In a bowl, combine the mixed dried fruits, chopped dried cherries or apricots, rum, and orange juice. Let the mixture soak for at least 24 hours, or up to a week, to allow the flavors to meld.
Preheat your oven to 325°F (165°C). Grease and flour a 9-inch round cake pan or a loaf pan.
In a medium bowl, whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, and cloves.
In a large bowl, beat the softened butter and brown sugar until light and fluffy. Add the eggs, one at a time, beating well after each addition.
Gradually add the dry ingredients to the butter mixture, mixing until just combined. Stir in the soaked fruit mixture, nuts, crystallized ginger (if using), vanilla extract, molasses, and black treacle (if using).
Pour the batter into the prepared pan and smooth the top. Bake in the preheated oven for 50-60 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 to a wire rack to cool completely.
Enjoy your meal!
