Sponge Cake top with Jelly

I'm supposed to make a three-layer jelly cake,but I ended  out making this one.For days,I I kept thinking of making a sponge cake at the bottom and two layers of jelly in the middle and top but I don't know why in the end I made only a sponge cake top with a thin piece of jelly only.Sigh!
(any brand sponge cake mix will do, just follow the box instructions)

Recipe:
500g ready-mix Soon Huat moh sponge flour mix(before baking,take half the cake mixture only)
7 eggs(at room temperature)
100g water

Using an electric mixer,mix together the above ingredients and beat at highest speed  for 45 minutes until frothy.Bake in the oven at 180ºC until done.Cool the cake.

Bake the rest of the cake mixture.(I make 2 set to give 1 set to my relative)

To make the jelly:
A.500ml evaporated milk
    100g sugar
    1/4 tsp salt
    1tablespoon jelly powder

B.200ml water
    2 pandan leaves,knotted
    50g Hoen Kwee green pea flour
    1 teaspoon pandan paste

Method:
1.Boil ingredients(A) till jelly powder is sissolved.
2.Add in ingredients(B).Discard the pandan leaves.
3.Put the green pandan paste in and stir until well- mix.Quickly pour half the jelly on top of the
   sponge cake.Let it cool and refrigerate.

This is how I made my Jelly Sponge Cake.The three layers will have to wait someday when I am free again.
