Mint Chocolate M&M Cookies are meant for the serious mint and chocolate lover. Loaded with chocolate mint candy, and packed with cocoa, these cookies are super moist and chewy! Don’t care for mint? You can use your favourite M&M flavour and use vanilla extract instead of peppermint!

Back when I first met John, I wish I had known that the key to winning his affection was to just offer him a big bag of M&Ms. And, if those M&Ms happen to be mint, then his affection would have been mine immediately! He is the reason I have decided to include Mint Chocolate M&M Cookies into this series.
Truth be told, it was him who initiated contact with me via an online dating app. He will deny this of course, but I have a screen capture of it and I can post it here, but a Lord needs to keep some things a secret!
Alas, this Mint Chocolate M&M Cookie recipe isn’t about how Harry met Sally, it’s about Christmas and candies and chocolate and mint and cookies and chocolate; did I mention candies and mint?

DON’T LIKE MINT?
Excuse me? We can’t be friends! I’m kidding! McKenna is not a fan of mint either unless it’s in ice cream. In fact, when I told her that these cookies were mint, she screwed up her nose, mumbled something about me ruining everything and walked away.
Until a few years ago, I wasn’t a fan of things that were minty. Truthfully, I’m still a little picky when it comes to how much mint I can tolerate. I can eat little bit of mint, but I’m not about to eat an entire peppermint patty!
If you don’t like mint, it’s as simple as substituting it for vanilla extract. Of course the flavour of the cookie will change, but the strength of the mint in the cookie as a whole will be much less powerful.

MORE CHRISTMAS COOKIE RECIPES!
Did you know that I’ve been posting a 24 Cookies of Christmas series for a few years now? There are over 100 Christmas cookie recipes that you can find right here at Lord Byron’s Kitchen! To make it easier to find, I have created a page for each series. Just click on the image below and you’ll find the full series for that volume all one page!
WILL OTHER M&M FLAVOURS WORK TOO?
Yes! One of the things I love about M&Ms the most is that they have a team of marketing geniuses working behind the scenes. They make a colour for just about any holiday you can think of. Plus, there’s a new flavour every few months (or so it seems!)
For this particular cookie, you can use regular chocolate or peanut M&Ms, but make them extra special and extra festive by buying the holiday-themed colours. At Christmastime, you can find M&Ms in different shades of green, you can find red, white, and green, and even just red and white.
I used M&M Crunch Mint, but you can use the Dark Chocolate Mint M&Ms too. I live in Canada where M&M flavours are limited, but I will often travel across the border into Buffalo to find baking supplies. Walmart in the states has more flavours of M&Ms than I can count! That’s where I found the crunch mint flavour.

MORE CHRISTMAS CONFECTIONS!
In some cases, we want more than a cookie. That’s why I have two more Christmas-themed collections you might want to consider. The first, is my 12 Bundt Cakes of Christmas, and the second is my 12 Biscotti of Christmas. Click on the image below to see each collection all on one page with links to each recipe!
STORING, PACKAGING, AND FREEZING
These cookies will stay fresh for about 3-5 days in a covered container and in a cool place. But, if you plan to freeze these cookies, use a food-safe container that can be frozen. You’ll want to ensure a very tight fitting lid too. (I use these quite often when freezing baked goods.) I like to place a sheet of plastic wrap over the top of the container before pushing the lid on. This helps to create a better seal. The goal is to keep all of that cookie freshness locked in!
You can freeze these cookies for up to three months. They will come out of the freezer looking just like they did when you put them in there. Once you thaw them, they will taste just as fresh as the day you first made them. When thawing, place the cookies onto a wire cooling rack in a single layer. Wait about 20 minutes or so and they will be perfectly thawed and ready to devour!

CONCLUSION:
Whether you use mint M&Ms or not, at the end of all of this mint and M&M talk, you’re going to be left with a large, thick, and chewy, chocolaty cookie which will soon become one of your favourites.
These are completely festive and a perfect addition to a Christmas cookie tin or cookie exchange. I love the bright green colour against the deep, cocoa brown. Make them ahead of time and freeze them. They will last in your freezer for up to three months!

I hit Buffalo as well, for grocery shopping – Aldi and Walmart and Trader Joes for the win! And then there’s Joanns … oh my 🙂 I don’t think I’ll be able to get there before Christmas, but I’m pretty sure we’ll have holiday M&Ms here – hopefully they’re mint flavoured! Our oldest son *loves* chocolate mint so this is the perfect recipe to make him a gift from mom – yours look fantastic, and that vintagey handled bowl they’re displayed in, is awesome!

Thank you, Sandra. I got that galvanized bowl with the handle from Hobby Lobby. I think it was less than $15. There are often mint flavoured M&Ms to be found here in Canada around Christmastime. I’ve found them at Bulk Barn before. 🙂
