Nilupak is my favorite after school snack in the 80's where bananas were abundant at our farm, my Nana (mother) always prepare this for us and she made a very good one. 

Ingredients:
10 pieces unripe bananas (cooked and peeled)
3/4 cup margarine
1 cup sugar

Procedure:
1. Put the bananas in a mortar and pestle then pound it, when bananas are broken into bits add the sugar and margarine then continue pounding until smooth and sticky.
2. Serve right away or by using the lid of a jar you can form it to be more presentable and top it with grated coconut. Enjoy.
