Banana sponge cake (without baking soda)

Thanks to Hooi Thiam for this recipe. Now, I don't need to use any self-rising flour or baking soda in baking my cake. But it took me quite some time practising until I get my cake to rise.

Pictures show process (top left to right)




Ingredient A:
3 egg yolk
9 tablespoon of flour
1 and 1/2 tablespoon of sugar
3 small bananas
55ml water
35ml vegetable oil

Ingredient B:
3 egg white
3 tablespoon sugar

1) Put bananas to blend with the water.

2) Beat the egg yolk with the sugar till they blended well.

3) Add in the rest of the ingredients in A and mix well.

4) Pic. 3 shows egg white with sugar.

5) Beat the egg white with sugar till it turns fluffy and foamy as shown in pic. 4. When you lift up the whisk, the mixture will drool down slowly and form a circle.

6) Pour mixture B into mixture A. Blend well.

7) Pour into the sponge cake baking pan.

8) Put to bake in preheated oven at 150 Celsius for 35 minutes.

9) When cake is done, turn it up side down as shown in pic. 8.

Note: A successful sponge cake is, of course, SPONGY! Wow! I'm so proud of myself. =)
To be frank, even breaking the eggs are tough for me because I just can't get it right separating the whites from the yolks!
