For the cookies: In a mixing bowl whisk together flour and salt. In the bowl of an electric stand mixer fitted with the paddle attachment, mix together butter and sugar until well combined.
Spread glaze over cooled cookies and immediately top with sprinkles or pecans if using after icing each cookie (glaze will begin to set quickly).
*Note that some maple extracts have more coloring in them than others so your glaze may not be quite as dark as that pictured. I tested with two different brands, Mapleine and Watkins. While both are good I like the Watkins better for flavor as it seems to have a bit more of a maple flavor, but the Mapleine does have more of that classic maple glazed doughnut color.
