adding the butter one cube at a time.swiss meringue buttercream in a bowl
  5. Once all the butter has been added and the buttercream looks beautifully smooth then add the lemon curd and salt and mix in until thoroughly combined.close up of lemon curd swiss meringue buttercream in a bowl

Swiss Meringue Buttercream Tips

  • I recommend buying Two Chicks Liquid Egg Whites as it saves wasting the yolks or finding a use for them. You will only need about half the carton but you can freeze the other half for your next foray into SMB.
  • The temperatures here are important. If you have made SMB a few times then you can intuit when the sugar has melted into the egg whites or when the meringue has cooled enough to add the butter. However for newbies a sugar thermometer is invaluable. The Thermopen is my favourite.
  • The butter must be at room temperature before you add it. Slightly soft to the touch but not melty.
  • If your butter is too cold then just keep on mixing the buttercream once it’s all added, the butter will soon warm and melt into the buttercream. If that doesn’t work then warm slightly over a bowl of boiling water. Once the edges of the buttercream start to soften then start whipping again off the heat.
  • If your butter is too warm place in the fridge for 15 minutes to chill then try re-whipping it.
  • As you are adding the butter your buttercream will look a bit curdled. This is absolutely normal. Keep on mixing the buttercream and don’t lose faith, it will always come together in the end.
  • If your buttercream does not come together and looks too soupy that means your butter was too warm – see above on how to fix.

Can I freeze Lemon Curd Cake?

You certainly can. I recommend chilling the whole finished cake first in the fridge so that the buttercream gets quite firm. Wrap well in cling film then tin foil and freeze for up to 2 months. Remove from the freezer and allow to defrost thoroughly before removing the tin foil and cling film.

Variations on Lemon Curd Cake

  • You can replace the lemon curd with any curd of your choosing. Passion Fruit Curd Cake? Raspberry Curd Cake?
  • If the Swiss Meringue Buttercream still seems intimidating to you then why not swap it out for a simple cream cheese buttercream which would be amazing. (Try the buttercream from this Carrot Cake recipe and add in a couple of spoonfuls of lemon curd).

Lemon Curd Cake {gluten-free}

This Gluten-Free Lemon Curd Cake is a real homey cake with bright fresh citrus flavour. Homemade lemon curd is sandwiched between lemon and vanilla infused sponges which are covered with a cloudlike lemon curd swiss meringue buttercream.
Prep Time50 mins
Cook Time40 mins
Course: Cake
Cuisine: British
Servings: 16 generous slices
Calories: 681kcal

Ingredients

  • 320 g caster sugar
  • zest of 2 lemons
  • 240 g unsalted butter room temperature
  • 6 eggs medium
  • 2 teaspoons vanilla extract
  • 180 g gluten-free plain flour
  • 180 g ground almonds
  • teaspoons baking powder
  • ¾ teaspoon salt
  • 150 g lemon curd

Lemon Curd Buttercream:

  • 210 g egg whites about 7 medium egg whites
  • 350 g caster sugar
  • 490 g unsalted butter
  • 150 g lemon curd

Instructions

  • Pre-heat the oven to 180°C/160°C/gas mark 4 and line and grease 2 x 8 inch round cake tins.
  • Beat the sugar with the lemon zest and butter until light and fluffy.
  • Add the eggs one at a time, mixing well between additions.
  • Add the vanilla extract.
  • In a separate bowl whisk together the flour, almonds, baking powder and salt then beat into the rest of the ingredients.
  • Divide the cake batter between the two tins and bake for 30 minutes.
  • Remove from the oven. Allow the sponges to rest for 5 minutes before carefully removing from the tins and cool completely on wire racks.

Lemon Curd Swiss Meringue Buttercream

  • Heat the egg whites and sugar in a bain marie or double boiler, whisking constantly until the temperature has reached 71°C.
  • Remove from the heat and pour into a stand mixer with a whisk attachment. Whisk until the mixture forms stiff peaks and the temperature has reduced to about 32°C.
  • Change the attachment to a paddle attachment. On a low speed add the butter slowly cube by cube. When you have almost added all the butter the mixture will look curdled. Do not fret – this is supposed to happen and just means you are nearly done, just continue to add all the butter. Once the butter is totally incorporated the buttercream will miraculously become a smooth velvety consistency.
  • Add the lemon curd and salt and mix until thoroughly combined.

Assembly

  • Place one of the sponge layers on an 8 inch cake board and spread the lemon curd from the centre of the top of the sponge almost to the edges.
  • Place the second sponge layer on top and cover the top and the sides of the cake with the buttercream.

