Perfect with a glass of cold milk after school treat for the kiddos. 

My kid, (the big one) meaning my husband, is infatuated with the mini M&M’s.  If it was up to him, they would be in every cookie batch I make, like these OMG! Soft-Batch Mini M&M & Chocolate Chip Cookies.

Peanut Butter M&M Cookies

Some tips…

If you want these to come out soft and chewy, don’t overbake these.  However, if you like a crunchier peanut butter cookie, bake them a couple minutes longer.  They are excellent either way!

If  you want them thick, when you ‘fork’ them, just press the fork down gently when criss-crossing, and they’ll come out thicker.

I used a medium scoop, 1 1/2 tablespoons worth, which makes a about a 3-inch cookie.  Thus, resulting in medium sized cookies.  If you make them smaller or bigger, adjust your time.

I used butter.  Butter makes them softer and who doesn’t like butter?  But if you want to use shortening, reduce the amount to 1/3 cup.

I used Jif peanut butter, which I use in most all my cookies.  If you use all-natural peanut butter, make your own, or use low-fat or low-salt peanut butter, the cookies won’t turn out like these.  Get the peanut butter to a creamy consistency before adding it to your cookie dough.

Cook Time 12 minutes
Course Dessert
Servings 24


  • ½ cup unsalted butter softened
  • ½ cup granulated sugar
  • ½ cup light brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • ¾ cup smooth peanut butter
  • 1 ⅓ cups All-Purpose Flour I used King Arthur
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 - 2 cups of mini semi-sweet or milk chocolate M&M's


  • Preheat the oven to 350°F. Lightly grease (or line with parchment) two baking sheets.
    Using mixer, beat together butter, sugars, egg, vanilla, and peanut butter until smooth.
    Add the flour, baking soda, and salt to the peanut butter mixture, beating gently until everything is well combined and fold in the mini M&Ms.
    Drop the cookie dough by tablespoonful or by using a 1 1/2 Tablespoon cookie scoop, onto the prepared baking sheets leaving 2" in between each cookie.
    Gently use a fork to flatten each cookie to about 1/2" thick, making a cross-hatch design.
    Bake the cookies for 12 to 16 minutes, until they're barely beginning to brown around the edges to get best results for soft and chewy peanut butter cookies. Bake longer for crunchy.  Remove them from the oven and let set to cool on baking sheet for 5 minutes to set up so they don't fall apart.
    Yield: about 2 dozen cookies.


You can add a little more flour - up to 2 tablespoons to 1/4 cup if you want a little denser cookie (no more!)

Recipe modified @ King Arthur Flour’s CLASSIC PEANUT BUTTER COOKIES


  1. I just came across this recipe and hope to add it to my Christmas cookie tray this year. One question – on the mini m&m’s, 1 to 2 cups is a big range. How much did you use in the photos? Thanks!

  2. I love using oats in cookies and peanut butter too! I’ve yet to try lavender though! Sounds wonderful in shortbread cookies! Thanks so much Ben and have a great weekend!!

  3. Agreed 100% – they are super cute! I cannot say I’m really passionate about cookies(except shortbread. And lvender. And with oats. And with peanut butter. Well I guess I’ve got a little passion after all), but the combination of peanut butter and m&m’s is so irresponsibly good!

  4. LOL! Sorry about that Laura, but I couldn’t stop at one…which that could probably coincide with all cookies made with butter! Thank you dear!!

  5. Ok, you had me at “peanut butter’ , why did you have to say “Can’t eat just One?” That is the ultimate cookie in my book, addictive and peanut butter-containing! Making these for sure! (And, I agree, it’s all about butter, too!) Thanks for the recipe!
