- ½ cup granulated sugar
- ¾ cup packed brown sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour

How to Make Halloween Monster Cookies
1. Preheat the Oven
Preheat your oven to 350°F and line a baking sheet with parchment paper.
2. Cream the Butter and Sugars
In a large mixing bowl, beat together the softened butter, peanut butter, granulated sugar, and brown sugar until smooth and creamy.
3. Add the Wet Ingredients
Mix in the egg and vanilla extract until everything is well combined.
4. Add the Dry Ingredients
Add the flour, baking soda, and salt. Mix just until a soft cookie dough begins to form.
Fold in the oats.
5. Add the Halloween Goodies
Gently fold in the Halloween M&M’s, chocolate chips, and sprinkles.
Save a few M&M’s and chocolate chips to press onto the tops of the cookies before baking. This makes them look extra colorful and Pinterest-worthy!
6. Scoop the Cookies
Scoop approximately 2 tablespoons of dough per cookie and roll into balls.
Place them about 2 inches apart on your prepared baking sheet.
Press a few extra candies into the tops.
7. Bake
Bake for 10–12 minutes, or until the edges are lightly golden but the centers still look slightly soft.
Don’t overbake them! They’ll continue to set as they cool.
8. Make Them Spooky
Immediately after removing the cookies from the oven, gently press candy eyeballs into the warm cookies.
Let the cookies cool on the baking sheet for about 5 minutes before transferring them to a cooling rack.
The Secret to Soft and Chewy Monster Cookies
The biggest secret is simple: don’t overbake them.
Take the cookies out when the edges are set but the centers still look slightly underdone. As they sit on the hot baking sheet, they’ll continue baking without becoming dry or crunchy.
Brown sugar also helps give these cookies their irresistible soft and chewy texture.
Make Them Extra Halloween-Themed 🎃
Want your monster cookies to look even spookier?
Try mixing in orange, purple, green, and black sprinkles. You can also add mini peanut butter cups, white chocolate chips, Halloween-shaped sprinkles, or even chopped chocolate candy bars.
And don’t be shy with the candy eyeballs—the more mismatched eyeballs each cookie has, the more “monster” they look!
Storage
Store your Halloween monster cookies in an airtight container at room temperature for up to 4–5 days.
To keep them extra soft, make sure the container is tightly sealed.
Can You Freeze Monster Cookies?
Yes!
Once completely cooled, place the cookies in a freezer-safe container or bag and freeze for up to 3 months.
You can also freeze balls of unbaked cookie dough. When you’re ready for fresh cookies, bake them straight from frozen and simply add another minute or two to the baking time.
