My Mom's Pandan Chiffon Cake

It was my mother-in-law's birthday yesterday and she requested for her favourite Pandan Chiffon Cake. This is my mom's recipe which was passed down to her by her Godmother. My mother-in-law was quite happy with it and the cake was almost half gone by the end of yesterday.

Here is the recipe:

1 tsp green colouring

Ingredient C:

1 tsp baking powder

Method:
1. Beat A till white, fluffy and stiff.
2. Mix B in another bowl
3. Shift C into B and mix well.
4. When A is fluffy and stiff, pour the mixture in step 3 into A and mix well.
5. Pour into 23cm chiffon cake tin
6. Bake at 160 - 170 degrees for 1hr.
7. Turn the cake upside down and wait till it cools totally before cutting.
