Halloween is easily my favorite holiday.  I love all the spooky fun, excessive amounts of pumpkin bread, going all out on a costume, and it goes without saying, that I LOVE the candy. And Halloween is the one time of the year where it is perfectly acceptable to pound mini kit kats with no judgment. Orrrr you can chop up all that candy and mix it into a chewy, buttery, delicious halloween candy cookie bar.

Use up all that leftover candy with these quick and easy leftover halloween candy cookie bars

You know those little jack-o-lantern candy buckets that kids carry around on Halloween? Well growing up, my house had one of those year round AKA “the candy bucket.” To this day, it has a never ending supply of candy in it and is magically replenished whenever it’s running low.

I can still picture the frisbee eyes on my elementary school friends when they came over to my house for the first time and discovered the candy land we lived in compared to their sugar free homes.

These leftover halloween candy cookie bars come together in one bowl and are a crowd pleaser for grownups and kids alike this Halloween season

The weird thing about having candy around us constantly was that it meant we didn’t feel the need to binge on it, because it was always available. So, while other kids were scarfing down all their candy on October 31st,  I’d have two or three pieces and dump the rest in the candy bucket for a later date. Like breakfast tomorrow maybe 🙂

It also meant we always had a lot of leftover candy. And sometime my mom would want to use all that candy up to free up some space for more candy. Thus halloween candy cookie bars were formed.

What kind of candy should you use for Halloween Candy Cookie Bars?

Any kind of candy ! This recipe is super adaptable so really whatever you have on hand will do! We had a variety bag of Halloween candy for all the neighborhood kiddos so we used Twix, Snickers, Kit Kats, M and M’s, Reeses, and a handful of candy corn. Simply unwrap all your leftover candy, chop into bite size pieces and fold into your blondie batter!

Tips for making the best cookie bars:

  • DO NOT OVER MIX YOUR BATTER: Just don’t do it, okay? When you over mix your dough, you build up more gluten which leaves you with a dry, and tough cookie bar. Not what you want, right?
  • Use a variety of candy: It’s fun to use all different kinds of chocolate bars for variety and different textures!
  • Don’t over bake: You’ll want to take these out when they’re still gooey in the center to prevent drying out!

Follow these tricks and you will have the best halloween candy cookie bars ever.

We hope you enjoy your sugar rush 🙂

Love this recipe! I plan to make it this week. I noticed you have an option to double or triple this recipe. My question is, what size pan would I use if I doubled the recipe and how long would I cook it. Thanks so very much!

Sofi | Broma Bakery

Hey Debbie! I would bake the double recipe in a 9 x 9 pan and a triple in a 9 x 13! Enjoy!

Jennifer Brown

Did you make this and triple it? How long did you bake it for?

Kirsten Cavnar

What a great idea! Can’t wait to try!!

You’ll love them! Can’t wait to hear what you think!


Can I respectfully request that it would be helpful if your recipes-especially those that involve baking- could also list ingredients by weight? Thanks.

Sofi | Broma Bakery

Hey Ann! We don’t bake with a scale generally but it’s definitely something we’ll consider if we get the feedback for it!


I made this yesterday. Definitely a hit with my family. I got a box with many different candy bars on sale at Costco, so I am ready to make these again at a moments notice. Very easy to mix and get in the oven.

What a great idea! Happy to hear you and the family enjoyed these!
