Recipe wise, there’s actually no difference apart from the fact that the Kada Prashad is usually plain, without any nuts or dry fruits in it. Ingredient wise Kada Prashad has more ghee than the atta halwa. Another thing that distinguishes the two is the fact that since Kada Prashad is a prasad served in gurudwaras, it is made with a lot of devotion. Thus, automatically has a divine taste.
