Use a food processor to finely chop the entire package of cookies. Measure 1.75 cups of cookie crumbs and place them into an electric mixing bowl. Reserve the remaining crumbs in a shallow bowl.
Add powdered sugar to the large bowl of cookie crumbs and mix. Add in the peanut butter and mix well until combined.
Line a baking sheet with wax paper or parchment paper and clear some space for it in the refrigerator.
Use a tablespoon portion scoop to scoop the dough into balls. Roll each ball until smooth using your hands, then roll each ball into the reserved cookie crumbs.
Place the coated balls on the prepared baking sheet and chill in the refrigerator for 1 hour or until firm.
Place the cookie bites into small mini muffin paper liners and serve. Store in the refrigerator until ready to eat.
Notes
These cookie bites are best stored in the refrigerator to maintain their firm texture.
