Crush Biscoff biscuits into fine crumbs and place the crumbs into a large mixing bowl. The easiest method is to blitz the cookies in a food processor, but you could also do this by hand or with a rolling pin.
Add cream cheese to the mixing bowl or food processor and mix together until evenly distributed.
Using a teaspoon or small ice cream scoop, scoop the dough and roll them into balls using the palm of your hands.
Place the balls onto a baking tray lined with parchment paper. Place in the freezer and freeze for 30 minutes.
Once the balls have chilled in the freezer, melt white chocolate in the microwave until melted and runny.
In a separate mixing bowl, melt Biscoff spread in the microwave for a few seconds or until runny. Then place the remaining crushed Biscoff biscuits in a small mixing bowl.
Dip a truffle into the melted white chocolate (make sure it is coated on all sides). Place it onto a clean baking tray, drizzle melted Biscoff spread and sprinkle crushed Biscoff biscuits. Repeat for all Biscoff truffle balls.
Place in the fridge for a minimum of 30 minutes or until the chocolate has hardened and set.
