Can You Substitute M&Ms for Chocolate Chips in Cookies?
Many bakers wonder if they can swap chocolate chips for M&Ms in cookies. The short answer is yes, but there are a few key differences to keep in mind when making this substitution.
Chocolate Chips vs. M&Ms – What’s the Difference?
Both ingredients add rich chocolate flavor, but they behave differently in cookies:
Feature | Chocolate Chips | M&Ms |
---|---|---|
Melting Point | Melt evenly into the dough | Stay intact due to candy shell |
Texture | Soft, smooth chocolate pockets | Crunchy outer shell with chocolate inside |
Appearance | Blends into the dough | Colorful and vibrant |
While M&Ms don’t melt the same way chocolate chips do, they add a unique crunch and a pop of color that make cookies look more festive.
How to Substitute M&Ms for Chocolate Chips
If you want to replace chocolate chips entirely, simply use an equal amount of M&Ms in the recipe. However, for best results, try this ratio:
- ¾ cup M&Ms + ¼ cup chocolate chips – Keeps the crunch while ensuring gooey chocolate pockets.
Another tip is to use mini M&Ms if you want a more even distribution throughout the cookie dough.
Why Do My M&M Cookies Come Out Flat? Troubleshooting Tips

Baking cookies should be easy, but sometimes you end up with flat, crispy cookies instead of soft, chewy ones. Here are the most common reasons why M&M cookies spread too much and how to fix them.
Common Reasons & How to Fix Flat Cookies
Problem | Possible Cause | Solution |
---|---|---|
Cookies spread too much | Butter is too soft or melted | Use room temperature butter, not melted |
Thin & crispy texture | Too much sugar or flour imbalance | Stick to accurate measurements |
M&Ms sink to the bottom | Dough is too soft | Chill dough for 30 minutes before baking |
Hard cookies | Overbaking | Remove when edges are golden but centers are soft |
Pro Tip for Thick Cookies
To get thicker, chewier M&M cookies, refrigerate the dough for at least 30 minutes before baking. Chilling solidifies the fat in the butter, preventing cookies from spreading too much in the oven.
Bonus Trick: Instead of mixing all the M&Ms into the dough, press a few extra on top of each cookie before baking for that classic bakery-style look.
How Do M&Ms Not Melt in Cookies?
Unlike regular chocolate chips, M&Ms hold their shape when baked. This is because of the hard candy shell, which acts as a protective layer that prevents them from completely melting.
Why M&Ms Stay Intact in Cookies
- The candy coating insulates the chocolate, preventing it from fully melting.
- The chocolate inside does soften, giving a delightful mix of crunch and gooeyness.
How to Keep M&Ms from Getting Too Hard in Cookies
If you want to ensure that your M&Ms stay soft and don’t get too crunchy in the oven, try these tips:
- Mix M&Ms into the dough gently to avoid breaking them.
- Use a mix of regular and mini M&Ms for better texture.
- Don’t overbake the cookies – the longer they bake, the harder the candy shell may get.
- Add extra M&Ms on top after baking if you want a vibrant look without affecting texture.
M&Ms add not just flavor but also visual appeal, making these cookies fun for kids, parties, and holidays.
Should You Refrigerate M&M Cookie Dough?
Refrigerating cookie dough is one of the best-kept secrets for making thicker, chewier, and more flavorful cookies. But is it necessary for M&M chocolate chip cookies? The answer is yes! While you can bake cookies right away, chilling the dough has several benefits.
Why Chilling Dough Improves Cookies
Refrigerating M&M cookie dough for at least 30 minutes before baking can:
- Prevent Cookies from Spreading Too Much – Chilled dough is firmer, so cookies hold their shape better.
- Enhance Flavor – The resting period allows the flour to absorb moisture and deepens the vanilla and buttery flavors.
- Create a Chewier Texture – Cold dough takes longer to spread in the oven, leading to a soft and chewy center with slightly crispy edges.
How Long Should You Refrigerate M&M Cookie Dough?
Chill Time | Effect on Cookies |
---|---|
0 minutes | Soft dough, cookies spread more |
30 minutes | Slightly thicker cookies with better texture |
2-3 hours | Chewy, flavorful cookies with a bakery-style look |
Overnight (8+ hours) | Deepens flavors, enhances chewiness |
Can You Bake M&M Cookies Without Chilling the Dough?
Yes, but the cookies will likely spread more and be thinner. If you’re short on time, try refrigerating for at least 15-20 minutes to help firm up the dough.
Freezing Cookie Dough for Later
M&M cookie dough freezes well! Follow these steps for make-ahead cookies:
- Scoop dough into balls and place them on a baking sheet.
- Freeze until solid, then transfer to an airtight container or zip-top bag.
- When ready to bake, place frozen dough balls on a baking sheet and bake directly from frozen, adding 2-3 extra minutes to baking time.
If you want perfect, thick, and chewy M&M cookies, chilling the dough is worth the wait!
Storing & Freezing Chocolate Chip M&M Cookies

Once you’ve baked a batch of chocolate chip M&M cookies, the next challenge is keeping them fresh and delicious for as long as possible. Proper storage ensures that your cookies stay soft and chewy rather than dry and stale.
How to Store Baked M&M Cookies
Storage Method | How Long Cookies Stay Fresh | Tips |
---|---|---|
Room Temperature | 5-7 days | Keep in an airtight container |
Refrigerator | Up to 2 weeks | Store in a sealed bag for best results |
Freezer | Up to 3 months | Freeze in layers with parchment paper in between |
Best Way to Store Cookies at Room Temperature
For cookies to stay soft and chewy:
- Store them in an airtight container at room temperature.
- Add a slice of bread to the container – the cookies absorb moisture from the bread, keeping them fresh longer.
- Keep cookies away from direct sunlight and heat, which can make M&Ms sweat and lose their crunch.
How to Freeze M&M Cookies
Freezing cookies helps them last longer while preserving texture and flavor. Here’s how to do it:
- Allow cookies to cool completely after baking.
- Layer cookies with parchment paper between them to prevent sticking.
- Store in a freezer-safe container or zip-top bag.
- When ready to eat, thaw cookies at room temperature or warm in the microwave for 10-15 seconds for a fresh-from-the-oven taste!
Should You Freeze Cookie Dough or Baked Cookies?
- Freezing dough: Best for fresh-baked cookies anytime.
- Freezing baked cookies: Great for meal prepping or gifting.
Proper storage keeps M&M chocolate chip cookies fresh, chewy, and delicious long after they’re baked!
