In a small cup, whisk the cornstarch and water together until well combined.
¼ cup (59 ml) water, 2 tablespoon (20 g) cornstarch
In a mixing bowl, whisk the flour, baking soda and salt together until well combined.
2½ cups (300 g) all purpose flour , ¾ teaspoon baking soda, ½ teaspoon salt
In another mixing bowl, beat the butter, brown sugar and granulated sugar until well combined or about 1 -2 minutes on medium speed. Beat in the vanilla extract and cornstarch mixture together until well combined.
1 cup (226 g) unsalted butter, room temperature , 1 cup (200 g) light brown sugar, ½ cup (100 g) granulated sugar, 2 teaspoon (10 ml) vanilla extract
On low, mix in the dry ingredients until just combined. Fold in the chocolate chips.
1 - 2 cups (170 - 340 g) semi sweet chocolate chips
Cover the eggless chewy chocolate chip cookie dough. Transfer the cookie dough to chill in the fridge for at least one hour or up to one week.
Preheat the oven to 375 F (190 C) 30 minutes before baking the cookies. Line a large baking sheet with parchment paper.
Scoop about 2 tablespoons of no egg chocolate chip cookie dough onto the lined baking sheet about 2 - 3 inches apart. I like to use a medium 2 tablespoon (30 ml) sized cookie scoop. Top with more chocolate chips if you like.
Bake the cookies for 12-14 minutes or until the edges are set and are lightly golden brown.
Cool the cookies on the hot baking sheet for 5 - 10 minutes before transferring them to a cooling rack to fully cool to room temperature. Enjoy!
