In a small saucepan, melt butter and frozen orange juice concentrate, stiring until orange juice is completely dissolved. Then add vanilla extract.
Put crushed vanilla wafer cookies in a medium mixing bowl and pour melted butter mixture over the crushed cookies. Add 1 cup of powdered sugar. Thoroughly mix and then let cool for a few minutes.
Once mixture is cooled, roll cookie mixture into one-inch balls. Combine coconut and 1 cup of powdered sugar and roll cookies into sugar mixture until well coated. Place in air-tight storage container.
