Essential Ingredients for Perfect Peanut Butter M&M Cookies
Crafting these delectable cookies starts with selecting the right ingredients. Here’s a detailed breakdown of what you’ll need and why each component is crucial for achieving that signature soft, chewy, and intensely flavorful result:
- Peanut Butter: For achieving the best possible texture and flavor consistency in your cookies, we highly recommend using a regular creamy peanut butter. Brands like Jif or any good quality store-brand alternative work wonderfully. Based on feedback from numerous bakers, natural-style peanut butters (which often separate and have a different oil content) tend to yield cookies that don’t spread or hold their shape as well, leading to a less satisfying result.
- Butter: We prefer using salted butter as it naturally enhances the overall flavor of the cookies, balancing the sweetness. However, unsalted butter can be used if you prefer to control the salt content precisely. Absolutely avoid margarine, as its different fat composition will alter the cookie’s texture. Ensure your butter is softened to room temperature – it should be pliable but not melted – before incorporating it into the dough for optimal creaming.
- Granulated Sugar: A fundamental component of any cookie, granulated sugar contributes to the sweetness and also helps achieve that desirable crispness on the edges of the cookies. It’s essential for the overall structure and taste profile.
- Brown Sugar: The inclusion of brown sugar is key for several reasons: it adds a deeper, more complex molasses flavor, and its inherent moisture contributes significantly to the cookies’ characteristic soft and chewy texture. Always make sure your brown sugar is fresh and soft, not dried out or stale, to ensure it properly integrates into the dough and provides its full benefits.
- Egg: Just one large egg plays a vital role in this recipe. It acts as a primary binding agent, helping to hold the cookie dough together. This ensures that your cookies maintain their shape during baking and don’t crumble apart, resulting in a cohesive and satisfying cookie.
- Milk: A small amount of milk is incorporated to provide just the right touch of moisture to the cookie dough. This extra liquid helps create a tender crumb and prevents the cookies from becoming too dry. Any type of milk you have on hand – dairy or non-dairy – will work perfectly in this recipe.
- Vanilla Extract: High-quality vanilla extract is a game-changer, elevating the flavor profile of the cookies by adding warmth and depth. We strongly suggest investing in a good quality vanilla extract or even a Vanilla Bean Paste for a truly superior taste experience.
- All-Purpose Flour: Standard all-purpose flour is typically what we use, providing the necessary structure for the cookies. However, for those looking to experiment, bread flour can add a slightly chewier texture, while pastry flour might result in a more tender cookie.
- Baking Powder: As a crucial leavening agent, baking powder helps the cookies rise and achieve their appealing fluffy yet chewy texture. To ensure maximum effectiveness, always check that your baking powder is fresh and not expired; old baking powder can lead to flat, dense cookies.
- Salt: While only a small amount is needed, salt is incredibly important for balancing the sweetness and enhancing all the other flavors in the cookie. Don’t be tempted to leave it out, as it brings out the best in the peanut butter and sugars.
- Peanut Butter M&M’s: The star of the show! While you could substitute with regular M&M’s or chocolate chips, we enthusiastically recommend sticking with Peanut Butter M&M’s for an unparalleled flavor combination. To ensure an even distribution of flavor and texture throughout each cookie, we love to gently smash them up a little bit. Simply place them in a Ziploc bag and use a meat mallet or rolling pin. Remember not to over-smash – you want noticeable, chunky pieces for maximum impact!

Expert Recipe Tips for Flawless Cookies
While the complete, step-by-step instructions for these incredible cookies are conveniently located on the recipe card below, here are some invaluable tips to help you achieve bakery-perfect results every single time:
- Monitor the Bake Time Closely: The secret to perfectly soft and chewy cookies lies in precise baking. These cookies are at their absolute best when they are just barely baked through. It’s crucial to keep a vigilant eye on the oven, especially during the final minute or two of baking. Look for edges that appear set and lightly golden, but don’t be alarmed if the centers still look slightly soft or underdone – this is precisely what you’re aiming for! They will continue to firm up beautifully as they cool on the baking sheet, ultimately yielding that coveted soft, tender, and perfectly chewy texture. Overbaking is the enemy of chewiness!
- Utilize Parchment Paper or Silicone Mats: For consistent baking and easy cleanup, we highly recommend lining your baking sheets with either parchment paper or reusable silicone baking mats. This simple step is a game-changer as it helps prevent the bottoms of your cookies from over-browning or sticking, particularly if you’re using darker baking sheets that tend to conduct heat more intensely. Furthermore, it ensures your cookies maintain their ideal shape and don’t spread excessively.
- Roughly Crush Peanut Butter M&Ms for Optimal Distribution: While whole M&Ms are fine, gently chopping or crushing the Peanut Butter M&M’s is a clever trick that elevates the cookie experience. This technique guarantees that you get delightful bits of that sweet and crunchy peanut butter candy in every single bite, rather than encountering large, uneven chunks. It not only ensures a more even distribution of flavor and texture throughout the cookie dough but also contributes to a more uniform and appealing cookie structure.
- Scoop Evenly for Uniform Cookies: For a batch of cookies that bake consistently and look professionally made, a small cookie scoop is your best friend. Using a scoop ensures that each ball of dough is roughly the same size, which is critical for even baking. Uniformly sized cookies will cook at the same rate, preventing some from being overdone while others are still raw. Plus, perfectly symmetrical cookies always make for a more polished and impressive presentation, especially when baking for guests or as a thoughtful gift.
- Adorn with Extra M&Ms Before Baking: To achieve that irresistible, bakery-style visual appeal, don’t forget this finishing touch. Before popping your dough balls into the oven, gently press a few extra whole Peanut Butter M&M’s onto the tops of each one. This ensures that every baked cookie boasts a vibrant, colorful, and fun appearance, and guarantees an abundance of that beloved M&M goodness visible right on the surface. It’s a small step that makes a big difference!

