Chocolate M&M Cookies – Soft, chocolatey cookies with a brownie-like center and pops of crunchy mini M&M’s in every bite. Easy to make, quick to bake, and perfect when you want a colorful, crowd-pleasing chocolate cookie without extra fuss.
These chocolate M&M cookies came out of one of those afternoons where I wanted something chocolatey, colorful, and a little nostalgic—but not fussy. The kind of cookie you bake when you’re already preheating the oven before you’ve fully decided what you’re making.
They’re rich without being heavy, soft in the middle, and dotted with mini M&M’s that melt just enough to look pretty but still give you that candy crunch.
If you’ve made my M&M Cookies or M&M Brownies, this one feels like it lives right between the two—cookie shape, brownie vibes

How To Make Chocolate M&M Cookis
- Mix the Dough – Cream the butter and sugars until smooth, then blend in the egg and vanilla. Stir in the dry ingredients, finishing with the milk and mini M&M’s to create a thick, chocolatey dough.
- Chill Briefly – Let the dough rest in the fridge so the cookies bake up thicker and hold their shape.
- Portion & Prep – Scoop the dough onto a baking sheet and press extra mini M&M’s on top for color and crunch.
- Bake Until Set – Bake just until the edges are firm and the centers still look soft.
- Cool & Store – Let the cookies cool slightly before moving them to a rack, then store once fully cooled.
Recipe Tips & Suggestions
- Use Soft Butter – Let the butter sit out until it presses easily with a finger so it creams smoothly with the sugars.
- Measure Cocoa Carefully – Too much cocoa can dry out the dough, so level it off rather than scooping straight from the container.
- Adding Milk – if you live in a dry climate or you add a tiny bit more flour, you will want to the 2 Tablespoons of milk. But if you life where it is humid, and you carefully spoon measure your flour, you will probably want 1 Tablespoon of milk. So if you dough is super dry use the full 2 Tablespoons, but you don’t want it to get sticky or wet.
- Don’t Skip the Chill – A short rest in the fridge keeps the cookies thicker and prevents them from spreading too much.
- Add M&M’s in Layers – Mix some into the dough and save a handful for the tops so every cookie looks loaded.
- Watch the Bake Time – Pull the cookies when the centers still look slightly soft; they’ll finish setting as they cool.
- Adjust Thickness Easily – Chill longer for thicker cookies or bake sooner for slightly flatter ones.
- Swap the Candy – Mini peanut butter candies or chopped chocolate-coated candies work well if that’s what you have.
Storage
Store cookies in an airtight container for 4-5 days before they will start to dry out.
You can freeze both the dough and the baked cookies. Scoop the dough first for easy baking later, or freeze cooled cookies in an airtight container for up to two months.
I am really craving a chocolatey cookie right about now! I might just have to go and make some!
Yay for chocolaty cookies! 🙂
These cookies are mouthwatering! I bet they did not last long around your house. My hubby adores m&m’s, so these would be perfect for him. Pinning!!
Wouldn’t it be great to go to the candy store and get M&M’s in your mom’s favorite color? These look delicious. So soft. I wish I had some this instant.
Whoa, Erin. These pictures are awesome! 🙂 The M&M cookies look amazing and love how you just pressed them on top. Will try that next time!
Saw these on Pinterest and yes. I need them.
Oh man, there’s nothing to not like about these! M&M cookies are my favorite, I cannot resist them 🙂 I have a ton of mini M&M’s in my pantry, these are happening soon!
Happy Mother’s Day! These cookies are way cute! Bet they are tasty, too!
Happy Mother’s Day! These look amazing — will definitely be making them soon!
Love your blog — I nominated it for a Liebster Award!
I just made these and they turned out horrible….they totally flatten out when I took them out. Not sure what happened. Pretty disappointed.
I am sorry the recipe didn’t work out for you. Did you chill the dough? I have a horrible time with thick cookies living at altitude, but this recipe has worked great for me, twice.
Erin….I did chill it….I thought maybe I made to big but made smaller ones and the same happened. Do u thi k it was maybe the baking soda?
Baking soda does go bad, so if yours was old that could have been an issue. I buy the smallest container of baking soda I can, because they say you should replace it every 6 months. Did you include the milk? I got the recipe from a friend and she has had great success with the recipe as well – so I really wonder what happened!
