Black Banana Bread

with thanks to Nigel Slater for inspiration. However, my version is slightly different:

• 180g brown sugar and the same of butter 
• 3 eggs  
• 180g flour with a teaspoonful of baking powder
• one old banana at least a month old. For about two years, I haven't felt inclined to eat bananas, because they don't seem to have the correct taste, texture and ripeness.  This one was left in my cold larder when a visitor arrived at the end of October. 
• a handful of salted almonds (you could use walnuts)
• a large handful of chocolate GOJI berries
• a handful of oats
• drops of vanilla essence

1. Preheat a HOT oven and an oiled loaf tin or line with a baking paper container.
2. Beat the butter and sugar. 
3. Add eggs to butter and sugar mixture, then mix in toasted crushed ground almonds, flour, baking powder, vanilla extract, mashed banana and goji berries.
4. Mix well and pour into the tin. Dust with demerara sugar. Bake for about 1 hour.
