Combine dry ingredients: In a separate bowl, whisk 2 ¾ cups unbleached all-purpose flour, ½ teaspoon table or sea salt, 1 teaspoon baking powder, ½ teaspoon soda, and 2 teaspoons cinnamon.

Bake: Cook 10–12 minutes or until set. Cool on a wire rack.
Make browned butter icing: Brown 2-3 tablespoons butter (the real thing) in a small skillet. (This may take several minutes on low heat—be careful not to burn it or you have to start over.) Stir in 2 cups powdered sugar and 1 tablespoon milk until smooth, adjusting consistency with more sugar or milk if needed.
Frost cookies: Spread icing over slightly warm cookies and sprinkle with chopped, toasted pecans.
