Step-by-Step Instructions
Here is how to make and bake these leftover halloween candy cookies. You can use a stand mixer or a large bowl with handheld electric mixer.
Step 1. Mix the Wet Ingredients: In a large mixing bowl, cream together the melted butter, brown sugar, and granulated sugar until light and fluffy, about 2-3 minutes. Add the egg and egg yolk followed by the vanilla extract, and beat until smooth.
Step 2. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking soda and salt.
Step 3. Form the Dough: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix. Gently fold in the chopped Halloween candy. Place the cookie in the refrigerator for 30 minutes to an hour.
When ready to bake preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Step 4.Scoop the Dough: Using a large cookie scoop or spoon, scoop the dough into 1.5-tablespoon-sized balls and place them about 2 inches apart on the prepared baking sheet. Top each of the cookie dough ball with extra candy pieces.
Step 5. Bake: Bake the cookies for 10-12 minutes, or until the edges are golden brown and the centers are still soft. Gently scoot the cookies using a large cookie cutter to get them into perfect rounds. The cookies will firm up as they cool.
Step 6. Cool: Let the cookies cool on the cookie sheet for 5 minutes before transferring them to a wire rack to cool completely.
Optionally sprinkle the top of the cookies with some flaky sea salt.

Tips & Tricks
- Candy Variety: Don't limit yourself to just chocolate! Try adding crushed candy corn, peanut butter cups, or even soft caramels for a fun twist.
- Don't use too much Halloween candy: Putting too much candy in the cookies will result in a bit of a mess, and you want to make sure that there is still a good ratio of cookie-to-candy. 1 cup is the perfect amount for me, but you could go up to 1 ½ cups at the maximum.
- Size Variation: If you like bigger cookies, you can use a larger cookie scoop, but be sure to adjust the baking time accordingly (add 1-2 minutes).
- Mix-in Options: You can also mix in chocolate chips, chopped nuts, or pretzels for an added crunch and variety of flavors.

FAQ's
You can use pretty much any of your favorite candies! You want to use candies that can melt well such as Kit Kats, Milky Way, Snickers, Reese's peanut butter cups, Heath Bars, Rolos, Almond Joys, any type of Hershey bars, M&M chocolate candies, candy corn, and Reese's pieces. I would avoid using any gummy candies as they won’t incorporate well in the dough.
Yes! Since this cookie recipe uses melted butter its essential to chill the dough to prevent the cookies from spreading too much during baking.
I haven't tested this recipe with gluten-free flour, but you can try using a 1:1 gluten-free baking flour blend.Be sure to check that your other ingredients, including the candy, are gluten-free as well.

- ½ teaspoon baking soda
- ¼ teaspoon salt
- 1 cup chopped halloween candy
- Flaky Sea Salt optional
Instructions
- In a large bowl, whisk together the melted butter, brown sugar and granulated sugar until smooth for 2-3 minutes.
- Add the egg, egg yolk and vanilla extract and whisk until well combined.
- Add in the flour, baking soda, and salt. Mix until just combined. Do not overmix.
- Gently fold in the chopped halloween candy, reserving a few for topping.
- Place the dough in the refrigerator and chill for 30 minutes. Preferably an hour.
- When you are ready to bake the cookies, Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
- Using a cookie scoop, portion the dough into 1.5-tablespoon-sized balls and place them on the prepared baking sheet about 2 inches apart.
- Press a few reserved candy chunks on top of each cookie. Bake for 10-12 minutes, or until the edges are golden and the centers look slightly underbaked.

Notes
- Chill the Dough: Chilling helps the butter firm up, keeping the cookies thick and chewy instead of flat. Even 30 minutes in the fridge makes a difference!
- Scoop Evenly: Use a cookie scoop for uniform cookies that bake evenly every time.
- Perfectly Round Cookies: Use a large round cookie cutter to gently scoot the cookies into perfect circles right after baking for that bakery-style finish.
- Don't Overbake: The cookies should look slightly soft in the center when you remove them from the oven - they'll continue to set as they cool.
- Bang the cookie sheet: Tap the baking sheet on the counter a few times as soon as they’re removed from the oven and before scooting. This helps the centers fall a bit before rounding them out.
