Halloween is just around the corner, so I think it’s only fitting we bake up a batch of Monster Cookies.
Okay, fine, there is nothing festive about these cookies, except for the name.
Why are they called Monster Cookies?
Well, apparently they are called MONSTER COOKIES because they are the “frankenstein” of cookies, a complete mashup! There is great debate though about what you MUST include in order to consider them a Monster Cookie.
Frankly, I think any mashup qualifies, but others would disagree.
For today’s recipe, I started with a peanut butter oatmeal cookie dough. I added in M&M’S and chocolate chips. Personally, I would have loved to add raisins, but my kids would then develop trust issues and never touch a cookie again.
If you do like raisins in your cookies, add a cup of them into the dough! Or bake up a batch of these perfect Oatmeal Raisin Cookies instead!
How do you make Monster Cookies?
First, start by preheating your oven to 350 degrees F. Line a baking sheet with parchment paper. Set aside.
Using a large mixing bowl, combine your butter with brown sugar and granulated sugar. Cream this together until smooth. Add in peanut butter, eggs, vanilla extract (the real stuff), and blend well.
Add in your flour, quick cook oatmeal, and baking soda. Combine completely. Fold in chocolate chips and M&M’S. Feel free to use holiday colored candies, or any flavor of M&M’S are delicious too, try the pretzel or caramel for a yummy twist!
Use a 2 Tbsp scoop and bake cookies for about 12-15 minutes. You’ll get around 55-60 cookies. These freeze really well too. You can freeze the dough balls (place uncooked cookie dough balls on baking sheet in freezer for one hour, then transfer them to a ziploc bag in the freezer until ready to bake). Or freeze the cookies after baking by placing in an airtight container. ENJOY!
