Welcome to the first day of Chocolate Chip Cookie week!!

Chocolate Chip Cookie Week at

Since everybody loves chocolate chip cookies, all this week I’m going to be featuring various recipes revolved around chocolate chip cookies! Stay tuned for a fun surprise at the end. To kick things off, we’re starting with Monster Cookie Bars, loaded with much more than chocolate chips. These babies were created for Imperial Sugar and are filled with Halloween candy!

What were your best Halloween costumes growing up? Or even now as an adult? I’ve been Cinderella, a Power Ranger, a witch (1 and 2), a pop star (it was either Britney Spears or Christina Aguilera, I can’t remember), and a devil, just to name a few. Dressing up is fun, but usually only for the first half hour or so. Then it’s uncomfortable and all you want is the Halloween candy.

This recipe is the perfect way to use up any extra or leftover Halloween candy. Any kind of m&m will work wonderfully in these Monster Cookie Bars, along with any chopped chocolate candy. Actually, you can pretty much fill these bars with whatever candy you want or have and they will be positively scrumptious.

Recipe Rundown
Taste: I adore the combination of oatmeal, peanut butter, brown sugar, and chocolate candy because the nuttiness balances out the sweetness.
Texture: Thick, chewy, with bites of crunchy, gooey, and soft chocolate candies throughout. I used a lot of Halloween fun-sized Snickers candies and it was delish.
Ease: Very easy. Be sure that when you’re melting the butter and brown sugar that you keep an eye on it and don’t walk away.
Appearance: How fun do these look with the bright and colorful m&ms studded throughout?
Pros: Fun and even more delicious way to use up leftover Halloween candy.
Cons: None.
Would I make this again? Absolutely!! I love Monster cookies, especially in the form of bars with extra candy added in.

    Thanks for the recipe! I used to make monster cookies for my kids all the time. This is a quicker way to make a batch for the office crew. Yummy!
