Place the raw pecans, softened coconut oil, pitted Medjool dates, lemon zest, sea salt, and ground cinnamon in your food processor. Blend on high until the mixture resembles a crumbly dough that holds together when pressed but still has some texture.
Press the crust mixture firmly into the bottom of a 9-inch springform pan. Use your fingers or the back of a measuring cup to pack it tightly and evenly. Place it in the refrigerator while preparing the filling.
Drain and rinse the soaked cashews, then add them to the food processor along with fresh lemon juice, pure maple syrup, full-fat coconut milk, and a few tablespoons of water. Blend on high until completely smooth and creamy. Add more water one tablespoon at a time to reach desired consistency.
Pour the smooth filling over the prepared crust in the springform pan. Use a spatula to spread evenly. Tap the pan gently on the counter to remove air bubbles.
Cover the cheesecake with plastic wrap and place it in the refrigerator. Chill for at least 4 to 6 hours or overnight for best texture.
Carefully remove the sides of the springform pan. Slice the cheesecake into wedges and serve as is or topped with your favorite fruits, chocolate drizzle, or nuts.
