Ingredients You’ll Need
- 1 cup unsalted butter (to be browned): The base of this recipe. Browning the butter develops a deeper, nuttier flavor. For best results, use high-quality butter.
- 1 ½ cups light brown sugar (loosely packed): Adds a moist texture and rich flavor. Dark brown sugar can be used for a more robust taste.
- 2 eggs (lightly beaten): Provides moisture and binding. Ensure they are at room temperature for better mixing.
- 1 tablespoon vanilla extract: Enhances the sweetness and creates a more complex flavor profile. Use pure vanilla extract for the best taste.
- 2 cups all-purpose flour: The main structure of the bars. You can substitute with a gluten-free blend if needed.
- ½ teaspoon baking soda: Helps the bars rise. Make sure it’s fresh for proper leavening.
- ½ teaspoon salt: Balances the sweetness and enhances the chocolate flavor.
- 1 cup milk chocolate chips: Offers sweetness and creaminess. You could replace these with semi-sweet if you prefer darker chocolate.
- 1 cup dark chocolate chips: Adds depth and richness; feel free to mix types of chocolate based on your preference.
- Maldon flaked salt (for topping): This salt not only adds a delightful crunch but enhances every bite’s flavor.
How to Make Salted Brown Butter Chocolate Chip Cookie Bars
Melt the Butter: Begin by melting 1 cup of unsalted butter in a medium saucepan over medium heat. Stir frequently until it foams and transforms to a beautiful golden brown, releasing a lovely nutty aroma—this should take about 5-7 minutes. It’s a step that makes a significant impact on the flavor!
Mix the Brown Sugar and Butter: In a large mixing bowl, whisk together the 1 ½ cups of loosely packed light brown sugar and the slightly cooled browned butter until you have a smooth mixture. Add the 2 lightly beaten eggs and 1 tablespoon of vanilla extract, mixing until everything is combined well.
Combine Dry Ingredients: In another bowl, whisk together the 2 cups of all-purpose flour, ½ teaspoon of baking soda, and ½ teaspoon of salt. This ensures that the leavening agent is evenly distributed in the flour.
Fold in Chocolate Chips: Gradually add your dry mixture to the wet ingredients, stirring gently until just combined; it’s okay if a few lumps remain! Then carefully fold in 1 cup of milk chocolate chips and 1 cup of dark chocolate chips with a spatula, making sure they’re evenly distributed throughout.
Preheat the Oven: Before moving on, preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper leaving some overhang. Lightly grease the parchment to prevent sticking.
Spread the Batter: Spoon the cookie bar batter evenly into the prepared pan, smoothing out the top with a spatula.
Bake Until Golden: Bake in the preheated oven for 20-25 minutes until the edges turn a lovely golden brown. A toothpick inserted into the center should come out with moist crumbs, signaling that your bars are ready.
Add Flaky Salt: Once out of the oven, sprinkle a generous amount of Maldon flaked salt on top of the warm cookie bars. This final touch enhances the sweetness and adds a savory crunch.
Cool and Slice: Allow the bars to cool in the pan for about 15 minutes. Then, carefully lift them out using the parchment overhang and transfer to a wire rack to cool completely. Cut into squares or rectangles and enjoy!

Storing & Reheating
Store your Salted Brown Butter Chocolate Chip Cookie Bars at room temperature for up to 4 days in an airtight container. If you’d like to keep them longer, refrigerate for up to a week in a similar container. They freeze beautifully, too! Wrap the bars tightly in plastic wrap and place them in a freezer-safe container for up to 3 months. Reheat individual servings in the microwave for about 10-15 seconds to restore their gooeyness, although note that the texture may change slightly after freezing.
Chef’s Helpful Tips
- Make sure to constantly stir the butter while browning to avoid burning.
- For best results, keep your ingredients at room temperature; this helps them combine more smoothly.
- If you prefer thicker cookie bars, use an 8×8-inch pan and increase the baking time slightly.
- Remember to sprinkle the Maldon salt immediately after baking; it clings best to warm bars.
- Experiment with different types of chocolate or add nuts for an extra crunch!

Recipe FAQs
Can I use a different type of chocolate?
Yes! Feel free to mix and match the types of chocolate chips you use. Dark chocolate, semi-sweet, or even white chocolate will work perfectly. Just keep in mind that different chocolates can alter the sweetness of your cookie bars.
Why is my butter burnt?
If your butter turns too dark or smokes while melting, it may be overcooked. Keep a close eye on it and stir continuously to gauge the color change. Remember, you want a golden brown, not dark brown or black.
Can I make these ahead of time?
Absolutely! You can prepare the batter the day before baking. Just cover it and refrigerate. When you’re ready, let it sit at room temperature for a few minutes before spreading and baking.
How do I know when the cookie bars are done?
Check your cookie bars for doneness by inserting a toothpick into the center; it should come out with moist crumbs, not wet batter. Depending on your oven, baking times may vary slightly, so keep an eye on the edges as they start to turn golden!
