From a recipe on the NYT Cooking app. It uses a mix of shredded and flaked coconut which gives the end result a nice combination of absorption and texture. Many recipes including this one call for sweetened coconut, but I (and many comments on the recipe) think it's fine with unsweetened.
Thanks! I got most of the way through the recipe and realized it called for bittersweet chocolate, whereas I only had chocolate chips and unsweetened baking chocolate. But I just mixed them and it came out tasty.
