Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. Add the vanilla extract and egg to the mixture and beat well until combined.
¼ cup unsalted butter, ¼ cup granulated sugar, ¼ cup packed light brown sugar, ½ teaspoon vanilla extract, 1 egg
Mix in the flour, baking soda, salt, and cornstarch until soft dough forms. Fold in the mini chocolate chips, ensuring they are evenly distributed throughout the dough.
1 cup all-purpose flour, 2 tablespoon cornstarch, ¼ teaspoon baking soda, ¼ teaspoon salt, ⅓ cup mini chocolate chips
Scoop out small portions of dough, about ½ teaspoon each, and place them on the prepared baking sheet. Leave some space between each cookie as they will spread slightly. Top each cookie with a few extra mini chocolate chips.