Notes

Eggs – I usually use medium eggs in my baking recipes. Add the whole eggs one at a time. It makes the sponge lighter. If the eggs are dumped in all at once you risk losing the air you just whipped into the butter and sugar.
Gluten-Free Flour - I used Doves Farm Gluten-Free Plain Flour. It’s the most widely available in the UK. However, any gluten-free flour blend will be fine here.
Ground Almonds – I don’t want the almond taste to be too pronounced here. The almonds are used to give the cake texture and bind it together so I use ready ground almonds from the supermarket. If you grind them yourself the almond flavour will be more pronounced.
Does your batter look curdled? After you mix in the eggs the batter seems to curdle. Don’t worry at all, there is a lot of fat in this cake from the butter and the eggs. As soon as you add the flour then the mixture comes together. Although it won’t appear smooth due to the ground almonds.
Homemade Lemon Curd - I really recommend you follow this recipe for an absolutely delicious Easy Lemon Curd but of course you can certainly use shop bought if you don’t have time.
Swiss Meringue Buttercream – for troubleshooting any problems which may arise making your buttercream see the content of this post for detailed advice. Remember, it’s very hard to break SMB, any problems can usually be fixed.
Store – This cake can be stored in the fridge for up to 3 days. Remove from the fridge for at least an hour to come to room temperature before serving.
Freeze – You can freeze the whole finished cake. Chill in the fridge to allow the buttercream to firm before wrapping well in cling film and tin foil. You can freeze for up to 2 months. Defrost completely before removing the cling film and tin foil.

Lemon Raspberry Cake {gluten-free}

This Gluten-Free Lemon Raspberry Cake is a wonderfully indulgent cake for a special occasion. The very lemony sponge is made from ground almonds and plain gluten-free flour so it is incredibly accessible for novice gluten-free bakers. Fresh raspberries are baked into the sponge but also fill the cake along with a lemony mascarpone cream.

If you are new to gluten-free baking or just want a break from any complicated recipes using a multitude of alternative flours or weird gums then this is the cake for you.

Wonder why I don’t like to bake with xanthan gum? Then read this.

What makes this cake so brilliant

  • Beautifully moist and light texture.
  • Bright tangy flavour from lemon zest and raspberries.
  • Extra special gentle hint of Limoncello.
  • Easy to make – no special gluten-free flours, just a regular supermarket blend.
  • No xanthan gum!!!
  • Creamy lemony mascarpone filling – so full of flavour.
  • Make ahead. This cake needs an overnight stay in the fridge right at the end of the process, making it perfect for advance baking.

Two secrets of gluten-free cakes

The sponges are incredibly light and moist since they use two of my favourite techniques for successful gluten-free baking.

Want to know what they are??

1. Ground Almonds

Ground almonds are the secret weapon of any gluten-free baker. They add fantastic moisture and texture to gluten-free cakes and bakes. If you find certain brands of gluten-free flour lead to dry and crumbly cakes then swap in half of the quantity with ground almonds. You’ll be thrilled at the difference this makes.

Baker’s Tip

But I don’t like the taste of almonds. No? Don’t worry about it. If you use supermarket ready ground almonds from a packet then you can barely, if at all, taste the almonds. These packets don’t do a great job of preserving flavour. All the right texture is still there though to produce a gorgeous sponge.

However, if you love the taste of almonds and want to make the most of the flavour then grind the almonds yourself at home. The fresher the grind the more flavour.

Baker’s Tip #2

If you are grinding the almonds yourself then add in a few tablespoons of the caster sugar into the food processor along with the almonds. The caster sugar will help the almonds break down more finely without releasing too much of the almond oils.

For more detailed info on making your own ground almonds and using nut flours in gluten-free baking in general then visit this post.

2. Egg Whites

For this Lemon Raspberry Cake we add in 2 extra egg whites along with the whole 5 eggs.

This adds air and lightness into the sponge.

Sometimes gluten-free cakes are accused of being too dense or heavy. By adding in some extra egg whites we are lifting the cake. It works well here as the creamy raspberry filling needs a lighter sponge.

Baker’s Tip

Adding in the egg whites does add more moisture into the cake so be careful that you don’t just add egg whites into your cakes willy nilly. Start with one egg white in a cake batter you find particular dense and take it from there.

