I can’t believe I have not tried baking sponge cake before. I did not realise it was just made of 3 basic recipes: egg, flour and sugar. No baking powder!
I was looking for a basic low cost cake recipe to frost to experiment with frosting and I came across this recipe.
1. DIY cake flour
I don’t store cake flour or self raising flour and make my own.
DIY Cake flour formula
Cake flour= 1 cup AP flour – 2 tbs AP flour + 2 tbs of cornstarch
Cup and tbs to gram conversion for AP flour
1 cup AP flour= 120g AP flour
1 tbs AP flour= 8g AP flour
I need 90g of cake flour= 78g AP flour +12g cornstarch
I stirred and sifted it 5-6 times.
2. Beat sugar and eggs
It took me 8 minutes with my hand mixer and tilting the mixing bowl.
It started off foamy and then became creamy and light yellow
I used it and made a ‘ribbon or 8 pattern’ and it stayed
3. Sift cake flour and fold
I did it in 7-9 batches, bit by bit.
And poured it into a buttered and floured circle cake tin.
4. Bake
I baked it at 165C for 32 mins but will make some changes in the future.
Troubleshooting (reference)
Peaked center: oven temperature was too hot.
Shrinked at the edge: overbaked. It was all good after 25 minutes. At the 32 minute mark, it shrunk.
Next time it will be 30 mins bake time and lower temperature to 155C
