Preheat your oven to 325°F (160°C). Prepare a loaf pan with parchment paper.

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

Add in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

In a separate bowl, whisk together the flour, baking powder, and cinnamon.

Gradually add dry ingredients to the wet mixture, mixing until just combined.

Fold in the mixed dried fruits and nuts until evenly distributed throughout the batter.

Pour the batter into the prepared loaf pan and smooth the top with a spatula.

Bake for 60-70 minutes, or until a toothpick inserted into the center comes out clean.

Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack.

Once cooled, brush with dark rum or brandy for added flavor, if desired. Wrap tightly in plastic wrap and store.
