Big Chewy M&M Cookies

Recently, I unearthed my Bake It Forward tin and did a little giveaway that sent it to a BoB reader. The winner requested M&M cookies, which I had surprisingly never baked. What a good excuse to make them!

I wanted to make these cookies a bit chewy and more than a bit big. This recipe is adapted from America’s Test Kitchen.

I only made a couple of changes to their recipe. First of all, obviously, I used M&Ms instead of chocolate chips. I used plain M&Ms, but I’d love to try these again with a different variety.

The other change I made was to make the cookies just a bit bigger. I used a 3-tablespoon cookie scoop to make giant cookies. If you make them smaller, keep in mind that you may need to adjust your baking time.

Before sending these cookies off to the giveaway winner, we had to sample a couple just to make sure they were good. They were. They really were. Completely unselfish of me, I know.

Big Chewy M&M Cookies


  • 2 cups plus 2 tablespoons all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3/4 cup unsalted butter, melted and cooled
  • 1 cup packed light brown sugar
  • 1/2 cup granulated sugar
  • 1 large egg
  • 1 large egg yolk
  • 2 teaspoons vanilla extract
  • 1 & 1/2 cups M&Ms


  1. Preheat oven to 325°F. Line baking sheets with parchment paper or silicone liners.
  2. Whisk together the flour, baking soda, and salt. Set aside.
  3. Using an electric mixer on medium speed, beat the butter, brown sugar, and sugar until smooth. Add the egg, egg yolk, and vanilla. Beat until combined.
  4. Reduce mixer speed to low. Gradually add the flour mixture, and mix just until combined. Stir in the M&Ms.
  5. Using 3 tablespoons of dough, roll the dough into balls. (Or, use a cookie scoop). Place onto prepared pans, leaving about 2 inches between cookies. Bake, one pan at a time, for 15-20 minutes, or until the edges are beginning to brown and the centers are still soft.
  6. Cool on pans for about 10 minutes. Serve warm or transfer to wire racks to cool completely.

  5. These look so pillowy and wonderful. I wish I was sinking my teeth into one right now!

  6. It looks yummy and it’s nice colorful! 🙂

  7. These look great and I’ve bought everything to make them but one question – do you leave the dough in balls or flatten them a bit before they go in the oven?

  8. I just made these cookies with red & green M & M’s for Christmas! They turned out really good! So happy!

  9. Really good recipe! Thank You!

  10. Did anyone else find the dough super sticky? It was so sticky for me to roll so I just scooped some in my Hand and dropped it on the tray. The dough did taste yummy though 🙂

  11. Absolute favorite kind of cookie! Can’t wait for the chewiness of these, knowing me ill use just a bit more chocolate chips than recommended. Gotta satisfy that sweet tooth (and these will!)

  12. What should I do with the cookie dough that is waiting for the oven? Leave it out or put it in the refrigerator?

  13. Can I substitute any kind of candy for the m&m’s, such as snickers, milky way or peanut m&m’s??

  14. Made these cookies yesterday. They only lasted for 2 days. Making a new batch as we speak. Best m@m cookies i’ve ever made!

  15. I know it’s been years since you posted this recipe, but I just baked these delicious cookies today. I used a 3TB scoop and baked them 6 to a sheet for 17 minutes. They came out perfect and I didn’t change a thing in your recipe.
    My only other comment would that the yield amount is wrong, at least if you use the 3TB scoop. I ended up with 18 delicious cookies.
