This big batch of monster cookies is one of our family’s absolute favorite recipes. Loaded with peanut butter, oatmeal and chocolate candies, they turn out chewy and delicious. This recipe makes a lot of deliciously chewy cookies, but if it’s too many you can freeze the dough or the baked cookies for a quick and easy treat any time you want one.
If you are looking for a monster batch of chewy cookies that are loaded with peanut butter, oatmeal and chocolate, you are in the right place. They are wonderful for after school snacks, perfect for a party or you can use holiday colored M&Ms to make them festive.
These cookies are flour free, so can be made naturally gluten free if you use gluten free oatmeal. They pretty much are the perfect cookie, so making a large batch just makes sense.
I am surprised it has taken me this long to get around to posting our family favorite recipe for monster cookies on the blog. We have had them a number of times in the past year, I’ve even taken pictures of a few.
I think the problem is that MiMi is normally in charge of making them instead of me, so for whatever reason they haven’t been posted yet. It is high time we get to them, better late than never I suppose!
Why You’ll Love This Recipe
- It makes a lot of delicious cookies with the perfect soft and chewy texture.
- There is no chill time, the dough is ready to bake right away!
- You use melted butter, so the dough comes together quickly and easily.
The Original Monster Cookie Recipe
We were introduced to this recipe when my parents’ old parish put out a cookbook in 2004. Norma Wellman Obert submitted a recipe for monster cookies and it made a monstrous amount of cookies!
Her recipe called for 12 eggs, 3 pounds of peanut butter, a pound of butter and 18 cups of oatmeal (plus all of the other ingredients or course.) Talk about a batch of cookies, you would need one heck of a large bowl!
She said her recipe would make 15-20 dozen when dropping them by the tablespoonful. I believe it!
It would actually be fun to make that size batch some time. You could bake some off right away and freeze the rest in balls for later.
Then you could have cookies as you want them! Usually we show great restraint and make them a half batch at a time. Don’t get me wrong, that is still a LOT of cookies and there are plenty to freeze if you like.
Pro Tip: If you want to make the original monster cookie recipe with a dozen eggs, just use the tools in the recipe card to double the ingredients. You can click the 2x button or change the serving size to have the math done for you.
Tips and Tricks
A word of warning: these really are easy enough to mix by hand, so you might want to go that route. The batch is so big, it almost came out of my 4.5 quart mixer.

The mixer was so full, I had to stir in the M&Ms by hand anyway because they were getting thrown out of the bowl. So, pull out the biggest mixing bowl you have and a sturdy spoon and just go for it!
If you have a 6 quart mixer you can make the full batch in the stand mixer. So this is a good opportunity to go ahead and use it, though I still recommend stirring in the chocolate by hand.
Because monster cookies don’t have flour in them to help firm them up, they are very soft when they come out of the oven. Let them cool on the cookie tray for a few minutes before moving them to a wire rack to cool completely.
Anyway, I know there are quite a few recipes for monster cookies out there, but we are never disappointed with these. They have stood the test of time and we keep coming back for more!
Frequently Asked Questions
Why are they called monster cookies?
They are the Frankenstein of the cookie world, a mashup of all of the best stuff!
How do you store homemade cookies?
The cooled cookies store well at room temperature for up to a week, add a piece of sandwich bread if you want to keep them soft even longer. Put them in a freezer bag in the freezer for up to 3 months.
Can you freeze the dough?
Yes! You can freeze it in a chunk if you want. But I prefer to scoop the dough into balls and freeze them for an hour on a cookie tray.
Put the frozen dough balls in a freezer safe bag and put them back in the freezer.
When you are ready, pull a few out and put them on a baking tray. Add a minute or so to the bake time and bake them from frozen.
What other ingredients can be added?
Feel free to add all of your favorite cookie stir-ins, you can easily add a cup or two more to this base recipe. The easiest way to customize them is to adjust the baking chips you use.
You can try white chocolate chips, chocolate chunks, butterscotch chips, or even peanut butter chips for full on peanut butter flavor.
We know people who love raisins and nuts in their monster cookies but we prefer them to be all chocolate peanut butter oatmeal cookies.

Look forward to trying these for sure!
I do have a question tho….
Is it one pound each of M&M’s
And chocolate chips? Or 1/2 pound of each?
I usually use 1/2 pound of each, though the dough could probably take a bit more if you want extra chocolate in your cookies.
How fun is that?! I just found these on Sunday Suppers Back to School Snacks post. I used to love freezing some of this dough and baking it right before you kids got home from school so our home would smell so welcoming. Nothing better than a warm Monster Cookie and a glass of milk after a long day at school
It's hard to beat warm cookies and a glass of milk just about any time!
What a lot of cookies! I've never been much of a cookie maker, but I think I should make it an activity to do with the children.
My little guy loves to help make cookies! The recipe does make quite a few, but the dough does freeze really well so you can make a few at a time. Or make them all and become the favorite neighbor!
What a neat looking cookie! 🙂
Thanks for joining Cooking and Crafting with J & J!
They are the best!
These cookies look great! I am craving cookies now. Off to the store to buy the ingredients! Thanks so much for sharing at Inspiration Thursday!
It's hard to go wrong with cookies, especially these! Thanks, Lela!
These cookies look incredible! The recipe is huge but it would save so much time to whip up the whole batch and then freeze part of it for later. I like your idea of rolling it and balls before freezing, the kids could pull it out 6 or 12 and make fresh homemade cookies whenever they needed a snack. I think my mixer would have a hard time with the entire batch also perhaps you could just pour in half the ingredients and mix that up and while they're baking pour in the other half and mix those up. Definitely a recipe that needs pinned. I want to come back to this again and again thank you!
I love freezing them in balls like that. My mom used to literally bake them off 2 or 3 at a time some days! Luckily you really can do it by hand if you want. Because the butter is melted, it isn't terribly difficult. (says the one who almost had an eruption of monster cookie dough from the mixer!)
Those look yummy Carlee. It just so happens that we don't have a good monster cookie recipe! Thanks for sharing this one. 🙂
I hope you love these as much as my family does! My mom read this and told me I got the story all wrong about when we first started making them. Apparently she is waiting to correct me in an upcoming guest post. Moms are like that sometimes 😉
Yum yum yum! These look so cute and yummy ♥

Oh my, they are delicious every time! Thank you!
Ha. This is the recipe that caused me to go out and get a 6 quart mixer. When you kids were still at home we made these cookies often. Kristie's coworkers would even let her know if it had been a while since I made them a batch. I just made a monster cookie dip. I should share that too. I hear that it's addicting.
Yes! You have to share the dip, it was a hit at the party on Sunday! Now my coworkers are going to feel left out 😉
Oh how I want one of these with my coffee this morning!! Monster cookies are one if my all time favs!! Yum!!! Super Yum!!
That does sound like a perfect breakfast today!
