Preheat the oven to 350°F. Spray an 8-inch round spring form cake pan with cooking spray.
Make the crust. In a large bowl or stand mixer, mix the cassava flour, coconut flour, coconut sugar, and arrowroot starch. Stir to blend. In a separate small bowl, whisk together the melted coconut oil and maple syrup or coconut nectar. Pour the wet ingredients into the bowl with the dry ingredients.
Start beating on medium speed, increasing the speed and continue to beat until a crumbly dough is formed. The dough should be the consistency of damp, coarse sand. Gather the dough and press it firmly in the bottom of the cake pan. Bake for 10 to 12 minutes, then set aside to cool, about 20 to 30 minutes.
Meanwhile, make the filling. In a high-speed blender, mix the coconut milk, soaked cashews, mashed banana, coconut cream, vegan cream cheese, coconut nectar or maple syrup, beet root powder, and vanilla extract. Blend until creamy, using the tamper as you need to get the blender going and until everything is smooth. Add the melted coconut oil and blend again.
Pour the filling mixture into the cake pan with the crust. Transfer the cheesecake to the refrigerator to set, at least 12 hours or ideally overnight up to 24 hours. Serve and enjoy, or make the frosting.
To make the frosting, in a large mixing bowl, combine the coconut oil and palm oil shortening. Beat with a hand mixer until fluffy, about 1 minute.
Add the powdered monk fruit, beet root powder, starch and beat again. Add the maple syrup and vanilla and beat until everything is combined, using a spatula to scrape down the sides as needed.
Using a spatula, mix the frosting. Use the frosting immediately, spreading it evenly on top of the set and chilled cheesecake. Enjoy immediately (if put back in the fridge, the frosting will harden, but it is still delicious!).
