Chewy Oatmeal M&M Cookies.

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.

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

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

Yield: 20 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)


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.

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.

Preheat oven to 325F degrees. Line two large baking sheets with parchment paper or silicone baking mats.

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.

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

Additional 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.

    Oh My Goodness!! These are so amazing looking. I have been trying for years to find a recipe that gives a nice chewy texture. All the others I’ve found are either hard or cake like. Two things that never come to mind when I think of a cookie fresh from the oven. Thanks for sharing all your delicious recipes!!

    Wynnposted September 24, 2013 at 1:16 am

    This recipe is awesome! I changed a little here and there and yet it still turned out very yummy. My family loves it. Especially the kids. I already baked two times in this week alone. I reduced total sugar to just 1/4 cup brown sugar and plain flour to wholemeal flour. I added two tbsp low fat milk because the whole wheat flour seems a little dry. The sweetness is just nice for us! All because of the m&m and raisins!

      Yes, you can chill it overnight. Be sure to cover the dough tightly and chill. Let it sit at room temperature for 10 minutes because it will be rock hard.

    • Sallyreplied on February 21st, 2014 at 7:01 pm

      Try adding 1/3 cup oats (so use 1 and 1/3 cups total) – that will help!

      I’m so glad I’m not the only one. Did you chill yours both times? I’m going to try not chilling mine. Hmmm… I just had a thought….I don’t know what kind of oats I used…what kind/brand did you use? I wonder if that could make a difference?

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.
