Zebra Sponge Cake

I came across a zebra cake the other day and I must say that I was fascinated by the beautiful stripes of the zebra cake. Since I have some cake flour left, I went ahead to bake this zebra sponge cake instead of the usual zebra butter cake.  Hb tasted and gave his thumb up but he did mention that it could be sweeter. :P

Ingredients:

5 eggs
250g cake flour
50g ice water
50g corn or veg oil

Cocoa mixture
2 tsp cocoa powder
1 tsp chocolate emulco

Method:

1. Pre-heat oven at 170c.
2. Put all ingredients (except oil) into a mixing bowl and whisk at high speed for about 10 mins till the mixture is thick and smooth.
3. Add the oil and whisk at low speed till well mixed.
4. Divide the batter into 2 equal portion and fold in cocoa powder & chocolate emulco into one of the portion
5. Using a tablespoon, scoop 2 tbsp of plain batter into the centre of the cake pan. Then scoop 2 tbsp of chocolate batter onto the plain batter in the cake pan, you will need to reduce the scoop to 1 tbsp or lesser when you reach the end so that the circle pattern will get smaller.
6. Repeat until you have finished all the batter.
7. Bake at 170c for 25 – 30 mins
