Method

Heat the oven to 160C (180C non-fan) and line a couple of flat baking trays with baking paper. Peel and coarsely grate the carrots.

In a large bowl mix together the butter and sugar until smooth. Add the egg and mix, then add the baking powder, mixed spice, flour, grated carrot, coconut, sultanas, walnuts, a pinch of salt and the orange zest. Mix together until just combined.

Heap 1 dessertspoonful of mix onto the trays in rows of 3 — do not flatten and make sure there is plenty of spread room (you should get about 8 per tray, but you may need to bake in batches).

Place into the oven and bake for 12-14 min (12 min if you like them super-chewy and gooey).

Remove from the oven and place on a wire rack to cool — the cookies will firm on cooling.

Mix the orange juice with the icing sugar until you have a thick, smooth consistency and drizzle over the cookies.
