I'm cooking this todayRecipe's preparation
Preheat oven to 180C
Line cake tins with baking paper. I like to use two 22cm springform tins or three 18cm springform tins, then I can easily fill with jam or curd.
weigh sugar into clean, dry TM bowl
mill at speeed 9 for 1 minute
scrape down sides of bowl and set aside
Weigh cornflour into a small bowl, add bicarb and set aside
place butterfly in TM bowl
add egg whites and cream of tartar
set timer for 10 mins, 37C, speed 3.5
After 4 minutes, add the icing sugar in small, regular spoonfuls over the next 3 minutes
Allow another minute for sugar to fully dissolve
Add egg yolks one at a time until just combined
Reduce the speed to soft speed, then add cornflour a spoonful at a time until all combined. Gran used to do this with a fork to ensure the air didn't get knocked out of the meringue, but I find this method just as good.
Stop as soon as mixture is combined. Don;t over mix.
Using a spatula, pour and scrape into prepared tins
For 22cm tins, cook for 25 mins; for 18cm tins, cook for 22 mins
You will probably need to stop the machine from time to time and scrape down the sides especially when beating the meringue as air pockets form at the bottom, and when mixing in tbe cornflour to ensure it is fully combined.
Tip
Note: If you use a gluten free cornflour this cake is gluten free. I use Woolies Macro Organic cornflour and have written to woolies to confirm it is gluten free.

I tried this recipe twice and it failed on both occassions! The first time I think I got my icing sugar and cornflour mixed up,so tried it again and it was flat and brown/burnt looking. This is only my first Thermomix Cake attempt and was reading off my computer - I didn't see the note about the need to scrape the sides, so this may have contributed to the failure. Next time I will print a copy off.
I tried this, halving the quantities as there are just the two of us. It was delicious but flopped a bit in the centre, probably because the batter was a bit shallower in my pans than it would have been if I'd made the full quantity. Also, when I make a sponge in the traditional manner, I sift the dry ingredients onto the batter in the last step, which means one would need less folding in, and that way maybe keep the air in. Definitely worth trying again, but making the full quantity and trying the sifting.
Well, I'm embarrassed to say, the sponge is not "fool-proof" mine flopped. Both of then sunk in the middle and had the consistency of chewy meringu. However! I made a batch of lemon curd and turned them into a double decker "lemon flan" with whipped cream so that my chef husband wouldn't laugh at me for failing the fool proof sponge lol
i don't know why this happened, I followed the recipe to a T.......
Love this recipe, a simple and real fool proof cake! Can the sponge be frozen and successfully defrosted? And what kind of jam do you recommend to serve it with?
Wow, what a great recipe, thank you! My mother in law made a 'failproof' sponge, though she used custard powder and cornflour. I wonder if this is a similar recipe? She also used to mix the flour in with a fork. She was an amazing cook, I wonder what she would have thought of the thermomix!? I followed the recipe to the tee, and it worked really well - light and airy. I used two cake tins, filled with jam and topped with cream and berries as you have in that gorgeous picture. Thanks again
