Chocolate chip cookies are a classic dessert and they serve well in the form of a dessert bar. Each bar is so chewy and sweet. The generous amount of chocolate chips makes these bars hard to resist! They are quicker to make since all you have to do is slice and serve instead of scooping dough for each individual cookie. Similar to a skillet cookie!

Why this recipe works

This recipe is a based off my classic chocolate chip cookie recipe. There is a good ratio of brown sugar and butter to keep the cookies sweet and flavorful. The brown sugar and extra egg yolk make the bars extra chewy while the cornstarch makes the bars soft. Chocolate chip cookie bars are perfect when you don’t want to scoop and bake each individual cookie. All you have to do is slice and serve the bars!

Expert tips

Use room temperature ingredients. Not only does it make it easier to combine the ingredients, it also creates a consistent dough and better texture. Most importantly, do not over-bake the bars. The center should be soft and edges set. The bars will continue to bake as they cool.

Frequently Asked Questions

Why are the edges burnt?

If you used a glass baking pan, the edges will bake more quickly since glass retains heat longer.

Why are the cookie bars dry?

They were either baked too long or there was too much flour in the dough. Weigh your ingredients for accurate measuring or fluff up your flour with a fork and spoon it into the measuring cup (don’t pack it in).

How long do chocolate chip cookie bars last?

Cookie bars are best when eaten the day they are baked, but they will last 3 to 4 days in an airtight container at room temperature?

How to freeze chocolate chip cookies bars

The dough may be frozen for up to 3 months. Baked bars may be individually wrapped and frozen in an airtight container for up to 1 month.

Can I make cookies with this dough?

Yes, you can! I personally like chilled the dough first for extra chewy cookies.

Can I make this in a 9×13 pan?

Yes, double the recipe and bake it in a parchment-lined baking sheet. Baking time will be 30 to 35 minutes.
