Preheat your oven to 325°F (160°C) and line a 12-cup muffin pan with paper liners.
Crush the cookies into fine crumbs and mix with melted butter. Press the mixture firmly into the bottom of each cupcake liner to form a crust.
In a medium bowl, beat the cream cheese and sugar until smooth and creamy.
Add the egg and vanilla extract, mixing until just combined.
Fold in the white chocolate chips and blueberries gently.
Spoon the mixture evenly over the crusts in the liners.
Bake for 20–25 minutes or until the centers are set.
Let cool completely, then chill in the refrigerator for at least 2 hours.
Optional: Drizzle with melted white chocolate before serving.
