Halloween Candy Cookie Bars are a fun and delicious way to use up leftover Halloween candy. These bars turn out different every time depending on what candy you add to the cookie dough.
Preheat the oven to 350 degrees F and line a 9x9-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 9x13 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.
