Cut the fruit loaf slices in half vertically and butter both sides.
Layer into a large ovenproof dish, slightly overlapping.
Spoon over apple slices and sprinkle on the walnuts and raisins.
In a bowl, whisk together the custard and 2 eggs, then drizzle the mixture over the bread and tin apples.
Mix the brown sugar and cinnamon together in a bowl and sprinkle cinnamon sugar over the top of the pudding.
Bake in the oven for 30 minutes or until browned.
Remove from the oven and using a pastry brush, brush the extra melted butter over the top of the pudding.
