No-bake monster cookies are my go-to Halloween lifesaver. I first made them during a chaotic school bake sale week, when the oven was broken, and I had zero time. What came out of that last-minute scramble was a batch of gooey monster cookies that became an instant favorite. They’re crunchy from the chow mein noodles, sweet and sticky with butterscotch and marshmallow, and a total hit with kids. Plus, no baking required—just melt, mix, and shape! You get the fun of decorating Halloween monster cookies with edible eyes, but without the mess of frosting or complicated steps. They’re perfect for busy weeknights, last-minute party snacks, or spooky movie marathons.

Step-by-Step Instructions
Prep Your Station
Line a baking sheet with wax paper and have sugar eyes ready. These cookies set fast, so you need to act quickly once mixed.
Melt the Base
In a large pot over low heat, melt the peanut butter and butterscotch chips. Stir constantly to avoid burning.
Add the Mix-ins
Stir in the marshmallows and chow mein noodles. Combine until the marshmallows begin to melt but still leave some visible for that gooey effect.
Shape the Cookies
Working quickly, drop spoonfuls of the mixture onto wax paper. Immediately press sugar eyes into each mound before it cools.
Cool and Serve
Let cookies cool completely (10–15 minutes) before transferring to a plate. Enjoy your no-bake Halloween monster cookies with a big smile!
Pro Tips for Perfect No-Bake Monster Cookies
- Work fast. Once off heat, the mix firms quickly.
- Don’t over-melt the marshmallows—some gooeyness is part of the charm.
- Use wax paper for easy removal.
- Decorate immediately. Sugar eyes won’t stick once the mixture hardens.
- Crunch matters. Chow mein noodles give monster cookies their signature bite.
Delicious Variations
- Gooey Chocolate Monster Cookies: Replace butterscotch chips with semi-sweet chocolate.
- Spooky Mummy Cookies: Use white chocolate and mini licorice strips.
- Monster Cookie Pops: Insert lollipop sticks before the cookies harden.
