Ingredients You’ll Need

These ingredients combine to give you a cookie that’s rich, sweet, and satisfyingly crunchy. You’ll want to look for quality butter and fresh M&M’s to get the best flavor and texture. And don’t swap out the rolled oats — they’re key to keeping these cookies chewy but hearty.

• All-purpose flour: Provides structure; I always sift mine to avoid lumps.
• Baking soda: Helps the cookies rise just right without puffing up too much.
• Ground cinnamon: Adds a subtle warmth and depth of flavor.
• Kosher salt: Balances sweetness and enhances the other flavors.
• Unsalted butter: Softened to room temperature for creamy mixing; using salted butter is okay if that’s what you have, just skip the extra salt.
• Granulated sugar: Contributes to sweetness and crisp edges.
• Light brown sugar: Packed lightly to maintain moisture and chewiness.
• Large eggs: Room temperature eggs ensure better mixing and texture.
• Pure vanilla extract: Always worth using a good quality—it makes a big difference.
• M&M’s: Use standard or peanut M&M’s to add colorful bursts of chocolate and crunch.
• Unsalted peanuts: Roasted and unsalted keep the flavor balanced with a nice crunch.
• Rolled oats: Not instant or quick-cooking; rolled oats give perfect chewiness.
• Crushed pretzels: Adds a salty crunch and a fun twist that you might not expect but will love.

Variations

One thing I love about this Monster Cookies Recipe is how easy it is to tweak based on what’s in your pantry or your dietary needs. Feel free to swap out ingredients to suit your taste — that’s part of the fun!

• Nut-Free Option: I sometimes replace peanuts with sunflower seeds or extra pretzels when serving to someone with allergies, and they still turn out amazing.
• Gluten-Free: Use a gluten-free all-purpose flour blend and certified gluten-free oats to accommodate gluten intolerance.
• Chocolate Lovers: Add a handful of mini chocolate chips along with or instead of M&M’s for extra melty pockets of chocolate.
• Spiced Up: For a twist, I add a pinch of ground ginger or nutmeg along with the cinnamon to deepen the flavors.

How to Make Monster Cookies Recipe

Step 1: Prep Your Oven and Baking Sheets

Arrange your oven racks in the upper and lower thirds and preheat the oven to 350°F. I always line two large baking sheets with parchment paper, which helps the cookies bake evenly without sticking and makes cleanup a breeze.

Step 2: Mix Your Dry Ingredients

In a medium bowl, whisk together your flour, baking soda, cinnamon, and kosher salt until evenly combined. This step helps distribute the leavening agent and spices throughout the dough so every cookie tastes just right.

Step 3: Cream the Butter and Sugars

In a large bowl, beat softened butter, granulated sugar, and brown sugar on medium-high speed until the mixture is light and fluffy—this usually takes 2 to 3 minutes. It’s when you’ll start smelling that caramel-y, buttery goodness that makes you excited for the finished product.

Step 4: Add Eggs and Vanilla, Then Combine

Beat in the eggs one at a time along with the vanilla extract until everything is well incorporated. Then, on low speed, add your dry ingredients slowly so your dough doesn’t get overworked (you don’t want tough cookies!).

Step 5: Fold in the Fun Mix-Ins

Using your mixer on low speed or a sturdy spatula, gently fold in the M&M’s, peanuts, rolled oats, and crushed pretzels. You’ll notice the dough getting delightfully chunky and colorful. This is what makes monster cookies, well… monsters!

Step 6: Scoop and Arrange

Scoop 16 generous 1/4-cup sized balls of dough — I weigh mine around 65 grams if I’m being precise — and space them about 3 inches apart on your baking sheets. Give each ball a light gentle press with your palm to slightly flatten them; this helps the cookies spread just right.

Step 7: Bake and Cool

Bake for 16 to 18 minutes, rotating your baking sheets front to back and top to bottom halfway through so they brown evenly. When they’re done, edges should be set and golden, but centers will still be a little soft — that’s perfect. Let them cool completely on the sheets, which gives them time to firm up without drying out.

How to Serve Monster Cookies Recipe

Garnishes

I usually keep these cookies as-is because all the mix-ins give plenty of visual flair and texture, but if I’m serving them for a party, a light dusting of powdered sugar or a quick drizzle of melted chocolate elevates them beautifully.

Side Dishes

These monster cookies pair perfectly with a cold glass of milk or a cup of your favorite coffee. I’ve even served them alongside a scoop of vanilla ice cream for a fun dessert twist that my family goes crazy for.

Creative Ways to Present

For birthdays or special occasions, I like to stack these cookies as a “cookie cake” and decorate the top with more M&M’s or even edible gold dust for a wow-factor presentation. Wrapping individual cookies in colorful cellophane with fun ribbons is another favorite, especially for gifting.

Make Ahead and Storage

Storing Leftovers

I store leftover monster cookies in an airtight container at room temperature, which keeps them chewy and fresh for up to five days. If your kitchen is warm or humid, pop a slice of bread in the container to help maintain moisture.

Freezing

I’ve frozen the cookie dough balls before baking and had fantastic results — just shape the dough, freeze on the pan, then transfer to a freezer bag. When ready, bake straight from frozen, adding a couple of extra minutes to the baking time.

Reheating

To enjoy leftover cookies warm, heat them in the microwave wrapped in a slightly damp paper towel for about 15 seconds or a few minutes in a low oven (300°F). This refreshes their softness and brings out the flavors beautifully.
