01 - Combine graham cracker crumbs, melted butter, brown sugar, and cinnamon in a medium bowl. Mix until evenly moistened and well blended.
02 - Distribute approximately 2 heaping tablespoons of crust mixture into each of six 4-ounce mini mason jars. Press firmly using the back of a spoon to create an even base layer.
03 - Beat softened cream cheese in a large mixing bowl until completely smooth. Incorporate sour cream, granulated sugar, vanilla extract, cinnamon, nutmeg, ginger, and cloves. Continue mixing until fully combined and creamy throughout.
04 - In a separate chilled bowl, whip cold heavy cream using a hand or stand mixer until stiff peaks form and the cream holds its shape.
05 - Gently fold the whipped cream into the cream cheese mixture using a spatula, taking care to maintain airiness. Continue folding until no white streaks remain and the filling is uniformly smooth and light.
06 - Spoon the cheesecake filling evenly among the prepared jars, layering it over the crust. Use the back of a spoon to smooth and level the surface of each portion.
07 - Cover each jar tightly with its lid. Refrigerate for a minimum of 3 hours, allowing the cheesecake to firm completely before serving.
08 - Top each cheesecake with a dollop of freshly whipped cream and a light dusting of ground cinnamon or nutmeg immediately before serving, if desired.
