02 - Combine crushed chocolate cookies and melted butter in a bowl. Mix until crumbs are evenly moistened.
03 - Divide crumb mixture evenly among liners (about 1 tablespoon per cup). Press down firmly to form bases.
04 - Beat cream cheese and granulated sugar in a large bowl until smooth and creamy.
05 - Add egg, vanilla extract, and sour cream. Beat until just combined—avoid overmixing.
06 - Spoon cheesecake filling evenly over each crust (about 2 tablespoons per cup). Smooth tops.
07 - Bake for 16 to 18 minutes until centers are just set (slight jiggle is normal).
08 - Cool in tin for 30 minutes, then refrigerate for at least 2 hours.
09 - Whip heavy cream with powdered sugar until stiff peaks form.
10 - Pipe or dollop whipped cream on each cheesecake. Garnish with Mini Eggs and pastel sprinkles. Serve chilled.
