Every holiday season, I end up making at least one batch of cookies that disappears almost as fast as I can cool them, and these Christmas M&M Peanut Butter Cookies are always at the top of that list. They bake up soft in the center, lightly golden around the edges, and packed with melty chocolate in every bite. The peanut butter adds just enough richness to make them extra cozy without overpowering the festive candy crunch.

What I love most is how cheerful they look on a cookie tray. The red and green candies make them feel instantly holiday-ready, while the chocolate chips tucked into the dough give them that bakery-style finish I always reach for when I want something simple but still a little special. These are the kind of cookies I bake for cookie exchanges, weekend baking with the kids, and those evenings when I just want the kitchen to smell like Christmas.

Why You’ll Love These Christmas M&M Peanut Butter Cookies

I love this cookie recipe because it gives me the best of both worlds: classic peanut butter cookie flavor and soft chocolate chip cookie texture. The centers stay tender, the edges hold their shape beautifully, and the holiday M&M candies make every batch feel bright and festive.

These cookies are also easy to make with pantry staples, which is a huge win during busy baking season. I can mix the dough without anything fancy, chill it if I have time, and bake a batch that looks beautiful enough for gifting but easy enough for a casual weeknight treat.

What Kind of Peanut Butter Should I Use for Christmas M&M Peanut Butter Cookies?

I always reach for a regular creamy peanut butter for this recipe because it gives the dough a smooth texture and reliable structure. Natural peanut butter can sometimes separate and make cookie dough a little unpredictable, especially if the oil is not fully blended in.

If I want the cookies to stay thick, soft, and evenly baked, creamy shelf-stable peanut butter is my first choice. Crunchy peanut butter can work too if I want a little extra texture, but I still like to keep the mix-ins balanced so the M&Ms and chocolate chips remain the stars.

Ingredients for the Christmas M&M Peanut Butter Cookies

Each ingredient in these cookies plays a role in building the soft, chewy texture and rich holiday flavor. I like knowing exactly why everything goes into the bowl, because it makes the whole recipe feel easier and more dependable.

Unsalted Butter

Butter gives these cookies richness and helps create those lightly crisp edges that make the soft centers stand out.

Creamy Peanut Butter

Peanut butter brings the signature nutty flavor and adds moisture, which helps the cookies stay tender.

Brown Sugar

Brown sugar adds softness, chewiness, and a deeper caramel-like sweetness that pairs beautifully with peanut butter.

Granulated Sugar

Granulated sugar helps sweeten the dough and supports a lightly crisp exterior.

Egg

The egg binds the dough together and helps the cookies bake up with structure and softness.

Vanilla Extract

Vanilla rounds out the peanut butter and chocolate flavors and gives the dough a warm bakery-style aroma.

All-Purpose Flour

Flour gives the cookies their body and keeps the dough sturdy enough to hold the candies and chocolate chips.

Baking Soda

Baking soda helps the cookies rise just enough while keeping the texture soft and chewy.

Salt

A little salt balances the sweetness and makes the peanut butter and chocolate taste even better.

Semi-Sweet Chocolate Chips

Chocolate chips melt into the dough and add rich little pockets of chocolate throughout each cookie.

Red and Green Christmas M&Ms

The Christmas M&Ms bring color, crunch, and that festive look that makes these cookies perfect for holiday platters.

How To Make the Christmas M&M Peanut Butter Cookies

I like to make these cookies in a few simple steps so the dough stays easy to handle and the cookies bake evenly. Once the dough comes together, the hardest part is waiting for them to cool enough to eat.

Step 1: Cream the Butter, Peanut Butter, and Sugars

I start by beating the butter, peanut butter, brown sugar, and granulated sugar together until the mixture looks light and creamy. This step helps build a smooth base and makes the finished cookies softer.

Step 2: Add the Egg and Vanilla

Next, I mix in the egg and vanilla extract until everything is fully combined. At this point, the dough starts to smell sweet, rich, and incredibly good.

