What Ingredients You Will Need
This peanut butter M&M cookies recipe uses straightforward, crowd-pleasing ingredients that create big flavor without any fuss. Most are pantry staples, and a few simple swaps let you tweak them to your liking. Here’s what you’ll need:
- For the Cookie Dough:
- Unsalted butter, softened (1/2 cup / 113g) – Adds richness and helps the cookies stay soft. If you only have salted butter, just reduce the added salt slightly.
- Creamy peanut butter (1/2 cup / 130g) – Classic peanut flavor! I recommend a no-stir brand like Jif or Skippy for best texture. Natural peanut butter works, but cookies will be a little more rustic.
- Granulated sugar (1/2 cup / 100g) – For that classic cookie sweetness and a little crispness at the edges.
- Brown sugar, packed (1/2 cup / 110g) – Keeps the cookies chewy and adds a hint of caramel flavor. Light or dark both work; I usually grab light brown sugar.
- Large egg (1, room temperature) – Helps bind everything and adds richness.
- Vanilla extract (1 teaspoon / 5ml) – Rounds out all the flavors. Use pure vanilla if you can!
- All-purpose flour (1 1/4 cups / 160g) – Gives structure. If you want a gluten-free option, swap with a 1:1 gluten-free baking blend (I’ve tried King Arthur GF with great results).
- Baking soda (1/2 teaspoon / 2g) – For lift and a little spread.
- Salt (1/4 teaspoon / 1g) – Balances the sweetness and makes the peanut butter pop.
- For the Mix-Ins:
- M&M candies (3/4 cup / 130g, plus extra for topping) – Regular, mini, or seasonal colors all work. Minis distribute more evenly, but I love the classic crunch of the regular ones.
- Optional: Semi-sweet chocolate chips (1/4 cup / 45g) – For extra chocolatey bites. If you’re feeling wild, a handful of Reese’s Pieces is fun too.
Ingredient Tips:
- For a nut-free version, use sunflower seed butter and nut-free chocolate candies.
- If you prefer crunchy peanut butter, go for it—the cookies will have a bit more texture. I’ve made them both ways and never had complaints.
- Want a more pronounced peanut flavor? Toast the flour in a dry skillet for a few minutes before adding. It’s a subtle step, but it does add depth.
- For holiday bakes, swap in themed M&Ms (think red and green for Christmas, pastels for Easter) for a festive touch.
Equipment Needed
- Mixing bowls (medium and large): You’ll need one for wet and one for dry ingredients. I use my trusty glass bowls, but plastic works just fine.
- Electric mixer or sturdy whisk: A hand mixer makes creaming the butter and sugars super easy, but a strong arm and a good whisk will do the trick in a pinch.
- Rubber spatula: For scraping down the bowl and gently folding in M&Ms (so they don’t break apart).
- Measuring cups and spoons: Accurate measurements = consistent cookies. I use a digital scale for flour when I want perfect results.
- Baking sheet (cookie sheet): Lined with parchment paper or a silicone baking mat to keep cookies from sticking and for easy cleanup.
- Cookie scoop or tablespoon: For evenly sized cookies. I like a medium scoop for classic, bakery-sized cookies, but a regular spoon works in a pinch.
- Wire cooling rack: For cooling cookies evenly and keeping the bottoms from getting soggy.
Alternatives & Tips: No cookie scoop? Two spoons work fine—just try to keep the dough balls about the same size. If you don’t have a silicone baking mat, parchment paper is your best friend (and makes cleanup a breeze). I once tried these cookies on an ungreased baking sheet—never again. They stuck, and my husband had to “taste test” the broken ones. Lesson learned!
Preparation Method
-
Preheat and Prep:
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat. This keeps your cookies from sticking and helps them bake evenly. -
Cream the Butter, Peanut Butter, and Sugars:
In a large mixing bowl, add 1/2 cup (113g) unsalted butter (softened), 1/2 cup (130g) creamy peanut butter, 1/2 cup (100g) granulated sugar, and 1/2 cup (110g) packed brown sugar. Beat with an electric mixer (or sturdy whisk) until the mixture is light, fluffy, and slightly lighter in color—about 2-3 minutes. If you notice the mixture isn’t smooth, scrape down the sides and keep mixing. -
Add Egg and Vanilla:
Crack in 1 large egg (room temperature) and pour in 1 teaspoon (5ml) vanilla extract. Beat again until just combined—don’t overdo it, or the dough can get tough. -
Combine Dry Ingredients:
In a separate medium bowl, whisk together 1 1/4 cups (160g) all-purpose flour, 1/2 teaspoon (2g) baking soda, and 1/4 teaspoon (1g) salt. This helps distribute the leavening evenly. -
Mix Wet and Dry Ingredients:
Gradually add the dry ingredients to the wet mixture. I do this in two parts, mixing on low until just combined. The dough should be soft but not sticky—if it’s too sticky, add 1-2 tablespoons (8-15g) more flour. -
Fold in M&Ms (and Chips, if using):
Gently fold in 3/4 cup (130g) M&M candies and 1/4 cup (45g) chocolate chips, if using. Try not to overmix—just until everything’s evenly distributed. If you want picture-perfect cookies, reserve a handful of M&Ms for pressing onto the tops before baking. -
Scoop and Chill (Optional):
Scoop dough into balls about 1.5 tablespoons each (35-40g), spacing them 2 inches apart on your lined baking sheet. For super thick cookies, chill the scooped dough in the fridge for 20-30 minutes. Totally optional, but really helpful if your kitchen is warm! -
Bake:
Bake in preheated oven for 9-11 minutes, until edges are set but centers look slightly underbaked. They’ll firm up as they cool! If you want extra M&Ms on top, press them gently into the cookies right after baking. -
Cool and Enjoy:
Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. Or, you know, eat one warm—no one’s judging.
