Preheat oven to 350°F. Prepare a baking sheet with a silicone liner or parchment paper. Set aside.
Using a hand-held mixer, blend together the brown sugar and butter until light and fluffy.
Add the egg and salt. Mix into the butter mixture.
Add the flour, baking soda, and cinnamon. Mix until just incorporated. Do not over mix.
Stir in one cup of the cinnamon chips.
Use a small cookie scoop, about 1 tablespoon in size, to scoop the cookie batter into even portions. Roll into balls and place on prepared baking sheet, at least 1 inch apart. Top with a few extra cinnamon chips if desired.
Bake for 15 minutes. Remove from oven and immediately transfer to a wire cooling rack to completely cool.
Once completely cooled, dust with confectioner's sugar, if desired.
