In a small sauce pan, heat your butter on low, stirring constantly until the color of the butter turns a golden brown color and it gives off a nutty aroma.
Immediately transfer the brown butter to a cool bowl or container to stop the cooking so the butter doesn't burn.
Allow the butter to sit until close to room temperature and then place in the fridge for approx 30 minutes, or until the butter is back to it’s solid form.
Once the butter is back to being solid, preheat the oven to 350° F.
In the bowl of a stand mixer, combine the brown butter and granulated sugar until light in color and fluffy in texture.
Scrape the sides of the bowl and add in the egg, canola oil, corn syrup and vanilla extract.
Mix until well combined.
Add in the flour, baking soda and salt.
Mix until a soft dough comes together.Use a cookie scoop to portion out the cookie dough. For small cookies, use 1 1/2 tbsp of dough (#40 scoop) and for larger cookies use 3 tbsp of dough (#24 scoop).
Arrange on a cookie sheet.Bake at 350° F until the cookies spread slightly and expand. For the small cookies, about 7-9 minutes. For the larger cookies, for 9-11 minutes.
Allow the cookies to cool on the cookie sheet for 5 minutes before transferring to a wire cooling rack.
