With a standing mixer or handheld mixer, beat butter until light and fluffy, about 30 seconds.
Add in granulated sugar, brown sugar, maple syrup, baking soda, cream of tartar, and salt. Beat until well combined, making sure to scrape down the sides of the bowl as needed.
Next, add in the egg and the egg yolk. Beat until well combined.
Add in the vanilla extract and almond extract, mixing until well combined.
Lastly, add in the flour, about 1/2 cup at a time. Mix until all flour is incorporated into the dough.
Chill dough for 30 minutes to 1 hour.
Once the dough has chilled, preheat the oven to 325 degrees and line a large baking sheet with parchment paper.
Roll dough into about 1” balls, and roll in cinnamon sugar.
Place dough on the baking sheets, making sure they are spaced out evenly, about 2-3” apart (these cookies expand).
Bake for about 12-14 minutes, or until the edges are slightly brown. Allow cookies to cool a few minutes before removing them from the tray and allowing them to cool completely on a wire rack.
