    M&M Cookies

    M&M Cookies are a basic sweet cookie dough with candied-covered chocolates folded in. They’re then baked until lightly browned around the outside edges but soft in the middle. My recipe uses more ingredients, like chocolate and nuts, to make them heartier and more delicious.

    This recipe originated at the Legends, a country club I worked at over 25 years ago. You can customize these cookies by removing additional chocolate, nuts, or peanut butter chips without changing the cookie dough recipe. If you do go this route, I would recommend doubling the amount of M&M’s used.

    Ingredients and Substitutions

    • Butter – I always use unsalted butter in my cooking and baking to control the sodium content.
    • Sugar – I used a combination of light brown and regular granulated sugar. You could also use all brown sugar instead of the combination. In addition, you can substitute light for dark brown sugar.
    • Eggs – Large eggs that are chilled or at room temperature work perfectly.
    • Vanilla – A good vanilla extract is best to use.
    • Flour – All-purpose flour is what’s needed for these M&M cookies. However, you can substitute it with bread flour.
    • Leavening Agents – I used a combination of baking powder and baking soda.
    • Salt – I always use coarse salt in my cooking and baking.
    • Chocolate — I used a combination of semi-sweet and white chocolate chips and chunks. You can use one or the other or a combination like I did.
    • Candy – You will need M&M’s for these cookies.
    • Nuts – This is optional, but I used walnuts in these cookies. However, you can also use pecans, cashews, or regular peanuts.
    • Peanut Butter Chips – This is also optional, but I like adding them for more peanut butter flavors.

    How to Make M&M Cookies

    1. Start by creaming some softened unsalted butter with brown and granulated sugar on medium speed for 5-7 minutes or until it’s light and fluffy.
    2. Add one large egg at a time until completely mixed in. In other words, don’t add the second egg until the first one is mixed in.

    3. Pour in your vanilla and continue to mix on medium speed.
    4. Mix the all-purpose flour, baking powder, baking soda, and salt in a separate large bowl until combined.

    5. Turn the speed down to low and add the dry ingredients to the stand mixer in 3 batches until mixed in.
    6. Remove the mixing bowl and fold the chocolate chips, M&M’s, peanut butter chips, and walnuts using a rubber spatula until incorporated.

    7. Ok, so the cookie dough is finished up, and now it’s time to scoop them onto cookie sheet trays lined with parchment paper. Like I said in the step-by-step video below, I like them to be bigger, so mine is 3 tablespoon scoops.
    8. Scoop them out from the dough onto a sheet tray lined with parchment paper about 4”-5” apart from each other, and then bake away at 350° for 16-18 minutes or until the edges start to turn light brown.

    Why Are My Cookies Flat?

    Overmixing — If you mix the dough too much, it can overbeat the ingredients, preventing them from reaching their full peak in the oven.

    The dough is too Hot — If your dough is too hot/warm, it’ll fall too fast in the oven and slowly create layers as it spreads out. Try chilling it after placing it on the sheet tray in the refrigerator for 10 minutes before baking.

    No Baking Powder – There are quite a few recipes that do not use baking powder.  I believe this ingredient is essential to tall, thick cookies.  If the recipe you love doesn’t have any of it, I’d add a teaspoon or 2.

    How to Make the Best Cookies

    • Brown Sugar – Brown sugar has a higher moisture content than plain sugar, ensuring these tasty treats will be moister and more flavorful.
    • Under Cooking – I’m not telling you to serve these up raw, but always go a few minutes under because once your cookies come out of the oven, they will continue to cook until cool; We call this carry overcooking.

    Make-Ahead and Storage

    Make-Ahead: You can make these up to 2 days ahead for freshness.

    How to Store: Add the M&M chocolate chip cookies to plastic bags and keep them at room temperature for up to 5 days or in the refrigerator for up to 7 days. The dough and baked cookies will freeze well, covered in a container or plastic wrap, for up to 3 months.

    chef notes + tips

    • On the sugar front, I like to combine brown and regular sugar, but you could absolutely use all light brown sugar.
    • Scrape the bowl of the standing mixer often to ensure all of the ingredients are being incorporated.
    • You can mix the final ingredients into the dough with the stand mixer, but they may break up quite a bit because of the torque from the mixer.
    • These are large, so I baked 6 on a tray at once, but If you prefer smaller cookies, please feel free to do so.
    • When making them, You should not flatten them with your finger or a spoon. They will flatten out as they bake at 350° and create layers as they spread out. When it does this, the cookies steam on the inside, making them moist.
