These are great bars, even with the light version (only one third the fat). I used fat free condensed milk, Smart Balance, only 1 cup of coconut, milk instead of cream (and yes, it worked wonderfully!), low fat chocolate graham crackers, and no powdered sugar or white chocolate. Who doesn't love chocolate, coconut and nuts together? They are a sublime combination. I liked that with less coconut, the three were equally balanced, but I am sure using the full amount of coconut would also be delicious, and much more like a macaroon than a magic bar. I did not keep these refrigerated, so I could avoid bloom (white spots), and they were fine stored at room temperature. Thanks for this yummy treat!
