01 - Line a standard muffin tin with paper liners or prepare 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 and resembles wet sand.
03 - Divide the crumb mixture evenly among the prepared liners. Press down firmly with the back of a spoon or measuring cup to create a compact, even layer. Place the tin in the refrigerator to chill while preparing the filling.
04 - In a medium bowl, beat the cream cheese and powdered sugar together until completely 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, fresh orange juice, and vanilla extract. Fold until smooth and uniformly combined, being careful not to deflate the cream.
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 cheesecakes are fully set and firm to the touch.
09 - Before serving, top each cheesecake with orange segments, a sprinkle of orange zest, and fresh mint leaves if desired.
