Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a medium bowl, whisk together the flour, baking soda, salt, and cinnamon. Set aside.
In a large bowl, cream the softened butter, granulated sugar, and brown sugar together until light and fluffy.
Beat in the honey, egg, and vanilla extract until well combined.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Stir in the rolled oats and chopped nuts if using.
Drop tablespoon-sized balls of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake for 10-12 minutes or until the edges are lightly golden.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
