Ingredients:
- ½ cup unsalted butter, for browning
- ½ cup plus 2 tablespoons packed light brown sugar
- 2 tablespoons granulated sugar
- 1 large egg, at room temperature
- 1 teaspoon pure vanilla extract
- 1⅓ cups all-purpose flour, spooned and leveled
- ½ teaspoon baking soda
- ¼ teaspoon fine sea salt
- ½ cup milk chocolate chips, plus extra for topping
- ½ cup milk chocolate peanut butter M&Ms, plus extra for topping
- 8 tablespoons creamy peanut butter (approximately 1 tablespoon per cookie, divided for filling)
- Extra milk chocolate chips for garnish
- Extra milk chocolate peanut butter M&Ms for garnish
- Pretzel pieces for garnish (optional)
Preparing the Dough
Step 1: Brown the Butter
This is where we build a foundational layer of nutty, complex flavor for our Peanut Butter M&M Cookies. Place the ½ cup of unsalted butter in a light-colored saucepan over medium heat. Watch it carefully as it melts and begin extracts to foam. You’ll notice little brown bits forming at the bottom of the pan and a wonderful toasty aroma will fill your kitchen. This process, called browning the butter, takes about 5-8 minutes. Once it smells nutty and has amber-brown flecks, immediately remove it from the heat and pour it into a heatproof bowl to stop the cooking. This prevents it from burning. Let the browned butter cool slightly for about 10-15 minutes, or until it’s warm but not hot.
Step 2: Cream the Sugars and Butter
In a large mixing bowl, combine the slightly cooled browned butter with the ½ cup plus 2 tablespoons of packed light brown sugar and the 2 tablespoons of granulated sugar. Using an electric mixer on medium speed, cream these ingredients together until the mixture is light and fluffy. This process incorporates air, which contributes to the cookie’s texture. Scrape down the sides of the bowl occasionally to ensure everything is evenly mixed. This should take about 2-3 minutes.
Step 3: Incorporate Wet Ingredients
Add the room-temperature large egg and the 1 teaspoon of pure vanilla extract to the creamed sugar and butter mixture. Continue mixing on medium speed until everything is well combined and the egg is fully incorporated. The mixture might look a little curdled at this stage, which is perfectly normal. Make sure to scrape down the sides and bottom of the bowl one last time to ensure no pockets of unmixed ingredients remain.
Step 4: Combine Dry Ingredients and Add to Wet
In a separate medium bowl, whisk together the 1⅓ cups of all-purpose flour, ½ teaspoon of baking soda, and ¼ teaspoon of fine sea salt. Whisking the dry ingredients first helps to distribute the leavening agent (baking soda) and salt evenly, preventing pockets of salty or flat cookies. Gradually add this dry ingredient mixture to the wet ingredients in the large mixing bowl. Mix on low speed, or stir with a spatula, just until the flour is incorporated and no dry streaks remain. Be careful not to overmix the dough at this stage, as overmixing can lead to tough cookies.
Adding the Stars of the Show
Step 5: Fold in the Goodies
Now for the fun part! Gently fold in the ½ cup of milk chocolate chips and the ½ cup of milk chocolate peanut butter M&Ms into the cookie dough using a spatula. You want to distribute them evenly throughout the dough, but again, avoid overmixing. Some of the M&Ms might break a bit, which is fine and adds lovely streaks of color and flavor.
Shaping and Baking the Peanut Butter M&M Cookies
Step 6: Chill the Dough and Prepare for Baking
This step is crucial for achieving perfectly shaped cookies that don’t spread too much during baking. Cover the bowl with plastic wrap and refrigerate the dough for at least 30 minutes. While the dough chills, preheat your oven to 350°F (175°C). Line baking sheets with parchment paper or silicone baking mats to prevent sticking and ensure even baking. Once the dough is chilled, scoop out portions of dough, about 1.5 tablespoons each, and roll them into balls. Gently press a small indentation into the center of each dough ball. This is where we’ll place our delightful peanut butter filling.
Step 7: Fill and Top the Cookies
Take about 1 tablespoon of creamy peanut butter and gently place it into the indentation you made in each cookie dough ball. Now, carefully bring the edges of the dough up and around the peanut butter to enclose it completely, forming a well-senon-alcoholic aled ball. This creates a gooey peanut butter center. Place these filled cookie dough balls onto your prepared baking sheets, spacing them about 2 inches apart. For extra visual appeal and flavor, press a few extra milk chocolate chips and milk chocolate peanut butter M&Ms onto the top of each cookie. If you’re feeling adventurous and want a salty crunch, you can press a few pretzel pieces onto the top as well.
Step 8: Bake to Perfection
Bake the cookies in the preheated oven for 10-12 minutes, or until the edges are golden brown and the centers are still slightly soft. The cookies will continue to set as they cool. Avoid overbaking, as this will result in dry, crum extractbly cookies. Once baked, let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. This resting period allows the cookies to firm up properly. Enjoy these decadent Peanut Butter M&M Cookies warm or at room temperature!

Frequently Asked Questions:
Q1: How can I make my Peanut Butter M&M Cookies softer?
To achieve softer cookies, be careful not to overbake them. They should look slightly underdone in the center when you take them out of the oven; they will continue to cook and firm up as they cool on the baking sheet. Using brown sugar in place of some of the granulated sugar also contributes to a chewier and softer texture.
Q2: Can I use different types of M&Ms?
Absolutely! While the classic Peanut Butter M&M Cookies use standard M&Ms, feel free to experiment. Peanut Butter M&Ms would be a natural fit, or you could try seasonal M&Ms like red and green for holidays. Even plain M&Ms can offer a fun burst of color and sweetness.
