Thin and Chewy M&M Cookies are soft, buttery, and M&M-covered! I’m sure you have had an M&M cookie before- maybe from the store, possibly from a bakery- but this cookie will easily rival any M&M cookie... or any cookie you have ever had. These are easy to make, call for ingredients you are sure to have in your kitchen, and are so delicious!
- Unsalted Butter: Unsalted butter is the fat and flavor in these cookies! You'll need room temperature butter, so leave your butter out for an hour before baking. It should be soft and cool to the touch!
- Sugars: You'll need both granulated and light brown sugar for this recipe! The combination creates the best texture and flavor!
- Egg: You'll need one, room temperature, egg for this recipe! This adds to the chewiness of these cookies!
- Vanilla Extract: Vanilla extract rounds out flavors in every recipe it's featured in!
- All Purpose Flour: Measure your all purpose flour correctly by spooning it into your measuring cups and leveling off the tops!
- Salt: Salt enhances the sweetness in these cookies!
- Baking Soda: Baking soda helps these cookies to puff just slightly! Though these cookies are on the thinner side, this ingredient is imperative for texture!
- Cornstarch: Corn starch is the secret ingredient for soft, stable cookies!
- Mini M&Ms: These are the stars of the show! I use the sharing size package! It's the perfect amount for coating these cookies! Here is a link if you're looking!
The ratio of butter to flour, the cornstarch, and the egg all contribute to the texture! However, this heavenly chewy texture mostly comes from butter. The butter seeps into every bite, creating an extra soft cookie!
If your cookies are spreading, this usually means that your dough was too warm or you do not have enough flour. This recipe does not require any chill time, but if you find that your first tray of cookies spread while baking, try freezing your remaining dough balls for 15 minutes. However, more than likely, you did not measure your flour (or other ingredients) correctly Make sure you are measuring precisely! With flour, specifically, you'll want to spoon the flour into your measuring cups before leveling off the tops with a knife!
I do not recommend using regular M&Ms in this recipe. These cookies are very thin, so the regular-size m&ms will not coat the cookies the same way.
Size and Bake Time
I make these Thin and Chewy M&M Cookies into 1-tablespoon-sized balls. I bake them for 9-10 minutes. Every oven is different!
Anywhere between 1 and 1.5 tablespoons is really a nice size for these cookies. If you want them smaller, just bake for less time. If you want them to be JUMBO, I would refrigerate the dough for 30 minutes before baking and form 2.5 tablespoon balls. Check on them at 15-16 minutes.
The cookie will look pretty small at the 6 minute mark, but do not worry. In just the last few minutes of baking, these guys will really grow!
These cookies will look slightly puffy when done. They will have a shimmer, meaning that they will look a little bit wet. If you want them to truly be soft with a barely crisp exterior, the tops will look light, not golden brown in the slightest. The edges should look like they have just begun turning in color.
You may notice that there are no M&Ms inside of the batter, only around the outside of the cookie. You will roll the dough balls in mini M&Ms. I HIGHLY recommend using mini M&Ms rather than regular size because the chocolate to cookie ratio will suffer.
Plus, you’ll add a few extra mini M&Ms after the cookies come out of the oven, and the heat from the cookies will soften the mini M&MS but won’t really do the same for regular-sized M&Ms. That means you’ll have crunchier cookies which will make these cookies seem less soft.
Storing and Freezing Chewy Cookies
These cookies will stay fresh at room temperature for up to 3 days. Store in an air-tight container.
You can freeze the dough, though I would freeze the dough in rolled balls. Freeze for up to 3 months. To bake, keep at room temperature until slightly sticky on the outside, about 30 minutes- 1 hour. At this point, you can roll the balls in mini M&Ms.
You can freeze baked cookies for about 2 months. I like to individually wrap them and bring them to room temperature before eating and serving.

Thin and Chewy M&M Cookies are soft, buttery, and M&M-covered! These are easy to make, require 30 minutes of your time, call for ingredients you are sure to have in your kitchen, and are so delicious! These will be your new favorite quick bake!
- ½ cup (110g) unsalted butter, room temperature
- ½ cup (120g) light brown sugar, packed
- ⅓ cup (75g) granulated sugar
- 1 large egg (50g), room temperature
- 1 tsp (4g) vanilla extract
- 1 ½ cups (225g) all purpose flour
- ½ tsp (4g) salt
- ½ tsp (3g) baking soda
- 1 Tablespoon (10g) cornstarch
- 1 sharing size (285g) mini M&Ms package
- Preheat your oven to 350 degrees Fahrenheit. Line two large baking sheets with parchment paper.
- In a large bowl, cream butter, light brown sugar, and granulated sugar until smooth and creamy. Beat on medium speed. This should take a couple minutes.
- Add room temperature egg and vanilla extract to the batter, mixing on medium speed and scraping down the sides and bottom of the bowl to ensure all of the ingredients are fully incorporated.
- Add flour, salt, baking soda, and cornstarch to the bowl. Begin mixing on low speed. Do not overmix. Mix until all of the dry ingredients are just incorporated. Dough will be light in color and very soft and sticky.
- Form dough into balls between 1 and 1 ½ tablespoons. Coat each dough ball in mini M&Ms. I chose to only coat the top and sides, leaving the bottom plain. Place dough balls at least 2 inches apart on the baking sheet.
- Bake at 350 for 9-11 minutes. Cookies will be light on top, puffy, and just starting to turn golden in color around the edges.
- After removing the cookies from the oven, stick extra mini M&M into the tops of the cookies.
- Allow cookies to cool on the baking sheet for about 10 minutes before transferring to a wire rack to continue cooling.

I made these yesterday and was so happy with how they turned out: sweet and chewy with a delightful chocolately crunch from the mini m&ms. Plus, the recipe was super easy to follow, making the baking process simple and quick. Most of my family went back for seconds, and I’m very excited to have another one later today. I will definitely make these cookies again soon!
Thank you so much for leaving such a kind review! I am so so happy to hear that you enjoyed both the process and result of these cookies!

Approved of by 4 out of 4 teenagers! Made a double batch last night for my kids, niece and nephew. Even had to substitute 1/2 of brown sugar with Keto brown sugar since I ran out of the regular and I only had 4 cookies left from the first batch! They were skeptical that these were the best cookies ever but I was right!
I am SO glad these cookies were enjoyed by you and your family! Thank you so much for taking the time to leave a review!
The BEST go-to cookie recipe!! My sister and I have made these cookies many time together, so much so that we have gotten quite confident making them! Confident enough to start trying different toppings! Cinnamon+ sugar mix, fruity pebbles, and pretzles+carmel+salt are some examples of what we have tried! Love these cookies!!!
This brought me the biggest smile! Thank you so much for this kind review, Kate!
