Cream the butter and sugar together in a stand mixer, or in a large bowl with an electric whisk, beating for at least 2-3 minutes until really pale, then add the treacle. Sift the flour, baking powder and a pinch of salt into a separate bowl. Add 1 egg at a time to the mixer, plus a spoonful of the flour mixture, making sure each egg is mixed in well before you add the next.
Fold in the rest of the flour using a large metal spoon. Tip in the soaked fruits and any liquid remaining in the bowl, and fold through until evenly combined. Scrape into the prepared tin, level the surface and cover the cake tin with a double layer of baking paper, with a small hole cut into the centre. Bake for 2 ½-3 hours, or until the cake is firm, golden brown and a skewer inserted in the centre comes out clean.
Cool the cake in the tin, then unmould and remove the lining papers once completely cold. Wrap in fresh paper and foil before storing in an airtight container. The cake is lovely and moist, but if you wish you can feed the cake with a tablespoon of rum every week or so. Don’t overdo the feeding process though, or the cake will disintegrate into a mess of boozy crumbs! Finish feeding the cake at least a week before you plan to ice it, so that the surface of the cake isn’t damp.
