Preheat oven to 350.
Remove the phyllo cups from the plastic trays in the boxes and place them directly on a large baking pan lined with a silicone mat.
Mix together the sugar, corn syrup, pecans, egg, melted butter, vanilla and salt.
Spoon a small amount of the the pecan mixture in to each cup, making sure you get plenty of pecans in each one.
Bake at 350 degrees for 10-12 minutes or until just starting to bubble.
Remove from the oven, let them sit on the tray for just a couple of minutes then carefully transfer to a cooling rack. (These babies will burn your mouth if you try to eat them right out of the oven.)
