01 - Line a standard muffin tin with paper liners or use silicone molds.
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.
03 - Divide the crumb mixture evenly among the liners, pressing down firmly to create a compact, level base. Place the tin in the fridge to chill while preparing the filling.
04 - In a medium bowl, beat the cream cheese and powdered sugar together until smooth and creamy.
05 - In a separate chilled bowl, whip the cold heavy cream to stiff peaks using a hand mixer or stand mixer.
06 - Gently fold the whipped cream into the cream cheese mixture. Add the orange zest, orange juice, and vanilla extract, folding until smooth and uniformly combined.
07 - Spoon or pipe the filling over the chilled bases, dividing it evenly. Smooth the tops with a spatula.
08 - Refrigerate for at least 3 hours, or until the filling is fully set and firm to the touch.
09 - Before serving, top each cheesecake with orange segments, a sprinkle of zest, and fresh mint leaves if desired.
