Preheat oven to 180°C. Lightly grease a 20cm x 30cm slice tin, line with non-stick baking paper.
Place the flour, sugar and butter in a large bowl and mix well to combine. Remove half (635g) of the streusel mix into the lined baking tray. Press with the back of a spoon to form an even base, then refrigerate for 10 minutes. Then bake for 20-25 minutes or until golden brown. Set aside.
To make the filling, place the butter, apples, sugar, nutmeg, all spice and mixed spice into a large saucepan with a lid, over a high heat and cook for 5 minutes. Remove the lid and cook for 3 minutes or until the apples are soft. Drain off any liquid then add the fruit mince and the lemon zest to the cooked apple.
To the remaining streusel mix add the almonds, mixed spice and cinnamon, mix until well combined.
Spoon the filling evenly over the base. Sprinkle the streusel mix over the filling.
Bake for 35-40 minutes or until golden brown. Allow to cool in the tin on a wire rack. Once cool cut into slices.
