Preheat oven to 160°C (320°F) and line mini cake pans with parchment.
Combine dried fruits with a tablespoon of flour and set aside.
In a bowl, cream the softened butter and brown sugar until light and fluffy.
Add eggs one at a time, mixing well after each addition.
Sift together flour, baking powder, and spices, then fold into the butter mixture.
Gently fold in the floured dried fruits.
Spoon the batter into prepared pans and smooth the tops.
Bake for 20-25 minutes, or until a toothpick comes out clean.
Allow cakes to cool in pans for 10 minutes before transferring to wire racks.
To make ganache, heat cream until just boiling, then pour over chopped chocolate.
Let the ganache sit for 5 minutes, then stir until smooth.
Spread the ganache over the cooled mini cakes.
