These gluten-free chocolate chip cookie bars are buttery, filled with chocolate chips, and easy to make. They’re basically your favorite chocolate chip cookie in a thick, easy-to-make bar!
Preheat oven to 350℉. Spray a 9x13 pan with nonstick cooking spray.
Mix together softened butter, brown sugar, and granulated sugar until thick, about 30 seconds.
Add eggs and vanilla extract. Mix until fluffy.
Add the gluten-free flour, baking soda, and salt. Mix until a thick batter forms. Stir in chocolate chips.
Spread the batter evenly into the prepared pan.
Bake until light golden brown. A cake tester inserted into the center of the pan should come out clean, about 30 minutes.
Cool bars in the pan. Cut into 12 bars.
To store: wrap tightly and keep at room temperature for up to four days or freeze for up to 4 months.
Dairy-free variation. Replace the butter with a dairy-free buttery spread that's suitable for baking. Use dairy-free chocolate chips.
