Preheat oven to 350°F (180°C) and line a muffin pan with paper liners.
In a bowl, combine graham cracker crumbs and melted butter until mixture resembles wet sand.
Divide the crumb mixture into the liners, about 1 to 2 tablespoons each, and press firmly with the bottom of a cup.
Bake crusts for 5 minutes. Remove and let cool while preparing the cheesecake filling.
In a mixing bowl, beat cream cheese and sugar until smooth, about 1 to 2 minutes.
Add vanilla extract and then eggs, mixing just until combined, taking care not to overmix.
Evenly divide the cheesecake batter into the prepared crust-lined muffin cups, filling nearly full.
Bake for 15 to 17 minutes, until centers are slightly jiggly.
Cool to room temperature, then refrigerate for at least 4 hours until set.
Before serving, top each mini cheesecake with whipped cream and fresh berries.
