Pin ItMonster Cookies are one of my all-time favorite cookies (I also love monster cookie bars and monster cookie energy balls). The classic monster cookies are packed with peanut butter, oats, chocolate chips, and M&M’s. So much goodness in one cookie.
Well, I decided to take the classic and add cocoa to the mix to create a Chocolate Monster Cookie and this cookie is INCREDIBLE! Definitely a new favorite!
These cookies remind me of No Bake Cookies in flavor because they have chocolate, peanut butter, and oats. But the cookies are baked, soft, and chewy. Like traditional monster cookies, they also have chocolate chips and colorful M&M’s. They are SO fun and SO delicious.
If you are a chocolate peanut butter fan, you will LOVE these cookies. And they are really fun for Halloween. I like to add candy eyeballs to make them a little spooky! Kids and adults love them!
Table of Contents
Ingredients
- All-purpose flour– spoon and leveled. Never pack your flour when measuring!
- Cocoa powder– use unsweetened cocoa powder to give the cookies a nice chocolate base!
- Baking soda– make sure it is fresh.
- Salt– I use kosher salt.
- Unsalted butter– at room temperature. Make sure it isn’t too warm or your cookies will spread.
- Sugar– granulated sugar and brown sugar.
- Peanut butter– I prefer creamy peanut butter, but crunchy will work too. I prefer a brand like Skippy or Jif for baking.
- Eggs– always use large eggs for baking.
- Vanilla extract– always use pure vanilla extract.
- Oats– use old fashioned oats instead of quick oats.
- Chocolate chips– I prefer semi-sweet chocolate chips, but milk or dark will work too.
- M&M’s– so colorful and fun!
- Flaky sea salt– for sprinkling on cookies!

These cookies was a HUGE hit with not only my family but with a friend’s family as well. Thank you so much.
You are welcome! I am so glad you loved them!
I love all your recipes; even have both of your cookbooks. Quick question: can I use an alternative butter like almond butter? I canโt have peanut butter anymore.
Thank you! I haven’t tried this recipe with almond butter, but it should be fine, just a different flavor.
