Chocolate Monster Cookies

Chocolate Monster Cookies are sweet, chocolate cookies packed with so many good things! - Bake or Break

It seems like everyone has a recipe for a huge, decadent cookie, known usually as Monster Cookies. I’ve certainly made them before. I don’t think I’ve ever seen any with a chocolate cookie. I also started thinking that I don’t bake nearly enough with cashews. So, that’s how I ended up with these cookies.

And they are fabulous. The flavor and texture of them reminds me a lot of those chocolate no-bake cookies that most of us are familiar with. You know the ones with the peanut butter, chocolate, and oats that are made in a saucepan. I made a similar cookie using Nutella earlier this year.

As with most “monster” cookies, these are jam-packed with flavors. Chocolate, peanut butter, and cashews supply plenty of crunch, while the oats add the chewiness of an oatmeal cookie.

  1. These cookies may be my favorites from Jennifer this Christmas Season! They are truly “monster” cookies in that they are a full dessert (or breakfast in my case) in just one cookie. There is a ton of flavor in them, and they are so, so good!

  2. Most monster cookies don’t appeal to me but these do. I like that they’re nice and oaty! Plus with chocolate and peanut butter, you’ve totally got me:)

  3. Just today, I was thinking how some kind of oatmeal cookie would taste good & I stop by your blog & see your recipe! Not crazy about peanut butter chips so will try another mix-in 🙂

  4. cookies look wondefrulllll and deleciousssss

  5. Julie, they truly are delicious!

    JEP, I must be reading your mind! You could definitely use something besides peanut butter chips. Maybe white chocolate or caramel or butterscotch or cinnamon. That’s the beauty of monster cookies. Pretty much anything goes.

    Thanks, sagari!

  6. My sister came back from a trip to the North East region of Brazil and, among other things, she brought a bag of cashew nuts. I think I have just found out what to do with them. 🙂

  7. Oh, YUM! Chocolate, peanut butter and cashews?? Delicious!

  8. Patricia, I hope you enjoy them!

    Dana, I couldn’t agree more!

  9. I love monsters! I love chocolate!

    Will make soon.

  10. Thanks, Marcia!

    Anna, I hope you enjoy them!

  11. I want to try these! Do you use old-fashioned or quick oats, or does it matter?

  12. Pam, either kind of oats should work. I usually use old-fashioned unless the quick kind are specified. Enjoy!

  13. These were a big hit! Although I suppose mine weren’t “technically” monster cookies…reduced cooking time/made them smaller… they were gone in a flash. Neighbors requested more! Thank you, enjoy your recipes!
