Step‑by‑Step Instructions for Brown Butter Sheet Pan M&M Chocolate Chip Cookies
Step 1: Brown the Butter
In a medium saucepan, melt 1 cup of unsalted butter over medium heat, stirring frequently. Watch for it to foam and turn golden brown, about 5-7 minutes, releasing a nutty aroma. Once browned, remove from heat and let cool for about 10 minutes to allow the flavors to deepen for your Brown Butter Sheet Pan M&M Chocolate Chip Cookies.
Step 2: Mix Wet Ingredients
In a large mixing bowl, combine the cooled brown butter with ½ cup brown sugar and ½ cup granulated sugar, stirring until smooth and creamy. Add 1 large egg, 1 extra yolk, and 2 teaspoons of vanilla extract, mixing until the ingredients are fully incorporated and fluffy. This creamy base will create a deliciously rich texture for your cookie bars.
Step 3: Mix Dry Ingredients
In a separate bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking soda, 1 teaspoon of baking powder, ½ teaspoon of cornstarch, and a pinch of salt. The dry mixture helps provide structure and goodness to your Brown Butter Sheet Pan M&M Chocolate Chip Cookies. Ensure it’s well combined, with no lumps, to achieve a consistent cookie dough.
Step 4: Combine Mixtures
Gently fold the dry mixture into the wet ingredients, being careful not to overmix. Stop when you see just a few streaks of flour remaining, ensuring your cookie bars remain tender. Next, add in 1 cup of M&Ms and 1 cup of chocolate chips, folding them into the dough until evenly distributed for that irresistible flavor in your cookies.
Step 5: Prepare for Baking
Preheat your oven to 350°F (175°C) and line a quarter sheet pan with parchment paper. Transfer the cookie dough into the prepared pan, using a spatula to spread it evenly to the edges. The sheet pan method makes it easy to enjoy delicious Brown Butter M&M Chocolate Chip Cookies without the fuss of scooping individual cookies.
Step 6: Bake
Place the sheet pan in the preheated oven and bake for 18-22 minutes, or until the edges are golden brown while the center remains soft. Keep an eye on them as they bake, as visual cues are essential for achieving that perfect chewy texture in your cookie bars.
Step 7: Cool and Serve
Once baked, remove the pan from the oven and allow the cookies to cool in the pan for about 10 minutes. Then, lift them out using the parchment paper to cool completely on a wire rack. Once cooled, slice into squares and serve these delightful Brown Butter Sheet Pan M&M Chocolate Chip Cookies to share with family and friends.

Expert Tips for Brown Butter Sheet Pan M&M Chocolate Chip Cookies

- Check for Freshness: Ensure your baking soda and powder are fresh before use to guarantee the perfect rise in your cookie bars.

Brown Butter Sheet Pan M&M Chocolate Chip Cookies Recipe FAQs
How do I choose the right butter for this recipe?
Absolutely! For the best flavor, use unsalted butter. Browning it adds a rich, nutty taste that enhances your Brown Butter Sheet Pan M&M Chocolate Chip Cookies. Unsalted butter also allows you to control the saltiness of your final cookie bars.
What’s the best way to store these cookies?
I recommend storing your cookie bars in an airtight container at room temperature for up to 5 days. This keeps them soft and chewy for snacking throughout the week! If you need them to last longer, you can refrigerate them in an airtight container for up to 7 days.
Can I freeze these cookies?
Absolutely! To freeze your Brown Butter Sheet Pan M&M Chocolate Chip Cookies, first, cut them into squares and lay them out in a single layer on a baking sheet. After that, freeze them until solid for about an hour. Then, transfer to a freezer-safe bag, where they can be stored for up to 3 months. To enjoy, simply thaw at room temperature or reheat in the microwave for about 10-15 seconds.
What should I do if my cookie dough seems too dry?
If your dough feels overly dry, it could be due to too much flour being added. Make sure to spoon and level your flour when measuring for accuracy. If the dough still appears dry, try adding a tablespoon of milk to loosen it slightly. Remember, the dough should be soft but not sticky!
Are these cookies suitable for people with allergies?
Very! These Brown Butter Sheet Pan M&M Chocolate Chip Cookies contain common allergens such as dairy and eggs. For egg-free, you can replace the egg and egg yolk with 2 tablespoons of flaxseed meal mixed with 6 tablespoons of water—let it sit for 5 minutes to thicken. Additionally, feel free to swap out M&Ms for allergy-friendly chocolate or candy options that suit dietary needs.
How long do I need to bake the cookies for the best texture?
To achieve perfect texture, I suggest baking them at 350°F (175°C) for 18-22 minutes. You want the edges to be golden brown but the center to remain soft, which will ensure a delightful chewy bite. Keep a close eye in those final minutes to avoid overbaking!
