Directions

• Step 1: Brown the Butter - In a medium saucepan, melt the unsalted butter over medium heat. Continue to cook, stirring frequently until the butter starts to foam and turns a golden brown color, about 5-7 minutes. Be careful not to burn it!
• Step 2: Mix the Wet Ingredients - Remove the pan from heat and let the brown butter cool slightly. In a large mixing bowl, combine the brown butter with the light brown sugar. Whisk until well combined. Add the lightly beaten eggs and vanilla extract, stirring until smooth.
• Step 3: Combine the Dry Ingredients - In another bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually mix the dry ingredients into the wet mixture, stirring until just combined. Be careful not to overmix!
• Step 4: Fold in the Chocolate Chips - Gently fold in the milk chocolate and dark chocolate chips until evenly distributed throughout the dough.
• Step 5: Prepare the Baking Pan - Preheat your oven to 350°F (175°C). Line your 9x13 inch baking pan with parchment paper, allowing some overhang for easy removal later. Spread the cookie dough evenly in the pan, smoothing the top with a spatula.
• Step 6: Bake - Bake in the preheated oven for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out mostly clean.
• Step 7: Add the Finishing Touch - As soon as you take the bars out of the oven, sprinkle the top with Maldon flaked salt for that perfect salty-sweet contrast.
• Step 8: Cool and Slice - Let the bars cool in the pan for about 10-15 minutes before lifting them out using the parchment paper. Transfer to a cooling rack to cool completely. Once cooled, slice into squares and enjoy!
