Festive and easy, these Halloween Cookies are an absolute must-make for your friends and family for a spooky movie night at home or for the Halloween block party!

No tricks here, just a delicious treat! These cookies are filled with orange, purple, white, and green M&Ms (the seasonal “Ghoul Mix” M&M bags) for the most adorable Halloween cookies. We even added edible googly eyes to some of the cookies to create perfect monster cookies! How cute are they?!

They’re so easy to make, too. No crazy decorating with royal icing required! Plus, these are so fun to get the kids involved with baking up a spooky treat together.

Sprinkle of Science
How to Make Halloween Cookies
Ingredients for Easy Halloween Cookies:
- All-purpose flour – Be sure to measure your flour correctly! If you add too much flour, you may end up with tough cookies that don’t spread, are cakey, dry, or taste bland.
- Black Cocoa powder or Dutch-process cocoa powder – Black cocoa can be ordered online and will provide that festive deep dark color. It also makes the cookies taste like Oreos! If you can’t find Black cocoa, feel free to use Dutch-process cocoa powder instead. Learn more about Dutch-process cocoa here. Be sure to also measure your cocoa correctly, as cocoa powder is a drying ingredient and too much will dry out your cookies.
- Baking soda & baking powder – Check out my Baking Soda vs. Baking Powder article to learn about the surprising differences between these two leaveners!
- Cornstarch – To keep the consistency of these cookies soft and tender.
- Salt – Enhances the flavor.
- Granulated sugar and light brown sugar – For sweetness, moisture, and flavor. Do not reduce the sugar – learn why here.
- Butter – Always use unsalted butter in baking, at a cool room temperature (around 67°F is perfect). Learn why butter temperature is important in baking here.
- 1 egg – At room temperature.
- Vanilla extract – For flavor.
- White chocolate chips & Halloween-themed M&Ms – For flavor, and to bring a super fun Halloween-y flair to our cookies!
- Candy googly eyes – For so much additional fun!!

What Type of Cocoa Powder to use for Double Chocolate Halloween Cookies?
I recommend using Black Cocoa for the best visual effect and for a tasty flavor (think Oreos – not super rich in chocolaty flavor, but a distinct flavor nonetheless). It can be difficult to source in stores but can be purchased easily online here. Alternatively, you can also use Dutch-process cocoa – just note that this will make your cookies lighter and more brown in color. My favorite brands of Dutch-process cocoa powder are E. Guittard, Penzeys, Bensdorp, or Valrhona. Regardless of cocoa type, be sure to sift it to avoid clumps of cocoa in your cookies!
How to Make Double Chocolate Halloween Cookies:
- Cream the butter and sugars. In the bowl of a stand mixer fitted with the paddle attachment, beat the butter and sugars together on medium speed until light and fluffy, about 3 minutes.
- Add the vanilla and egg. Scrape the bowl down before adding in the vanilla extract and the room temperature egg, beating well to combine.
- Combine the dry ingredients. Sift together the flour, cocoa, cornstarch, salt, baking soda, and baking powder. Gradually add in the dry ingredients to the wet ingredients and beat until a slightly sticky dough forms.
- Add the chocolate. Fold in the white chocolate chips and M&Ms with a rubber spatula.
- Portion out the cookies and decorate. Using a large spring-loaded scoop, drop 3-tablespoon sized balls of dough onto the prepared baking sheets, spacing them at least 2 inches apart. Dot the balls of cookie dough with extra chips, M&Ms, and candy eyeballs.
- Bake. At 350°F for about 12 minutes, until puffy but still soft, being careful not to overbake.
Allow to cool slightly on the baking tray. Allow to cool on the baking sheet for 5 minutes, before removing to a wire rack to cool completely.

Can I Change up the Mix-Ins?
Yes! You can absolutely switch out the white chocolate chips and Halloween-themed M&Ms for just about whatever you like! Just be sure to keep the total weight (or volume) the same as written in the recipe as well as using similarly sized mix-ins so the cookie dough balls stay together. Here are some Halloween cookie mix-in ideas:
- Dark chocolate chips
- Semi-sweet chocolate chips
- Reese’s Pieces
- Well-chopped candy bars
Can I Make These into Halloween Cookie Bars?
Yes! These work beautifully as cookie bars. Here’s how:
Preheat oven to 350°F. Line a light-colored metal 8×8-inch baking pan with parchment paper or aluminum foil and use metal binder clips to secure in place. Make the recipe as instructed, then place the cookie dough in the prepared pan. Decorate the top with additional M&Ms, white chocolate chips, and candy eyeballs as desired. Bake for 25-30 minutes, or until the edges appear set but the center still jiggles slightly. Allow to cool before removing from the pan and slicing into 16 bars.
How to Store Double Chocolate Halloween Cookies
These are best enjoyed when fresh, but they will keep in an airtight container at room temperature for up to 5 days. Be sure they are completely cooled before storing. See right below for my top cookie storage tips!
How to Keep Cookies Soft
To keep your baked Halloween Cookies soft, you can add an apple wedge, piece of bread, or a tortilla on the top and bottom of the cookies to the container a day or two after baking them, or whenever you find the texture beginning to harden. The moisture from this will migrate to your cookies, making them soft and chewy again. A tortilla is a favorite of mine because it takes up much less room than a slice of bread and doesn’t transfer any flavors or aromas like an apple wedge can.
Alternatively, you can freeze the cookie dough so you can just bake off what you need, then store the rest in the freezer until you next crave fresh chocolaty cookies! More on this below.
Can you Freeze Double Chocolate Halloween Cookies?
I love the taste of cookies straight from the oven best (who doesn’t!?). I always keep pre-scooped balls of various types of cookie dough in a resealable bag in my freezer, so I can bake cookies off and have them warm from the oven in a matter of minutes whenever I want! Find all my tips for freezing cookie dough, and baking from frozen here.

I made these and they were chocolately and yummy. We couldn’t eat just one
These were easy to make, fun and delicious!! I personally did not need to make any adjustments for high altitude.
These cookies are super easy to make. My granddaughter and I had lots of fun making them.
These were great tried both peanut butter and plain mnms and preferred the plain!
“These are like a monster exploded!” These are chocolatey delicious and so much fun! The brightness of the M&Ms will dull while baking, so if you want bright, quickly add more goodies after you pull them from the oven.
Soft and brownie like! All in the family enjoyed. From ages 2 to 63.
My 5 year old declared these the “best cookie eveeeeeeer!” He’s not wrong, they are absolutely delicious and will be made again!
These cookies were yummy, but a bit too intense for me…that’s just personal preference, as everyone else who had them loved them! Also, most of my eyeball candies sunk into the cookies. I guess I should have put them on after I baked the cookies. Overall, a very easy and fun recipe!
I made these in an 8 x 8 pan and they turned out perectly!! Baked to perfection and oh so chocolately. My husband raved about how delicious they are and of course I agree! This is a keeper and will make again.
Hi
Can I prepare them in advance and freeze prior to baking.
Hi Gabbi! Yes, absolutely! More tips on this can be found at the bottom of the pink tip box, right above the recipe 🙂
Yum yum! We had a family fun evening making and enjoying these cookies. The black cocoa adds amazing flavor!
These monster cookies are so much fun! And so tasty! I made them last year for a school party, and they were a huge hit! So I had to make them again this year for our Halloween bake sale. I made the dough ahead of time and froze the dough balls. I thawed them overnight in the fridge, so I could decorate them this morning. They baked up fast and delicious! Another keeper recipe from Tessa!!
