Do you realize how many different flavors of M&Ms there are out there?
Just curious, because until the other day when Zach came home from the grocery store with about 10 different colored M&M bags (because there’s obviously not enough sugar in my house already 😉), I had no idea.
I made these M&M Cookies with plain milk chocolate M&Ms, but now I’m looking forward to trying them with different flavors (so far, from trying them outside of a cookie, Caramel is a clear winner, White Chocolate is too sweet, and even though I was super resistant to trying Strawberry Nut it was surprisingly good).
Regardless of which variety of chocolate you choose to use, I think you’re going to love this easy, no-mixer required M&M Cookie Recipe. Let’s get started.
Why Do We Use Melted Butter Instead of Softened Butter?
Many cookie recipes call for softened butter and the ingredients direct you to cream your butter and sugars together. There’s nothing wrong with this technique, but I’ve found time and time again that creaming butter and sugar leads to cakier cookies, while using melted butter yields not only a chewier, softer cookie, but one that’s more buttery/more flavorful as well. Ever since first using this technique with my (“worst”) chocolate chip cookie recipe it’s become a default for most of the cookies that I share.
There are some drawbacks to using melted butter. Usually cookie dough made with melted butter requires chilling (as this M&M Cookie recipe does) to keep the cookies from spreading to much, but I’ve found the taste to be worth any extra time.
As I’ve also noted in this recipe and others, it’s really important that you not only melt your butter, but also let it cool back down to near room temperature. If you add your sugar while the butter is too hot, you can actually melt the sugar and end up with runny cookie dough that will never hold its shape in the oven, no matter how long you chill it.

How to Make M&M Cookies
M&M Cookie Recipe
- 1 cup butter melted and cooled at least 10 minutes (226g)
- 1 ¼ cup brown sugar* tightly packed (250g)
- ½ cup sugar (100g)
- 1 large egg + 1 egg yolk room temperature preferred*
- 1 ½ teaspoon vanilla extract
- 2 ¾ cups all-purpose flour (350g)
- 1 Tablespoon cornstarch
- ¾ teaspoon baking soda
- ½ teaspoon baking powder
- ¾ teaspoon salt
- 1 ½ cups M&Ms
- Combine your melted (and cooled) butter and sugars in a large bowl and stir until well-combined.
- Add egg, egg yolk, and vanilla extract and stir until combined.
- In a separate, medium-sized bowl, whisk together flour, cornstarch, baking soda, baking powder, and salt.
- Gradually add dry ingredients to wet and mix until combined.
- Use a spatula to stir M&M candies into the cookie dough
- Cover bowl with plastic wrap and transfer to the refrigerator to chill for at least 45 minutes.
- Preheat oven to 350F (175C) and line a cookie sheet with parchment paper.
- Once oven has preheated, remove your chilled cookie dough from the fridge and roll dough into approximately 2-Tablespoon-sized scoops. Roll gently to form a ball and place on prepared cookie sheet (space cookies at least 2" apart).
- Bake on 350F (175C) for 10-11 minutes, centers of the cookies may still seem slightly underbaked -- allow cookies to cool completely on cookie sheet to finish cooking there, this will help keep them nice and soft.
