In a large bowl, mix crushed vanilla wafers, sweetened condensed milk, and chopped pecans using a sturdy wooden spoon or your hands until they are well combined, creating a sticky mixture.

Divide the mixture in half and shape each portion into a log on a piece of wax paper. Aim for a size that fits comfortably on your serving platter.

Wrap each log tightly in wax paper and refrigerate for at least 2 hours, or until they firm up.

Once chilled and firm, remove the logs from the fridge. Slice them into your desired thickness and serve on a festive platter.
