Beat the softened cream cheese in a medium bowl for 1–2 minutes until smooth, scraping the sides as needed.
Fold in the powdered sugar, pumpkin purée, cinnamon, nutmeg, ginger, cloves, salt, and vanilla. Mix until completely smooth.
Add 1 cup graham cracker crumbs and fold until fully incorporated. Cover and chill in the freezer for 30 minutes, or refrigerate for 2 hours.
Scoop about 2 tablespoons of the cheesecake mixture for each ball and roll between your hands until smooth.
Roll each ball in the remaining ½ cup graham cracker crumbs or sugar. Serve immediately or refrigerate for up to 12 hours.
