How to Make Monster Cookies

Monster Cookies are so easy to make that even children can make them with a little supervision. All you really need is a big bowl and a wooden spoon and a lot of elbow grease. A stand mixer makes it a lot easier though as the dough can get a little a little tough to stir. But if you’re looking for a good arm workout, or if you want to tire out the kids, go for the bowl and spoon!

The secret to making sure the cookies are perfectly chewy is to take them out of the oven a few minutes early, and then to let them cool for about 5-10 on the cookie sheet before transferring them to a cooling rack. Just look for the edges of the cookie to be slightly golden. You’ll want the center to look just set or even slightly under. Remember that the cookies will continue to bake slightly even after taking them out of the oven.

Monster Cookie Variations

Feel free to change up some of the ingredients if you’d like. For instance, you could use almond butter or cashew butter instead of peanut butter. I think they’d be great with almond butter, cinnamon, and raisins. Or you could use Nutella for a chocolatey version. How about using butterscotch chips? I think a Christmas version with cranberries and pecans sounds lovely! If you find a great combination, I’d love to hear about it!
