Preheat oven to 350 degrees.
Place the butter into a bowl or use a stand mixer and mix it well until it has been creamed or smooth.
Add the sugar, mix again. Then add the flour, salt, baking powder, vanilla extract, maple extract and chopped pecans, mix until well incorporated.
This dough will be thick and very easy to handle.
I sprinkle powdered sugar out on the board I roll the dough, to prevent sticking since this is a cookie. Roll dough flat, to about 1/4" in thickness and either cut into pieces with a knife or use a cookie cutter to cut into shapes. Place cookies on baking pan and place in the oven.
Bake for approximately 10-12 minutes or until the edges are just very lightly golden. Let sit on the baking pan for a few minutes, then carefully transfer to a wire, cooling rack to complete their cooling.
