Place all but one of the Biscoff cookies into a food processor and pulse on high until you have a fine crumb. Add Neufchatel cream cheese and pulse until there's a smooth, evenly combined dough.
Use a tablespoon to scoop balls of truffle dough, then roll in-between clean hands. Place on a parchment paper covered plate and let chill in the fridge while you melt the chocolate.
Add white chocolate chips and coconut oil to a small, microwave-safe bowl. Melt in 30 second intervals, stirring in between each round until all the chocolate chips have melted.
Dip each truffle into the melted chocolate, one at a time. Remove it from the melted chocolate with a fork, and gently tap your wrist with your other hand to help shake off the excess chocolate. Transfer back to the parchment paper covered plate. Crumble the remaining cookie, and sprinkle a few Biscoff cookie crumbs on top of the truffle before the white chocolate has hardened. Repeat until all truffles are dipped.
Refrigerate for 20 minutes, or until set. Transfer to an airtight container and store in the refrigerator for up to 5 days. Enjoy!
