• Unsalted butter (1 cup, room temperature): Provides a tender crumb and helps the cookies spread evenly.
• Light brown sugar (1 ½ cups): Adds moisture and a subtle caramel depth for soft, chewy cookies.
• Granulated sugar (½ cup): Balances sweetness and contributes to crisp edges.
• Creamy peanut butter (1 cup): Brings that rich, nutty flavor that defines these cookies.
• Large eggs (2, room temperature): Bind ingredients together and add a light, fluffy texture.
• Vanilla extract (2 tsp): Enhances the flavor complexity and warmth.
• All-purpose flour (3 cups): The base that holds everything together and creates structure.
• Baking soda (1 tsp): Helps the cookies rise and achieve that perfect soft chewiness.
• Salt (1 tsp): Balances out sweetness and amplifies other flavors.
• Mini M&Ms (16 oz): The colorful chocolate candy bursts that bring excitement and crunch.

How to Make Peanut Butter M&M Cookies

Step 1: Prep Your Oven and Baking Sheets

Start by heating your oven to 350°F (177°C). Line your baking sheets with silicone mats or parchment paper to prevent sticking and help your cookies bake evenly. This little prep step sets the stage for perfect cookies.

Step 2: Cream the Butter and Sugars

Using your electric hand mixer or a stand mixer with a paddle attachment, cream together the unsalted butter, brown sugar, and granulated sugar on medium speed until light and fluffy. This blending creates the ideal texture for a tender cookie crumb.

Step 3: Add the Peanut Butter, Eggs, and Vanilla

Next, mix in the creamy peanut butter, eggs, and vanilla extract until the mixture is smooth and well combined. These additions bring moisture, richness, and a deep, nutty character that you’ll love.

Step 4: Incorporate the Dry Ingredients

Slowly add the flour, baking soda, and salt while mixing on low speed. The dough will begin to come together, thick and soft. Scrape down the bowl to ensure all ingredients are evenly distributed—this step is key for consistent cookies.

Step 5: Roll the Dough in M&Ms and Shape the Cookies

Use a large cookie scoop (about 3 tablespoons) to portion the dough. Roll the dough balls gently on a plate of mini M&Ms, pressing the candies into the dough so they stick well. If your dough gets misshapen, simply smooth it out carefully. Place the balls on your prepared pans, giving plenty of space for spreading.

Step 6: Bake and Cool

Bake for about 12 minutes until the edges are golden and set, but the centers still look slightly underbaked (this keeps them tender and chewy). Let the cookies cool on the pan for 2 minutes, then transfer to a wire rack to cool completely and firm up.

How to Serve Peanut Butter M&M Cookies

Garnishes

If you want to jazz up these cookies a bit more, consider sprinkling a pinch of flaky sea salt right after baking—this little touch enhances the peanut butter flavor and balances the sweetness beautifully.

Side Dishes

These cookies pair wonderfully with a cold glass of milk, a scoop of vanilla ice cream, or a cup of hot coffee or tea. Their sweet, nutty, and colorful nature makes them a perfect dessert or snack companion.

Creative Ways to Present

For parties or gifting, stack these Peanut Butter M&M Cookies with wax paper layers in a festive tin or jar. You can also sandwich them with peanut butter or chocolate frosting for a delightful twist that adds extra indulgence.

Make Ahead and Storage

Storing Leftovers

Keep your leftover cookies fresh by storing them in an airtight container or zip-top bag at room temperature for 2 to 3 days. This helps maintain their soft, chewy texture and delicious flavor.

Freezing

You can freeze both unbaked cookie dough balls and baked cookies. For dough, portion and roll them in M&Ms, store in an airtight container or bag, and freeze for up to 3 months. When ready, thaw for one hour before baking. For baked cookies, store in a freezer-safe container for up to 3 months and allow to thaw at room temperature before enjoying.

Reheating

If you want to freshly warm your Peanut Butter M&M Cookies, pop them in a preheated oven at 300°F for 5 to 7 minutes, or microwave for 10 to 15 seconds. The warmth softens the chocolate and brings out all that peanut buttery goodness.

FAQs

Can I use crunchy peanut butter instead of creamy?

Absolutely! Crunchy peanut butter will add more texture to your cookies, making each bite a little more exciting. Just keep in mind the cookies might be a bit chunkier.

Can I substitute the M&Ms with another candy?

Yes! While classic mini M&Ms bring great color and crunch, feel free to experiment with Reese’s Pieces, chocolate chips, or even chopped nuts to customize your cookies.

How do I prevent my cookies from spreading too much?

Chilling the dough for 30 minutes before baking can help control spreading. Also, be sure not to over-cream the butter and sugars, and use fresh baking soda for proper rise.

Can I make these cookies gluten-free?

To make gluten-free versions, substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. Make sure the blend includes xanthan gum for proper texture.

Will these cookies keep their freshness for a long time?

For best flavor and texture, enjoy within a few days stored at room temperature. Freezing extends their life, but they’re always best fresh or gently reheated.
