Reduce the oven temperature to 325º.
In a high-powered blender or a food processor (I use my Vitamix), blend the soaked cashews, coconut cream, coconut yogurt, maple syrup, fresh lemon juice, arrowroot starch, vanilla extract, and sea salt. Scrape down the sides of the container or use the tamper as necessary to get a super smooth consistency. It will take about 3 to 5 minutes of blending to get it super smooth and creamy.
1½ cup raw cashews, ¾ cup coconut cream, 1 cup vegan coconut yogurt, ⅓ cup (111g) pure maple syrup, 3 tablespoons arrowroot starch, 2 tablespoons fresh lemon juice, 1 teaspoon vanilla extract, ½ teaspoon sea salt
Taste the mixture and adjust to your tastes (add more maple syrup for sweetness, lemon juice for tanginess, or vanilla extract for more vanilla flavor). Pour the filling into the cooled crust and tap the pan hard on the counter a few times to release any air bubbles.
Bake for 45 to 55 minutes, or until mostly set. The cheesecake should jiggle slightly in the center when it’s ready, but not be too wet and jiggly. Try not to disturb the cheesecake for the first 45 minutes.
When the cheesecake is just shy of set, turn off the oven, leaving the cheesecake inside. Leave the oven door open a few inches and let the cheesecake cool inside the slightly ajar oven. Remove from the oven after about an hour.
Chill in the refrigerator for at least an hour to chill all the way through.
