01 - Line a standard muffin tin with paper liners or arrange silicone molds on a flat tray.
02 - Pulse the biscuits in a food processor until fine crumbs form. Pour in the melted butter and blend until the mixture is evenly moistened and resembles wet sand.
03 - Divide the crumb mixture evenly among the liners, pressing down firmly with the back of a spoon or a small measuring cup to create a compact, even layer. Place in the refrigerator while preparing the filling.
04 - In a medium bowl, beat the cream cheese and powdered sugar together using a hand mixer or stand mixer until completely smooth and creamy, scraping the sides as needed.
05 - In a separate chilled bowl, whip the cold heavy cream to stiff peaks, being careful not to overbeat.
06 - Gently fold the whipped cream into the cream cheese mixture in two additions. Add the orange zest, fresh orange juice, and vanilla extract, folding until smooth and uniformly combined.
07 - Spoon or pipe the filling evenly over the chilled crust bases, filling each liner to just below the rim. Smooth the tops with an 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 sprinkle of orange zest, and fresh mint leaves as desired.
