Finely crush biscoff cookies in a food processor. If you don't have a food processor, add the cookies to a ziplock bag and use a rolling pin to crumble them up.
Add the softened cream cheese, cookie butter, and crushed biscoff cookies to a mixing bowl and combine until you have a dough-like consistency.
Take about 2 tablespoons of the dough and roll into balls. Repeat with the rest of dough.
Pop in the fridge or freezer to chill for about 15 to 30 minutes or until firm.
Melt down white chocolate in the microwave in 30 second intervals on 50% power. Mix in between each interval until completely melted and smooth.
Dip each truffle in the chocolate so it's covered completely and use a fork to let any excess chocolate drip off. Repeat with the rest. Add biscoff cookie crumbs on top if desired as you go along.
Once they're all covered in chocolate, pop in the fridge or freezer for a few minutes just until the chocolate hardens.
After chilling, you can enjoy! Store any leftovers in the fridge.
