Super easy, super popular are the "magic cookie bars" the recipe's on the back of the sweetened condensed milk cans and the back of the nestle choc chip bags - they're amazing, super super delish and really easy.
you need one can of sweetened condensed milk, a bag of flaked cocconut, a bag of chocolate chips, graham cracker crumbs and I think that's it. Big hit! They are too easy yet seem "fancy".
