01 - Line a standard 12-cup muffin tin with paper liners, or arrange silicone molds on a flat baking sheet.
02 - Pulse the biscuits in a food processor until fine crumbs form. Pour in the melted butter and pulse until the mixture resembles wet sand and holds together when pressed.
03 - Divide the crumb mixture evenly among the prepared liners, using about 1 tablespoon per cup. Press down firmly with the back of a spoon or a small flat glass to create a compact, even layer. Place the tin in the refrigerator while preparing the filling.
04 - In a medium mixing bowl, beat the room-temperature cream cheese and powdered sugar together using a hand mixer or stand mixer on medium speed until completely smooth and free of lumps.
05 - In a separate chilled bowl, whip the cold heavy cream on medium-high speed until stiff peaks hold their shape when the beaters are lifted.
06 - Gently fold the whipped cream into the cream cheese mixture using a spatula. Add the orange zest, fresh orange juice, and vanilla extract, then fold until evenly incorporated and the filling is smooth. Avoid overmixing to keep the mixture light and airy.
07 - Spoon or pipe the filling over the chilled crust bases, dividing it evenly among all six cups. Smooth the tops with a small offset spatula or the back of a spoon.
08 - Refrigerate the cheesecakes for at least 3 hours, or until the filling is firm and set throughout.
09 - Before serving, top each cheesecake with orange segments, a pinch of extra orange zest, and a few fresh mint leaves if desired.