Storage Instructions to Keep Cookies Fresh
To ensure your homemade Peanut Butter M&M Cookies remain wonderfully soft and delicious, proper storage is essential. Once completely cooled, store them in an airtight container at room temperature. They will maintain their excellent quality for up to 4-5 days. For extended enjoyment, these cookies freeze beautifully. Simply place them in a freezer-safe bag or container, and they can be stored for up to 3 months. When you’re ready to enjoy them, just thaw at room temperature for a few hours before serving.
If you prefer to bake fresh cookies on demand, you can also freeze the unbaked dough. Shape the dough into individual balls first, then arrange them on a baking sheet and freeze until solid. Once frozen, transfer the dough balls to a freezer-safe bag or container. This convenient method allows you to bake just a few cookies at a time, straight from the freezer, whenever a craving for warm, fresh-baked cookies strikes.

PEANUT BUTTER M&M COOKIES RECIPE

Pin
Rate
Ingredients
- 1 cup peanut butter* (creamy, regular style recommended)
- ½ cup butter softened (salted or unsalted)
- ½ cup granulated sugar
- ½ cup brown sugar
- 1 large egg
- 3 Tbsp milk (any type)
- 1 tsp vanilla extract (good quality)
- 1½ cups all-purpose flour
- ¾ tsp baking powder
- ¼ tsp salt
- 1-2 cups Peanut Butter M&Ms lightly crushed, plus more for topping if desired
Instructions
-
Preheat your oven to 375°F (190°C). Prepare baking sheets by lining them with parchment paper or silicone baking mats.
-
In a large mixing bowl, using a hand mixer or stand mixer, cream together the peanut butter, softened butter, granulated sugar, and brown sugar until the mixture is light, fluffy, and well blended. Beat in the egg, milk, and vanilla extract until fully combined.
-
In a separate medium bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add this dry flour mixture to the wet peanut butter mixture, mixing on low speed until just combined. Be careful not to overmix the dough.
-
Gently stir in the lightly crushed Peanut Butter M&Ms by hand until they are evenly distributed throughout the dough. Scoop tablespoonfuls of dough and roll them into smooth, uniform balls.
-
Place the cookie dough balls about 2 inches apart on your prepared baking sheets. For that classic peanut butter cookie look, gently press each ball once with a fork, creating a crosshatch pattern. You can also press a few extra M&Ms onto the tops of the dough balls for extra visual appeal.
-
Bake for 8-10 minutes. It’s crucial not to overcook these cookies! They are significantly better when they are soft and just barely cooked through. The edges should look set, but the centers may still appear slightly soft – this is the desired doneness.
-
Allow the cookies to cool on the hot cookie sheet for a few minutes after removing them from the oven. This allows them to finish setting without drying out. Then, carefully transfer them to a wire rack to cool completely. Enjoy!

Frequently Asked Questions (FAQs)
Here are answers to some common questions about making these delectable Peanut Butter M&M Cookies:
Can I use other types of M&M’s in this recipe?
Absolutely! While Peanut Butter M&M’s are highly recommended for an extra burst of peanut butter flavor that truly complements the cookie, this recipe is wonderfully versatile. Feel free to experiment with regular chocolate M&M’s, peanut M&M’s, or even pretzel M&M’s for a delightful salty crunch. Each variation will offer a unique and tasty twist on the classic.
Is it possible to prepare the cookie dough in advance?
Yes, you can certainly get a head start on your baking! The prepared cookie dough can be stored in the refrigerator for up to 24 hours before you plan to bake. To ensure the best texture, allow the dough to sit at room temperature for approximately 20 minutes before you begin scooping and shaping the cookies.
Do I have to press the cookies with a fork before baking?
Pressing the cookies with a fork to create the classic crosshatch pattern is entirely optional. It primarily serves two purposes: it gives the cookies that traditional, recognizable peanut butter cookie appearance, and it helps them bake more evenly by slightly flattening the dough balls. If you prefer a more rounded, rustic look or are short on time, you can skip this step without affecting the taste.
