Chocolate banana cake

Had a few really ripe bananas to use up so decided to make a banana cake. Then I fancied something chocolate, so changed the recipe into a chocolate version. I'm very pleased with the result. It's a very moist cake.

150g butter or margarine
150g light brown sugar
300g plain flour
2 tspn baking powder
2 eggs, beaten
4 tbspns cocoa powder
50g dark chocolate broken up [or chocolate chips]
100 ml vegetable oil

Preheat oven 180C/gas4

Grease a 900g loaf tin.

Beat the eggs and sugar together.
Mash up the bananas and add to the mixture.
Beat in the eggs.
Mix the flour, baking powder, cocoa and chocolate together, then add these to the mixture.
Lastly add the vegetable oil, and give it all a good mix.

Spoon into the tin and bake for about 45 mins.
I found that because of the lumps of chocolate, the centre was quite soft. I checked to see if it was cooked in several other places.
Leave it to cool for 10 mins in the tin, and then turn onto a wire rack.

You can see the melted chocolate in the centre of the photo.
