Ingredients Notes
Here are a few staple ingredients used in this recipe. Full details and measurements are in the recipe card below.
All-purpose flour – Standard all-purpose flour works best here. Any other flour won’t work.
Butter – I always use unsalted for baking. Make sure it is cooled back down to room temperature. If it is too warm, the cookie bar batter will be too runny.
Brown sugar – I used light brown sugar. Dark brown sugar works as well.
Chocolate – I used semi-sweet chocolate chips and mini chocolate chips. You can use one or the other, I just personally prefer using both. You can also use a chopped up milk and dark chocolate bars.
Eggs - Make sure it is at room temperature before beginning.
Vanilla - Use high quality vanilla.
Step by step instructions
Here is how to make and bake these chocolate chip cookie bars. You will need an 8×8 square pan lined with parchment paper, a large mixing bowl, a spatula, and a whisk.
Step 1 – Prep. Grease the pan. For easy removal of the brownies, place parchment paper on the bottom and 2 sides of the pan. Grease again and then set aside.
Step 2 – Whisk wet ingredients. In a large bowl, whisk butter, brown sugar, and white sugar. Then whisk in egg, yolk, and vanilla.
Step 3 – Add in dry ingredients. Toss in flour, baking powder, and salt. Mix until no dry streaks appear. This will be a runny batter.
Step 4 – Add chocolate. Toss in chocolate chips and mix in a few more times.
Step 5 – Transfer and bake. Place the batter into the prepared pan and spread evenly. Add with a sprinkle of extra chocolate if desired. Bake for 22-26 minutes or until the top is a light golden brown.
Let the cookie bars cool down completely, slice, and enjoy!
Expert Baking Tips
Here are a few baking tips from my kitchen to yours!
- Use high-quality chocolate chips. These ones are my favourite.
- Use a gram scale. I cannot emphasize this enough! It is the most accurate way of measuring your ingredients in the kitchen. This is one of my favourites.
- These cookie bars should be slightly underdone when finished baking. They will continue baking as they cool in the hot pan.
FAQ
Can I bake these in a different pan?
Yes, you can bake them in an 9x9 pan but they will be thinner.
Can I brown the butter?
Yes, if you want to elevate these cookie bars and take them to the next level, brown the butter.
Why don't you chill the cookie dough?
This cookie dough is placed and baked in a pan, so it doesn't have any space to spread like it would if it was scooped into cookies on a cookie sheet. So there's no need to chill the dough!
Can I scoop these into cookies?
I haven't tried using this dough in cookie form so I can't say. If you want to make cookies, try baking Classic Chocolate Chip Cookies instead.

For 3 times as much what size pan? A jelly roll pan or 10 x 15?