Step 3: Mix in the Dry Ingredients

I add the flour, baking soda, and salt, then mix just until no dry streaks remain. I try not to overmix here because that can make the cookies a little too dense.

Step 4: Fold in the Chocolate Chips and M&Ms

Once the dough is ready, I gently fold in the chocolate chips and most of the Christmas M&Ms. I like to save a few candies for pressing on top before baking so the cookies come out extra pretty.

Step 5: Scoop and Shape the Dough

I scoop the dough into even portions and place them on a parchment-lined baking sheet. If I want thicker cookies, I chill the dough for about 20 to 30 minutes before baking.

Step 6: Bake Until Soft in the Center

I bake the cookies just until the edges are set and the centers still look slightly soft. They continue to finish baking on the pan as they cool, which gives them that perfect chewy texture.

Step 7: Cool and Enjoy

I let the cookies rest on the baking sheet for a few minutes before moving them to a wire rack. This helps them set up without breaking apart, and it gives the chocolate time to become perfectly melty.

Serving and Storing Christmas M&M Peanut Butter Cookies

These cookies are one of my favorite holiday desserts to set out on a platter with hot cocoa or coffee. They are rich enough to feel special but easy enough to make for a casual weekend bake. This recipe feeds about 24 people if I serve one cookie per person, or around 12 people if everyone grabs two.

To store them, I keep the cookies in an airtight container at room temperature for up to 5 days. If I want to make them ahead, I freeze the baked cookies or the unbaked dough balls for longer storage. A quick few seconds in the microwave brings back that soft, fresh-baked texture.

What to Serve With Christmas M&M Peanut Butter Cookies?

These cookies are easy to pair with all kinds of cozy holiday favorites. I usually serve them with a mix of drinks and simple sweet additions so the cookie tray feels extra inviting.

1. Hot Chocolate

A mug of rich hot chocolate makes these cookies feel even more festive and brings out the chocolate in every bite.

2. Cold Milk

This classic pairing keeps the sweetness balanced and makes the peanut butter flavor shine.

3. Vanilla Ice Cream

A scoop of vanilla ice cream turns a warm cookie into an easy holiday dessert.

4. Coffee or Peppermint Mocha

Coffee adds a slightly bitter contrast that works beautifully with the sweet candy-coated chocolate.

Frequently Asked Questions

Can I make Christmas M&M Peanut Butter Cookies ahead of time?

Yes, and I do it often during the holiday season. I either make the dough a day ahead and keep it covered in the refrigerator, or I scoop the dough into balls and freeze them. That way I can bake a fresh batch whenever I need cookies for guests, gifting, or a last-minute dessert tray.

Why did my cookies spread too much?

If the cookies spread more than expected, the butter may have been too soft or the dough may have needed a quick chill before baking. I like to chill the dough when my kitchen is warm or when I want thicker cookies. Measuring the flour carefully also helps keep the dough from becoming too loose.

Can I use only M&Ms and skip the chocolate chips?

Absolutely. I like using both because the mix gives me extra chocolate and a prettier texture inside the cookies, but using only Christmas M&Ms still works well. The cookies will be a little sweeter and slightly crunchier in places, but still delicious.

Can I freeze these cookies after baking?

Yes, these cookies freeze really well. I let them cool completely, then place them in a freezer-safe container with layers separated by parchment paper. When I am ready to serve them, I thaw them at room temperature or warm one briefly for that soft, fresh-baked feel.

How do I keep the M&Ms from cracking too much?

A little cracking is completely normal, especially in the oven, but I get the best results when I fold most of the candies into the dough gently and press a few extra on top right before baking. That keeps the cookies colorful and festive without crushing all of the candy shells.

In the mood for more cozy kitchen inspiration? I love pairing holiday baking with comforting favorites like Melted Snowman Peanut Butter Cookies, buttery Chocolate Chip Snowball Cookies, crowd-pleasing Peanut Butter Icing, and a mug of homemade Apple Chai Latte.
