Place ground cookies in a bowl, stir in coca-cola and set aside for 5 minutes.
Add melted chocolate and melted butter and mix well.
Cover the bowl and leave in the fridge for half an hour.
Roll 1 inch balls and place them on parchment paper. Freeze them at least half an hour.
Melt 10 oz of white chocolate and drop frozen balls in the melted chocolate, and using a fork transfer them onto parchment paper(gently tap off excess chocolate), then put them back in the freezer for 10 minutes.
Melt the rest of the white chocolate, transfer it in the ziploc bag, cut the corner and drizzle onto truffles.
