Instructions for Making Chewy Monster Cookies
- Preheat oven to 350° F and line a cookie sheet with parchment paper.
- Combine softened butter, peanut butter, granulated sugar, brown sugar, vanilla, and eggs in a mixing bowl and beat until creamy. I use my stand mixer for this to cream the ingredients together easily.
- Slowly add the old fashioned oats and baking soda to the wet ingredients and beat until combined.
- Beat in the chocolate chips and M&M's on low speed, scraping down the sides of the bowl, and evenly distributing the candies in the cookie dough.
- Scoop cookies by 1 and a half tablespoons or use a #40 cookie scoop to portion into cookie dough balls and place them onto the prepared cookie sheets two inches apart.
- Bake for 11 to 13 minutes, let them cool for 5 minutes before transferring them to a cooling rack to cool completely.
For chewy cookies, bake until the edges are browned but the centers are still soft. The cookies will continue to bake as they cool.
Variations in Monster Cookies
This recipe for monster cookies uses old-fashioned oats but quick oats can be used instead. It will alter the chewiness of the cookies but will still taste delicious.
Creamy peanut butter is used in this recipe but chunky peanut butter can be used in its place if you prefer a crunchier cookie.
To make this cookie peanut butter free, a different nut butter such as almond butter or seed butter can be used with great results.
Tools Needed to Make Monster Cookies
Having the right kitchen tools on hand helps make the baking process go faster. Here are some suggested cookie baking tools.
- A stand mixer with a paddle attachment or an electric mixer, to combine the ingredients easily.
- Baking sheet
- Parchment paper
- A measuring cup and spoon set to measure the ingredients correctly.
- A very large mixing bowl and medium bowl for the wet and dry ingredients.
- A #40 cookie scoop for portioning the balls of dough.
- A rubber spatula for mixing and scraping down the bowl.
- Cooling rack to let your cookies cool before storing.
Storing Monster Cookies
When it comes to storing your monster cookies, there are a few crucial steps to ensure that your delicious dessert stays fresh and chewy. Proper storage helps your cookies stay in great condition, keep flavor, and keep them fresh when preparing them in advance for gift giving for Christmas or just to eat at a later date.
The first step is to make sure that your fresh-baked cookies have completely cooled down after baking. Placing warm cookies in an airtight container can cause condensation, making them soggy.
Place the cookies on a wire rack to cool them completely before storing them.
Also, before stacking the cookies, make sure the chocolate chips have had the chance to harden to prevent the chips from melting and making the cookies stick together.
Once the cookies are cooled, place them in an airtight container. This is a great way to keep your cookies fresh short term. They will stay fresh for up to five days.
When baking cookies for Halloween or Christmas ahead of time, allow them to cool completely before transferring them to a freezer safe bag in a single layer and freeze for up to 3 months. Label the freezer bag to take the guesswork out of when the cookies were made. For extra protection, place the freezer bag in a freezer safe container. This locks in freshness for the cookies and they will taste great!
Top Tips
Use room temperature ingredients to easily cream the butter and sugars together easily.
Avoid overbaking these monster cookies to get the best monster cookies with the chewiest texture. Allow the cookies to brown on the edges but they should still have a chewy center when taking them out of the oven.

So happy to hear that you guys enjoyed them! Love that your daughter is into baking right now! <3
Can you tell me which type of oatmeal works the best for these?
I used old-fashioned vs. quick oats because the cookies have more texture with the old-fashioned. How that helps!
Yes thanks!!!!!
My cookies are coming out completely flat. Is that normal? I'm frustrated cause I followed all the steps and idk when I could have gone wrong
Your butter may be a little too soft. You can chill the dough for about half an hour to prevent the cookies from spreading in the oven.
For some reason the cookies do not seem like they are done within the time frame it says which results in the bottom coming out a little burnt. Help.
Hi Isabella,
The cookies should be soft in the middle. They still continue to bake once they are taken out of the oven.
Our neighbor, Kristin, sent these delicious cookies over earlier this month. She knows I like to freeze dough, and bake later. Kristen put dough balls in a ziploc freezer bag with a note on the bag of what to. I just baked these this morning, and they are delicious! I'm adding them to my baking recipes and sharing your site on my facebook page. Thank you for sharing these!

Hi Kathy! I am so happy to hear that you enjoyed these cookies!
Amazing cookies!! I used chocolate chips and butterscotch chips instead of M&Ms, and only used about 1/2 bag of each and they turned out perfect. The dough seemed wet but the cookies didn’t spread too much, 13 minutes cook time was perfect. Once I took the cookies out of the oven and they cooled a little the middle looked a little wet, but they were cooked to perfection. Highly recommend!

Hey Jackie! Yup, they're supposed to look underbaked in the center... that's how you get that incredibly soft and chewy cookie! I'm so happy to hear that you enjoyed them!
Can you freeze the dough? If so does it change the taste? Also, should I thaw them before baking or bake the frozen?
Yes, you can! I'd recommend scooping the dough and then freezing the dough balls in an airtight container. If stored properly the taste should not change. No need to thaw the dough first, just keep an eye on the cookies at the end of the baking time. 🙂
Can you use less sugar ?
Yes, you can use reduce the amount of sugar in this recipe but it may alter the chewiness of the cookies, especially the brown sugar. 🙂
