Why You’ll Love This Recipe
Monster Cookies are one of those classic cookie recipes, one that I’ve been making for years and years. They are the perfect combination of peanut butter cookies and oatmeal cookies with the bonus of chocolate chips and M & M’s!
These cookies are also a great choice if you are looking for a flourless cookie. Make sure to use gluten free oats if you want to make the cookie truly gluten free.

How to Make Monster Cookies
- Preheat oven to 350 degrees F. Line baking sheets with parchment.
- In the bowl of a stand mixer with the paddle attachment, cream together the sugar, brown sugar, corn syrup and butter until light and fluffy.
- Beat in the eggs, one at a time, and then beat in the peanut butter, vanilla, baking soda and salt until well combined.
- Add the the oats and mix until combined, then add the chocolate chips.
- Scoop dough onto the prepared baking sheets, spacing the mounds at least 2 inches apart. I use a 1/4 cup scoop. (I made the ones in the photo a bit smaller as I needed to get more cookies.)
- Bake the cookies for 12-15 minutes then remove them from the oven.
- Press M & M’s into the cookies while they are still warm.
- Allow them to cool for 5 minutes on the baking sheets before transferring them to a rack to cool completely.
Monster Cookie Tips
- I prefer creamy peanut butter but you can use crunchy too to add in more texture.
- Using old fashioned oats will give you a chewier texture to the cookies.
- Having your ingredients at room temperature will help them to combine better.

These cookies sold fast!!!!! Thank you so much. And the basket was a perfect touch too. In fact near the end of the bake sale we loaded the basket up with all kinds of goodies and one great friend of Kevin’s carried it around selling and emptied it out 2 times! The bake sale was a great success thanks to wonderful friends that donated baked goods. Thank you so much.

Thanks for the recipes! You seem to just keep sending me the right things! I’m still in search of the perfect sugar cookie. I haven’t found it yet but I will try the one from Real Mom Kitchen. I have a question…do you really read all of our responses?

YUM! My 4 year old has been begging me to make cookies! I’m off to the store to get the ingredients!

Leigh Anne, I jumped online to post about your corn and blueberry salad but I had to comment on this first. I made Monster Cookies for the children in our primary after their hard work for the years that I was in Primary. I thought that it was funny you did too.
Anyway….I tried the corn and blueberry salad out on the ladies from church. I was a little skeptical but I kept the faith because I have NEVER had a bad recipe from you. What I really liked about it was how fresh it tasted with the fresh corn! Thumbs up. {some of the ladies thought that it was a black bean and corn salad so you can imagine their surprise when they bit into a BLUEBERRY!}

Yum. My kids will love these.
I found two blog entries that I think you will love. Pretty and delicious. By the way, we had your Logan as a counselor this year. You raised an amazing young man. Hundreds of kids were blessed by knowing him.
