Step 1

Crush vanilla wafers well. (I prefer to use a food processor here.)

Step 2

In a large bowl, combine crushed wafers, condensed milk, and pecans. Mix well to combine. This takes some work. I usually start with a big wooden spoon, but then use my hands.

Step 3

Divide the mixture evenly and press to form into two logs. Wrap each in wax paper and refrigerate for at least 2 hours to firm up.

Step 4

Slice and serve chilled.
