Place the Biscoff cookies in a food processor and blend into fine crumbs. Reserve about 1–2 tbsp of crumbs for garnishing, if desired.
In a mixing bowl, combine the crushed cookies, softened cream cheese, and Biscoff spread.
Mix thoroughly until the ingredients are fully combined and form a dough-like consistency.
Using your hands or a small cookie scoop, roll the mixture into bite-sized balls (about 1 tablespoon each).
Place the truffle balls on a baking tray lined with parchment paper.
Chill in the freezer for 30 minutes to firm up.
Melt the white chocolate in a microwave or over a double boiler until smooth. Then add in the Biscoff spread.
Dip each truffle into the melted white chocolate, ensuring it’s fully coated. Use a fork to lift the truffle out and let excess chocolate drip off.
Place the coated truffles back on the parchment-lined tray.
While the chocolate is still wet, sprinkle the reserved crushed Biscoff cookies on top of each truffle.
For extra decoration, drizzle melted Biscoff spread over the truffles (optional).
Refrigerate the truffles for another 30 minutes or until the chocolate coating is set.
Serve chilled or at room temperature.
