In a food processor pulse together dates, pistachios, vanilla extract and sea salt. Transfer mixture into an 8-inch square casserole dish. With your hands press mixture together and down towards the dish so that the ingredients stick together, this layer will be the "crust". Next, in a food processor or blender combine raw cashews that have soaked in water overnight (or atleast for 1 hour) with coconut cream and coconut sugar and blend together until creamy. Spread this mixture as a second layer on top of the date and pistachio crust. Next in a high-speed blender, blend together raspberries with chia seeds and pour on top as the final layer. Place dish in the freezer to set overnight. Store in the freezer. Enjoy!
