How To Make Chocolate Chip Cookie Bars
This is a summary version; for the complete list of ingredients and instructions, please refer to the recipe card below.
- Whisk the flour, baking soda, cornstarch, and salt in a medium bowl.
- In a large bowl, stir the melted butter, brown sugar, and granulated sugar.
- Stir in the eggs and vanilla extract.
- Mix the flour mixture into the sugar mixture in several increments until combined. Fold in the chocolate chips.
- Spread the cookie batter into a parchment paper-lined 9×13-inch dish. Use an offset spatula to even the batter.
- Bake until lightly browned and set.


Preparation Tips For Success
- Line the baking dish with parchment paper to make it easy to remove the lemon bars. For a quick tutorial, watch this video.
- Slice the bars using a sharp knife. For extra-clean cuts, rinse the knife with hot water and dry it between cuts.
- A dough scraper works great for making clean, even, large cuts. Coat the end of it with a little nonstick baking spray.
- Store thoroughly cooled bars in an airtight container on the counter at room temperature for up to 5 days or in the fridge for up to 8 days.
