Finely crush the biscuits either by using a food processor or by placing them in a bowl and using a rolling pin until they form a fine crumb.
Keep 1 tbsp of the biscuit crumbs and set aside.
Combine the softened cream cheese with the remaining biscuit crumbs in the food processor, pulsing until a thick paste forms. Alternatively, mix thoroughly in a bowl until well combined.
After mixing, use a melon baller or two teaspoons to portion the truffle mixture, rolling each portion into a ball shape.
Arrange the truffles on a lined tray or plate, then place them in the freezer for 30 minutes to set.
After chilling, smoothly melt the white chocolate in a bowl.
Melt the Biscoff spread in a separate small bowl. Prepare the reserved Biscoff crumbs from earlier.
Gently dip each truffle into the melted white chocolate, ensuring a full coating, then transfer them to a clean lined tray. Drizzle a bit of Biscoff spread and sprinkle a few crumbs over the truffles for an added touch.
Continue the process until all truffles are beautifully decorated.
Chill the truffles for about an hour until fully set, then savour and indulge in these delicious treats!
