Yum! My recipe for those bars calls for a 9x13. And walnuts in addition to the coconut, butterscotch and chocolate bits. I wouldn’t use an 8x8 for those cookies because they’d be heavy and dense if they were thick. Well, they’re heavy and dense anyway, but if they were too thick they’d be hard to bite.

and here’s the recipe, right from the condensed milk can:
