A cookie that’s vibrant, chocolate-studded, and chewy in all the right ways is a small joy worth baking.
These Soft and Chewy M&M Cookies hit that sweet spot between nostalgia and indulgence
Each bite offers a perfect balance of sweetness, color, and texture—soft in the center with just the right edges.
I love how these cookies feel festive without any fuss.
They’re easy enough for a weekday treat but impressive enough to serve at a gathering.
Every time I make them, I notice how the M&Ms soften slightly while keeping their color, giving each cookie a playful, bakery-style look.
Why This Recipe Works So Well
After years of testing cookie recipes, I’ve learned that the right balance of structure, moisture, and sweetness is everything
The combination of brown sugar and granulated sugar, plus a touch of cornstarch, ensures a dough that stays soft and tender even after cooling.
Adding a yolk to the eggs gives a chewy center without making the cookies cakey.
Meanwhile, the M&Ms and chocolate chips provide color, crunch, and those melty pockets of chocolate that make every bite memorable.
This recipe consistently yields cookies that are soft, slightly puffy, and delightfully satisfying.
Ingredients Needed for the Recipe
Using quality ingredients and measuring them correctly is key to achieving perfect cookies. Each ingredient has a role that goes beyond flavor:
- All-Purpose Flour: Forms the cookie’s structure. Too much flour will make cookies dense, so proper measurement is essential.
- Cornstarch: Adds tenderness and prevents a tough bite, creating a soft, almost pillow-like texture.
- Baking Soda & Fine Sea Salt: Baking soda allows controlled spreading and helps edges brown, while salt balances sweetness and enhances overall flavor.
- Unsalted Butter (cool room temperature): Helps cookies spread correctly and creates a delicate, tender crumb. Butter that’s too soft or melted can flatten cookies too much.
- Light Brown Sugar & Granulated Sugar: Brown sugar adds moisture and caramel-like depth, while granulated sugar produces crisp edges for a perfect contrast.
- Vanilla Extract, Large Eggs & One Egg Yolk: Eggs provide structure and richness, while the extra yolk ensures chewiness and a slightly more tender center.
- M&M Candies & Semisweet Chocolate Chips: M&Ms offer colorful crunch, while chocolate chips melt into soft pockets of chocolate, enhancing each bite.
The Heart of the Matter: Measuring Flour
Flour measurement is the most common reason cookies turn out dry or dense.
The best method is using a digital scale for precision.
If you’re using measuring cups, fluff the flour in its container, spoon it into the cup, and level it off.
These small adjustments ensure your cookies stay soft and chewy instead of hard and dry.
How to Make Soft and Chewy M&M Cookies?
Step 1: Prep and Preheat
Preheat your oven to 350°F (175°C) and line your baking sheets with parchment paper. This simple step ensures even baking, prevents over-browning, and makes cleanup effortless.
Step 2: Combine the Dry Ingredients
In a medium bowl, whisk flour, cornstarch, baking soda, and salt. Whisking distributes the leaveners and cornstarch evenly, ensuring every cookie rises and bakes consistently.
Step 3: Cream the Butter and Sugars
Beat the butter and sugars on medium-high for 2–3 minutes until light and fluffy. This incorporates air, which contributes to a tender, chewy texture. Properly creamed butter is the difference between soft cookies and flat, greasy ones.
Step 4: Add the Wet Ingredients
Add the vanilla, eggs, and extra yolk one at a time, beating well after each addition. Scrape the sides of the bowl frequently to create a smooth, emulsified dough that will bake evenly.
Step 5: Bring the Dough Together
Mix in the dry ingredients on low speed until just combined. Then fold in most of the M&Ms and all the chocolate chips, leaving a few for topping. Folding gently preserves the cookies’ tender texture while keeping the candy intact.
Step 6: Scoop and Garnish
Use a large cookie scoop (about 3 tablespoons) to portion the dough. Press a few reserved M&Ms on top for a polished, professional look. Scooping ensures even-sized cookies that bake uniformly.
Step 7: Bake to Perfection
Bake 11–13 minutes. Cookies are ready when edges are golden, but centers still appear soft. They’ll continue to set on the hot pan, keeping the centers chewy.
