Preheat your oven to 400°F (200°C). Grease an 8-inch round springform pan and line the bottom with parchment paper for easy removal.
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, and salt 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 deeply golden brown and the edges are set while the center remains slightly jiggly.
Turn off the oven and leave the cheesecake inside for an additional 30 minutes to cool gradually.
Remove from the oven and let it cool to room temperature before transferring to the refrigerator. Chill for at least 4 hours or overnight for best results.
Once chilled, carefully remove the cheesecake from the springform pan and slice to serve.
