Peanut Butter M&M cookies are the ultimate blend of nutty richness and chocolatey bursts These cookies are soft but sturdy with colorful M&Ms peeking out of every chewy bite There is just enough salt to balance the sweet and the dough comes together quickly whenever a craving hits
I started baking these cookies for holiday trays but they became an all year favorite Whenever a new bag of M&Ms comes out the kids beg to mix them in and make a fresh batch
Ingredients
- Salted butter: brings rich flavor and chewy texture If using unsalted add a generous pinch of salt
- Creamy peanut butter: gives the cookies a deep nutty taste Choose a no stir variety for best results
- Pure vanilla extract: brightens and elevates the dough Use real vanilla for the best aroma
- Brown sugar: keeps the cookies moist and adds caramel notes Dark brown sugar gives extra depth
- Granulated sugar: balances out the brown sugar and adds crisp edges Look for fine crystals that blend in easily
- Large eggs plus yolk: help make the dough rich and bind everything together Room temperature eggs mix in smoother
- All purpose flour: forms the cookie’s base Measure it carefully for softness
- Baking soda and baking powder: give lift and tenderness Always check freshness for fluffy cookies
- Peanut butter mini M&Ms or regular M&Ms: add pops of color and melt in your mouth bursts Choose fresh for best texture
- Mini chocolate chips: dot each cookie with gooey chocolate pools
- Flaky sea salt for sprinkling: is optional but makes flavors pop Add just a touch after baking if you like that sweet and salty finish
Instructions
- Prepare the oven and baking sheets:
- Preheat your oven to 350 degree Fahrenheit Lay out baking sheets and line with parchment paper or a silicone mat for easy cookie removal
- Cream the butter and sugars:
- Place softened salted butter brown sugar and granulated sugar in a large mixing bowl Using a stand mixer with paddle attachment or an electric mixer beat for two to four minutes until the mixture is light and fluffy This builds that soft chewy texture
- Blend in peanut butter and wet ingredients:
- Add creamy peanut butter pure vanilla extract two whole eggs and one egg yolk to the bowl Scrape down the sides and mix until everything is evenly incorporated and satiny
- Mix the dry ingredients:
- In a separate bowl whisk together the all purpose flour baking soda and baking powder until completely blended This ensures even lift throughout your cookies
- Combine wet and dry dough:
- Slowly add the flour mixture to your wet mixture Stir just until a dough forms Do not overmix or you risk tough cookies
- Fold in M&Ms and chocolate chips:
- Pour the mini peanut butter M&Ms and mini chocolate chips into the dough Use a spatula to fold them in so they stay whole and are evenly distributed
- Scoop and shape the dough:
- Scoop out large rounds of dough about three tablespoons each and place two inches apart on prepared baking sheets Gentle spacing lets them spread perfectly
- Bake to golden perfection:
- Slide the cookies into your hot oven Bake for twelve to thirteen minutes Keep an eye on the edges as they should look just golden with centers slightly underdone for soft cookies
- Finish and cool:
- If you love a sweet salty finish sprinkle warm cookies with flaky sea salt Let them cool for a few minutes on the sheet before transferring to a wire rack for complete cooling Peeking M&Ms add to the fun

The M&Ms are my all time favorite because they add so much color and crunch My kids love to help mix in the candies and press a few extra on top before baking Last Christmas we mixed red and green for a festive cookie plate
