Banana Bread

This is my mum's recipe, which I have been meaning to get for a while because I am suddenly very into Banana Bread, and of course I love my mum's. But, sorry mum, I fully intend on trying out a few different ones - sort of a 'Banana Bread-Off' if you will.
You will also notice that this bread is made with olive oil rather than butter, so you can kid yourself a bit that its healthy - and then put butter on the top! But I really love this bread with cream cheese.

½ cup olive oil
1 cup sugar
2 eggs, beaten
2-5 very ripe bananas, mashed (you can basically put in as many as you want)
2 cups flour
1 tsp baking soda
½ tsp baking powder
½ tsp salt
3 tbs milk
½ tsp vanilla
½-1 cup chopped nuts, either pecans or walnuts

Beat together the oil and sugar. Add the eggs and mashed banana and beat a bit more.
Sift together the flour, baking soda, baking powder and salt, and add to the banana mix. Add the milk and vanilla too and mix it all together. Mix in the nuts, and pour the batter into a greased and floured loaf tin.
Bake at 175˚C for about 1 hour, or until cooked through.
