Banana bread

I've been in need of different breakfasts recently, and unusually for me fancied some banana bread, which it occurred to me would do the trick. It is also easy to take a slice into work if I have to go in early. This is adapted from a recipe on the BBC website.

40g blackcurrents
75g sultanas
110g butter, softened
110g caster sugar
2 large eggs
large ripe bananas
225g Doves gluten-free plain flour
2 tsp baking powder
½ tsp salt
1kg loaf tin, lined with parchment paper

1. Preheat the oven to 180C/350F/Gas 4.
2. Cream the butter and sugar together until pale, light and soft. Add the eggs, one by one, and beat well between each addition.
3. Mash the bananas and add to the creamed mixture. Sift the flour, baking powder and salt together and fold carefully into the banana mixture. Very gently, stir in the blackcurrents and sultanas, so that they are evenly distributed through the mixture.
4. Pour the mixture into the loaf tin and bake in the oven for about 1½ hours until golden on top and a skewer inserted into the centre comes out clean.
5. Remove the loaf from the tin and cool on a wire rack.
