Preheat the oven to 325°F and line a standard muffin pan with cupcake liners. Set aside.
In a large mixing bowl, combine the graham cracker crumbs and sugar, stirring until evenly mixed. Pour in the melted butter and stir until the mixture is well coated.
Divide the crust mixture evenly among the 12 liners, pressing it firmly into the bottom to create a solid base.
Bake for 5 minutes until lightly golden, then remove from the oven and set aside to cool.
In a stand mixer fitted with a paddle attachment, beat the cream cheese and sour cream on medium speed until smooth.
Add the sugar and vanilla extract, mixing until fully combined. Scrape down the sides of the bowl as needed.
Reduce the mixer speed to low and add the eggs one at a time, mixing just until incorporated.
Pour the batter evenly into the prepared liners, filling each nearly to the top.
Bake for 17-20 minutes, or until the tops are set.
Remove from the oven and let the cheesecakes cool in the pan for one hour.
Carefully take them out of the pan and refrigerate in an airtight container for at least 4 hours or overnight.
Before serving, top each cheesecake with a spoonful of blueberry pie filling.

Notes
Lightly spray cupcake liners with non-stick spray before filling—this helps the cheesecake pull away cleanly after baking.
Use a cookie scoop or measuring cup to evenly portion the crust and filling for consistent sizes.
Tap the muffin tin gently on the counter before baking to release air bubbles from the batter.
Let them cool completely in the pan before removing—this helps them firm up and hold their shape.
For best flavor and texture, chill for at least a few hours or overnight before serving.
