Start by preheating your oven to the appropriate temperature.
In a mixing bowl, combine the fine cornmeal, brown sugar, white sugar, baking soda, and sea salt.
Melt the butter until it turns brown and has a nutty aroma, then let it cool slightly.
Add the melted brown butter and vanilla to the dry ingredients, mixing until well combined.
Scoop the dough onto a baking sheet lined with parchment paper, spacing them evenly.
Bake in the preheated oven until the cookies are golden brown.
Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack.
