Heat the oven to 350°F.
In a large bowl, stir the brown sugar, butter, baking soda, cinnamon, vanilla, salt and eggs with a wooden spoon until well mixed.
Stir in the oats, flour and raisins until mixed.
For each cookie, scoop a rounded tablespoonful of dough, using a tableware spoon, and push it onto an ungreased cookie sheet with another spoon or rubber spatula, placing cookies 2 inches apart.
Bake 9 to 11 minutes or until light brown. Remove cookies from cookie sheets to a cooling rack, using a turner. Cool cookie sheets 10 minutes between batches.
