The Samoa Pie was born on Pi Day. I was baking an easy 5-ingredient Pi Day pie to celebrate and as I pulled the toasted coconut crust out of the oven, I thought, hey! It’s like a Samoa [my very favorite of all the Girl Scout Cookies]! So I put my head down determined to add a layer of chewy caramel to the creamy chocolate original. Did it work? You betcha.The original pie, while an easy showstopper, is rich: like eating a slice of decadent chocolate truffle with a macaroon cookie crust (cue the sound of Mounds lovers rejoicing). And while adding another sweet layer to the pie might not seem like it would offer balance, it does. The chocolate coconut filling ends up being kind of one deep base note, but an added layer of salted caramel adds a brightness and a salinity that the recovering chocoholics were craving. Make this ahead, just bring it to room temperature before serving for easy slicing.
