In a food processor, pulse the vanilla wafers into a very fine crumb. Transfer to a mixing bowl. Next, pulse the pecans into a fine crumb and add these to the bowl with the wafers. Pulse the coconut flakes until coarsely chopped and transfer them to a separate shallow dish for later use.

To the bowl containing the pecan and wafer crumbs, add powdered sugar, orange juice concentrate, vanilla extract, and softened unsalted butter. Using a hand mixer, blend all ingredients until the mixture is thoroughly combined and forms a workable dough.

Using a small cookie scoop, portion out the dough and use your hands to roll each portion into a ball.

Roll each formed ball in the coarsely chopped coconut flakes, ensuring an even coating. Place the coated snowballs onto a cookie sheet.

Chill the snowballs in the refrigerator until firm, about 1 hour. Once firm, transfer them to an airtight container for storage. Keep refrigerated to maintain freshness.
