Measure out all the chai spices and mix together in a small bowl. Set aside. We'll use this in the oat crust and the filling.
Preheat oven to 350F.
Add the oats, brown sugar, salt and 2 teaspoons of the chai spices into a food processor. Pulse until smooth. Add to a large bowl and stir in melted vegan butter until you can pinch it will your fingers and it stays together.
Line a 6" cake pan with parchment and add in the oat crust mixture. Use your hands to pat down the crust on the bottom of the pan and up the sides. Set aside.
Boil the cashews for 15 minutes to soften them.
In a high speed blender add the softened cashews, silken tofu, vegan cream cheese, organic cane sugar, lemon juice, the remaining chai spices and salt. Blend until completely smooth.
Pour the filling in to the prepared oat crust and bake for 45-50 minutes or until it's firm but has a slight jiggle. Let cool completely at room temperature. The cheesecake will firm up as it cools.
Once cool, cover and refrigerate overnight. Next day, top with homemade coconut whip cream or store-bought vegan cool whip. Sprinkle with some cinnamon and serve! Store leftovers in the fridge. Enjoy!
