My favorite super chewy and soft oatmeal cookies loaded with M&M candies!

Oatmeal cookies, of any kind, will always be my favorite. The chewy, buttery oats and sweet brown sugar all packed into one perfectly soft cookie makes me weak at the knees. I made this new recipe last weekend when I had a request to bake some cookies with M&Ms. I recently made my Rainbow M&M Cookies, so I wanted to whip up something a tad different. Oats to the rescue!

This oatmeal cookie recipe is easily one of my favorites because the cookies carry an ideal oatmeal cookie texture. A perfect textural balance, if you will. Soft and buttery in the center, chewy and somewhat crisp on the edges… something I find hard to master.

Cinnamon, brown sugar, and old-fashion rolled oats give the cookies a certain warmth and familiarity I associate with home. Your comforting cookie, indeed. And speaking of comforting, I’d like to add that the oats just cancel out the butter here, so let’s just consider these cookies a health food.

Chewy Oatmeal M&M Cookies

My favorite super chewy and soft oatmeal cookies loaded with M&M candies!


  • 1/2 cup (115g) unsalted butter, softened to room temperature
  • 3/4 cup (150g)dark brown sugar, packed
  • 1/4 cup  (50g) granulated sugar
  • 1 large egg
  • 2 teaspoon vanilla extract
  • 1 and 2/3 cups (140g) old-fashioned rolled oats
  • 1 cup (125g) all-purpose flour
  • 1/2 teaspoon ground cinnamon
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 cup (160g) mini M&Ms (or regular size)


  1. Using a hand mixer or a stand mixer fitted with paddle attachment, cream the softened butter and both sugars together on medium speed until smooth. Add the egg and vanilla and mix on high until combined, about 2 minutes. Scrape down the sides and bottom of the bowl as needed. Set aside.
  2. In a separate bowl, toss the oats, flour, cinnamon, baking soda, and salt together. Add to the wet ingredients and mix on low until combined. Fold in the M&Ms. Dough will be thick. Chill the dough for at least 30 minutes in the refrigerator.
  3. Preheat oven to 325F degrees. Line two large baking sheets with parchment paper or silicone baking mats.
  4. Roll balls of dough (about 1 tablespoon of dough per cookie) and place 2 inches apart on the baking sheets. I pressed a few extra M&Ms into the tops of the cookies for looks. Bake for 10-11 minutes until very lightly browned on the sides. The centers will look very soft. Remove from the oven and let cool on baking sheet for 5 minutes before transferring to a wire rack.

Sally's Tip: Cover cookies and store at room temperature for up to 1 week. Baked cookies and rolled cookie dough freeze well, up to 3 months.

Recipe Notes:

Sally's tip:  The cookies will be very soft and may appear undone after only 11 minutes in the oven, but they will firm up as they cool.

  1. Sally saves the day! I was planning on bringing cookies to a friend’s house and I had started out making cookies from a new recipe (another site) and they weren’t holding – complete fail. 🙁 I quickly went to your site and looked for a recipe that would work with the ingredients I had on hand and found this. These were so easy and delicious. The recipients loved them as well and declared that these must be better than whatever I was going to make originally. I agree! Thanks so much, Sally!!!

  2. Hi Sally! This was my first time baking oatmeal cookies and they were absolutely delicious! I love that they don’t require much chilling time so I think this recipe will be on high rotation at my house!
    I’ve pre-ordered your recipe book, and it’s coming all the way to Australia 🙂 can’t wait to try out your other recipes!!

  3. These look amazing and I’m about to make them today! One question…what can I do to make them if I don’t have a baking silpat or parchment paper?

  4. Thank you for using grams! I’ve been converting ingredients for years and have been doing it wrong. I stopped baking. Now, your recipies are working out and are the best ever! Every one I try is perfect!

  5. YUMM!
    I just finished baking these and they are DELICIOUS! I made them slightly bigger and rolled using your tower method and baked for an extra minute and they turned out perfect. Your recipes never disappoint!
    Thanks again for another delicious cookie recipe!!!

  6. Sally! I made these this weekend and WOW. I’ve been making cookies since I was about 8 years old and these could be the new go-to recipe! We had my sister’s bachelorette and had a party bus around Boston & they hit the spot. I also made sure our bus driver tried the best cookies I’ve ever made! Have an amazing time in Hawaii! Xo

  7. These were good. I used quick oats and they turned out great.

  8. Let me say, I have never commented on a blog post before, but these cookies…
    I’ve been looking for a great oatmeal cookie for years. Finally found it! These are perfect! Thank you for the recipe!

  9. Oh these M&M cookies look great! I am doing a post about M&M’s and your recipe is going to be one of the features. My readers will LOVE it!

