The smell of toasted coconut sugar and melted butter hits you the second you open the oven door. It's a warm, comforting scent that feels like a hug. I remember the first time I tried to make these for a friend's birthday - I didn't use cornstarch and they came out like thin wafers.
They were okay, but they didn't have that thick, plush center that makes a cookie feel like a treat.
After a few rustic attempts in my own kitchen, I realized the secret isn't in the brand of candy, but in the hydration of the dough. When you get the balance of brown sugar and coconut sugar just right, the cookies stay soft for days.
This is how you get the best soft chewy mm cookies that actually hold their shape and don't just puddle on the pan.
Expect a cookie that's dense and satisfying, with pops of chocolate and the classic crunch of M&Ms. We're going for a look that's slightly imperfect and homemade, not something from a plastic factory. Trust me, the little cracks on top are where the flavor lives.
Best Soft Chewy MM Cookies
Other recipes often rely on too much white sugar, which makes cookies spread and crisp up too much. By using a blend of coconut sugar and light brown sugar, we keep the moisture locked in.
The molasses in the brown sugar creates that signature "bend" and a deeper, caramel like flavor that pairs well with the milk chocolate of the candies.
It's also about the fat. Softened butter, rather than melted butter, allows us to whip air into the dough during the creaming process. This prevents the cookies from becoming heavy bricks while still keeping them from thinning out too much. If you're used to the pizza dough recipe style of kneading and structure, this is the opposite - we want minimal gluten development here.
The addition of a tiny bit of cornstarch is the real pro move. According to King Arthur Baking, cornstarch helps soften the proteins in the flour, resulting in a more tender crumb. This is what transforms a standard cookie into something truly velvety.
- Moisture Retention
- Brown sugar is hygroscopic, meaning it attracts water, keeping the center soft.
- Protein Softening
- Cornstarch interferes with gluten formation, preventing a bread like texture.
- Leavening Balance
- Baking soda reacts with the acidic sugars to create a gentle lift.
- Fat Distribution
- Creaming butter traps air bubbles that expand in the heat.

The Ingredient List
Grab these items. I've listed the imperial weights since that's what works best for me, but keep it simple.
- 113g unsalted butter, softened Why this? Provides the base flavor and richness (Substitute: Vegan butter sticks)
- 100g coconut sugar Why this? Adds a rustic, toasted sweetness (Substitute: Light brown sugar)
- 100g packed light brown sugar Why this? Key for the chewy texture (Substitute: Dark brown sugar for more molasses)
- 1 large egg, room temperature Why this? Binds everything together (Substitute: Flax egg, though it'll be denser)
- 5ml pure vanilla extract Why this? Rounds out the sugar notes (Substitute: Maple syrup)
- 250g all purpose flour Why this? The main structure (Substitute: 1:1 gluten-free blend)
- 5g cornstarch Why this? The secret to the "soft" part (Substitute: Arrowroot powder)
- 5g baking soda Why this? Helps them rise and brown (Substitute: 1.5 tsp baking powder)
- 3g sea salt Why this? Cuts through the sweetness (Substitute: Table salt, use slightly less)
- 250g M&M candies Why this? The star of the show (Substitute: Rainbow chocolate gems)
- 30g semi sweet chocolate chips Why this? Adds a darker chocolate hit (Substitute: Chopped dark chocolate)
Chef's Note: If your butter is too soft (basically melted), your cookies will spread. It should be cool to the touch but indent when you press it.
Essential Baking Tools
You don't need a fancy kitchen to make the best soft chewy mm cookies. A basic setup will do. I use a standard stand mixer such as a KitchenAid, but a hand mixer or even a sturdy whisk and some elbow grease works fine.
You'll need a couple of large baking sheets and parchment paper. Don't skip the parchment - it prevents the bottoms from burning and makes cleanup a breeze. I also recommend a cookie scoop.
It's not about being precise, it's about making sure every cookie is the same size so they all finish baking at the exact same time.
Finally,, a wire cooling rack is essential. If you leave them on the pan too long, the bottoms keep cooking, and you lose that soft center we're working so hard to get.
step-by-step Method
Let's get into it. Follow these steps and you'll have a tray of colorful, comforting treats in no time.
- Cream the softened butter with the coconut sugar and brown sugar on medium high speed for 2-3 minutes until the mixture is pale and fluffy. Note: This incorporates air for a better lift.
- Incorporate the egg and vanilla, mixing until fully emulsified and smooth.
- In a separate bowl, whisk together the flour, cornstarch, baking soda, and salt.
- Gradually add the dry ingredients to the wet base on low speed, mixing until just a few streaks of flour remain. Note: Overmixing makes them tough!
- Fold in the M&M candies and chocolate chips by hand using a spatula until evenly distributed.
- Scoop rounded tablespoons of dough onto parchment lined sheets, spacing them 2 inches apart.
- Bake at 350°F (175°C) for 10-12 minutes until edges are set and golden but centers look slightly soft.
- Let the cookies rest on the hot pan for 5 minutes to firm up via residual heat.
Chef's Note: If you want that "bakery look," press a few extra M&Ms into the tops of the cookies immediately after they come out of the oven.
Fixing Common Cookie Issues
Baking is a bit like a science experiment. Sometimes things go sideways. If your cookies didn't turn out exactly how you wanted, don't toss them - just adjust for the next batch.
Cookies Spread Too Much
This usually happens when the butter was too warm or the dough didn't have enough structure. If the butter is oily, it melts faster than the flour can set.
Dry Crumbly Texture
Overbaking is the biggest culprit here. Even one extra minute in the oven can turn a chewy cookie into a biscuit.
