In a small bowl or glass jar, add the mixed nuts and bourbon. Cover with lid or plastic wrap and let sit overnight.
Combine the butter, sugar, and vanilla until sugar is dissolved. Add in the crushed graham crackers, vanilla, chocolate chips, walnuts, and remaining bourbon.
Freeze for 10-15 minutes or until firm enough to roll.
Form mixture into small balls, and refrigerate.
Coat the balls in melted chocolate and top with walnuts.
Chill for 1 hour.
Enjoy!
