Banana cake

I baked again! This time it's a banana cake with butter frosting. I still don't know how to do the piping so it looks a bit messed up :) Anyway, here's the recipe:

Cake:

125g butter

1/2 cup caster sugar

2 eggs

1 tsp vanilla essence

1 1/2 cups mashed ripe bananas (about 4 medium)

1 tsp baking soda

1/2 cup milk

2 cups self raising flour

Butter frosting:

125g butter

3/4 cup icing sugar

1 tbsp lemon juice

1. Preheat oven to moderate 180C. Brush 20 cm round cake tin with oil or melted butter, line base with baking paper. Using electric beaters, beat butter and sugar in small mixing bowl until light and creamy. Add eggs gradually, beating thouroughly after each addition. Add essence and mashed banana, beat until combined.
2. Transfer mixture to a large mixing bowl. Dissolve soda in milk. Using a metal spoon, fold in sifted flour alternately with milk. Stir until all ingredients are just combined and the mixture is smooth. Spoon into prepared tin; smooth the surface. Bake for 1 hour or until a skewer comes out clean when inserted into center of cake.
3. Leave cake in tin for 10 minutes before turning onto a wire rack.
4. To make Frosting: Using electric beaters, beat butter, icing sugar and lemon juice until smooth and creamy. Spread onto cooled cake.

Tip: Very ripe bananas are best for this recipe as they have the most developed flavor.
