Easy Halloween Cookies
How do you like the little monster faces on these cute Halloween cookies? I saw the little eyeballs at the grocery store and knew I had to come up with an easy Halloween cookie idea. The Halloween M and M's are also perfect for this monster cookie recipe. I love this mix with the orange, green and purple candies.

The Best Monster Cookie Variations:
This is a great monster cookie recipe, the best if I do say so myself. It can easily be adapted for other holidays with other colors of M and M's or seasonal candies. One of my favorite versions of this cookie is using crushed Cadbury Eggs, talk about a fun cookie. These chocolate chip Halloween cookies are perfect for any party!
Just about any combination of seasonal candy and cute sprinkles will do the trick.
How to make this cute Monster Cookie Recipe
- Preheat the oven to 325 degrees
- In an electric mixing bowl (I used a Kitchen Aid with this cookie recipe.) Add the room temperature butter and sugars, and beat until fluffy.
- Add the vanilla and eggs and mix again
- Add the baking soda, baking powder, salt, and rolled oats, and mix again until everything is combined.
- Mix in the flour
- Pour in the chocolate chips and mix again
- Grease a cookie sheet
- Shape the monster cookie dough into 1 ½" balls
- Roll the top part of the ball in your favorite sprinkle.
- Put the cookie dough ball on the greased cookie sheet with the sprinkle side up
- Bake in a preheated 325-degree oven for 10-12 minutes or until the edges are slightly golden.
- As soon as you take the cookies out of the oven, press the eyeballs and M and M's into the hot cookies.
- Let the cookies cool on the pan for a few minutes before removing them.

Make-Ahead Cookie Dough
- Fridge- You can make the cookie dough ahead of time. It will last in the fridge for a couple of weeks in an airtight container.
- Freezer- Like most cookie doughs, this dough can be frozen and baked at a later date. Simply scoop into balls and place on a parchment-lined pan, and freeze until solid. Once frozen, remove from the cookie sheet and place in a freezer bag. They can be stored in the freezer for 3-4 months.
- To Bake Frozen Cookies: Defrost for an hour or two in the fridge and bake as directed. If the dough is very cold, you may need to add a minute or two of cook time.
Storing Baked Cookies
You can also store the cookies already baked.
- Airtight Container- If you want to store the cookies already baked, just place them in a container with a lid. They will stay fresh for a few days.
- Freezer- If you haven’t tried this method, you’re missing out. Cookies freeze really well and are so fun to grab out of the freezer and enjoy. Let them thaw for a few minutes, and you’ll have an extra chewy cookie to enjoy. Cookies can remain in the freezer, in an airtight container, or freezer bag for up to 3 months.
Optional Add-Ins
- Nuts: just about any kind! Toast them in a saute pan for about 5 minutes first, or lightly toast them in the oven before adding to the dough.
- M&M’s: plain, peanut, coconut, peanut butter, all sizes, shapes, and flavors! A really fun and cute addition.
- Dried Fruit: cranberries, raisins, blueberries, strawberries, flaked coconut (super yummy when it’s toasted), and even sliced & dried bananas!
- Extra Crunch: try crushing some whoppers, crushed potato chips, or pretzels,
- Flavored Morsels: butterscotch chips, chocolate chips, caramel bits, or Heath pieces.

There are many possibilities, but the most common are probably either your pan was too hot or you could have forgotten the baking soda/powder.
