These cookies are soft in the center, lightly crisped on the edges, and perfectly balanced between salty peanut butter and sweet chocolate. They’re easy to whip up and even easier to devour. M&Ms add both visual appeal and that delightful crunch in every bite. Best of all, they store well, freeze beautifully, and are a hit with kids and adults alike.

Can I Use Any Kind of M&Ms in These Cookies?

Absolutely! Peanut Butter M&Ms give these cookies their signature burst of nutty-chocolate flavor, but you can easily swap in classic Milk Chocolate M&Ms, Crispy M&Ms, or even seasonal varieties. Just keep in mind that using peanut or almond M&Ms will slightly alter the texture and size of the cookies. If you’re going for the classic chewy cookie feel, the peanut butter variety is the best choice.

The ingredients here are all about creating a soft and chewy cookie that holds its shape and flavor beautifully. The combination of peanut butter, sugars, and M&Ms creates a perfect harmony of salty, sweet, and crunchy.

Step 1: Cream the Butter and Sugars

In a large mixing bowl, beat the unsalted butter, creamy peanut butter, brown sugar, and granulated sugar together until light and fluffy. This step builds the base of your dough and helps ensure a soft texture.

Step 2: Add Wet Ingredients

Mix in the egg and vanilla extract until fully incorporated. This adds structure and flavor to your cookies.

Step 3: Combine Dry Ingredients

In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this mixture to the wet ingredients, mixing just until a dough forms.

Step 4: Fold in the Good Stuff

Gently fold in the Peanut Butter M&Ms and mini chocolate chips. Try not to overmix to keep the M&Ms whole and the dough tender.

Step 5: Scoop and Bake

Preheat your oven to 350°F (175°C). Use a cookie scoop to place even rounds of dough onto a baking sheet lined with parchment paper. Leave space between each cookie. Bake for 9–11 minutes, or until the edges are just starting to turn golden.

Step 6: Cool and Enjoy

Let the cookies cool on the pan for 5 minutes before transferring to a wire rack. They will firm up as they cool, leaving you with a perfectly chewy bite every time.
