If you’re wondering how to use up that bowl of candy sitting on your counter, these leftover Halloween candy cookie bars are the way to go! They’re perfectly soft, chewy, and loaded up with your favorite candies. Whether you throw them on top or mix them in, you can’t go wrong with these delicious cookie bars.

What to do with leftover halloween candy

Take those fun-sized candies to the next level with these cookie bars. They’re chopped up and baked inside these dense and chewy bars which for some, that’s enough, but I needed to take it a step further!

After they’re baked, these cookie bars are piled with even more candy. It’s so fun to fit the different shapes and sizes together to completely cover the surface of these bars.

To prevent these bars from being TOO rich (although I cant’ lie…these are not for the faint of sweet tooth), a hefty pinch of flaky sea salt is added on top. Which now I think I need to add flaky salt to every individual candy I eat from here on out.

What kind of candy works best in leftover halloween candy cookie bars?

Any variety of chocolate candies will work in this recipe. This includes M&M’s, Hershey’s, Kit-Kat, Snickers, Twix, Butterfinger, Reese’s, Milkway…the list goes on.

Stay away from any sugar-based candies like gummies or candy corn. They’ll completely melt into puddles in these bars…plus they probably just won’t taste that great in this recipe.

Are the cookie bars too sweet with all that candy?

You might be thinking that all this candy could lead to a super sweet and rich cookie bar. BUT this recipe is specifically made to withstand all that extra sugar.

First, these Halloween cookie bars are made with a little extra salt. That doesn’t mean these cookie bars are salty, it just helps to balance out all the candy.

Then even more salt is sprinkled on top after the extra candy decorations are added. For regular cookie bars this would be total salt overkill, but for these super rich Halloween candy cookie bars it’s just the right amount.

The cookie bars also use a bit less sugar overall. Only 3/4 cup is added to the dough which is just enough to create a soft and chewy texture, but not too much to where each bite gives you a cavity.

How to prep your halloween candy for baking

Candy is used in two different ways for these candy bars:

1. Inside – Candy is chopped up and mixed in to the dough before baking. It’s important to chop tiny bite-sized chunks so there’s an even distribution throughout. This can also be a mix of any candy you like!
2. On Top – The loads of Halloween candy on top is frozen before it’s placed. This is to prevent the candy from instantly melting since they’re placed on top of the piping hot bars.

The bars are baked with an even sprinkle of chocolate chips on top. Once baked, those chocolate chips melt and act as the glue to hold the candy on top.

Candy on top of these bars can be kept whole, roughly chopped, sliced in half…it’s really your own creative process for this final step. Just have fun and make sure ever inch of the surface is covered!

How to store your halloween candy cookie bars

These cookie bars are best enjoyed at room temperature, but can to be stored in a container in the refrigerator or at room temperature.

They will keep longer in the refrigerator (about 4-5 days), but will remain just as good at room temperature (about 2-3 days).

Can this recipe be made gluten free?

I haven’t tested it, but I think this recipe could work well with a gluten free baking flour substitution. Also make sure to use gluten free candies!
