Mix the Crust Ingredients: In a bowl, combine graham cracker crumbs, sugar, and melted butter. Stir until well combined.
Fill the Muffin Liners: Line a 12-cup muffin tin with paper liners. Spoon the crust mixture into each liner, pressing firmly to create an even layer. Refrigerate while preparing the filling.
Prepare the Raspberry Swirl:
Cook the Raspberry Mixture: In a small saucepan, combine raspberries, sugar, cornstarch, and water. Cook over medium heat, stirring frequently, until the mixture thickens (about 5 minutes). Strain to remove seeds, if desired, and let cool.
Prepare the Filling:
Mix the Cream Cheese and Sugar: In a large bowl, beat the softened cream cheese and sugar with an electric mixer until smooth.
Add the Egg and Vanilla: Mix in the egg and vanilla extract until just combined.
Incorporate the White Chocolate and Sour Cream: Gently fold in the melted white chocolate and sour cream until smooth.
Assemble and Bake:
Fill the Muffin Cups: Spoon the cheesecake filling over the prepared crusts, filling each cup about ¾ full.
Add the Raspberry Swirl: Drop small dollops of the raspberry mixture onto each cheesecake. Use a toothpick to create a swirl pattern.
Bake: Preheat the oven to 325°F (160°C). Bake for 18-20 minutes, or until the edges are set and the centers are slightly jiggly.
Cool and Chill:
Cool to Room Temperature: Let the cheesecakes cool in the pan for 30 minutes.
Chill: Refrigerate for at least 2 hours, or until fully set.
Serve and Garnish:
Remove Liners: Carefully remove the paper liners before serving.
Garnish: Top with fresh raspberries, white chocolate shavings, or mint leaves for an elegant finish.
