01 - Line an 8-inch square pan with parchment paper, allowing overhang on sides for easy removal later.
02 - Pulse almonds, pitted dates, shredded coconut, and sea salt in a food processor until mixture sticks together when pressed. Press firmly and evenly into prepared pan to form crust layer.
03 - Combine soaked cashews, coconut cream, maple syrup, lemon juice, lemon zest, vanilla extract, and salt in a high-speed blender. Blend until completely smooth and creamy, stopping to scrape down sides as needed.
04 - Pour cashew cream mixture over crust and smooth top with spatula. Place pan in freezer for 1 hour or until cream layer is completely set.
05 - Combine blueberries, lemon juice, and maple syrup in small saucepan over medium heat. Cook, stirring occasionally, until berries begin to burst, about 3-4 minutes. Add cornstarch slurry and continue cooking, stirring constantly, until mixture thickens, 1-2 minutes. Remove from heat and cool completely.
06 - Spread cooled blueberry topping evenly over set cashew cream layer. Return to freezer for minimum 2 hours or until completely firm throughout.
07 - Use parchment overhang to lift dessert from pan. Let sit at room temperature 10 minutes before cutting. Use hot, sharp knife for clean slices, wiping blade between cuts. Serve chilled.
