How to Make the Recipe
1. Preheat the Oven
Preheat your oven to 350°F (175°C). Line your baking sheets with parchment paper to prevent sticking.
2. Cream the Butter and Sugars
In the bowl of a stand mixer fitted with the paddle attachment, beat together the unsalted butter, granulated sugar, and brown sugar on medium speed for about 3 minutes until light and fluffy. Don’t forget to scrape down the sides!
3. Add the Egg and Vanilla
Add the vanilla extract and the room temperature egg to the butter-sugar mixture, and beat well until fully combined.
4. Mix the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, black cocoa powder, cornstarch, fine sea salt, baking soda, and baking powder.
5. Combine Wet and Dry Ingredients
Gradually add the dry ingredients to the wet ingredients, mixing on low until just combined. You’ll end up with a slightly sticky dough.
6. Fold in the Mix-Ins
Using a rubber spatula, gently fold in the white chocolate chips and Halloween M&Ms.
7. Scoop and Bake
Using a large cookie scoop (about 3 tablespoons per cookie), drop the dough onto the prepared baking sheets, spacing them 2 inches apart. Press in a few extra M&Ms, white chocolate chips, and candy eyeballs on top for that fun, spooky look.
8. Bake
Bake the cookies for about 12 minutes, just until they’re puffy but still soft. Be careful not to overbake! Let them cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

How to Serve
These cookies are perfect for a Halloween party spread or just as a fun treat at home. Serve them with a glass of milk (because let’s be real, cookies and milk are a must). And trust me, they’re even better when shared with friends or family during a scary movie night!
Make Ahead
You can make the cookie dough in advance and freeze it for up to 3 months. Just scoop the dough into balls, freeze on a baking sheet, and then transfer to a freezer-safe bag. Bake straight from frozen, just add an extra minute or two to the baking time.
FAQs
Can I use regular cocoa powder instead of black cocoa?
Absolutely! Dutch-process cocoa works great if you can’t find black cocoa. The color will be lighter, but the cookies will still taste delicious.
How do I store leftovers?
Store the cookies in an airtight container at room temperature for up to 5 days. You can also freeze the baked cookies for up to 3 months.
Can I make these without the candy eyeballs?
Totally! The candy eyeballs are just for fun, but the cookies will still be spooky and delicious without them.