  10. I’ve already made three batches of these cookies in a week!! Everyone loves them, they go so fast. In fact, my mom said these were the best cookies I’ve ever made. I did alter them a bit though. We’re not fans of m and m’s so instead I added craisins, raisins, toffee bits and unsweetened shredded coconut OMG lol!! So good. .. I also added some sprinkles, because why not? The second and third batches I made I just put in craisins, raisins, coconut and white chocolate chips!! Absolutely delicious. I keep thinking about what else I could put in them… Maybe peanut butter 🙂

    Thank you for this amazing recipie… This is now my go to oatmeal cookie!!

  11. I have the dough chilling in my fridge right now! I saw the recipe and knew I couldn’t wait. I’ll how they are when I’m don’t but pretty sure they are being added to my Christmas baking list this yr 😉

    One question: I thought peanut butter would be good in them to, would you add peanut butter or peanut butter chips?

  12. I totally suck at making cookies. Over n over I’ve tried for only burnt or half raw or dry cookies.
    Thanks to your cookie recipe… I have made two whole batches of PERFECT cookies!!

    Awesomeness. .. thank you!!

  13. Why dark brown sugar?
    whats the difference?

  14. These cookies are great! I just baked them on the regular oven setting but was wondering if, in general, you use the convection or regular setting on the oven. Thanks – your recipes are so great!

  15. I’ve made these before and they were delicious! I am making them today for a Christmas party but the I want to bake them on convection because I feel it makes a better cookie (soft center with crispy edge)!! Do you have a recommendation for baking temp and time? Thanks, Nicole

  16. I just made these for a holiday party and they are the best cookies I’ve ever made! Thank you!!!

  17. Excellent recipe. Love these cookies with the mini M&Ms. Thanks Sally!

  18. I just made these tonight on a whim because I had some leftover M&Ms from the holidays kicking around that needing something done with them (so I didn’t chow down on them all in one sitting!) and they.are.incredible. My brother practically melted when he popped one in his mouth. Definite keeper right here, wow!

  19. I made these for the SuperBowl in Patriots and Seahawks colors- seriously one of the best cookie recipes I have ever made. They are flying!!! I can’t wait to use the oatmeal cookie base with different types of m&m and other additions. Thanks for this new staple!!!!

  20. I made this recipe tonight. Very tasty and east to do! Thanks for the recipe!

  21. would you happen to have the nutritional value for this recipes? They look wonderful and would really like to make them!

  22. could i use maple syrup or honey in place of the sugars ? and possible a butter substitute ? like half nut butter or bananas ? would it work ?

  23. These came out amazing! Some of them I over cooked a little so they were not as chewy but the rest were still chewy 2 days later. This is my new favorite recipe!

  24. These were the best cookies I ever made! I’m so happy I had some leftover dough so I can make more! Thank you!! 🙂 

  25.                  Hi Sally. Thank you for such beautiful pictures of the food u make. The old saying that you first eat with your eyes is so very true and that rings true for me when I stroll thru your recipes. Your pictures always make me wanna go in my kitchen and use my we’ll fairly new kitchen aid mixer that I recived for Christmas last year.  I do have a question about the recipe. Can u use light brown sugar, also can quick cooking oats be used and lastly can this recipe be doubled and if so is there any changes that need too be made? Thanks so much love your site I’m addicted lol.

    • Hi Renee- thank you! You can use light brown sugar, I do not recommend quick oats as some texture will be lost but you can certainly use them if that’s all you have on hand, and you can double the recipe without any special changes.

  26.            Just wanted too say hi and thank you for all the wonderful recipes. I always end up coming back to your web site. Thanks again.

  27. I LOVE you for using grams. No need to use converters! <3

  28. I made these cookies because I had some Christmas M&Ms and I didn’t have the right ingredients to make another recipe of yours. Boy am I glad I didn’t because they cookies are amazing. They melt in your mouth and the texture of the oats is wonderful. Never underestimate the power of a simple cookie!!!!

  29. Yum! Is there a way to make these cookies? Do I need to do anything different? Merry Christmas to you and your family! 

  30. Made these wonderful cookies tonight! So yummy and soft…perfect way to get in my oatmeal cookie fix 🙂 Thanks Sally!! 

  31. Perfect cookies!

  32. Omigosh are these good! I can’t wait to make Oatmeal Scotchies with this recipe. I’ve never used dark brown sugar with a cookie recipe but I really like the flavor it adds and how it stands up to the oatmeal.

  33. We’ve made these a thousand times and love them, but this time we used whole wheat flour and they didn’t turn out the same…it’s like it’s taking longer to bake? Any ideas? Thanks
