01 - Combine crushed crackers, melted butter, and granulated sugar in a mixing bowl. Stir until completely blended and the consistency resembles wet sand.
02 - Divide the crust mixture among twelve mini muffin cups lined with paper liners or lightly greased. Press firmly into the bottom of each cup to create a compact base.
03 - Beat softened cream cheese and powdered sugar together in a separate bowl using an electric mixer or whisk until smooth. Add pumpkin purée, pumpkin pie spice, and vanilla extract; mix until the filling is creamy and homogeneous.
04 - Spoon or pipe the pumpkin cheese filling onto each prepared crust base, smoothing the surface of each.
05 - Transfer the mini pies to the refrigerator and chill for a minimum of one hour to ensure the filling is set.
06 - Before serving, dollop each mini pie with whipped cream and sprinkle with a pinch of ground cinnamon as desired.
