A Quick Look At The Recipe

  • Recipe Name: Big, Chewy Crumbl-Style Halloween Candy Cookies
  • Serves: 8 Large Bakery-style Cookies
  • Main Ingredients: unsalted butter, softened, light brown sugar, granulated sugar, egg, vanilla extract, all-purpose flour, baking soda, baking powder
  • Why You'll Love It: These Halloween Candy Cookies are the perfect way to turn that mountain of leftover candy into something even better. They’re fun, festive, and just the right balance of chewy, chocolatey, and over-the-top. Happy baking, y’all!

Every bite is a little different, with peanut butter from a Reese’s in one spot and caramel from a Snickers or a crunch of Kit Kat in the next, so toss in whatever mix your family left in the bowl. If you’d rather stick with one candy, my old-fashioned M&M cookies are a classic, and either one is awfully good with a mug of stovetop hot chocolate on a chilly fall night.

Why These Halloween Candy Cookies Bake Up Thick and Chewy

The dough uses three times as much brown sugar as white sugar, which keeps the centers soft and chewy, and a little baking soda plus baking powder gives the cookies lift so they rise tall instead of spreading thin. Shaping the dough into half-cup portions and pressing them into thick disks gives you that bakery look, and letting them finish setting on the warm pan keeps the middles gooey.

Ingredients for Halloween Candy Cookies

Labeled ingredients for Halloween candy cookies: butter, brown sugar, sugar, egg, vanilla, flour, baking soda, baking powder, salt and chopped candy bars

Leftover Halloween candy: Snickers, Twix, Kit Kats, Reese’s cups and M&M’s all work. Chop the bars into bite-size chunks so every cookie gets a few different kinds.

Unsalted butter: Let it soften at room temperature so it creams up light and fluffy with the sugars. Melty butter makes the cookies spread.

Light brown sugar: It does most of the sweetening here and is the secret to the chewy texture.

Helpful Tips Before You Start

  • Line your baking sheets with parchment paper so the bottoms don’t over-brown and the cookies slide right off.
  • Freeze softer candy like Reese’s cups or Milky Ways for about 10 minutes before chopping so it doesn’t turn into a sticky mess.
  • Save a handful of chopped candy to press on top of the warm cookies for that bakery-case look.
  • For smaller cookies, use a medium cookie scoop and take a few minutes off the bake time.

Halloween Candy Cookies FAQs

What candy works best in these cookies?

Chocolate bars with caramel, peanut butter or crispy wafers hold up best in the oven, like Snickers, Reese’s cups, Twix, Kit Kats and M&M’s. Hard candies and gummies don’t melt the same way, so leave those in the treat bowl.

How can I make them even chewier?

Add an extra egg yolk to the dough along with the whole egg. It makes the cookies richer and a little chewier in the middle.

Yes. Press the dough into a parchment-lined 9×13 pan and bake at 350°F for about 25 to 28 minutes, until the edges are set and the center is still a little soft.
