4-Layers Banana Custard Cake

There was a ripe banana sitting on my kitchen table, and no one was going to eat it from the looks of it. Why waste the lovely sweet ripe banana? So, I have decided to make a 4-layers banana custard cake. The decoration was a bit off since it was an impromptu decision. Please bear with the 'lack-of-sense-of-decorative-mind' of mine. >.<.

Banana Custard Cream
(adapted from Ochikeron)
Ingredients:
120g banana (around 120g would be okay)
1 egg
30g sugar
170g milk
4 tbsp corn starch

Steps:
1. Heat the sauce pan at medium high.
2. Beat egg, sugar, milk, corn starch, and mashed banana till combined. Sieve the mixture to get rid of the lumps.
3. Pour into a saucepan, and stir the mixture till thicken on low heat.
4. Cool in fridge completely.
5. Spread the cooled custard cream on top of each layer of the cake, except for the top cake. Put the remaining custard into a piping bag, and pipe your desired decoration.

This cake has a very strong custard flavor, very yummy. I have never eaten Tokyo banana before, so I could not make the comparison. But, this cake is lovely enough.
