01 - Preheat oven to 325°F. Line a 12-cup muffin tin with paper liners.
02 - Combine graham cracker crumbs, sugar, and melted butter in a bowl until well mixed. Divide mixture evenly among liners, about 1 tablespoon each, and press firmly to form crusts.
03 - Bake crusts for 5 minutes, then set aside to cool slightly.
04 - Beat cream cheese and sugar in a mixing bowl until smooth and creamy. Add egg, vanilla extract, lemon juice, and lemon zest; beat until just combined. Gently fold in sour cream.
05 - Distribute cheesecake batter evenly among the prepared crusts.
06 - Heat blueberries, sugar, and lemon juice in a small saucepan over medium heat for 3–5 minutes until berries burst and release juices. Remove from heat and let cool slightly.
07 - Spoon a small amount of cooled compote onto each cheesecake and swirl gently with a toothpick. Bake for 15–17 minutes until centers are just set.
08 - Let cheesecakes cool in the pan for 30 minutes, then refrigerate for at least 1 hour before serving.
09 - Top each cheesecake with fresh blueberries and additional lemon zest just before serving.
