Ingredients You’ll Need
All the ingredients here come together to create the perfect balance of sweetness, crunch, and a little salty twist that surprises you in the best way. Be sure to grab good-quality butter and fresh oats for best results.
- Salted butter: Using salted butter enhances the flavor, but if you only have unsalted, just add a pinch more salt.
- Dark brown sugar: This adds deep molasses notes that make the cookies extra moist and flavorful.
- Light brown sugar: Balances sweetness; you can use all dark brown sugar for a richer taste.
- Large eggs: The eggs help bind the dough and add richness; don’t skip the extra yolk—it’s a game changer for texture.
- Vanilla extract: A must-have for that warm, comforting aroma.
- All-purpose flour: The base of your cookie dough; make sure it’s measured well to avoid dense cookies.
- Baking soda: Helps the cookies rise just enough without puffing up too much.
- Baking powder: Works alongside baking soda to give a nice lift and tender crumb.
- Kosher salt: Balances sweetness and enhances all other flavors.
- Old fashioned oats: Adds chewiness and heartiness that make these cookies so satisfying.
- Halloween M&M’s: The festive colors and chocolatey pops make these cookies special and seasonal.
- Mini pretzel sticks: Crushed for a salty crunch that pairs beautifully with the sweet elements.
- Semi-sweet chocolate chips or chunks: Melty, rich chocolate accents that bring everything together.
- Candy eyes: The signature spooky detail that turns standard cookies into monsters!
Variations
One of the things I enjoy most is tweaking this Halloween Monster Mash Cookies Recipe to fit different moods or dietary needs. Whether you’re after something a little less sweet or want to toss in a new flavor element, it’s super flexible.
- Gluten-Free Version: I swapped regular flour for a gluten-free all-purpose blend and it worked like a charm—still chewy and delicious!
- Nutty Twist: Once, I added chopped toasted pecans for extra crunch, and my family begged me to keep it forever.
- Vegan Adaptation: Use vegan butter and a flax egg instead of regular eggs, and the cookies still turned out surprisingly rich and tasty.
- Spice It Up: Adding a pinch of cinnamon or pumpkin pie spice makes it feel even more autumnal, which I love for fall gatherings.
How to Make Halloween Monster Mash Cookies Recipe
Step 1: Cream and Combine Everything
Start by preheating your oven to 350°F (175°C) and lining a baking sheet with parchment paper—this really prevents sticking and cleanup is a breeze. Then, beat the softened butter with both dark and light brown sugars until the mixture is light and fluffy; this took me about 3-4 minutes with my hand mixer. Next, beat in the eggs one at a time, along with an extra egg yolk, which makes your cookies perfectly tender with a slight chew.
Step 2: Mix in Dry Ingredients and Oats
In a separate bowl, whisk together the flour, baking soda, baking powder, and kosher salt. Gradually add this dry mix to the butter mixture, beating just until combined. Then, stir in the old fashioned oats by hand so you keep their wonderful texture intact. This part gives the cookies that classic hearty bite that’s so satisfying.
Step 3: Fold in the Fun Stuff
Carefully fold in 1 cup of the Halloween M&M’s, crushed mini pretzel sticks, and the chocolate chips or chunks. I like to reserve some M&M’s and all of the candy eyes for decorating the tops after the initial bake—it creates a cool “monster eye” effect that’s just too cute to resist.
Step 4: Shape and Bake
Roll the dough into balls about 1/4 cup size—you can use a cookie scoop for consistency. Place them 3 inches apart on your prepared sheet to give them room to spread. Bake for 8 minutes, then rotate your pan to ensure even cooking and bake for another 2 minutes. Now, pull the pan out and gently press the remaining M&M’s and candy eyes onto the tops of each cookie, then pop them back in for another 2-3 minutes. This timing is key to avoid melting the candy eyes too much but getting the cookies perfectly finished.
Step 5: Cool and Enjoy
Once out of the oven, let the cookies cool right on the baking sheet for at least 10 minutes. They continue cooking slightly and firm up without losing their chewy center. I love eating them warm with a cold glass of milk – they’re especially good fresh out of the oven!
Pro Tips for Making Halloween Monster Mash Cookies Recipe
- Room Temperature Butter: Let your butter soften to room temp before mixing; it helps create the ideal creamy texture for your dough.
- Don’t Overmix: Once you add the flour, mix until just combined to keep your cookies tender rather than tough.
- Spacing Matters: Give your cookie dough balls plenty of room to spread on the baking sheet or they’ll bake into one big monster mash!
- Candy Eyes Last: Adding the candy eyes towards the end of baking prevents them from melting and keeps their shape intact.
