Pre-heat oven to 350 degrees F.
In a big bowl, combine carrots, sugar and melted butter.
Pour the boiling water to this.
In another bowl, mix all the other ingredients (chopped walnuts, pitted dates, whole wheat flour, nutmeg powder, sodium bicarbonate, salt & vanilla essence).
Add the flour mixture to the carrot mixture. Mix together the dry & wet ingredients well.
Pour this to a greased 9" round cake pan. Bake for 40 to 45 minutes.
