Instructions

In a large frying pan over medium heat, melt the butter. Once it is melted, stir occasionally until the milk solids separate and turn amber in color. The butter will first become really bubbly, then it will turn foamy. Once it foams up, stir and keep a close eye for the milk solids to turn amber in color!
3/4 cup Plus 1 TBSP Unsalted butter
Pour the hot browned butter into a liquid measuring cup. It will equal to exactly 3/4th cup. Place the butter in the fridge while you prep the rest of the bars.
Preheat the oven to 350℉. Spray a 9X9-inch baking pan with nonstick baking spray. Line the bottom and 2 sides of the pan with parchment paper and spray again.
In a medium bowl, mix the flour, baking soda, and salt. Set aside.
1 3/4 cups All-purpose flour, 1/2 tsp Baking soda, 1/2 tsp Salt
In a large bowl, add the brown sugar, sugar, and browned butter and whisk until combined.
3/4 cup Brown sugar, 1/3 cup White granulated sugar
Add in the vanilla and cold eggs and whisk until smooth. The cold eggs will cool the butter down.
1 tsp Pure vanilla extract, 2 Large eggs
Add in the dry ingredients and switch to a baking rubber spatula and mix until combined. Add in the chocolate chips and the mini chocolate chips and mix. It will be a runny batter.
1 cup Semi-sweet chocolate chips, 1/3 cup Mini chocolate chips
Pour and spread the cookie dough into the pan. Spread it evenly. Add a sprinkle of chocolate chips and mini chocolate chips to the top and lightly press them in.
Bake for 27-30 minutes. Bake until the top is golden brown.
Let the cookie bars cool completely in the pan before taking them out to serve.

Notes

Flour- Make sure flour is spooned and leveled or use a kitchen scale. Compacted flour can dry out the bars and make them cakey.

High altitude baking- Add an extra 1 TBSP of flour.
