Candy Cookie Bars

Are you staring at your dining room table littered with colorful wrappers of candy, candy, candy! Before you throw it all away, transform your leftover chocolate candy into the world’s sweetest cookie!

Whether you are trying to get rid of excess candy you purchased for Trick or Treaters, or trying to minimize your child’s loot bag, Candy Cookie Bars are the tastiest and easiest way to reduce your candy supply before it goes to waste.

These cookie bars are basically the Halloween kitchen sink of cookies. It doesn’t matter what chocolate candy you throw into the batter, it will always taste good. Imagine the ooey gooey-ness of Snickers caramel, the creaminess of Reese’s Peanut Butter and the crunch from M&M’s. Each bite is a taste of your favorite candy bar surrounded by a soft cookie shell.

For this recipe I used KitKat bars, Reese’s Peanut Butter Cups, Snickers and M&M’s. Simply chop all chocolate candies and stir into the batter. I’ve learned if you are using 3 or more types of candy, you should use a rectangular or square baking dish to create a cookie bar rather than traditional cookies.

If you’re still staring at mountains of Halloween candy after baking these cookies, donate your candy supply to soldiers overseas!
