Crush the biscoff cookies in a food processor. Or you can place them in a bag and use a rolling pin to bash them till they're finely crushed. Set aside some crushed cookies for decoration.
Place the crushed cookies in a bowl with the cream cheese.
Mix well with the cream cheese until there are no longer white streaks in the mixture. This may take a few minutes.
Take approx. 1 teaspoon heaps and roll into balls.
Place the balls onto a tray and place in the freezer for 30-45 minutes until they are firm.
When the balls are almost frozen. Place the white chocolate into a microwave safe bowl (or glass) and place in the microwave for 30 seconds at a time, mixing in between until melted.
Dip each ball in the white chocolate using a fork. Tap the fork onto the edge of the bowl to remove excess chocolate and place back onto the tray.
Drizzle any leftover chocolate onto the truffles and sprinkle with reserved crushed cookies.
Can be stored in an airtight container for 1-2 days at room temperature or 3-4 days in the fridge. The chocolate may crack in the fridge but shouldn't affect texture or flavour.
