Vegan Triple Chocolate Mousse Cake

1. To soak the cashews. Place the cashews in medium pot and cover with water. Bring to a boil over high heat. Boil 2 minutes, then cover and remove from the heat. Let the cashews soak for at 30 minutes or up to overnight. Drain well. 
2. Meanwhile, make the crust. Line an 8-inch spring form pan with parchment paper. In a food processor, combine the walnuts, coconut, dates, cocoa powder, and a pinch of salt. Pulse until finely ground and the mix forms a ball, about 2-3 minutes. Press the mixture into the bottom of the prepared pan, making sure to pack it in tightly.
3. To make the mousse. Add the drained cashews, coconut milk, cocoa powder, instant coffee, vanilla, and maple syrup to a food processor or high powered blender. Pulse until smooth and creamy, scraping down the sides as needed, about 5 minutes. Taste, adding more maple syrup if needed to sweeten. Pour the mixture evenly over the crust. Press a piece of plastic wrap over the mousse. Transfer to the fridge and chill for at least 2 hours, or overnight.If you mouse is still pudding like, transfer to the freeze and freeze until firm.
4. In a small, microwave safe bowl, melt together the chocolate and peanut butter until smooth, about 30 second to 1 minute. Let cool 5 minutes and then spread the chocolate overtop the cake. Return to the fridge to set up, about 10 minutes or until ready to serve. 
5. Slice and serve! Keep the cake stored in the fridge (or in the freeze if your mousse is on the looser side*).
