Equipment

  • stand mixer
  • Measuring cups and spoons
  • cookie scooper
  • Knife
  • Cutting Board
  • Baking sheet
  • parchment paper

Ingredients

  • 1/2 cup unsalted butter cold and cubed
  • 1/2 cup brown sugar
  • 1/4 cup cane sugar
  • 1 tsp vanilla extract
  • 1 egg
  • 1 tsp cornstarch
  • 1/2 tsp baking soda
  • 1/2 tsp of salt
  • 2 cups all purpose flour
  • 2 cups leftover Halloween candy chopped, divided

Instructions

  • Preheat the oven to 400°F and line baking sheet with parchment paper.
  • Use a stand mixer and with a paddle attachment and cream together butter and sugars on low speed until light and fluffy, approximately 4 minutes.
  • Add the egg, vanilla extract, salt, baking soda, and cornstarch. Mix until smooth; making sure to scrape down the sides of the bowl as necessary.
  • Turn the mixer to low and gradually add the flour in with the wet ingredients, mixing until combined.
  • On a cutting board, finely chop the leftover halloween candy. Then, use a rubber spatula to fold 1 1/2 cup of the mix-ins.
  • Using a 1.5 tbsp cookie scoop (medium sized), and portion the cookie dough balls onto your baking sheet into ~12 even cookies. Gently press the remaining 1/2 cup candy pieces into the top of each cookie before baking.
  • Bake ON THE BOTTOM/MIDDLE RACK cookies 8-10 minutes or until the edges are golden brown and middles have begun to set. Note: middles may look slightly underdone. They will continue to bake as they cool.
  • Optional: Add a pinch of flaky salt to the top of each cookie and let cool for 10 minutes. Then transfer to a wire rack. Enjoy!

Notes

This recipe was originally published in October 2021. Click HERE for the original recipe. 
Do not bake on the top rack as the cookies can harden/burn before baking.
Although these Halloween Candy Cookies are meant to be “throw in whatever you’ve got”, I do advise against sour or fruit candies like Jolly Ranchers, Starbursts, Skittles, Swedish Fish, gummy bears, etc.
