Halloween Cookie Bars are a soft, chewy cookie bar that incorporates a variety of candy and sprinkles. These bars are a fun way to get in the spooky spirit or use up leftover Halloween candy.

Halloween candy bars would be perfect to add to a Halloween-themed dessert bar of popcorn balls, Oreo spiders and any of these Halloween no-bake treats

Recipe FAQs

What candy should I use for Halloween Cookie Bars?

The options are endless for this cookie bar recipe. You can use any candy you have on hand. Some personal favorites include KitKats, Snickers, Reese’s and Twix bars.

Can I freeze these bars?

Yes! Candy freezes well and so do these bars. Make sure the bars are fully cooled before freezing them. I also recommend cutting the bars into squares and then freezing them in a single layer in an airtight container. 

How do I make these bars gluten free?

Use a one-to-one gluten-free flour blend (such as Bob’s Red Mill or King Arthur Baking Company) and be sure to check that all the Halloween candy you use is also gluten free.

Expert Tips

  • This batter is thinner than cookie dough so that it can be spread in the pan. 
  • Chocolate candy works best in these cookie bars but you certainly could try fruity candies if you would like. 
  • This is a great recipe to double and bake in a 9×13 inch pan. Be sure to increase the baking time to 35 minutes so your bars aren’t raw in the middle.

Instructions 

  • Preheat the oven to 350 degrees F and line a 9×9-inch baking dish with foil or parchment paper and grease well. 
  • In a medium mixing bowl, add the melted butter and brown sugar. Stir to combine. 
  • Add the egg and vanilla and beat very well until the mixture is light and puffy, about 2 minutes. 
  • Add the flour, baking soda, and salt, and stir to combine. The dough won’t be as thick as traditional cookie dough.
  • Chop the Halloween candy so that it's in bite-sized pieces, if needed. 
  • Add half of the Halloween candy and stir to combine. 
  • Press the dough evenly into the prepared pan.
  • Sprinkle the remaining Halloween candy on top of the cookie dough. Sprinkle the top of the dough with sprinkles if using.
  • Bake for 20-25 minutes or until golden brown and puffy. We bake them for 22 minutes on the dot every time and like that texture best. 
  • Remove from the oven and allow to cool slightly before cutting, or let them cool completely and then use the foil or parchment to help remove them from the pan before cutting. 

Notes

  • You can double this recipe and bake it in a 9×13 inch pan for around 35 minutes. 
  • Feel free to use whatever Halloween candy you have on hand. I tend to stick with chocolatey candy like candy bars, M&Ms, Milk Duds, and anything with peanut butter in it.
  • We don’t normally use fruit candy like Skittle or taffy, but you can sure try it if you like!
  • These bars would also be great to make with leftover Easter candy or Valentine’s candy.

    The nephews, 12 & 9 had a blast making this! We had a good laugh when the flour flew out of the mixing bowl. I didn’t line my pan…a mistake…..trying to shake it out of the cast iron skillet while still slightly warm created a mess…but a yummy mess….so we have random pieces instead of cute cut squares…but it is delicious! Oh…warning…whoppers turn into jaw breakers! Thanks for helping us make a fun memory!