Step 8: Cool and Serve
Let the cookies rest on the sheet for at least 5 minutes before transferring to a wire rack. This helps them set while retaining softness. Eating too soon can give a slightly under-baked texture.
The Magic of a Chill
Chilling the dough for 24–72 hours transforms the flavor and texture. The flour fully hydrates, and the brown sugar deepens the caramel notes. Chilled dough produces thicker, chewier cookies with richer flavor—a tip I swear by for special occasions.
Tips for the Best Cookies
- Butter Temperature Matters: Cool, slightly firm butter yields the perfect spread.
- Don’t Overbake: Slightly underbaked centers finish setting as they cool, keeping the cookies soft.
- Use a Cookie Scoop: Ensures uniform size, baking consistency, and quick portioning.
Choosing Your M&Ms
This recipe is flexible. Classic milk chocolate M&Ms are perfect, but mini M&Ms give more even candy distribution.
Peanut M&Ms introduce a salty crunch, and seasonal or themed colors can make the cookies festive. The dough adapts well to creative variations.
Storing Your Masterpiece
Store completely cooled cookies in an airtight container at room temperature.
For extra softness, tuck in a slice of bread or a flour tortilla—this keeps them soft for up to 3 days without changing the flavor.
Freezing for Future Joy
The dough freezes exceptionally well. Scoop balls onto a tray, freeze until solid, then transfer to a freezer bag.
Bake straight from frozen, adding 1–2 minutes to the baking time. Having ready-to-bake dough is a lifesaver for spontaneous cookie cravings.
These Soft and Chewy M&M Cookies are more than a nostalgic treat—they’re a reliable, bakery-style cookie you can make anytime.
With vibrant candy, pockets of melted chocolate, and perfectly chewy centers, every bite delivers satisfaction.
Whether for a treat-yourself moment or a crowd-pleasing dessert, these cookies rarely last long once they’re on the table.

ingredients
Instructions
-
If baking the cookie dough immediately, preheat the oven to 350°F. Line baking sheets with parchment paper.
-
In a medium bowl, whisk together the flour, cornstarch, baking soda, and salt.
-
In a large mixing bowl, use an electric stand or hand mixer fitted with the paddle attachment to beat the butter, brown sugar, and granulated sugar on medium-high speed until light and fluffy, about 2 to 3 minutes. Scrape down the sides and bottom of the bowl before adding in the vanilla, eggs, and egg yolk, beating well after each addition, and scraping down the bowl as needed.
-
Slowly beat in the flour mixture. Stir in the M&M candies and chocolate chips with a rubber spatula, reserving about 1/4 cup M&Ms to garnish each cookie dough ball.
-
OPTIONAL CHILL TIME: For extra soft, chewy, and flavorful cookies, wrap dough balls in plastic wrap and refrigerate for at least 24 hours but no more than 72 hours. Bake directly from the fridge, adding a minute to the bake time if needed.
-
Using a large spring-loaded cookie scoop, divide the dough into 3-tablespoon-sized balls and drop onto prepared baking sheets. Press a few of the saved M&M candies into the top of each ball of dough.
-
Bake at 350°F for about 11 to 13 minutes, or until golden brown but still ever so slightly wet looking on top for soft cookies. Cool for 5 minutes before removing to a cooling rack to cool completely before serving for the chewiest texture.
-
Cookies can be stored in an airtight container at room temperature for up to 3 days. Store with a tortilla or slice of white bread to keep soft.

Note
- Flour tip: Always measure flour by weight or use the spoon-and-level method to avoid dry, dense cookies.
- Cornstarch is key: Don’t skip it—it’s the secret to ultra-soft, chewy texture.
- Don’t overbake: Cookies should look slightly wet in the center when you pull them out—they’ll finish cooking on the hot pan.
- Butter temperature matters: Use butter at cool room temperature (~67°F) to prevent flat cookies.
- Chill for best results: 24–72 hours in the fridge deepens flavor and improves texture.
- Storage hack: Keep cookies soft by storing with a tortilla or slice of bread in an airtight container.
