These big, chewy M&M cookies are a nostalgic treat that’s pretty much impossible to resist. Read on to find out how to make this classic cookie recipe!
Food bloggers usually start their blog posts by talking about the way a recipe tastes, but I think it’s a safe bet that you’re here because you know exactly what a perfect M&M cookie tastes like and you want to make them yourself. The best M&M cookies are chewy, buttery, full of milk chocolate flavor, and they have that irresistible bit of crunch from the candy shells. If that’s what you’re looking for, then this is the recipe for you!
Why You’ll Love This M&M Cookie Recipe
- Huge, glorious M&M cookies. Because there’s no such thing as too much M&M cookie, I made these cookies big by using a 3-tablespoon cookie scoop to portion out the dough. You can certainly make them smaller (be sure to adjust the baking time accordingly!), but when it comes to M&M cookies, I say you should go big or go home.
- Easy to make. If you can make traditional chewy chocolate chip cookies, you can make cookies with M&Ms. This recipe is a cinch!
- Always a hit. Colorful, chewy, buttery M&M cookies are a classic for a reason—everyone loves them! This recipe is guaranteed to put a smile on anyone’s face.
What You’ll Need

- All-purpose flour – Learn more: How to Measure Flour
- Baking soda
- Salt
- Unsalted butter – Learn more: Unsalted or Salted Butter: Which is Better for Baking?
- Light brown sugar – Dark brown sugar will impart more of a molasses flavor in the cookie dough, so I recommend sticking with light brown.
- Granulated sugar
- Egg
- Egg yolk
- Vanilla extract
- M&Ms – I used plain M&Ms, but you can use a flavored variety to switch things up, or different colors for different occasions and holidays. (See my Merry & Bright Christmas M&M Cookies!)
Can You Bake with Normal M&Ms?
Yes, you don’t need to buy the specialty bags of mini M&M baking bits that are sold alongside chocolate chips in the baking section. Just buy the regular-size, milk chocolate M&Ms for this recipe.
How to Make M&M Cookies
- Mix the dry ingredients. Whisk the flour, baking soda, and salt in a mixing bowl.
- Mix the wet ingredients. Use an electric mixer on medium speed to beat the butter and sugars in another bowl, until they’re smooth. Beat in the egg, egg yolk, and vanilla.
- Combine the wet and dry ingredients. Reduce the mixer speed to low and slowly add the flour mixture to the bowl with the eggs and butter, mixing just until combined. Fold in the M&Ms.
- Chill the dough. Refrigerate the cookie dough for 30 to 60 minutes. This keeps the cookies from spreading!
- Prepare. Preheat your oven to 325°F and line baking sheets with parchment paper or silicone liners.
- Form the cookies. Use a 3-tablespoon cookie scoop (or use a measuring spoon to portion the dough) to scoop the cookie dough, then use your hands to roll it into balls. Place the dough onto the prepared pans, leaving 2 to 3 inches between the cookies.
- Bake. Bake the cookies one pan at a time for 15 to 20 minutes, or until the edges are beginning to brown and the centers are still soft.
- Cool. Let the cookies cool on the pans on a wire rack for about 10 minutes, then remove them from the pans and place them directly on the racks to finish cooling. (Learn more: Why Every Baker Needs Wire Cooling Racks)
Why Are My M&M Cookies Flat?
If your M&M cookies are flat, it could be that you used too much sugar or butter, or too little flour. Skipping the chilling time for the dough will also result in cookies that spread. Finally, be sure you’re lining your baking sheets rather than greasing them—greased baking sheets encourage cookies to spread out.
Tips for Success
- Chilling the dough. Refrigerating the dough is an important step for achieving a chewy cookie that doesn’t spread during baking. You can refrigerate the dough for more than an hour, but if you do this, you’ll want to let it sit at room temperature for a bit afterwards so it’s easier to scoop.
- Adding chocolate chips. Some M&M cookies have a combination of M&Ms and chocolate chips. If you want to do this, simply swap out some of the M&Ms for milk chocolate or semisweet chocolate chips.
- Don’t overbake! Remember, the cookies will continue baking from the residual heat on the pan after you remove them from the oven, so it’s absolutely fine if the centers aren’t set. If you wait too long to remove them from the oven, the cookies will be crispy instead of chewy.
How to Store
- Room temperature: Stored at room temperature in an airtight container, M&M cookies will last about 3 to 4 days.
- Freezer: You can freeze M&M cookies in an airtight storage container or freezer bag for up to 3 months. If you’re stacking them, place parchment paper between the layers to keep them from sticking. Let them thaw at room temperature, or warm them up in the microwave for a few seconds.

Yum! These cookies look awesome…M&M cookies are so much fun!
I was that lucky recipient and they were yummy!!!! 😉
Congrats Jeanette!
They do look yummy!
yum! I love how the colours have stayed do vibrant and not bled into the cookie!
These look so pillowy and wonderful. I wish I was sinking my teeth into one right now!
It looks yummy and it’s nice colorful! 🙂
These look great and I’ve bought everything to make them but one question – do you leave the dough in balls or flatten them a bit before they go in the oven?
Julianne, you can flatten them slightly if you’d like. They will spread a good bit either way.
I just made these cookies with red & green M & M’s for Christmas! They turned out really good! So happy!
Really good recipe! Thank You!
Did anyone else find the dough super sticky? It was so sticky for me to roll so I just scooped some in my Hand and dropped it on the tray. The dough did taste yummy though 🙂
Absolute favorite kind of cookie! Can’t wait for the chewiness of these, knowing me ill use just a bit more chocolate chips than recommended. Gotta satisfy that sweet tooth (and these will!)
What should I do with the cookie dough that is waiting for the oven? Leave it out or put it in the refrigerator?
I usually chill cookie dough between batches.
Can I substitute any kind of candy for the m&m’s, such as snickers, milky way or peanut m&m’s??
Made these cookies yesterday. They only lasted for 2 days. Making a new batch as we speak. Best m@m cookies i’ve ever made!
How wonderful to hear! I’m glad they’re a hit, Lisa.
I know it’s been years since you posted this recipe, but I just baked these delicious cookies today. I used a 3TB scoop and baked them 6 to a sheet for 17 minutes. They came out perfect and I didn’t change a thing in your recipe.
My only other comment would that the yield amount is wrong, at least if you use the 3TB scoop. I ended up with 18 delicious cookies.
Thanks for your feedback about the yield. It’s been a while since I’ve made these, so my memory of their specifics is vague at this point. In any case, I’m glad you liked them, Judith!
