Combine in a large mixing bowl, the softened butter, maple syrup, vanilla, and powdered sugar. Use a hand blender to cream the butter until light and fluffy.
1 cup Unsalted Butter, ¼ cup Maple Syrup, ⅓ cup Powdered Sugar, 1 teaspoon Vanilla Paste
Add to the creamed butter mixture, the flour, salt, and toasted pecan pieces. Make sure that the toasted pecan pieces are fully cooled before adding to the batter. Blend until batter comes together.
2 cups All Purpose Flour, ¼ teaspoon Salt, ¾ cup Pecan Pieces
Divide the batter into 2 portions. Use your hands to give 1 portion an initial log shape which should be about 10 inches in length. Place it on a piece of parchment paper.
Wrap the parchment paper over the log of dough. Use a bench scraper tuck the overlapping piece of parchment, under the log, all-the-while holding down the bottom portion of the parchment. This will wedge the log in the parchment and tighten it, giving it a round shape.
Wrap the rounded log of shortbread dough in the parchment paper. Repeat with the 2nd portion of the dough. Refrigerate the 2 shaped logs for at least 1 hour. Wrap 1 of the logs of dough in parchment paper and freeze if only baking half of the dough.
Preheat the oven to 325F and line a baking sheet pan with parchment paper. Unwrap the chilled log of dough and place on a cutting board. Cut into ½ inch slices.
Place on the sheet pan and bake for 20-25 minutes of until the edges are lightly golden. Remove the baked Maple Pecan Shortbread Cookies from the oven and let them cool completely before serving.
