- 2 2/3 cups all purpose flour (gives structure and texture)

- 1 tsp. baking soda (helps cookies rise)

How to Make Brown Butter Chocolate Chunk Cookies
Step 1. Start by preheating your oven to 350°F. Line two baking sheets with parchment paper to prevent sticking and ensure easy cleanup. This will create a non-stick surface for the cookies to bake evenly, allowing them to achieve that desired golden exterior.
Step 2. In a glass bowl, add the cut pieces of unsalted butter. Place the bowl in the microwave or over low heat to brown the butter gently. Watch for the butter to melt and turn a golden-brown color, which will develop a nutty aroma. Once it has cooled slightly, it’s ready for the next step.
Step 3. Using a hand mixer, beat the packed dark brown sugar and granulated sugar into the slightly cooled brown butter. This process will create a creamy mixture, incorporating air for a light texture. Look for the sugars to dissolve fully, resulting in a smooth consistency.
Step 4. To the mixture, add the large egg, large egg yolk, milk, and vanilla extract. Beat again until all ingredients are well combined and creamy. The batter should appear smooth and cohesive, indicating that all elements are properly mixed.
Step 5. Sift the dry ingredients—flour, salt, baking soda, and baking powder—into the bowl. Carefully fold these dry ingredients into the mixture until just combined. Avoid over-mixing to maintain a tender cookie texture. The dough should look slightly thick and well blended.
Step 6. Gently fold in 3/4 cup of the chocolate chunks. This will disperse the chocolate throughout the dough, giving each cookie delightful bites of chocolate. Ensure that the chunks are evenly distributed but without overworking the dough.
Step 7. Scoop the dough to form balls, and dunk each one in the remaining chocolate chunks, pressing lightly to adhere. Place the dough balls spaced out on the prepared baking sheets. This spacing will allow for spreading during baking, ensuring they don’t stick together.
Step 8. Bake the cookies for 10-11 minutes, or until the edges are light golden brown. Keep an eye on them, as they will continue to cook slightly even after being removed from the oven. The center may look soft, which is perfectly normal for chewy cookies.
Step 9. Once baked, let the cookies rest on the baking sheet for 2-3 minutes. This brief resting period allows the cookies to set, making them easier to transfer to a cooling rack. If desired, sprinkle with flaky sea salt at this stage for an extra touch of flavor.

Serving Suggestions
These Brown Butter Chocolate Chunk Cookies make a great treat any time of day. They can be enjoyed warm for breakfast alongside your morning coffee, or as a satisfying snack after school or work. If you’re hosting a casual family meal, they pair well with vanilla ice cream or fresh fruit for dessert. Leftover cookies can be stored for later, making them an easy go-to treat for unexpected guests or late-night cravings.
Pro Tips for Best Results
- Chill the dough: If you have time, chilling the dough for 30 minutes can enhance flavor and prevent spreading.
- Don’t overmix: When incorporating dry ingredients, mix just until combined to keep the cookies tender.
- Watch baking time closely: Ovens can vary, so monitor them toward the end to avoid over-baking.
- Use quality chocolate: Good chocolate enhances flavor; choose your favorite semi-sweet chocolate.
- Experiment with sea salt: Adjust the amount of flaky sea salt on top according to your taste preference for a balanced finish.
Common Mistakes to Avoid
- Not browning the butter properly: If the butter burns, it will impart an unpleasant taste. Watch closely and remove it as soon as it turns golden brown.
- Using chilled eggs: Cold eggs can cause the mixture to curdle and separate. Always use room-temperature eggs for uniform mixing.
- Skipping the sifting step: Not sifting flour can lead to clumps in your dough and uneven texture. Always sift to ensure a smooth batter.
- Over-baking cookies: If baked too long, cookies can become hard instead of chewy. Keep an eye on them, as they’ll firm up while cooling.
- Not allowing cookies to cool on the sheet: Transferring them too soon can cause breakage. Let them rest for a couple of minutes first.
- Using too much flour: Packing flour can lead to dry cookies. Scoop the flour gently into the measuring cup and level it off without packing.
Variations & Substitutions
Try adding chopped nuts for added crunch or using different types of chocolate, such as dark or milk chocolate, for a unique flavor. You can also swap in a combination of chocolate and nut butter for a richer taste. If you’re feeling adventurous, consider incorporating spices or extracts like almond or espresso for a twist on the classic flavor profile.
Storage & Reheating
Store these cookies at room temperature in an airtight container for up to five days to maintain their freshness. If you want to keep them longer, you can refrigerate them for up to two weeks. For freezing, place the cookies in a single layer in a zip-top bag, pressing out the air before sealing. To reheat, pop them in a microwave for about 10-15 seconds to refresh their chewy texture.
