Crush the Nutter Butter cookies into fine crumbs using a food processor or a zip-top bag with a rolling pin.
In a mixing bowl, combine the crushed cookies, peanut butter, and powdered sugar. Mix until well combined.
Scoop small portions and roll them into 1-inch balls. Place on a lined baking sheet.
Refrigerate the truffles for about 30 minutes until firm.
Melt chocolate chips and coconut oil in the microwave until smooth.
Dip each truffle in the melted chocolate, allowing excess to drip off, and return to the baking sheet.
Add toppings if desired before the chocolate hardens.
Chill the truffles for at least 1 hour to fully set the chocolate.
Notes
Store truffles in an airtight container for up to 3 days at room temperature or up to 1 week in the fridge. They can also be frozen for up to 2 months.
