Preheat your oven to 180C/160C fan.
Line a 9-inch square baking tin with parchment and set aside.
Add the wholemeal flour, plain flour, bread soda, baking powder, salt, and spices to a bowl and mix well. Make a well in the centre.
Add the oil, eggs, yoghurt, and honey, and mix to combine.
Add the grated carrot and currants and mix through (use the largest side of the grater, you want visible strands of carrot, not a fine mush).
Spoon the mixture into the lined tin.
Bake in the preheated oven for 45-50 minutes.
Remove and allow to cool completely.
Once cold, cut into bite-sized pieces.
To serve, top each piece with a small spoon of yoghurt and a little grated carrot.
