Heat oven to 350 degrees. Line an 8-inch by 8-inch metal baking pan with aluminum foil or parchment paper.
In a medium bowl, stir melted butter and brown sugar until blended. Add the egg, vanilla extract, maple extract and salt Stir vigorously until smooth.
When the batter looks well blended, add the flour and stir, then beat with a wooden spoon for 40 to 50 strokes. (The batter will be thick).
Fold in the maple chips and pecans. Spread the batter evenly into lined pan and bake 20 to 25 minutes and the edges look browned, but the middle looks slightly underdone (the middle will continue to cook while it cools). Place the pan on a wire rack and let the blondies cool in the pan. Cut into 16 squares.
*I have made this recipe many times, and the blondies have turned out every time*