Preparation Notes: If your cookies spread too much, your butter may have been too soft or the dough needed a little more chilling. If they’re too thick, try pressing the dough balls down slightly before baking. The dough can be made ahead and refrigerated for up to 2 days (just let it soften slightly before scooping).
Cooking Tips & Techniques
- Room-Temperature Ingredients: Don’t skip this! Using a room-temperature egg and softened butter helps create a super smooth, cohesive dough. Cold ingredients can lead to uneven mixing and tough cookies.
- The Right Peanut Butter: I’ve learned the hard way that natural peanut butters can make the dough too oily and crumbly. Stick with creamy, no-stir peanut butter for the best, soft texture.
- Chilling the Dough: If your kitchen is warm or your butter was very soft, chill the dough for at least 20 minutes before baking. This helps prevent the cookies from overspreading and keeps them thick and chewy.
- For Picture-Perfect Cookies: Always press a few extra M&Ms into the tops of the dough balls right before baking. It makes for a bakery-style look that photographs beautifully (hello, Pinterest!).
- Even Baking: Bake one sheet at a time in the center of the oven for the most consistent results. If baking multiple sheets, rotate halfway through to avoid uneven browning.
- Don’t Overbake: The cookies should look slightly underdone in the center when you take them out—trust me, they’ll finish setting as they cool. Overbaked cookies will be dry and crumbly.
- Personal Fails: Once, I forgot to measure my flour and just “eyeballed” it. The cookies turned into flat, crunchy pancakes—not ideal. Measure carefully for perfect results every time!
- Multitasking Tip: While the first tray bakes, scoop the rest of your dough and pop it in the fridge. This way, you’ll always have chilled dough ready to go for round two.
Variations & Adaptations
- Gluten-Free: Swap the all-purpose flour for a 1:1 gluten-free baking blend. I’ve had great luck with King Arthur and Bob’s Red Mill. The cookies come out just as soft and chewy—no one will notice the difference.
- Vegan: Use a dairy-free, plant-based butter and a flax egg (1 tablespoon ground flax + 2.5 tablespoons water, mixed and rested for 5 minutes). Choose vegan chocolate candies or chocolate chips. The flavor is a bit different, but still super satisfying.
- Flavor Boosts: Try swapping the M&Ms for peanut butter chips, toffee bits, or chopped mini peanut butter cups for a fun twist. I once made these with caramel M&Ms and my kids went absolutely wild for them.
- Allergen-Friendly: For nut allergies, substitute sunflower seed butter and use nut-free chocolate candies (there are a few brands out there now!). The cookies get a slight sunflower flavor but still hit the spot for anyone missing peanut butter cookies.
- Seasonal Swaps: For the holidays, grab themed M&Ms—think red and green for Christmas, pastel for Easter, or orange and brown for Halloween. I love making a big batch and packing them in festive tins for gifts.
My personal go-to? A half-and-half mix of regular and peanut M&Ms. It’s a little chunkier, but the mix of chocolate and peanut crunches is just… wow. If you like your cookies extra nutty, give it a try!
Serving & Storage Suggestions
These peanut butter M&M cookies are best enjoyed slightly warm, with the chocolate centers just a little gooey and the candy shells still crunchy. I like to pile them on a big plate and serve with cold milk or, for grown-ups, a mug of coffee. For parties, stack them in a glass jar—those bright M&Ms just look so inviting.
- Serving Temperature: Warm is always a win, but room temperature works great too. If you want that just-baked vibe, pop a cookie in the microwave for 8-10 seconds.
- Pairings: Serve with vanilla ice cream for an easy dessert, or alongside a bowl of fresh fruit for a sweet-and-salty snack spread.
- Storing: Keep cookies in an airtight container at room temperature for up to 5 days. They stay soft and chewy—if they start to dry out, toss a slice of bread into the container to keep them fresher longer.
- Freezing: Freeze baked cookies in a zip-top bag for up to 3 months. Or, freeze unbaked dough balls and bake straight from the freezer—just add 1-2 extra minutes to the bake time.
- Flavor Development: The peanut butter flavor actually deepens after a day or two, so if you can resist, save a few cookies to enjoy later. (Easier said than done!)
