Brush the bottom of an 8″ springform pan with vegan butter and press crust evenly into the bottom of the pan.
Add the oat milk and 3/4 cup of sugar and heat on medium heat just until the sugar is dissolved and melted. Set aside and let it cool.
In a high power blender, blend soaked cashews, cooled oat milk mixture, melted vegan butter, vanilla, until thick and smooth.
Add the vegan cheese cream and orange zest into the blender and mix for a few seconds until the cream cheese mixture is well combined..

Carefully remove the cheesecake while still frozen from the springform and transfer to a large plate.
Decorate the top edge of the cheesecake with fresh blueberries.
Thaw for 1 hour and serve.
