Combine the dry ingredients in a bowl: flour, baking soda & baking powder, cinnamon, and salt. Set aside.
Brown the butter: in a saucepan over medium heat, add the butter and stir frequently to keep it moving. It takes about 7-8 minutes to start to brown and smell of the nutty aroma. Once you can smell it and see the toasty amber brown color, remove it from the heat and pour directly into the mixing bowl - still hot.
Add the sugars and mix for a few minutes to cool down. Then add the room temp eggs, one at a time and mix until the batter becomes creamy - about 3 minutes. Scraping the bottom occasionally as it mixes.
Add the vanilla and Rivulet Liqueur, mix to combine.
To the mixer on the lowest speed, add the dry ingredients a little at a time until just barely mixed and some flour streaks remains. Add the chocolate and pecans, then finish mixing by hand with a silicone/rubber spatula.
Wrap the dough tightly and place in the fridge for a 4 hours. If you're in a hurry, 45 minutes in the freezer will suffice.
When ready to bake, preheat the oven to 350 degrees. Line a baking sheet with parchment paper. Scoop out the cookies and press down the tops slightly with additional buttery pecan halves and chocolate chunks.
Bake for 8 minutes. Remove from the oven and leave on the tray to cool for 10 minutes. Sprinkle with finishing salt as they are cooling down.
Store in an airtight container and they will stay fresh for a few days.
