This recipe is based on the popular Filipino dessert mango graham cake which my sis-in-law made for the family in large batches when we were all in Kottayam last year. The best part about this dessert is that it uses delicious graham crackers, ripe and sweet mangoes, and condensed milk. No cooking, no baking. Just mix, layer, refrigerate, and bham – eggless no bake mango biscuit cake is ready!
