Preheat the oven to gas 3, 170°C, fan 150°C. Grease and line the base and sides of a straight-sided, 33x25cm (13x9in) rectangular cake tin that is about 6cm (2½in) deep with nonstick baking paper.
Place the dried fruit, hazelnuts, flour, orange zest and spices into a large mixing bowl and stir to combine.
Beat the butter and sugar with an electric mixer until creamy and pale. Gradually whisk in the eggs. Add a little flour if necessary to help prevent curdling.
Add the egg mixture to the bowl of dry ingredients and gently stir to combine. Pour into the cake tin and use a spatula to lightly smooth the surface. Place in the centre of the oven and bake for 30 minutes. Reduce oven to gas 2, 150°C, fan 130°C and cook for a further 45-55 minutes until dark golden, firm, and a skewer comes out clean.
Set aside to cool, then turn out and leave upside down. Cut into squares.
