In a mixing bowl, combine the crushed ginger snap cookies, softened cream cheese, powdered sugar, ground ginger, ground cinnamon, nutmeg, and allspice. Mix until fully incorporated and a dough-like consistency forms.
Using your hands, pinch off small portions of the cookie mixture and roll them into balls, about 1 inch in diameter. Place the truffles onto a baking sheet lined with parchment paper.
Once all the truffles are rolled, place them in the freezer for about 15 minutes to firm up.
While the truffles are chilling, melt the dark chocolate chips in a microwave-safe bowl in 30-second intervals until smooth, stirring between each interval to avoid burning.
Dip each chilled truffle into the melted chocolate, using a fork to ensure they are evenly coated. Place them back onto the parchment-lined baking sheet.
If desired, melt the white chocolate chips and drizzle them over the coated truffles for an extra touch.
Sprinkle a tiny pinch of sea salt on top of each truffle for a contrast in flavor.
Place the truffles back in the fridge to set for about 30 minutes before serving.
Notes
Serve the truffles in decorative mini cupcake liners on a festive platter, and garnish with a sprinkle of extra crushed ginger snaps for added texture and visual appeal.
