Step-by-Step Recipe Guide
Step 1: Preparing the Brown Butter
- Melt the butter in a pan over medium heat.
- Stir continuously until it turns golden brown and smells nutty (about 5 minutes).
- Remove from heat immediately and let it cool slightly.
Step 2: Mixing the Dough
- In a bowl, whisk the brown butter with sugars until smooth.
- Add eggs and vanilla, mixing until fully incorporated.
- In another bowl, combine flour, baking soda, and salt.
- Slowly add the dry ingredients to the wet mixture.
- Fold in chocolate chips and any additional mix-ins.
Step 3: Baking the Bars
- Preheat oven to 350°F (175°C).
- Line a 9×13-inch baking pan with parchment paper.
- Spread the dough evenly in the pan.
- Bake for 22-25 minutes until the edges are golden but the center is slightly soft.

Tips for Success

- Chill the Dough (Optional) – If you want even chewier bars, chill the dough for 30 minutes before baking.
