Ingredients & Why They Work

Each ingredient in this Crumbl Monster Cookie Recipe plays its part in creating a cookie that’s colorful, rich, and irresistibly chewy. I always recommend using good-quality chocolate chips and fresh M&M’s to make sure every bite has that perfect pop of flavor and color.

• Butter: Using softened butter (salted or unsalted) ensures a tender crumb and rich flavor; I sometimes use salted for a little extra depth.
• Brown Sugar: Packed brown sugar adds moisture and that subtle caramel flavor which really helps with chewiness.
• Granulated Sugar: This helps the edges crisp up slightly, balancing the soft center perfectly.
• Egg: The egg binds everything together and adds richness.
• Vanilla Extract: Vanilla amps up the sweetness and gives the cookies a warm, inviting aroma.
• All-Purpose Flour: The base of the dough, providing structure without making the cookies tough.
• Baking Soda: Gives a slight lift and ensures a good rise without spreading too much.
• Salt: Enhances all the sweet flavors and balances the sweetness.
• M&M’s: Colorful and crunchy, they bring fun and texture – fresh ones avoid dull colors and cracking.
• Peanut Butter Chips: These add a creamy, nutty sweetness that’s part of what makes these monster cookies unique and addicting.
• Semi-Sweet Chocolate Chips: For that deep, melty chocolate goodness throughout.

Tweak to Your Taste

I love how versatile this Crumbl Monster Cookie Recipe is—once you’ve nailed the basic dough, feel free to get creative! I often swap out chocolate chips for white chocolate on occasion, or toss in chopped nuts for an extra crunch.

• Gluten-Free Variation: I’ve tried using a gluten-free flour blend with good success—just watch the texture as some blends absorb more moisture.
• Nut-Free Option: Skip the peanut butter chips and add extra chocolate or M&M’s if you’re making these for kids with nut allergies.
• Extra Chewy: Use a little bit more brown sugar than granulated for that ultra chewy texture I personally adore.
• Seasonal Twist: Mix holiday-themed M&M’s or add mini peppermint chips around Christmas for festive fun.

Step-by-Step: How I Make Crumbl Monster Cookie Recipe

Step 1: Preheat & Prep Your Workspace

This is key to setting yourself up for success! I always preheat my oven to 325°F and line a baking sheet with parchment paper so the cookies don’t stick and clean-up is a breeze. Having everything ready before mixing helps the process go smoothly without distractions.

Step 2: Cream the Butters and Sugars Until Fluffy

Start by creaming the cold butter, granulated sugar, and brown sugar together. I use a stand mixer, but a hand mixer works great too. The goal here is light, fluffy, and creamy—a few extra minutes really helps the texture of your cookies, making them softer and chewier.

Step 3: Add Egg and Vanilla, Then Mix in Dry Ingredients

Next, beat in one egg and two teaspoons of vanilla extract until fully combined. Then, sift together the flour, baking soda, and salt before adding it to the wet mix. Mix just until you don’t see any flour streaks—overmixing can make cookies tough, so keep it light!

Step 4: Fold in the Magic – M&M’s, Peanut Butter Chips, and Chocolate Chips

Gently fold the candy and chip trio into the dough. I like to reserve a few M&M’s and chips to sprinkle on top right after baking for a pretty, colorful look and extra melty goodness.

Step 5: Scoop, Flatten, and Bake

Using a large cookie scoop, portion out 8 dough balls and place them on the lined baking sheet. Press them gently down to about 1 inch thick so they spread evenly and bake up perfectly. Pop them into your 325°F oven for 12-13 minutes—keep an eye for golden edges but soft centers.

Step 6: Top and Cool to Set

Right after pulling the cookies from the oven, quickly sprinkle a few extra chocolate chips, peanut butter chips, and M&M’s on top. The residual heat will soften them just a bit. Let your cookies rest on the baking sheet for 20 minutes to cool completely before digging in — this step helps them set and keeps them from falling apart.

How to Serve Crumbl Monster Cookie Recipe

Garnishes

I love adding a few extra M&M’s and peanut butter chips right on top after baking—not only does it look fun and colorful, but it also adds a melty little burst of sweetness immediately upon first bite. Sometimes, a light sprinkle of flaky sea salt works wonders to balance the sweetness, especially if you’re a fan of that sweet-and-salty combo.

Side Dishes

These monster cookies go beautifully with a tall glass of cold milk or creamy vanilla ice cream for dessert. I’ve also enjoyed them with coffee or even hot chocolate if I’m craving something cozy on cooler days—perfect as an afternoon pick-me-up!

Creative Ways to Present

For birthday parties or special occasions, I’ve arranged these cookies on a platter with colorful sprinkles and edible glitter to give them a fun, festive vibe. Another favorite trick is stacking them into cute mini cookie sandwiches with peanut butter or chocolate frosting—okay, a little indulgent, but absolutely irresistible!

Make Ahead and Storage

Storing Leftovers

I usually keep leftover monster cookies in an airtight container at room temperature—it keeps them nice and soft for up to 4 days. My personal preference is to store them in the fridge for up to a week, especially in warm weather, then zap them in the microwave for 10-15 seconds before eating to bring back that fresh-out-of-the-oven softness.

Freezing

One of my favorite tricks is freezing these cookie dough balls before baking. Just scoop and arrange them on a tray, freeze until firm, then transfer to a freezer bag. When you want fresh cookies, bake them straight from the freezer—just add a minute or two to the baking time. This way, you have fresh monster cookies anytime the craving hits!

Reheating

Leftover cookies reheat beautifully in the microwave—wrap a paper towel around the cookie to keep moisture in and microwave for 10-15 seconds. You could also gently warm them in a low-temperature oven for 5 minutes. Either way, they come out tasting almost like they just came out of the oven, soft and gooey.
