Line an 8x8 baking dish with parchment paper. Set aside.Puree raspberries until completely smooth. Set aside.In a double boiler (I use a glass bowl nested in a small cooking pot), melt together coconut butter, coconut oil, and maple syrup until creamy smooth.Pour coconut mixture into parchment-lined pan. Drizzle raspberry puree over the top. Drag and swirl a toothpick through raspberry puree to create a marble effect.Place in freezer until solid- at least an hour. Cut into squares. Store in fridge or freezer.
