Preheat the oven to 350°F (175°C).

In a large mixing bowl, beat the softened butter and honey together until creamy and smooth, about 2-3 minutes.

Add the egg and vanilla extract to the mixture and mix until well combined.

In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon (if using).

Gradually add the dry ingredients to the wet mixture, mixing until just combined.

Using a spoon or cookie scoop, drop rounded tablespoons of cookie dough onto a lined baking sheet, leaving space for spreading.

Sprinkle a light pinch of sea salt on top of each cookie.

Bake in the preheated oven for about 10-12 minutes or until the edges are slightly golden.

Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
