First, let me just say these candy cookies are life changing.

Who else always has a ton of leftover Halloween candy? If I don’t buy too much candy to hand out, then my kids bring home ridiculous amounts of candy that haunts us for weeks and sometimes months.

Dentists say it’s better to OD on candy over a few days rather than every day for weeks or months at a time. Therefore I’m actually doing you a favor. This is the perfect way to get that candy out of your house. You’re welcome.

Halloween Candy Cookies

So along the lines of using up all of our leftover candy fast, we’re making candy cookies. It’s the only natural thing to do. And I have to point out, as a self-proclaimed chocolate snob, I was completely shocked that I LOVED the way these tasted. I grabbed the core cookie recipe from my

Any who… Chop up the candy and throw it in the cookie dough. It’s that easy. The only special note for these candy cookies is that the caramel in some of the bars, with its high sugar content, will liquify and bleed out of your cookies making them a touch misshapen in spots. We can’t have that.

As soon as they get out of the oven, nudge them back into shape with the edge of your spatula. If that won’t work and they won’t nudge back, let the cookies cool and then gently tear off the abscess.

We actually had a decent rain storm this past week. I know. Shocking. It woke me up at 1 a.m. I couldn’t get back to sleep so I recipe tested these until 6 a.m. By noon I was ready for bed. But I wanted to write this up before I called it a day. Thank god for the weekend.

The Baker’s Guide to Measuring Flour

One of the biggest (and most common) mistakes in baking is how we measure flour. If you find yourself without a scale, see my top tips on how to properly measure flour for the perfect amount every time!

This cookies have some olive oil in them to keep them nice and soft! Try this other olive oil-based desserts: Salted Olive Oil Chocolate Chip Cookies or this Lemon Olive Oil Cake. Enjoy! xo

  • 1 1/2 cups (330 g)  brown sugar, packed (you can use dark, muscovado or light, your call)
  • 1/2 cup (100 g) granulated sugar
  • 8 tablespoons (113 g or 4 ounces) unsalted butter (room temperature)
  • 1/2 cup (100 g) extra virgin olive oil or sunflower seed oil 
  • 2 large eggs (room temperature)
  • 1 tablespoon (13 g) real vanilla extract
  • 2 cup ( 270 g) all-purpose flour (how to measure flour)
  • 1 cup ( 135 g) bread flour (how to measure flour)
  • 2 teaspoons  (10 g) baking powder
  • 1 teaspoon ( 5 g) baking soda
  • 1 teaspoon ( 6 g) sea salt
  • 2 1/2 cups (425 g) assorted Halloween candy bars, (chopped (peanut butter cups, Snickers, Three Musketeers, 100 Grand Bars, Twix…))
  • Sea salt flakes for the tops (optional)
  • *This cookie previously had White Whole Wheat Flour in place of the All-Purpose Flour — it’s delicious like that. Try it! xo


  • Preheat your oven to 350 F (177 C). Line a baking sheet with parchment paper or a silpat.
  • In an electric stand mixer fitted with the paddle attachment, cream your brown sugar, butter, oil and granulated sugar on medium speed until fully incorporated. Add the eggs + vanilla and mix on medium until everything is well blended.
  • In a medium bowl whisk together all-purpose flour (or white whole-wheat flour), bread flour, baking powder, baking soda and sea salt.
  • Dump the flour mixture into the electric stand mixer and mix on low until the cookie dough is barely blended. You still want to see streaks of flour. Take the bowl out of your stand mixer and fold in the Halloween candy until just mixed.  (Side Note: You can put the dough, wrapped tightly in plastic wrap, in the fridge for several days at this point, if you want to make the cookies another day. Additionally, you could also roll the dough into balls, freeze in a single layer on a cookie sheet and then shove them in a resealable plastic bag and put back in the freezer to have cookies on-demand…just add a minute or two to the bake time.)
  • Roll into balls of about 2 tablespoons each and allow about 2 inches of space between the dough balls.
  • Bake the cookies in the center of the oven for about 12 minutes. Fresh out of the oven, sprinkle with the sea salt flakes.  Allow to cool on the baking sheet for 5 minutes post baking and then move to a cooling rack to finish cooling down.
  • You’re done. They’re a revelation, am I right?

    I was wondering if you could do this with vegetable oil? And or butter or margarine?

    • Rebecca Firth January 27, 2024 at 8:10 AM

      Hi Aarora!
      Yes, you can absolutely use any cooking oil that you love in this recipe. You can also replace the oil with more butter (although that will change the texture of the cookie a bit). You can replace the 1/2 cup oil with 1/2 cup (113 g) of unsalted butter. Let me know if you have any other questions! xo

    I’m fairly certain all cookies are life changing, but these look particularly life changing ;). Leftover candy has never looked so good!

  • Karly October 31, 2016 at 11:27 PM

    Now these are what I call “Luxury Leftovers”! They look SO stinking good, and a perfect way to make better use of all that extra candy!

    Comfort food at it’s best♥

  • Geraldine | Green Valley Kitchen October 31, 2016 at 2:51 AM

    I always have tons of leftover Halloween candy since I live on a dark street – but I always buy a bunch on the off chance that a bunch of kids will show up. So now I know what I’m doing with the leftover candy – my office mates will thank you!

    • DisplacedHousewife October 31, 2016 at 1:33 PM

      Geraldine — We have the same situation!! I thought about all kinds of different things to make and decided that post Halloween, these would be the easiest + quickest!! I hope your office mates love them!! xox

  • Karen @ Seasonal Cravings October 30, 2016 at 9:10 PM

    OMG, I am so making these after tomorrow night. I have managed to keep all Halloween candy out of the house (bc I have no self control) – I hope there is some left for me to buy tomorrow. Butterfingers are my favorite so I’m filling my cookies with those. Yum!

    • DisplacedHousewife October 30, 2016 at 11:31 PM

      Karen — I hope you do!! I really thought it would just be a cookie stuffed with candy…but it’s so much more!! All those chopped up candy bars are transformative!! Let me know how they turn out with the Butterfingers!! ❤️❤️❤️

  • DisplacedHousewife October 30, 2016 at 3:46 PM

    Mary Ann — It’s so weird?!? I think the old name was better?? Those candy bars are cookie gold!!! Love love love what they did with the cookie!!! Happy Halloween to you too! I hope you and your family have a great one!! xoxo

  • Mary Ann | The Beach House Kitchen October 30, 2016 at 3:40 PM

    Yes, they were most definitely called $100,000 bars! It’s the only candy I would beg my kids for from their treat bags! Don’t know what’s up with the name change either Rebecca, but they sure as hell taste the same!! My willpower truly goes out the window when I see those! These cookies look like the perfect way to use up all that extra candy! Thanks for the recipe just in time for Halloween! Have a great week and Happy Halloween!
