Yogurt Banana Cake

Baked this yogurt banana cake last night.
Hubby bought some bananas from the supermarket yesterday. But he found that they are way too ripe. So he asked me to bake something out of them. Searched the web (I don't have any cookbooks, I use the internet to search for recipes most of the time). So, I choose this yogurt banana cake from Taste.com.au.I omitted the frosting but decorated the cake with some chopped walnuts.

Yogurt banana cake

Ingredients:
125g butter or margarine
100g caster sugar
2 eggs
2 very ripe bananas, mashed
200g plain yoghurt
200g (1 1/3 cups) plain flour
1 1/2 tsp baking powder
About a handful of chopped walnuts

Method:
1. Preheat oven to 180°C. Grease a loaf pan with the melted butter or margarine.
2. Beat butter or margarine and sugar in a bowl with electric beaters until pale and creamy. Add eggs one at time beating well after each addition. Fold in the mashed bananas and yoghurt with a large metal spoon.
3. Sift together the flour and baking powder and then fold gently into the yoghurt mixture until just combined. Spoon mixture into prepared pan and bake in preheated oven for 40-50 minutes or until a skewer inserted into the center of the cake comes out clean. Remove from oven. Stand for 5-10 minutes then remove cake from pan and place it on a wire rack to cool.
