Preheat your oven to 325°F (160°C).

Grease a 9×5-inch loaf pan thoroughly with butter or cooking spray, and line the bottom with parchment paper.

In a large mixing bowl, cream the softened unsalted butter and granulated sugar until light and fluffy.

Incorporate the large eggs into the butter and sugar mixture one at a time, mixing well after each addition.

In a separate bowl, whisk together the all-purpose flour, baking powder, ground cinnamon, ground nutmeg, and salt.

Gradually add the dry ingredients to the wet mixture, alternating with the orange juice, mixing on low speed.

Gently fold in the mixed dried fruits and chopped nuts using a spatula.

Pour the batter into the prepared loaf pan and smooth the top evenly.

Bake for 60-75 minutes, checking for doneness with a toothpick.

Once baked, let it cool in the pan for about 15 minutes, then transfer to a wire rack to cool completely.
