Heat the sultanas with the rum. Bring to the boil, cover and leave for half an hour, if possible (but not vital). Use the microwave or a saucepan
Set the oven to 150°C fan, gas mark 3
Grease a 2lb loaf tin with butter or use a paper liner
Melt the butter. About 30 seconds on HIGH in the microwave
For the Banana Loaf:
Chop the nuts. Pulse a few time in the processor until they're the right size - don't overdo it!
Take the nuts out and put them aside
Put all the ingredients except the banana, dried fruit, and nuts into the processor and blitz for about a minute. Scrape down and blitz for 10 seconds.(Eggs, sugar, flour, baking powder, bicarb, salt, butter, vanilla)
Add the bananas and pulse a few times until they're incorporated. If the bananas aren't totally ripe you will have some lumps - just mash them in with a fork
Add the nuts and sultanas and mix with a spoon to avoid obliteration
Spoon into the prepared tin
Bake for 1-1 ¼ hours, but check after 1 hour. The cake will be done when the top is brown and a cocktail stick comes out clean
Cool in the tin.
Notes
Everyday Cooks Tips:
Although the recipe uses a food processor, you can use any sort of mixer with these modifications:
Chop the nuts roughly with a sharp knife
Mash the banana with a fork before mixing in
To freeze, leave the cake in the paper wrapper, wrap in foil and seal in a plastic bag or box. Freeze for up to 3 months
Store in the fridge in the liner in an airtight plastic box for a week or two.
