• Preheat oven to 350°F, and line a baking sheet or sheets with a sheet of parchment paper.
• In a medium bowl, whisk together the 1 1/4 cups flour, 3/4 cup cornmeal, 1 1/2 teaspoons cornstarch, 3/4 teaspoon baking powder, 1/2 teaspoon baking soda, 1/2 teaspoon kosher salt.
• In a mixing bowl, cream the 1/2 cup butter with the 2 ounces cream cheese until smooth and well combined. Scrape down the sides and bottom of the bowl, and add the 1 cup brown sugar and 1/2 cup granulated sugar. Beat until fluffy, about 3 minutes. Add the egg, egg yolk, 1 tablespoon of milk, and 1 teaspoon vanilla extract. Mix until well combined. Scrape down the sides and bottom of the bowl.
• Gradually add the dry ingredients and mix until just combined.
• Using a #40 cookie scoop or two tablespoons of dough, place dough about 2 inches apart on the cookie sheet, as the cookies will spread as they bake.

To Finish

• In a small bowl, mix together the 1 tablespoon of sugar and 1 tablespoon of cornmeal. Butter the bottom of a heavy drinking glass, and dip it into the sugar mixture. Gently press the glass down onto each ball of dough to slightly flatten. Sprinkle the cookies with the remainder of the mixture, so that each of the tops are covered.
• Bake for 13-15 minutes until slightly golden. Upon removing from the oven, sprinkle each cookie with some Maldon salt and allow to sit on the cookie sheet for a couple minutes before removing to a wire rack. Please don't skip the Maldon salt, it really brings out more of the flavor of the cookie! Trust me on this.