How to make a cake more lemony

There is nothing more disappointing than a lemon cake which doesn’t taste of lemon. These are a few methods to add lemon flavour to a cake

  • Lemon zest and juice – These are the most obvious choices. Quite often you need a lot of juice though to really come through so I prefer lemon zest as too much juice messes around with the liquid ratio too much. In this Lemon Raspberry Cake we use the zest of 2 lemons in the sponge.
  • Lemon extract makes the most intense flavour as it is really distilled. If you go this route use a really good shop bought organic extract.
  • Lemon syrup or Limoncello (!) These are excellent flavour enhancers. In this recipe we use Limoncello to brush over the sponges fresh out of the oven which intensifies the flavour. We also use some Limoncello in the Lemon Mascarpone Cream but if you need an alcohol-free version then just substitute with homemade lemon syrup (see method in recipe card).

How to make Lemon Raspberry Cake

1. First whip the egg whites so they are stiff.

2. Beat the sugar with the lemon zest and butter.

3. Add the whole eggs one at a time then the vanilla.

8. Once cakes are cool, cut in half to create 4 cake layers.

9. Whip the double cream until thick but runny.
10. Add the mascarpone and Limoncello or lemon syrup.
11. Assemble the cake with sponge, then 1/3 cream then 1/3 fresh raspberries.
12. Smooth out the cream around the sides to create the naked look.
13. Wrap the cake in cling film and place in the fridge overnight.

14. Unwrap the cake, sprinkle over icing sugar and serve.

Baker’s Tips

  • Whisk the egg whites first. It saves washing up the food mixer. Egg whites require a good clean mixing bowl. So whisk them first, tip them into a bowl to set aside. Change the attachment on your mixer from a whisk to a paddle beater then start beating your sugar and butter right in the same mixing bowl, you don’t need to wash it out.
  • Make sure to add the whole eggs one at a time. It makes the sponge lighter. If the eggs are dumped in all at once you risk losing the air you just whipped into the butter and sugar.
  • By all means, if you can’t be bothered with Limoncello or lemon syrup then just add zest of a whole lemon. It won’t be as smooth but still delicious.
  • To cut the cakes in half I really recommend a cake leveller. These are also excellent for cutting the tops off of domed sponges.
  • Don’t skip the step of wrapping and resting the cake in the fridge before serving. This is so the raspberries have a chance to sink into the cream and the cake adheres together.

Slice of Lemon Raspberry Cake

How to store

The cake will keep up to 3 days wrapped up well in the fridge. Since the cake has fresh cream it should not be left out in the sun or a warm kitchen for any length of time.

Can I freeze Lemon Raspberry Cake?

You can’t freeze the whole finished cake. But you can freeze the initial two cake sponges once cooled. Double wrap well in cling film and tin foil. Remove from the fridge to defrost overnight. Then you can cut the cake halves and make the cream for assembling the cake.

Variations

  • Fruit – this cake is amazing with the raspberries but you can try any berry. Blackberries or blueberries are also particularly good. Or maybe a mixture?
  • Icing – I like this cake with a simple powdered icing sugar top but a raspberry drip, like in this Raspberry Pistachio Cake would look amazing!
  • Cream Cheese Buttercream – swap out the Lemon Mascarpone cream for a simple cream cheese buttercream. Use the recipe from this Carrot Cake.

  • Drop 75g of raspberries into each tin, smoothing the cake batter over the top.
  • Bake for 50 minutes or until an inserted toothpick comes out clean.
  • Remove the cakes from the oven, leave in their tins for 5 minutes before inserting them out onto cooling racks.

Notes

Gluten-Free Flour
  • I used Doves Farm 'Free From Gluten' Plain White Flour
Limoncello or Lemon Syrup
  • If you don’t want to include any alcohol in this cake then you can substitute the Limoncello with the Homemade Lemon Syrup outlined in the recipe above. If you are using the Limoncello then you don’t need the Lemon Syrup
Lemon Mascarpone Cream
  • Use a balloon whisk to whip the double cream and always whisk by hand for maximum control. The cream can be overwhipped in a matter of moments. The double cream will continue to be whipped when you are mixing with the mascarpone so if anything underwhip the double cream at first.
Assembly
  • Use a sharp knife or a special cake cutting tool to cut the cakes in half.
  • It’s important to wrap the cake up and leave to rest before serving. This is so the raspberries have a chance to sink into the cream and the cake adheres together.
Store
  • The cake will keep up to 3 days wrapped up well in the fridge. Since the cake has fresh cream it should not be left out in the sun or a warm kitchen for any length of time.
Freeze
  • You can freeze the initial two cake sponges once cooled. Double wrap well in cling film and tin foil. Remove from the fridge to defrost overnight. Then you can cut the cake halves and make the cream for assembling the cake.
