Chocolate Chip M&M Cookies
These bakery-style massive Chocolate Chip M&M ® Cookies make for such a great treat. They’re soft, chewy, and loaded with chocolate! Plus they’re massive and who doesn’t like huge cookies?!
So what are the two secret ingredients? Whipped egg whites and oat flour! Curious? Read on.
How to make these cookies
- Combine the butter, brown sugar, and white sugar.
- Cream the ingredients together, either in a stand mixer or with a hand mixer. Take your time here, because we want the dough to be very creamy and smooth.
- Add in two large egg yolks and the vanilla extract and mix to combine. (Use the extra egg white in this easy egg wrap recipe.)
- Combine the one egg white with cream of tartar. (Here’s a description of what cream of tartar does in baked goods)
- Beat until light and fluffy.
- Add the egg mixture to the wet ingredients and fold to combine.
- Combine all the dry ingredients and stir to combine.
- Add dry ingredients to wet ingredients.
- Mix until you’ve got a thick smooth dough. Avoid overmixing the dough; stir until everything is just combined.
- Add in the regular-sized and miniature chocolate chips.
Instructions, continued
- Stir to evenly disperse the chocolate.
- Measure balls of dough using a ¼-cup measuring cup to measure the balls of dough.
- Roll into flat wide discs and press M&M’s on top.
- Bake! Add a few more chocolate chips and/or M&M’s on top to make these cookies pretty and ensure there is chocolate in every bite of these scrumptious cookies!
Chocolate Chip M&M Cookies Baking Tips
- Accurately measure flour: Pushing a measuring cup into a bag or container of flour will pack in way more flour than is needed. To properly measure your flour, spoon the flour into the measuring cup until it’s overfilled. Then use the back of a knife to level the measuring cup at the top. (Video visual here)
- Room-temperature eggs and butter: Don’t melt the butter or the cookie dough will need to be chilled before baking. Check out this guide to bringing eggs and butter quickly to room temperature.
- Use quality ingredients: Choose real butter (not margarine), pure vanilla extract, and high-quality chocolate chips (I recommend Guittard® or Ghirardelli®) for the best flavor.
- Use a ¼-cup measuring cup to get consistent dough ball sizes. This will ensure even baking.

Chocolate Chip M&M Cookies
These family-favorite Chocolate Chip M&M Cookies are crisp on the outside, soft on the inside, and they feature two secret ingredients!
Equipment
- Sheet pan lined
Ingredients
- 3/4 cup unsalted butter room temperature
- 3/4 cup light brown sugar lightly packed
- 6 tablespoons granulated sugar
- 1 large egg
- 1 egg yolk
- 1/2 teaspoon cream of tartar
- 2 teaspoons vanilla extract
- 1/4 teaspoon salt
- 1 teaspoon baking soda
- 2-1/4 cups flour see note 1
- 2 tablespoons blended oats see note 2
- 1-1/2 cups chocolate chips
- 1/2 cup mini chocolate chips or chocolate chunks
- 1/2 cup M&M's
Instructions
- Preheat the oven to 350℉. Line a large sheet pan with parchment paper or a silicone baking mat and set aside.
- In a large bowl, beat together the butter, brown sugar, and granulated sugar until light and creamy, about 3-4 minutes.
- Separate the egg yolks from egg whites, discarding one of the egg whites. Beat the egg yolks and vanilla extract into the sugar and butter mixture. Place the remaining egg white in another bowl. Add the cream of tartar to the single egg white and beat for several minutes until light and fluffy. Add egg white mixture to the rest of the wet ingredients and mix until combined.
- In another bowl, mix together the salt, baking soda, flour, and blended oats (see note 2 for blending instructions). Stir until combined.
- Combine the dry and wet ingredients and stir until just combined. Stir in regular chocolate chips, and miniature chocolate chips or chocolate chunks. Don't add M&M's at this point
- Use a 1/4-cup measuring cup to measure out the dough onto a cookie sheet. Strategically place extra chocolate chips and the M&M's on the tops of the cookies. Roll into big dough balls even in width and height. Place no more than 4 cookies on the sheet pan.
- Bake in a fully preheated oven for 10-12 minutes or until the sides are lightly browned. Remove from the oven and allow the heat from the pan to finish baking the cookies on the sheet for about 4-5 minutes before transferring to a cooling rack. Underbaking your cookies is key to soft and chewy cookies. These cookies have a very soft and chewy center with crisp edges.
Recipe Notes
Note 1: Pushing a measuring cup into a container of flour will pack in way more flour than you need. To properly measure your flour, spoon the flour into the measuring cup until it's overfilled. Then use the back of a table knife to level the measuring cup at the top (video visual here).
Note 2: If you have quick oats or old-fashioned oats, you can easily make oat flour in minutes. Simply add the oats to a food processor or small blender jar and pulse until they reach a powdery consistency. Stir to ensure all oats are finely ground and no whole oats remain, as this will impact the texture and liquid absorption of the cookies. Be sure to measure the flour after blending, not before.
Storage: Store cooled cookies in an airtight container at room temperature for up to 5 days.
To freeze, scoop the cookie dough into balls and place them on a lined baking sheet. Freeze the dough balls until firm, then transfer them to a sealed bag or container. Store in the freezer for up to 3 months.

Wow just made these wish I could show a photo of them. Very good recjpe !!
Ahh I wish I could see a picture of them. I’m so glad you enjoyed! Thanks Sheila! 🙂
OMG! this is THE recipe, these are the best cookies by far I have ever tasted!
CONGRATS!
Ahh this is the best compliment! Thank you so much! <3
Can you make these into peanut butter cookies by just omitting the chocolate chips? I am going to make these tonight and we are going to have them on Mother’s Day!!
The base won’t be peanut butter flavored; I’d recommend these peanut butter cookies: https://www.chelseasmessyapron.com/peanut-butter-cookies/ and you can add M&Ms to those too! Thank you very much!
Can i refrigerate the dough over night and bake it the next day?
Sure!
Love these cookies! Quick question (although I realize this is an olderish post!)….does it matter if it’s dark brown sugar or light brown sugar? I’ve made them before and they were perfect, however, I made them this weekend and they are crunchy. I can’t remember which I used and am wondering if you have a preference. Thanks!
I use light brown sugar 🙂 If they were crunchy they could have been a bit overbaked or perhaps the flour was over-measured a bit. Hope that helps!
Hi! These look great! Can’t Wait to try them out! How do you achieve the pre-oven look? It seems almost swirly, not like a flattened ball… thanks!
Amazing cookies… Looks divine too definitely will try. One doubt if I want to reduce the egg to one so I hve to reduce the quantity in each ingredient rite. So,, 3/4″half I hve to put”how can half.
If you half part of the recipe you’ll want to halve it all. So half of 3/4 cup is 1/4 cup + 2 tablespoons (6 tablespoons). Enjoy these!
What if I want to leave out the 1/2 cup of chocolate chunks and the M & M’s . Do I use 2 1/2 cups of chocolate chips to make up for the amount or just use 1 1/2 cups of chocolate chips ?
Otherwise does the amount of extra stuff affect the consistency or thickness of the dough??
I’ve been looking for the perfect bakery style cookie and finally came across your fabulous recipe. They came out perfectly. Thank you so, so much!
You are so welcome!! I’m glad you enjoyed these Katie 🙂
These look fantastic – but wonder can I make them smaller than 1/4 cup? If so, how long would you bake for? Thank you so much for sharing!
