Ingredients You’ll Need

  • Unsalted Butter: Using unsalted butter lets you control the salt content in your cookies. Browning it is key for that deep, nutty flavor!
  • Light Brown Sugar: This gives our cookies that signature chewiness and adds a wonderful molasses flavor.
  • Granulated Sugar: Balances the sweetness and helps with spread and crisp edges.
  • Large Egg & Egg Yolks: The extra egg yolks are our secret for an extra rich, chewy, and tender cookie!
  • Vanilla Extract: Don’t skip this! It enhances all the other flavors beautifully.
  • All-Purpose Flour: The structure of our cookie. Make sure to measure it correctly!
  • Cornstarch: This is an optional but wonderful addition! It helps make the cookies extra soft and chewy.
  • Baking Powder: Our leavening agent, giving the cookies a nice lift.
  • Fine Grain Salt: Essential for balancing the sweetness and bringing out all the flavors.
  • Crushed Oreos: Adds amazing texture and chocolatey goodness.
  • M&Ms: For a pop of color and extra chocolatey sweetness.
  • Semi-Sweet Chocolate Chips: Classic cookie goodness!
  • Sprinkles: Totally optional, but they add a fun, festive touch!

How to Make Brown Butter Oreo M&M Chip Cookies (Soft, Chewy, Bakery Style) Step by Step

First things first, we’re going to brown our butter. This is where a lot of the magic happens! Just put your unsalted butter in a saucepan over low to medium heat. Keep stirring it constantly, and watch as it melts, then foams, and finally, little golden-brown bits appear at the bottom and your kitchen fills with a wonderful nutty aroma. As soon as it’s golden and smells nutty, take it off the heat immediately so it doesn’t burn. Let it cool down just a bit.

While your butter cools, grab a big bowl. Once it’s slightly cooled, mix that beautiful brown butter with your light brown sugar and granulated sugar. You’ll want to mix it for about two minutes until it’s nice and combined. Then, add in your large egg, two egg yolks, and that lovely vanilla extract. Mix it all up until everything is just combined – don’t overmix!

Now, it’s time for the dry ingredients. Gently fold in your all-purpose flour, the optional cornstarch (I highly recommend it for chewiness!), baking powder, and fine grain salt. Mix until the flour streaks have just disappeared. Be careful not to overmix here, as that can lead to tough cookies. Finally, fold in your crushed Oreos, M&Ms, chocolate chips, and if you’re feeling extra fun, those sprinkles! Once everything is evenly distributed, pop your dough into the fridge for 30 minutes. This chilling step is super important for flavor and texture, trust me!

My Top Tips for Success

  • Brown your butter carefully: Watch it closely! It can go from perfect to burnt in seconds. Remove from heat as soon as it’s golden and smells nutty.
  • Don’t skip chilling the dough: I always chill my dough for at least 30 minutes. It helps the flavors meld and prevents the cookies from spreading too much.
  • Measure flour correctly: Spoon and level your flour, don’t scoop it directly from the bag. Too much flour makes dry cookies.
  • Don’t overmix the dough: Once the flour is added, mix only until just combined. Overmixing develops gluten, leading to tough cookies.
  • Bake until just set: In my experience, cookies are done when the edges are set and lightly golden, but the centers still look a little soft. They’ll continue to bake on the hot pan.
  • Use a cookie scoop: This ensures all your cookies are the same size, which helps them bake evenly.

Common Mistakes to Avoid

  • Over-browning the butter: If it turns too dark, it will taste bitter. Start over if this happens.
  • Not chilling the dough: This will result in flat, overly spread cookies. The chill time is crucial for texture.
  • Overmixing the wet ingredients after adding eggs: This can incorporate too much air, leading to a cakey texture instead of chewy. Mix until just combined.
  • Baking too long: Overbaked cookies will be dry and crumbly. Pull them out when the edges are set and centers are still soft.

How to Store Brown Butter Oreo M&M Chip Cookies (Soft, Chewy, Bakery Style)

  • Room Temperature: Store in an airtight container for up to 3-4 days.
  • Freezer (Baked): Place cooled cookies in a freezer-safe bag or container for up to 3 months. Thaw at room temperature.
  • Freezer (Dough Balls): Scoop dough into balls, place on a baking sheet, and freeze until solid. Transfer to a freezer-safe bag for up to 3 months. Bake from frozen, adding a minute or two to the bake time.

Frequently Asked Questions

Can I use salted butter instead of unsalted?

Yes, you can use salted butter. If you do, omit the ½ teaspoon of fine grain salt from the recipe to avoid overly salty cookies.

What if I don’t have cornstarch?

Cornstarch is optional, but it really helps with the soft and chewy texture. If you don’t have it, your cookies will still be delicious, just a little less soft.

Why do I need to chill the dough?

Chilling the dough allows the butter to solidify, preventing the cookies from spreading too much. It also deepens the flavors, resulting in a richer, chewier cookie.

Can I use different mix-ins?

Absolutely! Feel free to customize with your favorite chocolate, nuts, or candies. Just keep the total amount of mix-ins similar to avoid affecting the dough’s consistency.

I hope these Brown Butter Oreo M&M Chip Cookies (Soft, Chewy, Bakery Style) bring as much joy to your kitchen as they do to mine. There’s something so comforting about a fresh-baked cookie, and these are truly special. Give them a try, and let me know how they turn out – I can’t wait to hear!
