꒰ 2/4 cups of all purpose flour. 1 teaspoon of baking soda. 1 and 1/2 teaspoons of cornstatch. 1/2 teaspoon of salt. 3/4 cup unsalted butter, melted & cooled for 5 minutes. 3/4 cup of packed light or dark brown sugar. 1/2 cup of granulated sugar. 1 large egg and 1 egg yolk and room temperature. 2 teaspoons pure vanilla extract. 1 and 1/4 cups of semi-sweet chocolate chips or chocolate chunks. ꒱
whisk the flour bakind soda, cornstarch, and salt together in a large bow. And then set aside ♡
In a medium sized bowl, whisk the melted butter, brown sugar, and granulated sugar together until no brown sugar lumps remain. Whisk in the egg and egg yolk. Finally, whisk in the vanilla extract. The mixture will be thin. Pour it into the dry ingredients and mix it together with a large spoon or rubber spatula. The dough will be very soft, thick, and appear greasy. Fold in the chocolate chips. The chocolate chips may not stick to the dough because of the melted butter, but do your best to combine them.
Cover the dough tightly and chill in the refrigerator for at least 2-3 hours or up to 3 days. I highly recommend chilling the cookie dough overnight for less spreading.
take the dough out of the refrigerator and allow it to slightly soften at room temperature for 10 minutes.
preheat oven to 325 degrees fahreinheit. Line large baking sheets with parchment paper or silicone baking mats. set aside.
using a cookie scoop or tablespoon measuring spoon, measure 3 scant tablespoons of dough for xl cookies or 2 heaping tablespoons of dough for medium/large cookies. roll it into a ball, making sure the shape is taller rather than wide-almost like a cylinder. this helps the cookies bake up thicker. repeat with remaining dough. place 8-9 balls dough onto each cookie sheet.
bake the cookies for 12-13 minutes or until the edges are very lightly browned (xl cookies can take closer to 14 minutes). the centers will look very soft, but the cookies will continue to set as they cool. cool on the baking sheet for 10 minutes. meanwhile, press a few extra chocolate chips into the tops of the warm cookies. this is optional and only for looks. after 10 minutes of cooling on the baking sheets, transfer the cookies to a wire rack to cool completely.
cookies stay fresh covered at room temperature for up to 1 week.
