Preheat your oven to 400°F (200°C). Grease an 8-inch springform pan with a little coconut oil or line it with parchment paper.
In a high-speed blender, combine the soaked cashews, coconut cream, maple syrup, lemon juice, and vanilla extract. Blend until completely smooth and creamy.
Add the cornstarch, baking powder, salt, nutritional yeast (if using), and apple cider vinegar to the blender. Blend again until all ingredients are well incorporated and the mixture is smooth.
Pour the cheesecake batter into the prepared springform pan, smoothing the top with a spatula.
Bake in the preheated oven for 30-35 minutes, or until the top is dark golden brown and the edges are set but the center is still slightly jiggly.
Remove from the oven and let cool at room temperature for about 1 hour. Then, refrigerate for at least 4 hours or overnight to set completely.
To serve, carefully remove the cheesecake from the springform pan. Slice and enjoy!
