Preheat the oven to 180°C.
Line your pan with parchment paper. Beat the butter and sugar with an electric mixer until combined. Add the eggs one at a time, mixing well after each addition.
Add half the flour, baking powder, and vanilla along with half the milk, and once combined, add the remaining flour and milk, mixing just until combined.
Fold in the dried fruit and nuts by hand, without the electric mixer. Pour into the pan and bake for 45 minutes to an hour depending on the size of your pan.
Meanwhile, mix the syrup ingredients together and heat until it reaches the right consistency. Toss the dried fruit and nuts you're using for decoration into the thickened syrup, and once the cake is out of the oven and cooled, decorate the top with this mixture.
