Chocolate Marble Chiffon

I've no idea what cakes I would like to bake, my mind is just hanging and running out of idea. Other than making ice cream, I feel myself have no mood to do anything (may be the weather is too hot). So, I decided to do something simple rather than complicated baking.

This the simple marble chiffon cake I've baked which is nothing special that had filled my mood as the texture is excellent. The bad thing is the surface got a tunnel which I've no idea why. How nice if it's a smooth surface and this could be the perfect baked chiffon.

This reminded me life is not perfect, it's the matter of how we value and appreciate everything we have at the moment.

Ingredients for 21cm chiffon pan:

Egg white mixture:
180g egg whites
90g caster sugar
10g corn flour

Egg yolk mixtures:
70g egg yolks
60g water
60g vegetable oil
70g + 10g plain flour
20g caster sugar
8g cocoa powder

1. Mix all the egg yolks, water, oil together until well combined. Add in the 70g of flour and the 20g of sugar, mix everything well combine and no lumps left.
2. Measure the egg yolk mixture and divide it into equal quantities of two portions in separate mixing bowl.
3. Mix 10g of the flour into a bowl of egg yolk mixture and mix 8g of cocoa powder into another bowl of egg yolk mixture.
4. Beat the egg whites in a clean large bowl until peak foam. Gradually add in sugar, one tablespoon at a time. Then finally add in corn flour. Make sure the corn flour mix well in the egg mixture. The egg whites mixture should be peak foam, smooth and shiny. Gently fold in half of the egg whites mixture into the cocoa egg yolks mixture and plain mixture accordingly until well combine. (Note: This stage took some times and patient and practice. Make sure all the egg whites mixture well combine with the egg yolks mixture without breaking the egg whites. Little egg whites left will cause a big hole in the cake during baking. And, over mixing will cause it hardly rise during the baking.)
5. Pour the well mix mixture into a 21cm chiffon cake tin and bake at a 170'C preheated oven for 50 - 55 minutes. After baked, let the baked cake turn upside down for cooling before unmold it. Enjoy this supper soft and fluffy chiffon cake!
