24 hours before you want to bake your fruit cake, chop and combine dried fruit in a large mixing bowl. Pour rum over all the fruit and give it a good mix. Cover this and let it sit out at room temperature for at least 24 hours. You may choose to let it soak longer if you wish.
When your fruit has soaked for at least 24 hours and you are ready to bake preheat your oven to 325 degrees.
In a large mixing bowl, combine flour, baking powder, salt, spices and citrus zests. Set aside.
In another mixing bowl cream butter and sugar together. Add eggs one at a time until combined.Slowly add in the orange juice.
Grate one granny smith apple and add it to the mixture.
Fold in dry ingredients until just combined.
Finally, fold in the soaked fruit mixture.
Prepare a cupcake tin with paper liners.
Use a small ice cream scoop to fill each cupcake cavity 2/3 of the way with the mixture.
Bake for 22-24 min.
