Ingredients & Why They Work
This Christmas Monster Cookies with M&Ms Recipe uses classic pantry staples that come together perfectly. The oats add chewiness and a hint of wholesome texture, while the peanut butter brings richness and that cozy, salty-sweet flavor balance. And of course, the star of the show — the M&Ms — add that pop of color and sweetness with every bite.
- Unsalted Butter: Softened butter helps create that creamy, tender base, so don’t substitute melted butter here unless you want a totally different texture.
- Brown Sugar: Adds moisture and a deep molasses note that pairs beautifully with peanut butter.
- Sugar: Lifts the flavor and helps create those nicely browned edges.
- Creamy Peanut Butter: Skippy’s or Jif work great — the smooth texture helps everything bind and adds signature flavor.
- Egg: Acts as the glue to hold these monster cookies together.
- Vanilla Extract: A must-have to round out the flavors with warmth and depth.
- Rolled Oats: Provides chew and a subtle nuttiness; can swap in quick oats for a softer texture.
- Flour: The backbone that structures the cookie.
- Baking Soda: Gives a gentle lift for just the right fluffiness.
- Salt: Balances the sweetness and enhances flavor.
- Holiday M&Ms: Red and green make these cookies seasonally festive and bring a delightful crunch.
- Chocolate Chips: Semi-sweet or milk — plenty of gooey chocolate in every bite.
Make It Your Way
I love to play around with the mix-ins here — sometimes swapping the chocolate chips for white chocolate chunks or adding a handful of chopped nuts for a bit more crunch. You can easily make these your own festive masterpieces, and I encourage you to experiment depending on what you have on hand.
- Variation: One year, I swapped the peanut butter for almond butter, and it added such a lovely, slightly different nutty twist that everyone loved.
- Dietary Modification: Use gluten-free oats and flour blend to make this recipe gluten-free without compromising texture.
- Seasonal Swap: Try colored chocolate candies that match other holidays for a fun twist year-round.
Step-by-Step: How I Make Christmas Monster Cookies with M&Ms Recipe
Step 1: Cream Together the Butter and Sugars Until Fluffy
Start by beating the softened butter, brown sugar, and sugar together in a large mixing bowl. I usually use my stand mixer here, but a hand mixer works fine too. Beat for about 4 minutes until the mixture looks light, fluffy, and a tad lighter in color. This step is key — it’s what gives your cookies that tender, melt-in-your-mouth texture.
Step 2: Add Peanut Butter, Egg, and Vanilla
Next, stir in the creamy peanut butter, crack in your egg, and pour in the vanilla extract. Beat everything together for another minute until it’s well combined. If your peanut butter is a little stiff, warming it a bit in the microwave helps it blend easier.
Step 3: Fold in the Dry Ingredients and Mix-Ins
Now it’s time to add your oats, flour, baking soda, and salt. Stir gently—just enough to combine. Avoid overmixing here, or your cookies can turn tough. Lastly, fold in the chocolate chips and most of your holiday M&Ms, saving a little for pressing on top once the cookies are baked.
Step 4: Chill the Dough
Tightly wrap your dough and pop it into the fridge for about 30 minutes. This chilling step is one I never skip — it makes it easier to scoop and helps the cookies keep their shape in the oven.
Step 5: Bake and Add the Finishing Touch
Preheat your oven to 365°F, then scoop your dough onto a light-colored baking sheet, spacing each cookie at least 2 inches apart. Bake for 9 to 10 minutes — watch for the edges to be set but the centers still soft. Right after pulling them out, gently press the remaining M&Ms into the tops. Let them cool for at least 5–10 minutes on the sheet before moving to a wire rack or plate.
Top Tip
Over the years, I’ve learned a few tricks that make this Christmas Monster Cookies with M&Ms Recipe foolproof and extra delicious. Trust me, these will save you some trial and error in your kitchen!
- Softened Butter, Not Melted: Using properly softened butter keeps your cookies fluffy — melted butter makes them spread too thin.
- Don’t Overmix: Once you add the flour, mix just until combined to keep your cookies tender, not tough.
- Chill the Dough: This little step helps maintain cookie shape and develop flavor — I even sometimes chill it overnight for extra depth.
- Use a Light-Colored Baking Sheet: Dark pans can cause over-browning; light pans bake more evenly for perfect color.
How to Serve Christmas Monster Cookies with M&Ms Recipe
Garnishes
I keep it classic and simple with these cookies — just pressing extra M&Ms on top as they cool adds the perfect pop of color and crunch. Sometimes, I sprinkle a pinch of flaky sea salt on top right after baking to balance out the sweetness and add a little gourmet touch.
Side Dishes
These cookies pair wonderfully with a glass of cold milk or your favorite holiday hot cocoa. For parties, I like setting them out alongside other festive treats like gingerbread men, peppermint bark, and spiced nuts to create a cozy cookie buffet.
Creative Ways to Present
One holiday season, I stacked these Christmas Monster Cookies with M&Ms Recipe into a playful “cookie tree,” using a little frosting as glue between layers. It was a hit! You can also wrap them in colorful cellophane tied with a ribbon for sweet neighbor gifts — quick, pretty, and delicious.
Make Ahead and Storage
Storing Leftovers
I store leftover cookies in an airtight container at room temperature. They usually last about 3 days before they start losing that fresh-baked soft chewiness. For best texture, I sometimes separate layers with parchment paper to prevent sticking.
Freezing
These cookies freeze beautifully! I like to freeze the baked cookies arranged neatly in a zipper bag or airtight container for up to two months. When I’m ready to enjoy them, they thaw quickly at room temperature and taste nearly as good as fresh.
Reheating
For that just-baked warmth, I pop individual cookies in the microwave for about 10-15 seconds or heat them briefly in a 300°F oven for 5 minutes. It revives the melty chocolate and soft texture without drying them out.
Frequently Asked Questions:
You can, but creamy peanut butter is what I recommend because it blends smoothly into the dough, ensuring consistent texture. Crunchy peanut butter will add extra bits of peanut, which some people enjoy, but it may slightly change the chewiness of the cookies.
While oats add a nice chewy texture and a nutty flavor, you can omit them if needed. To compensate, try adding an extra ¼ cup of flour to keep the dough balanced. The cookies will be less chewy but still delicious.
This recipe makes about 16 monster-sized cookies, perfect for sharing during holiday parties or gift-giving. If you want smaller cookies, you can scoop smaller portions and increase the baking time slightly.
Absolutely! You can swap the red and green holiday M&Ms for regular M&Ms, peanut M&Ms, or even mini chocolate chips. Just pick whatever candy you like or have on hand for a fun twist on the classic Christmas Monster Cookies recipe.
