Butter: I use softened butter to make sure it creams perfectly with sugars, helping the dough stay tender but hold its shape.
Brown Sugar: Adds moisture and a subtle caramel flavor that deepens the cookie’s deliciousness.
Granulated Sugar: Gives just enough crunch and helps cookies spread just right.
Egg: Binds everything together and keeps the cookies soft and chewy.
Vanilla Extract: Enhances all the flavors—it’s such an easy way to boost cookie flavor beautifully.
All-Purpose Flour: The backbone of your cookie dough; be sure to measure correctly by spooning and leveling the flour to avoid dryness.
Baking Soda: Creates gentle leavening to keep the cookies airy and tender.
Salt: Balances the sweetness and brings out the deeper flavors in the dough and mix-ins.
M&M’s: Classic candy-coated chocolate that creates little pops of color and crunch—don’t skip these!
Peanut Butter Chips: These melt into creamy pockets of peanut butter yum—feel free to swap for more chocolate chips if you’re peanut allergic.
Semi-Sweet Chocolate Chips: Give that rich chocolate punch that pairs so well with peanut butter and candy.

Tweak to Your Taste

One of the things I love about this Crumbl Monster Cookie Recipe is how flexible it is. You can easily switch up the mix-ins or add a little extra to suit your cravings or dietary needs. Customizing these cookies is part of the fun!

Nut-Free Variation: I’ve swapped peanut butter chips for white chocolate chips for allergen-friendly but just as tasty cookies.
Extra Chocolate Overload: Adding a handful of mini chocolate chips on top before baking amps up that chocolate punch.
Salted Caramel Twist: Drizzle a bit of salted caramel sauce over the cooled cookies for a decadent touch I adore on cozy nights.

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

Step 1: Prep Like a Pro

Start by preheating your oven to 325°F. Then grab a baking sheet and line it with parchment paper — this keeps the cookies from sticking and makes cleanup a breeze. I always make sure everything’s ready before mixing to keep the process smooth.

Step 2: Cream the Butter & Sugars

I throw the cold butter, brown sugar, and granulated sugar in my mixer or bowl and beat it until it’s light and creamy—this takes about 3-4 minutes. It’s worth spending this time because well-creamed butter and sugar help give the cookie its wonderful texture.

Step 3: Incorporate the Egg and Vanilla

Add your egg and vanilla extract to the bowl and mix until everything’s combined. This step is quick but important to get an even dough.

Step 4: Mix in Dry Ingredients & Chips

Sift together your flour, baking soda, and salt, then add this to the wet ingredients. Mix just until you don’t see the flour anymore—overmixing can make cookies tough. Then, gently fold in the M&M’s, peanut butter chips, and chocolate chips so they don’t break apart but get evenly distributed.

Step 5: Scoop and Bake

I use a large cookie scoop to get even portions (about 8 cookies). Place them spaced on your baking sheet and gently press each ball down to about an inch thickness — this helps them bake evenly without spreading too much. Pop them in the oven for 12-13 minutes. You’ll want to pull them out when the edges start to set, but the middles still look a tiny bit soft.

Step 6: The Cherry on Top

Right when they come out of the oven, press a few extra chocolate chips, peanut butter chips, and M&M’s on top for that eye-catching finish. Let the cookies cool on the baking sheet for about 20 minutes — I promise this wait is worth it because it lets the cookies fully set up, soft but sturdy.

Pro Tips for Making Crumbl Monster Cookie Recipe

Soft Butter, Not Melted: Cold butter won’t cream well; softened butter makes all the difference for cookie texture.
Don’t Overmix the Dough: I learn the hard way that folding in flour just until combined keeps cookies tender.
Add Mix-Ins Last: This avoids crushing the candies and keeps the cookie looking vibrant and colorful.
Let Cookies Cool Fully: Resist the urge to grab one hot from the oven—it sets the cookie perfectly without falling apart.

How to Serve Crumbl Monster Cookie Recipe

Garnishes

I love adding a few extra chocolate chips and M&M’s pressed into the top of each cookie right out of the oven because it creates a glossy, colorful look that makes the cookies even more inviting. Sometimes, I dust a tiny bit of flaky sea salt on top for a nice sweet-salty contrast.

Side Dishes

These cookies pair like a dream with a cold glass of milk or a creamy vanilla latte. If it’s brunch, I’ve even served them with fresh fruit for a balance of rich and fresh flavors.

Creative Ways to Present

For parties, I stack these cookies on a rustic wooden platter, alternating layers with parchment paper and popping some colorful mini cupcakes or milk shooters around for a fun dessert board vibe. Wrapping individual cookies in cellophane tied with twine makes a sweet homemade gift that everyone raves about!

Make Ahead and Storage

Storing Leftovers

I usually store leftover monster cookies in an airtight container at room temperature if I plan to eat them within 3-4 days. It keeps them soft and fresh enough, but for longer freshness, refrigeration works best in my experience.

Freezing

These cookies freeze beautifully! I place them individually on a tray first to freeze solid, then transfer to a zip-top bag. When I’m ready for a treat, I let them thaw at room temperature or warm them slightly in the microwave—it brings back their soft, melty magic.

Reheating

To reheat, a quick zap in the microwave for about 10-15 seconds is my go-to. It softens the cookie perfectly without drying it out. Just watch closely because every microwave is different!

FAQs

Can I use unsalted butter for this Crumbl Monster Cookie Recipe?

Absolutely! If you use unsalted butter, just make sure to keep the 1/3 teaspoon of salt in the recipe to balance flavors. Salt is important to bring out the sweetness and enhance the overall taste.
Can I substitute other mix-ins for the peanut butter chips?

Yes! If you’re allergic to peanuts or just want to switch things up, try white chocolate chips, butterscotch chips, or even extra semi-sweet chocolate chips. It’s your cookie—make it yours!
Why do the cookies spread too much sometimes?

This can happen if the butter is too soft or melted, or if the dough is too warm when you bake. Make sure the butter is just softened (not melted), and chill the dough for about 15 minutes if your kitchen is super warm before baking.
How do I keep my Crumbl Monster Cookies soft for longer?

Store them in an airtight container with a slice of bread inside—the bread helps keep the cookies moist. Also, refrigerating them and reheating before eating keeps that soft texture intact.
Can I make this dough ahead of time?

Definitely! After mixing the dough, wrap it tightly and refrigerate for up to 24 hours. When ready, scoop and bake as directed. The flavors actually deepen when it rests.