Burnt Bottom Edges
This can happen if your baking sheets are too thin or your oven runs hot. Using a double sheet (stacking two) can create a buffer.
| Problem | Root Cause | Solution |
|---|---|---|
| Flat cookies | Butter too soft | Chill dough 30 mins before baking |
| Cakey texture | Too much flour | Use a scale for exact measurements |
| M&Ms cracked | Oven too hot | Check temp with an oven thermometer |
Common Mistakes Checklist - ✓ Did you cream the butter and sugar long enough? (It should look fluffy!) - ✓ Did you avoid overmixing the flour? (Stop as soon as streaks disappear) - ✓ Did you pull them out while the center still looked slightly underbaked?
- ✓ Is your egg at room temperature? (Cold eggs can break the emulsion) - ✓ Did you leave them to rest on the pan for 5 mins?
Fun Flavor Variations
Once you've mastered the original, you can start playing around. I love adding a handful of crushed pretzels to these for a salty kick. It creates a great contrast with the sweet chocolate.
If you're not in the mood to turn on the oven, you can always make my edible cookie dough recipe and just stir in the M&Ms. It's a great way to satisfy the craving without the wait.
For a holiday version, use red and green M&Ms and add a pinch of cinnamon to the dry ingredients. For a nutty twist, fold in 50g of toasted pecans. Just remember, if you add a lot of extra "stuff," you might need to add a tablespoon more flour to keep the dough from becoming too wet.
Adjusting Your Batch Size
Scaling cookies isn't always a linear process. If you're making a smaller or larger batch, keep these tips in mind.
Scaling Down (1/2 Batch) Use a smaller baking sheet to maintain heat distribution. Since you can't easily split an egg, beat one egg in a small bowl and use half of it (about 25g). Reduce the bake time by about 20%, as smaller batches sometimes heat up faster.
Scaling Up (2x Batch) Don't just double the salt and baking soda - increase them to 1.5x first and taste. Too much leavening can leave a metallic aftertaste. Work in batches rather than overcrowding one giant bowl, as this ensures the M&Ms are evenly distributed.
If you're baking more trays at once, lower the oven temperature to 325°F (160°C) and extend the time by 2-3 minutes to ensure even browning.
| Batch Size | Butter | Flour | Baking Adjustment |
|---|---|---|---|
| Half (12 cookies) | 56g | 125g | Check doneness at 9 mins |
| Double (48 cookies) | 226g | 500g | Lower temp to 325°F |
Cookie Baking Myths
Myth: You must chill the dough for 24 hours. While chilling deepens the flavor, it's not mandatory for this recipe. Because we use cornstarch and a specific sugar blend, you can bake these immediately and they'll still be chewy. Chilling just makes them thicker.
Myth: Using salted butter ruins the recipe. Not at all. If you only have salted butter, just reduce the added sea salt to a pinch. The salt is actually what makes the chocolate taste more intense.
Myth: M&Ms will melt and bleed colors. If your oven is at the correct temperature (350°F), the candy shells should stay mostly intact. If they bleed, your oven is likely running too hot, which also causes the cookies to spread.
Storing and Reheating Tips
To keep these cookies velvety, store them in an airtight container. I swear by the "bread trick" - put a single slice of white bread in the container with the cookies. The cookies will absorb the moisture from the bread, staying soft for up to 5 days.
In the fridge, they'll last about a week, but they get quite hard. I actually love a cold M&M cookie, but for the best experience, give them a quick zap.
For freezing, flash freeze the scooped dough balls on a tray for an hour, then toss them into a freezer bag. You can bake them straight from the freezer - just add 2 minutes to the bake time.
Reheating for that Fresh Baked Experience Pop a cookie in the microwave for 8-10 seconds. This softens the butter and melts the chocolate chips just enough to make them gooey again. It's the closest you'll get to the moment they first came out of the oven.
The Best Pairings
These are quite sweet, so you want something to balance that out. A cold glass of whole milk is the classic choice, but a tart raspberry coulis or some fresh sliced Granny Smith apples provide a great acidic contrast.
If you're putting together a dessert spread for a party, these go great with some savory snacks to cleanse the palate. I often serve them alongside Homemade Bread Bowls filled with a creamy dip. The saltiness of the bread makes the sweetness of the best soft chewy mm cookies stand out even more.
For a drink, try a strong dark roast coffee or a cold brew. The bitterness of the coffee cuts right through the sugar and highlights the vanilla and coconut notes in the dough. Trust me, that combination is a total winner.
Recipe FAQs
Why is cornstarch added to the flour?
It softens the protein in the flour. This prevents too much gluten development, ensuring the cookies stay tender and chewy rather than cakey.
How to tell when the cookies are perfectly baked?
Remove them when edges are golden but centers look slightly soft. They will finish firming up on the hot pan for 5 minutes via residual heat.
Is it true I must chill the dough for 24 hours to make them chewy?
No, this is a common misconception. The combination of cornstarch and brown sugar provides the necessary chewiness without requiring a long chill time.
How to keep these cookies soft for several days?
Store them in an airtight container with a slice of white bread. The cookies absorb moisture from the bread, keeping them velvety for up to 5 days.
How to cream the butter and sugars for the best lift?
Beat softened butter, coconut sugar, and brown sugar on medium high speed for 2 3 minutes. Stop once the mixture is pale and fluffy to ensure enough air is incorporated.
Can I use different candies instead of M&Ms?
Yes, any small candy coated chocolate works. If you enjoyed mastering the candy-to-dough ratio here, see how the same balance works in our chewy smores cookies.
How to freeze the cookie dough for later use?
Flash freeze scooped dough balls on a tray for one hour. Transfer them to a freezer bag and bake straight from frozen without thawing.
