01 - Preheat oven to 325°F. Line a 12-cup muffin tin with paper liners.
02 - Mix graham cracker crumbs, sugar, and melted butter until combined. Divide evenly among liners, about 1 tablespoon each, pressing firmly to form a crust.
03 - Bake the crusts for 5 minutes, then let cool slightly.
04 - Beat cream cheese and sugar until smooth and creamy. Add egg, vanilla, lemon juice, and lemon zest; beat until just combined. Fold in sour cream.
05 - Divide the cheesecake batter evenly among the crusts.
06 - Heat blueberries, sugar, and lemon juice in a small saucepan over medium heat until berries burst, 3–5 minutes. Let cool slightly.
07 - Swirl a spoonful of compote on top of each cheesecake. Bake for 15–17 minutes, until centers are just set.
08 - Cool in pan for 30 minutes, then refrigerate at least 1 hour before serving.
09 - Garnish with fresh blueberries and extra lemon zest if desired. Serve chilled.