How to Serve Halloween Monster Mash Cookies Recipe
Garnishes
I like to keep it simple and playful by using extra candy eyes on top to accentuate the monster theme. You can also drizzle some melted white or orange chocolate for extra flair if you’re feeling creative. Sprinkles shaped like bones or pumpkins work beautifully too and add some crunch and color.
Side Dishes
These cookies are best paired with a cold glass of milk or a cozy cup of hot chocolate—especially on a chilly Halloween night. At parties, I like to set them alongside some fruit snacks or popcorn for a fun snack table full of textures and flavors.
Creative Ways to Present
I’ve had great success arranging these cookies on a platter decorated with mini pumpkins, fake spider webs, and dark-colored napkins for a spooky vibe. For kid parties, make a cookie “monster bouquet” by sticking them onto skewers placed in a vase or foam block. It’s a fun surprise that kids love!
Make Ahead and Storage
Storing Leftovers
I store leftover Halloween Monster Mash Cookies in an airtight container at room temperature. They stay just as chewy and delicious for about 3 to 4 days—if they last that long in your house! For best texture, keep them separate from any moisture-heavy foods.
Freezing
If you want to make these ahead of time, the dough freezes beautifully. I freeze the dough balls on a baking sheet first, then transfer them to a freezer-safe bag. When ready, just bake them straight from frozen, adding an extra minute or two to the baking time.
Reheating
To bring back that fresh-baked warmth, I pop cold cookies into the microwave for about 10-15 seconds or warm them in a 300°F oven for 5 minutes. This freshens up the melty chocolate and makes them taste like they just came out of the oven.
FAQs
-
Can I use regular M&M’s instead of Halloween M&M’s?
Absolutely! Regular M&M’s work just as well in this recipe if you don’t have the Halloween-themed version. The only difference is that you won’t get the seasonal colors, but the taste and texture will still be fantastic.
-
What makes the candy eyes not melt completely while baking?
The trick is to add the candy eyes halfway through the baking process, rather than mixing them into the dough initially. This way, they get slightly warmed but keep their shape and fun “monster” look.
-
Can I make these cookies gluten-free?
Yes! Use a gluten-free all-purpose flour blend that measures cup-for-cup like regular flour. I’ve tried this swap with success — just be sure to stick to the blend’s instructions for the best results.
-
How do I prevent cookies from spreading too much?
Make sure your butter is softened but not melted, and measure flour carefully. Chilling the dough for 15-20 minutes before baking can also help keep the cookies from spreading too thin.

This Halloween Monster Mash Cookies Recipe has become one of my go-to treats every spooky season. They’re playful, packed with flavor and texture, and bring out the kid in all of us.

Add-ins and Toppings
- 1 1/4 cups Halloween M&M’s
- 1 cup mini pretzel sticks, crushed
- 1 cup semi-sweet chocolate chips or chunks
- Candy eyes (for decorating)
Instructions
- Preheat oven and prepare pan: Preheat your oven to 350° F (175° C). Line a baking sheet with parchment paper to prevent sticking and ensure even baking.
- Mix wet ingredients: In a large bowl, beat together the softened butter, dark brown sugar, light brown sugar, and vanilla extract until creamy and well combined. Then, add the eggs and egg yolk one at a time, beating well after each addition until fully incorporated.
- Add dry ingredients and oats: In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, and kosher salt. Gradually add this dry mixture to the wet ingredients, mixing until just combined. Fold in the old fashioned oats gently into the dough.
- Incorporate mix-ins: Carefully fold in 1 cup of the Halloween M&M’s, crushed pretzel sticks, and chocolate chips to the dough, distributing evenly without overmixing.
- Form dough balls: Using a 1/4 cup measuring scoop, roll the dough into balls and place them onto the prepared baking sheet. Make sure to space them about 3 inches apart to allow for spreading.
- Bake initial cookies: Bake the cookies for 8 minutes, then rotate the baking sheet to ensure even cooking, and bake for an additional 2 minutes.
- Add toppings and finish baking: Remove the baking sheet from the oven and gently press the remaining M&M’s and candy eyes into the tops of the cookies to create a monster effect. Return the cookies to the oven and bake for another 2 to 3 minutes until the edges are golden and the centers are set.
- Cool and serve: Remove the cookies from the oven and allow them to cool on the baking sheet. They will continue to cook slightly as they rest. Enjoy warm or cool completely before storing in an airtight container for up to 4 days.
Notes
- Make sure the butter is at room temperature for easier mixing and better texture.
- Spacing cookies well on the baking sheet avoids them merging into each other as they spread.
- Pressing candy eyes and extra M&M’s on after partial baking keeps them from melting completely and helps maintain their shape.
- The cookies will remain slightly soft in the center; allow cooling for firmer texture.
- Store cookies in an airtight container at room temperature for up to 4 days to maintain freshness.
- This recipe makes approximately 20 medium-sized cookies.
