Preheat the oven to 350°F (177°C). Lightly coat 4-inch (10 cm) mini tart pans with removable bottoms with cooking spray.

For the crust, place the gingersnap cookies in a food processor and pulse into fine crumbs until you have 2 cups (200 g).
2 cups (200 g) ginger snaps cookie crumbs
Transfer the crumbs to a medium bowl and stir in the granulated sugar and melted butter until evenly moistened.
3 tbsps (38 g) granulated sugar, 6 tbsps (85 g) unsalted butter
Divide the mixture evenly among the tart pans, pressing it firmly into the bottoms and up the sides. Use the bottom of a measuring cup to create a compact, uniform crust.
Set the pans on a baking sheet and bake for 7 minutes, or until the crusts are lightly fragrant and set. Remove from the oven and let cool slightly.
For the filling, lightly whisk the egg in a medium bowl, then add the granulated sugar, salt, cinnamon, ginger, and cloves.
1 large egg, ½ cup (100 g) granulated sugar, ¼ tsp (1.5 g) table salt, ½ tsp (1.3 g) ground cinnamon, ¼ tsp (0.5 g) ground ginger, ¼ tsp (0.5 g) ground cloves
Whisk in the evaporated milk and pumpkin purée until smooth and fully combined.
¾ cup (180 ml) evaporated milk, ½ can (7.5 oz / 213 g) pumpkin purée
Pour the filling into the cooled crusts, dividing it evenly among the tart pans. Place the filled tarts on a baking sheet and bake for about 25 minutes, or until the filling is set but still slightly jiggly in the center. The filling will puff slightly as it bakes, then settle as it cool
Transfer the tarts to a wire rack and let cool completely at room temperature.
Once cooled, refrigerate for at least 2 hours or overnight to allow the filling to firm.
Carefully remove the chilled tarts from their pans before serving. Top each tart with whipped cream.
