Ingredients:
- ½ cup unsalted butter, for browning
- ½ cup + 2 tablespoons packed brown sugar
- 2 tablespoons granulated sugar
- 1 large egg, at room temperature
- 1 teaspoon vanilla extract
- 1⅓ cups all-purpose flour, spooned and leveled
- ½ teaspoon baking soda
- ¼ teaspoon 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 (this is approximately 1 tablespoon per cookie, for stuffing)
- Extra milk chocolate chips for garnish
- Extra peanut butter M&Ms for garnish
- Pretzels for garnish (optional)
Preparing the Dough
Step 1: Browning the Butter
The first crucial step for achieving an exceptionally rich and nutty flavor in these Peanut Butter M&M Cookies is to brown the butter. In a medium saucepan, melt the ½ cup of unsalted butter over medium heat. Continue to cook, swirling the pan occasionally, as the butter foams and then subsides. You’ll notice small brown bits forming at the bottom of the pan, and the aroma will become wonderfully nutty. This process takes about 5-8 minutes. Be attentive, as it can go from perfectly browned to burnt very quickly. Once you see these deep golden-brown specks and smell that distinct nutty fragrance, immediately remove the pan from the heat and pour the browned butter into a heat-safe bowl to stop the cooking. Let it cool slightly while you proceed with the next step.
Step 2: Creaming the Sugars and Butter
In a large mixing bowl, combine the slightly cooled browned butter with the ½ cup + 2 tablespoons of packed brown sugar and the 2 tablespoons of granulated sugar. Using an electric mixer (or a whisk and some elbow grease), beat these ingredients together until they are light and fluffy. This creaming process is essential for incorporating air into the dough, which will contribute to the cookies’ tender texture. Scrape down the sides of the bowl periodically to ensure everything is well combined. The mixture should appear pnon-alcoholic ale and airy.
Step 3: Adding Wet Ingredients
Next, add the room-temperature large egg to the creamed sugar mixture. Beating in a room-temperature egg helps it emulsify better, leading to a smoother, more uniform dough. Mix on medium speed until the egg is fully incorporated. You don’t want to see any streaks of egg yolk. Then, stir in the 1 teaspoon of vanilla extract. The vanilla adds a lovely depth of flavor that complements both the peanut butter and chocolate notes beautifully.
Step 4: Combining Dry Ingredients and Incorporating into Wet
In a separate medium bowl, whisk together the 1⅓ cups of all-purpose flour, ½ teaspoon of baking soda, and ¼ teaspoon of salt. Whisking the dry ingredients before adding them to the wet helps to distribute the leavening agents and salt evenly, preventing pockets of bitterness or uneven rising. Gradually add the dry ingredients to the wet ingredients in the large mixing bowl. Mix on low speed, or by hand with a spatula, until just combined. It’s important not to overmix at this stage; overmixing can develop the gluten in the flour too much, resulting in tough cookies. Stop mixing as soon as you no longer see streaks of dry flour.
Step 5: Folding in the Mix-ins
Now for the stars of the show! Gently fold in the ½ cup of milk chocolate chips and the ½ cup of peanut butter M&Ms into the cookie dough. Use a rubber spatula or a wooden spoon for this. Fold until they are evenly distributed throughout the dough. Again, be careful not to overmix. The goal is to get a cohesive dough with pockets of delicious chocolate and peanut butter candies.
Forming and Stuffing the Cookies
Step 6: Shaping the Cookie Bases
Line baking sheets with parchment paper or silicone baking mats. This prevents the cookies from sticking and makes for easier cleanup. Scoop approximately 1.5 to 2 tablespoons of dough for each cookie and roll it into a ball. You should get about 10-12 cookies depending on size. Place the dough balls onto the prepared baking sheets, leaving about 2 inches of space between each one to allow for spreading.
Step 7: The Peanut Butter Core
This is where the magic happens for that irresistible peanut butter center. Take one cookie dough ball and gently flatten it in your palm. Place approximately 1 tablespoon of creamy peanut butter in the center. Now, take another ball of cookie dough, flatten it slightly, and place it on top of the peanut butter, essentially sandwiching it. Carefully pinch the edges of the two dough halves together to completely enclose the peanut butter. Gently re-roll the combined dough into a smooth ball. This technique ensures that each cookie has a delightful molten peanut butter center when baked.
Step 8: Preparing for Baking and Garnishing
Once all your cookies have been formed and stuffed, you can add your garnishes for an extra touch of appeal and flavor. Press a few extra milk chocolate chips and peanut butter M&Ms onto the top of each cookie dough ball. If you’re using pretzels, you can gently press in a piece or two as well. These garnishes not only make the cookies look beautiful but also provide delightful little flavor and texture bursts with every bite.
Baking and Cooling
Step 9: Baking to Perfection
Preheat your oven to 350°F (175°C). Bake the cookies for 10-12 minutes, or until the edges are golden brown and the centers look slightly underbaked. The cookies will continue to set as they cool. For perfectly chewy cookies, aim for this slightly underbaked look. If you prefer a crispier cookie, you can bake them for a minute or two longer.
Step 10: Cooling for Optimal Texture
Remove the baking sheets from the oven and let the cookies cool on the baking sheets for about 5 minutes. This is important because the cookies are very delicate when they first come out of the oven and can fall apart if moved too soon. After they have set slightly on the baking sheets, carefully transfer them to a wire rack to cool completely. This allows air to circulate around the cookies, ensuring they cool evenly and develop the perfect chewy texture. Enjoy your homemade Peanut Butter M&M Cookies!

Frequently Asked Questions about Peanut Butter M&M Cookies:
Q1: My cookies spread too much. What did I do wrong?
This is a common issue! Over-creaming the butter and sugar can incorporate too much air, leading to excessive spread. Another culprit is using softened butter that’s too warm; it should be at room temperature but not melty. Ensure your oven temperature is accurate as well – an oven that’s too cool can also cause cookies to spread more than desired.
Q2: Can I make the dough ahead of time?
Absolutely! Cookie dough for Peanut Butter M&M Cookies can be refrigerated for up to 3 days. Simply cover the bowl tightly with plastic wrap or roll the dough into balls, place them on a parchment-lined baking sheet, and refrigerate. You can bake them directly from the fridge, though you might need to add a minute or two to the baking time. Freezing the dough balls is also an excellent option for longer storage.
