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 peanut butter M&Ms, plus extra for topping
- 8 tablespoons creamy peanut butter (divided, 1 tablespoon per cookie, for stuffing)
- Extra milk chocolate chips for garnish
- Extra peanut butter M&Ms for garnish
- Pretzel pieces for garnish (optional)
Browning the Butter
The first step to achieving an incredibly rich and nutty flavor in these Peanut Butter M&M Cookies is to brown the butter. This process unlocks complex toffee-like notes that regular melted butter simply can’t replicate. Place your ½ cup of unsalted butter in a light-colored saucepan over medium heat. As the butter melts, it will begin extract to foam. Continue to cook, swirling the pan occasionally, and keep a close eye on it. You’ll notice tiny brown bits starting to form at the bottom of the pan, and the aroma will change from milky to a delightful nutty scent. This usually takes about 5-7 minutes. As soon as the butter turns a lovely golden brown and smells fragrant, immediately remove it from the heat and pour it into a heatproof bowl. This stops the cooking process and prevents the butter from burning. Let it cool slightly while you prepare the dry ingredients.
Creaming the Sugars and Wet Ingredients
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 (or a sturdy whisk and some elbow grease), cream these together until the mixture is light, fluffy, and well combined. This aeration is crucial for the cookies’ texture. Next, add the room temperature large egg and the 1 teaspoon of vanilla extract. Beat again until everything is thoroughly incorporated. It’s important that your egg is at room temperature because it emulsifies better with the other ingredients, leading to a smoother cookie dough. If your egg is cold, you can quickly warm it by placing it in a bowl of warm water for about 5 minutes.
Incorporating the Dry Ingredients
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 together ensures that the leavening agent (baking soda) and salt are evenly distributed throughout the flour, preventing pockets of saltiness or uneven rising in your cookies. Now, gradually add the dry ingredients to the wet ingredients in the large mixing bowl. Mix on low speed or by hand until just combined. Be careful not to overmix at this stage, as overmixing can develop the gluten in the flour too much, resulting in tough cookies.
Adding the Mix-ins and Preparing for Stuffing
Gently fold in the ½ cup of milk chocolate chips and the ½ cup of peanut butter M&Ms using a spatula. Reserve any extra chocolate chips and peanut butter M&Ms you might want for topping later. At this point, the dough will be quite thick. Now comes the fun part – creating the peanut butter core! Divide your cookie dough into 8 equal portions. For each portion, flatten it in the palm of your hand to create a small disc. Place about 1 tablespoon of creamy peanut butter in the center of the disc. Carefully bring the edges of the dough up and around the peanut butter, sealing it completely to create a dough ball with a peanut butter center. Ensure there are no gaps or leaks, as this will cause the peanut butter to ooze out during baking. You can then roll these dough balls gently between your hands to make them smooth.
Baking and Garnishing
Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper to prevent sticking and ensure even baking. Place the peanut butter-stuffed dough balls on the prepared baking sheets, leaving about 2 inches of space between each cookie to allow for spreading. If you’re aiming for a beautiful presentation, now is the time to add your garnishes. Press a few extra milk chocolate chips and peanut butter M&Ms onto the tops of the dough balls. For an extra crunch and salty contrast, you can also press a few small pretzel pieces into the tops. Bake for 10-12 minutes, or until the edges are golden brown and the centers look slightly underbaked. They will continue to set as they cool. Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely. The melted peanut butter inside will be very hot, so allow them to cool sufficiently befogin extractindulging!

A: Absolutely! While the classic Peanut Butter M&M Cookies use the standard peanut butter M&Ms, feel free to experiment with other varieties. Peanut M&Ms, caramel M&Ms, or even seasonal colored M&Ms can add a fun twist to your cookies. Just be aware that different M&M types might have slightly different melting properties, which could affect the overall look of the cookies once baked.
