Chocolate Chip Oatmeal M&M’s Cookies

I don’t know why I’ve never shared a recipe for oatmeal cookies with M&M’s until now. Better late than never. I have so many recipes for M&M cookies and my love for oatmeal cookies is undying. Cookies with oats are my thing because I love the chewiness.

To make these easy cookies I spiked The Best Oatmeal Chocolate Chip Cookies with M&M’s and was in chewy yet soft cookie heaven. Make sure not to overbake them and they’ll stay soft and chewy for days.

These oatmeal chocolate chip M&M’s cookies are hearty but not overly dense and just thick enough but not too thick. Sometimes when oatmeal cookies are overly thick they can turn dry or cakey, a total deal-breaker. But not these.

Between the chewy oats, the gooey melted chocolate, and the slight crunch from the M&M’s, there’s wonderful texture in every bite.

A funny story about these homemade M&M’s cookies is that I baked them on a day I had a charity donation pickup truck coming to my house to pickup old clothes, furniture, and odds and ends I didn’t need in advance of a move. I gave half the batch to the guys picking up the donations and after trying one, one of the guys asked, “Will you marry me?”

You know a cookie is beyond good if you get a marriage proposal from it.

What’s in Oatmeal M&M’s Cookies? 

To make these oatmeal M&M’s cookies, you’ll need: 

  • Egg
  • Unsalted butter
  • Light brown sugar
  • Granulated sugar
  • Vanilla extract 
  • Old-fashioned oats
  • All-purpose flour
  • Baking soda
  • Salt
  • M&M’s
  • Semi-sweet chocolate chips

How to Make Oatmeal M&M’s Cookies

Simply cream together the egg, butter, sugars, and vanilla, then mix in the dry ingredients. Gently fold in the M&M’s and chocolate chips before scooping the dough into 1/4 cup balls. 

Chill the dough for at least 3 hours. Once chilled, bake the oatmeal, chocolate chip, and M&M’s cookies until the edges have set and the tops are just set, even if slightly undercooked, pale, and glossy in the center. 

Can I Use Instant Oats? 

No, you need to use old-fashioned whole-rolled oats. Quick cook or instant oats will behave more like flour, rendering the dough too dense, and aren’t recommended in this recipe.

Can I Omit the Oatmeal? 

If you’d rather make classic chocolate chip M&M’s cookies, I recommend making my Soft and Chewy M&M’S Cookies instead. I’ve made that recipe multiple times and it turns out perfectly every time.

Tips for Making Oatmeal M&M’s Cookies

Note that you MUST chill the cookie dough. Baking with unchilled dough will result in cookies that are thinner, flatter, and more prone to spreading.

These oatmeal chocolate chip M&M’s cookies will keep airtight at room temperature for up to 1 week or in the freezer for up to 6 months.

Alternatively, unbaked cookie dough can be stored in an airtight container in the refrigerator for up to 5 days, or in the freezer for up to 4 months, so consider baking only as many cookies as desired and save the remaining dough to be baked in the future when desired.

Ingredients  

  • 1 large egg
  • ½ cup unsalted butter, 1 stick
  • ½ cup light brown sugar, packed
  • ¼ cup granulated sugar
  • 1 tablespoon vanilla extract
  • 1 ½ cups old-fashioned whole rolled oats, not instant or quick cook
  • ¾ cup all-purpose flour
  • ½ teaspoon baking soda
  • ½ teaspoon salt, or to taste
  • 1 cup M&Ms, I used plain, plus more for the tops
  • ½ cup semi-sweet chocolate chips

Instructions 

  • To the bowl of a stand mixer fitted with the paddle attachment (or large mixing bowl and electric mixer) add the egg, butter, sugars, vanilla, and beat on medium-high speed until creamed and well combined, about 4 minutes.
  • Stop, scrape down the sides of the bowl, and add the oats, flour, baking soda, salt, and beat on low speed until just combined, about 1 minute.
  • Stop, scrape down the sides of the bowl, and add 1 cup M&Ms, chocolate chips, and beat on low speed until just combined, about 15 to 30 seconds.
  • Using a large cookie scoop, 1/4-cup measure, or your hands, form approximately 12 equal-sized mounds of dough, roll into balls, and flatten slightly. Tip – Strategically place a few extra M&Ms on top of each mound of dough for visual appeal.
  • Place mounds on a large plate or tray, cover with plasticwrap, and refrigerate for at least 3 hours, up to 5 days. Do not bake with unchilled dough because cookies will bake thinner, flatter, and be more prone to spreading.
  • Preheat oven to 350F, line a baking sheet with a Silpat or spray with cooking spray. Place dough mounds on baking sheet, spaced at least 2 inches apart (I bake 8 cookies per sheet) and bake for about 11 to 12 minutes, or until edges have set and tops are just set, even if slightly undercooked, pale, and glossy in the center; don’t overbake. Cookies firm up as they cool.
  • Allow cookies to cool on baking sheet for about 10 minutes before serving. I let them cool on the baking sheet and don’t use a rack.

Notes

  • Cookies will keep airtight at room temperature for up to 1 week or in the freezer for up to 6 months.
  • Alternatively, unbaked cookie dough can be stored in an airtight container in the refrigerator for up to 5 days, or in the freezer for up to 4 months, so consider baking only as many cookies as desired and save the remaining dough to be baked in the future when desired.

    I made these and everyone loved them! Quick question though, for next time: How would these turn out if they were smaller – like half the size, using 2 TBS dough instead of 1/4 cup? T

  3. Another hit – and turned out great with gluten free flour! I made a double batch and split it in half and did one batch with the chocolate chips and M&Ms (as per this recipe) and another with half chocolate chips and raisins – I think I actually liked the raisins in it better, but both were delicious. Maybe next time I will try all 3 mix ins! Very easy to make and turned out well, I also made some smaller and both sizes are great. Holding up 3 days later, although I don’t think they will be around much longer! Now I need to decide what cookie is up next to bake – I’m leaning towards soft and chewy peanut butter oatmeal chocolate chip, but you have so many combos that sound amazing!

    1. Thanks for trying the recipe and I’m glad it came out great with all the various add-ins! Sounds like you’re on a roll – enjoy the next cookies and LMK what you choose!

  6. These look so fantastic. The best is right! I am a huge fan of adding M&Ms to most things but cookies are by far my favorite. Yum!

  7. I know how good your cookie recipes are so I can see marriage proposals over them!! You’ve perfected the thick yet soft and chewy cookie with so many fun combinations. Oats with 2 kinds of chocolate is a total winner. Have a nice holiday weekend!

  8. I’d ask you to marry me too, Averie. That was so nice of you! I’m sure they appreciated the cookies, and I’m even more sure these are the best. Any soft and chewy oatmeal cookie is worth eating 20 of!
