250g salted butter
1 1/2 cups castor sugar (I will reduce the sugar depending on what type of banana that I used and how ripe the bananas are, normally 180g to 200g)
1 tsp vanilla essence
4 tbsp milk
1 1/2 cups mashed banana (about 3 del monte bananas, sometimes I put more)
2 cups plain flour (220g sift together with 1 tsp bicarbonate of soda and 1 tsp baking powder)
Walnut for decor
1. Cream butter and sugar in a mixing bowl.
2. Add in eggs, vanilla essence and milk and mix well.
3. Add mashed banana into the mixture and mix well.
4. Finally add in sifted flour and mix well and pour into a cake tin. Sprinkle walnut on top.
5. Bake in preheated oven at 160 deg C for 1 hour or until a skewer inserted into the centre of the cake comes out clean. If the top layer turns brown after 15 minutes, cover it with a piece of aluminium foil.
6. Cool cakes in the pan then remove. Use a sharp knife to slice and serve
