1. Preheat the oven to 350°F (180°C). Line a baking sheet with baking parchment and set it aside. Chop the pecans and set aside.

2. Add the butter and sugar (or xylitol) to a large bowl and mix until light and fluffy. Add the eggs separately and mix well after each addition. Add the maple syrup and vanilla extract and stir in. Mix the flour with the rolled oats, baking powder, cinnamon, and salt. Add to the bowl and mix until just combined. Add the chopped pecans and fold them in. Use a cookie scoop* and place dough portions with enough space in between on the prepared baking sheet, flatten them slightly, press a whole pecan into the dough (optional, and then bake for 13-14 minutes. The edges of the cookies should have set with a bit of color. Take out of the oven and let cool down on the baking sheet for a moment, then transfer to a wire rack to cool down completely. If you could not fit all of the cookies on one baking sheet, repeat with the remaining dough.
