Why Are Monster Cookies Called Monster Cookies
Monster cookies are peanut butter, an oatmeal cookie that is loaded with sweet candy-coated M&M’s and chocolate chips.
Frankenstein called these monster cookies because they are a mashup of all the different cookie mix-ins.
Now just cause these get their name from Frankenstein doesn’t mean these only can be eaten around Halloween.
This is a cookie that is a treat all year round!
Everything you need to make Monster Cookies from scratch
- 1 ½ cups of creamy peanut butter
- 1 cup of sugar
- 1 cup of brown sugar
- ½ cup of softened butter
- 1 tbs. sour cream
- 3 eggs
- ½ tsp. vanilla extract
- 4 ½ cups of rolled oats (not the quick-cooking variety)
- 2 tsp. baking soda
- 1 cup of chocolate chips
- 1 cup of regular or baking M&M’s
Directions
- Preheat your oven to 350 degrees.
- Mix the eggs, sugar, and brown sugar in a large bowl. Mix well.
- Next, add the vanilla extract, peanut butter, butter, and sour cream. Mix well.
- Add in the two tsp. of baking soda.
- Slowly fold in your 4 ½ C. of rolled oats, mixing well.
- Next, add in your 1 cup of chocolate chips and ¾ of the M&M’s.
- Drop by large tablespoon onto a cookie sheet (I like to line mine with foil for easy cleanup) and gently press down into a more rounded shape. Press some of your extra M&M’s into the top of the cookie dough.
- Bake for 10-12 minutes. Cookies will turn golden brown. Try not to overbake. They are even better if a little bit undercooked and not crunchy.
*Makes approximately three dozen cookies. Store in an airtight container for 1-2 weeks. These cookies also freeze well.
What Is The Best Oats To Use For This Cookie Recipe
Old-fashioned rolled oats are recommended.
If you use quick oats, you will lose the flavor behind the oatmeal in the cookies.
Plus, rolled oats offer a nice chewy texture to the cookies that you can’t get without them.
To me, they are the best part of the cookie!
Do You Need To Refrigerate Cookie Dough Before Baking
This is a drop cookie, meaning you do not have to refrigerate the cookie dough like a classic sugar cookie.
This recipe is simple because you just whip it up, preheat the oven, and bake.
It is a great way to have a dessert to serve up after dinner without needing to refrigerate the dough overnight.
This is another reason why we love these cookies so much.

Can Monster Cookies Be Frozen
You can freeze the cookie dough raw to save for later or freeze the cookies themselves once baked and cooled.
To freeze it raw, I roll the dough up into a log, and then wrap it tightly and place it in an airtight freezer bag.
You could also make scoops, so all you have to do is drop the cookie balls on a baking sheet.
You can cook the dough from frozen. Just add a little extra minute or two to baking, as it will take a bit more to thaw before it bakes up.
For freezing the pre-made cookies, just allow the cookies to fully cool.
Then place in the freezer for up to three months. Then just thaw on the counter when you want to eat a cookie.

My first thought, going by the name, was a Halloween treat. However, I think these would be great for any day!!

These monster cookies look delish! Pinned 🙂

OMG! These look so delicious. I can’t wait to make them. I’m thinking about making them tonight.
Kristi says
Since some in my family need gluten free, I made these with gluten free Chex oatmeal and they were delicious! My entire family loved them and didn’t even know they were gluten free 🙂 the Chex oatmeal is fine and very similar to real oats.
Christy says
No flour?
T Worthey says
Nope, no flour needed for this one Christy!
L Allis says
My mom used to send these to me when I was stationed overseas thirty years ago! They freeze well and defrost in the microwave. A great cookie!
T Worthey says
Oh wow!! You have a great Mom! Thanks for sharing, and yes great cookies!!
Claire says
These did not hold together for me either time I’ve made them. They fall apart easily. Any tips for a novice? Great flavor.
Christy says
What will happen if quick oats are used?
Meredith DuHamel says
I have been making these cookies since the 1970s! They really are delicious and the recipe makes a huge amount! You can add other ingredients if you want, ie, raisins, nuts, rice crispies. A very versatile recipe.
Jill Ginavan says
Hello, Wortheys! Last Christmas, I made these marvelous Monster Cookies and gave them to friends and family as gifts, and they were a big hit. I think of them as Monster “Christmas” Cookies because, to me, they look like they are covered in Christmas tree lights! I am actually planning to bake some today to give out as gifts again this year. These cookies freeze very well, too, which is an added plus. Well into last January or February, I would occasionally pull one of them out of the freezer and have it for breakfast with my morning coffee! I hope all is well in your dear family, and may you all have a very Sweet and Merry Christmas. God bless!
T Worthey says
Good Morning Jill,
Oh, that’s AWESOME!! Thank you for coming back and letting us know they were a huge hit! I never thought about them as Christmas cookies or a gift, but that’s a great idea! Merry Christmas to you too!
Caylee says
These look and sounded delicious but they did not turn out on any of my attempts. They flattened out like pancakes and crumbled apart. I cooked them as long as I could- the tops began to turn dark brown- but the cookie was still incredibly underdone. Any thoughts on what I’m doing wrong? Thanks.
Kylina says
I was puzzled by no flour… tried making them today and I triple checked that I followed everything correctly and they are awful. Just melted into a goopy mess because there is no substance holding the ingredients together!
Definitely do not make this recipe and waist the expensive ingredients. Look for another recipe containing flour!
T Worthey says
Hi Kylina!
Thanks for stopping by and trying out this recipe. I am sorry it did not turn out well, but you can make Monster Cookies without the flour. I was curious by your comment, so I went to find other recipes for Monster Cookies from popular sites like Food Network, and they also don’t use flour. I think the biggest thing is going in order of the ingredients. I would love for you to try this again, and we would be willing to send you a gift card to buy the ingredients and give it another try. Let me know!
