I must say that I’m feeling quite chuffed about finally perfecting this recipe. This cake is extremely light and airy in texture, even the next day. The ginger flavour is not overpowering and the hint of chocolate from the cocoa powder compliments this cake wonderfully. This is a ‘foam style’ of cake because it does not contain any butter or oil, as it uses only whipped whole eggs.
This recipe has been in development since early January this year! I’ve made this cake 8 times and have learnt valuable lessons about what not to do for next time. The first time I made it I used too much corn starch. Although it looked great, it was too dry and it squeaked as you were chewing it. Although it was edible, it really wasn’t that great.
Over the next few weeks I was literally making this cake once a week, tweaking the flour ratios slightly as I went. The cake kept sinking in places and unattractively wrinkling on cooling. I also think the boys were a little over it by the 5th week, so I put the recipe away for a while, as I was getting frustrated with it too.
When I did come back to it, I decided to try a completely different flour ratio all together. I was much happier with the outcome, as these flours produced a much lighter texture. However, it still wrinkled a little on cooling. I knew I was so close to perfecting this recipe, that I kept making it (what my boys have to endure at times). So after another couple of tweaks with the flour ratios, I finally had success!! Our eldest son Matthew, who has a fine tuned radar for any rice flour aftertaste, even said he was suitably impressed with this cake.
The eggs have to be at room temperature.
For accurate cup measurements, I sift the potato starch and icing sugar before measuring, so that there are no lumps/clumps. All cup measurements are firmly packed.
It is very important to sift the dry ingredients several times, this will result in a lighter sponge, do not skip this step.
I have a fast oven, so my cakes were cooked by the 18-minute mark, you don’t want to over-cook them because they will dry out.
144g (5.1 ounces or ¾ cup) golden/raw caster sugar or super-fine sugar
4 large eggs, at room temperature
33g (1.2 ounces or 3 tablespoons) potato starch
28g (1.0 ounces or 4 tablespoons) corn starch
27g (1.0 ounce or 3 tablespoons) brown rice flour
24g (0.8 ounces or 3 tablespoons) sweet rice flour
9g (0.3 ounces or 1 tablespoon) sorghum flour
8g (0.3 ounces or 1 tablespoon) tapioca starch
6g (0.2 ounces or 1 tablespoon) ground ginger
5g (0.2 ounces or 1 tablespoon) cocoa powder
1 teaspoon (5ml) cream of tartar
½ teaspoon (2.5ml) bicarbonate of soda (baking soda)
½ teaspoon (2.5ml) ground cinnamon
¼ teaspoon (1.25ml) xanthan gum
Jam & Mock Cream Filling
5 tablespoons ginger marmalade (I use this brand)
135g (4.8 ounces or 1 cup minus 1 tablespoon) pure icing sugar, sifted
112g (4.0 ounces or ½ cup) gluten and dairy free butter
2 tablespoons (30ml) cold water, from the tap is fine
1¼ teaspoons pure vanilla extract
Preheat the oven to 160C and grease two 20cm cake tins and then line the bases with baking paper or parchment and lightly brush with gluten and dairy free butter.
Using a stand mixer, beat the sugar and eggs on a low speed to combine and then turn the speed up to high, before continuing to beat for approximately 8-9 minutes until the mixture is thick and creamy.
Meanwhile, sift all the dry ingredients together 4 times, as this will result in a lighter sponge. Gently fold the dry ingredients into the egg mixture, until well combined.
Pour the cake mixture evenly into the prepared tins, place the tins in the same oven shelf and bake for approximately 18-20 minutes, or until just springy when lightly touched in the middle and shrinking slightly from the sides of the tin. Use a knife to loosen the cake from the edge, then turn the cake out onto a large plate, carefully remove the baking paper/parchment. Then invert onto a cooling rack lined with baking paper or parchment, as this will stop you cake from sticking to it as it cools.
To make the mock cream, add the icing sugar and butter to a stand mixer using a low speed to combine, scraping down the sides when necessary. Once combined, turn the speed up to medium-high and continue beating for about 3 minutes, until it is pale and fluffy.
Add 1 tablespoon of water and continue beating on medium until combined, scraping down the sides when necessary,
before adding the other tablespoon. Continue beating until thoroughly mixed through and then beat in the vanilla.
Once the vanilla is fully incorporated, turn the speed up to high. The mixture should be very fluffy, as to resemble a whipped cream texture.
To assemble the cake, transfer one of the sponges to a serving plate and spread a layer of ginger marmalade over one cake
and then spread over the cream. Place the other cake on top and liberally dust over icing sugar using a fine sieve.
