Ingredients for M&M Cookies

Makes about 30 cookies

• 1 cup (226 g) unsalted butter, softened
• ¾ cup (165 g) packed light brown sugar
• ½ cup (100 g) granulated sugar
• 2 large eggs, room temperature
• 2 teaspoons vanilla extract
• 2¼ cups (280 g) all-purpose flour
• 1 teaspoon baking soda
• ½ teaspoon salt
• 1½ cups of M&M’s, plus an extra ¼ cup for topping

How to Make M&M Cookies

Step 1: Prepare the Cookie Dough

Preheat the oven to 175°C (350°F) and line two baking trays with parchment paper. In a large bowl, beat the softened butter with the brown and white sugars for two to three minutes, until light and creamy. Beat in the eggs one at a time, then stir in the vanilla.

In a separate bowl, whisk together the flour, baking soda, and salt. Add the dry ingredients to the wet ingredients and mix on low speed until well combined. Stop mixing once the dry ingredients are incorporated. Overmixing will make tough cookies.

Step 2: Fold in the M&M Candies

Gently fold 1½ cups of M&M’s into the batter using a flat spatula. Stirring by hand helps prevent the shells from breaking and the colors from mixing. Cover the bowl and refrigerate the batter for 30 minutes. This step helps prevent the batter from spreading and results in thicker cookies.

Step 3: Shape and Bake the Cookies

Shape the dough into balls about the size of one and a half tablespoons, and place them on prepared baking trays, leaving 5 cm between each ball. Gently press some extra M&M’s onto the surface of each ball so the cookies look perfect, just like they come from a bakery.

Bake for 10 to 12 minutes, until the edges are set and lightly golden but the centers still look slightly soft. Let the cookies cool on the baking sheet for 5 minutes, then move them to a wire rack.

Tips for the Best M&M Cookies

• Measure the flour correctly. Spoon it into your measuring cup and level it off, or use a kitchen scale. Too much flour makes dry cookies.
• Use softened, not melted, butter. It should give slightly when pressed but still hold its shape.
• Don’t skip the chill time. Even 30 minutes makes a visible difference in thickness.
• Pull them out early. Cookies keep cooking on the hot pan, so take them out while the centers look a little underdone.
• Press candies on top. Mixed-in M&M’s tend to sink, so adding a few on top guarantees the colorful look.
• Try mini M&M’s for more candy in every bite and a slightly more delicate texture.

How to Store M&M Cookies

Allow the cookies to cool completely, then store them in an airtight container at room temperature for up to 5 days. Layer parchment paper between them if you’re stacking, so the candy doesn’t stick.

Can You Freeze M&M Cookies?

Yes. M&M’s cookies freeze very well, whether baked or in dough form.

• Baked cookies: Freeze in a single layer on a tray until solid, then transfer to a freezer bag for up to 3 months. Thaw at room temperature.
• Cookie dough: Scoop the dough into balls, freeze them on a tray, then store in a freezer bag for up to 3 months. Bake straight from frozen, adding 1 to 2 minutes to the bake time.

M&M Cookies FAQs

How Do You Keep M&M Cookies Soft?

Slightly underbake them, since they firm up as they cool. Brown sugar helps hold moisture, and storing the cookies in an airtight container with a slice of bread keeps them soft for days.

Why Do M&M Cookies Spread Too Much?

The most common causes are butter that’s too warm or melted, skipping the chill time, or baking on a hot pan. Too little flour can also cause spreading. Measure carefully, chill the dough, and let your baking sheets cool between batches.

Can I Use Different M&M Colors in These Cookies?

Absolutely. Use red and green for Christmas, orange and brown for Halloween, or pastels for spring. You can also match team colors or party themes. The recipe works the same with any color mix.
