Line a baking sheet with parchment paper.
Place cookies in a food processor and process until cookies are fine crumbs.
Add cream cheese to the cookie crumbs. Mix with a silicone spatula until a dough forms.
Roll the dough into balls, about one tablespoon per truffle.
Freeze the truffles for at least 15 minutes.
Place the semi-sweet chocolate chips and 6 teaspoons of coconut oil into a heatproof bowl. Microwave for a minute at half power, then stir.
Continue heating the chocolate in thirty-second increments until it is smooth.
Add the mint extract and stir.
Place truffle balls into melted chocolate one at a time. Use a fork so excess chocolate can drip off.
Add the white chocolate chips and 2 teaspoons of coconut oil each to their own heatproof bowl. Microwave for a minute at half power.
Continue heating the white chocolate and coconut oil each in their own bowls in thirty-second increments until smooth.
Add 6 drops of green food coloring to the melted coconut oil and mix well.
Pour the coconut oil into the melted white chocolate and mix.
Pour green chocolate in a zip-top bag. Snip the corner of the bag with scissors, then drizzle green-colored chocolate over truffle balls.
Place the pan in the freezer for 15 minutes to fully harden the chocolate.
