Preheat your oven to 350°F (175°C) and line a 9-inch cake tin with parchment paper.
In a bowl, sift together flour, baking powder, cinnamon, cloves, and nutmeg.
In a separate large bowl, cream the butter and brown sugar until fluffy. Beat in the eggs, one at a time, then mix in the lemon zest.
Gradually add the dry ingredients to the butter mixture, alternating with milk, until just combined.
Fold in the currants, apricots, and candied peel.
Transfer the mixture into your lined cake tin, leveling off the surface for an even bake.
Allow the cake to bake for 35-40 minutes. It's ready when a toothpick inserted into the middle of the cake comes out without any wet batter.
Allow the cake to cool in the tin for 10 minutes before transferring it to a wire rack to cool completely.
Dust with powdered sugar before serving.
