Monster cookies without flour are packed full of any kind of leftover candy available. With all of the goodness of traditional monster cookies, these use whatever candy you have sitting around your house after the holidays.

Monster Cookies Without Flour Recipe

Halloween, Christmas or Easter have come and gone, and now there’s all that pesky candy sitting around.

The age old question after any holiday is what in the world are we going to do with all this leftover candy?

Sometimes we chop it up and toss it in Grandma’s Homemade Brownies. Or, we’ve been known to make a batch of Gooey Butter Bars filled with leftover candy too. This year after a haul at Mickey’s Not So Scary Halloween Party, we decided to use up the leftover candy in this cookie recipe.

Barbara’s kids love these Thick Candy Monster Cookies. It could be the monstrous size or the combination or peanut butter, oats and candy. Want a cookie using Reese’s Pieces? Check out these Giant Peanut Butter Cookies with Reese’s Pieces.

She always knows these will be a hit in our family, and the only thing that makes them better is a big glass of milk! If you aren’t a fan of peanut butter, try these M&M Oatmeal Cookies to use up those extra holiday M&Ms.

Notes about No Flour Monster Cookies

We use quick cooking oats for this recipe. In a pinch, old fashioned oats could be used. You can even give them a quick buzz in the food processor to make them more like a quick oat.
These make a thick monster cookie, more like a bakery-style monster cookie.
Chocolate chips or a combination of chocolate chips and candy can be used.
Use creamy or crunchy peanut butter.
Barbara used a combination of Twix, Milky Ways, Dove Chocolates and M&Ms. You could use any chocolate-based candy you have on hand.
If you use a caramel centered candy, be sure the candy pieces are not peaking out of the dough before baking. If it is, you risk caramel spilling out and hardening.
Remove these from the pan after a few minutes of cooling to prevent them from sticking.

Why are they called monster cookies?

Here’s our theory on the background of the monster cookie. Monster cookies are huge! They legit are double the size or a typical cookie. Think of a monster cookie as a thick, bakery-style cookie, monstrous in size.

What can I do with leftover candy from Halloween?

First off, the shelf-life of candy is anywhere from six to nine months, so there’s no need to eat it all at once. Another good option is to freeze part of it for later. Depending on the type of candy, you can expect to gain anywhere from another six months to a year by freezing candy.

We, personally, like to use a bunch of it at once in other dessert recipes such as Grandma’s Homemade Brownies where we stir in the chopped up candy, or in these tasty Gooey Butter Bars featuring leftover candy.
