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. Drizzle 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 using the back of a spoon or a small glass to create a compact, even base. Place 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 whisk.
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, filling each liner nearly to the top. Smooth the surfaces with a small offset spatula or the back of a spoon.
08 - Refrigerate for at least 3 hours, or until the filling is firm and fully set.
09 - Before serving, top each mini cheesecake with orange segments, a sprinkle of orange zest, and fresh mint leaves, if desired.
