Melt chocolate, peanut butter, condensed milk, and butter in microwave. Add a cup of shredded coconut. Disperse into a square pan. Refrigerate until solid. In the meantime, mix 1 cup of powdered sugar, ½ cup peanut butter, ¼ cup maple syrup, and 4 tablespoons of water in a saucepan on a stove top, until smooth. Finally, spread the icing on top of the fudge, and sprinkle with some shredded coconut. Place back in refrigerator for an additional 15-30 minutes or until thickened.
