- Preheat the oven to 325°F. Line a muffin tin with paper liners. 
- In a medium bowl, combine graham cracker crumbs, 1/4 cup sugar, and melted butter. Mix until well combined. Press about 1 tablespoon of the mixture into the bottom of each muffin cup to form a crust. 
- In a large mixing bowl, beat the softened cream cheese and 1/2 cup sugar until smooth and creamy. Add the vanilla extract and coconut milk, and mix until well combined. If using gelatin, dissolve it in 2 tablespoons of warm water and stir it into the mixture. 
- Fold in the crushed pineapple gently until evenly distributed. 
- Spoon the cheesecake mixture over the crusts in the muffin tin, filling each cup about 3/4 full. 
- Bake for 20-25 minutes or until the edges are set but the centers are slightly jiggly. Remove from the oven and let cool to room temperature. 
- Refrigerate for at least 2 hours to set before serving. Top with shredded coconut before serving.
