These cheesecakes have a ton of flavor with the cookie crust and the plump, fresh blueberries on top. Make the cakes ahead of time and add the preserves (I love Bonne Maman Wild Blueberry Preserves) and berries right before you serve.Plan Ahead Note: cream cheese needs to be softened to room temperature and the eggs also need to be brought to room temperature. These cakes taste best if refrigerated overnight.
