Pre-Preheat oven to 180°C. Grease and line base and sides of a 27cm x17cm slice pan with baking paper, extending paper over sides.
Combine fruit and rum or juice in saucepan and bring just to the boil. Set aside to cool, stirring occasionally. Set aside 1/4 cup of the fruit mixture for decorating the top.
Heat butter and chocolate in saucepan over low heat and stir until melted and combined. Set aside to cool 10 minutes.
Whisk sugar and eggs together in large bowl, then whisk in cooled chocolate mixture and remaining soaked fruit. Sift flour, cocoa and baking powder into the bowl and add half of the hazelnuts (saving some for the top). Stir until combined. Pour into prepared pan and scatter with reserved fruit and nuts.
Bake for 40-45 minutes or until tested with a skewer. Some crumbs will cling to the skewer. Allow to cool in the pan for 30 minutes before removing. Cut into 18 pieces and serve warm and gooey or cool and fudgy.
