Preheat oven to 350°F.
In a large bowl, beat butter, brown sugar, sugar, vanilla and salt until smooth and creamy. Gradually add flour until just moistened. Add in milk. Press together to form a ball.
Add dough to the middle of a large cookie sheet. Cover with wax paper and roll lengthwise to form a 12″ by 6″ rectangle. Using a fork, prick dough 1 inch apart. Along the long edge of rectangle, use the fork tines to make a decorative edge on each side.
Bake for 20-25 minutes, or until edges start to brown. Let sit on cookie sheet for 10 minutes and while still warm, cut crosswise into 10-12 bars. Transfer to cooling rack.
Using your favorite frosting recipe, or cookie decorating icing, frost “fingers.” Sprinkle with dried cranberries and pecans.
