Who else is excited for Halloween? We love this time of year, when the weather gets a little bit colder, pumpkins decorate everyone’s doorstep… and it’s socially acceptable to eat way too much candy. But isn’t it funny that no matter how much chocolate you manage to scarf down throughout the month of October, there’s somehow always a bunch of leftover Halloween candy come November?

If your Halloween is anything like ours (i.e. you bought a ton of candy and no trick-or-treaters showed up to your house), you might be left wondering what to do with all these leftover sweets! Look no further, because we have the perfect idea for you: turn them into Halloween candy cookies.

Chocolate chip cookies are our favorite dessert, so it seemed like a no-brainer to mix chopped up pieces of chocolate candy into cookie dough. Halloween candy cookies give you a unique way to continue eating all that leftover candy throughout the holiday season, after you’ve gotten sick of eating individually wrapped fun size chocolate bars for a month straight. The best part is, you can stick these cookies right in the freezer and enjoy them over the course of a few months!

Whether you’ve got Kit Kats, 3 Musketeers, M&M’s, Milky Way bars, Reese’s cups or any other chocolate candy, this leftover Halloween candy cookie recipe is the perfect way to use it all up. Get the whole family together on November 1st and make a batch for yourselves, or host a post-Halloween party and give them out to your friends. They’ll thank you for the delicious treat and the great idea for what to do with their own leftover Halloween candy!

Halloween Candy Cookies Recipe Ideas

We’re sharing 6 variations on this cookie recipe, made with our favorite leftover Halloween candy, that we hope will inspire you to invent your own delicious candy cookie concoction! Each cookie type uses either vanilla or chocolate dough as the base, chosen to complement the flavor profile of each type of candy. And just to make things extra sweet, we mixed in a few extra elements – chocolate chips, white chocolate chips, caramels – but these are totally optional.

It’s impossible to make a bad cookie when it involves Halloween candy… as long as it’s chocolate-based. (We wouldn’t recommend trying gummy worms or lollipops in your cookies). So we urge you to mix and match all your leftover Halloween chocolate candies however you like, using our cookie recipe as a guideline to get you started. No matter what combination you create, we promise it’ll be delicious!

6 Ideas For Using Leftover Halloween Candy In Cookies

To inspire your leftover Halloween candy cookies, here are 6 delicious flavors we made using our vanilla and chocolate cookie dough base recipes:

  1. 3 Musketeers Cookies – Vanilla cookie dough, chopped 3 Musketeers candy bits
  2. Kit Kat Chocolate Chip Cookies – Chocolate cookie dough, chopped Kit Kat candy bits, white chocolate chips
  3. Vanilla Milky Way Cookies – Vanilla cookie dough, chopped Milky Way candy bits, baking caramels
  4. Chocolate Milky Way Cookies – Chocolate cookie dough, chopped Milky Way candy bits, baking caramels
  5. M&M Chocolate Chip Cookies – Vanilla cookie dough, M&M’s, white chocolate chips
  6. Reese’s Peanut Butter Cup Cookies – Vanilla cookie dough, peanut butter, chopped Reese’s peanut butter cups, milk chocolate chips

Our vanilla cookie dough is simply the base recipe we use when making traditional chocolate chip cookies. The chocolate cookie dough is a modification of the vanilla dough that replaces some of the flour with cocoa powder for a rich chocolate flavor. Both dough recipes are perfectly chewy, soft, and oh-so gooey when they’re hot out of the oven!

Mix and match your leftover Halloween candy with either flavor of cookie dough to make whatever combinations your heart desires. With these two delicious cookie dough recipes as your base, you really can’t go wrong!

How To Make The Best Halloween Candy Cookies

To really take your leftover Halloween candy cookies up a notch, you can mix in additional flavors! Here are two different techniques we used to flavor our Milky Way cookies and our Reese’s peanut butter cup cookies:

  1. Stuffed caramel centers: For the two Milky Way cookies, you can easily add an extra burst of warm, gooey caramel at the center of the cookie. After folding the chopped candy into the dough, roll out the cookie dough balls as usual, then flatten them between your palms. Place a baking caramel in the center of each disk, then mold the dough around it and shape it back into a ball.
  2. Peanut butter flavor: Add a scoop of peanut butter to the vanilla cookie dough base for a hint of peanut butter flavor in your Reese’s cup cookies. You can either make the vanilla dough as-is, then stir in the peanut butter before folding in the chopped Reese’s cups and chocolate chips. Or, you can mix the peanut butter into the wet ingredients when making the vanilla dough.

As for the rest of our Halloween candy cookie creations (say that 10 times fast), we simply folded candy bits into the dough and called it a day. It’s that easy to make delicious leftover Halloween candy cookies! My favorite were the 3 Musketeers cookies, and Alex loved the Kit Kat cookies. No surprise, since these are our favorite candy bars.

What leftover Halloween candy will you mix into your cookies?

We had so much fun creating different combinations of Halloween candy cookies. If you’re looking for an activity to do with friends or family this time of year, bake a batch of these cookies together with your leftover Halloween candy! They make a delicious themed treat for parties or potlucks, so it’s a win-win.

This recipe is the perfect way to use up leftover Halloween candy if you didn’t get enough trick-or-treaters… or if you impulse-bought too much chocolate on sale on November 1st 🙂 Mix and match your favorite Halloween candy with our vanilla and chocolate cookie doughs, or try one of the combinations we made, using the recipe below!

Notes

Candy toppings: Amounts listed for each type of candy-themed cookie are for 1 full batch of base dough. (So if you want to use 1 batch of vanilla dough for 2 different types of cookies, for example, you would need to halve the amounts of candy ingredients).
Adding dry ingredients to wet ingredients: Be careful not to over-mix your dough! Scrape the bottom and sides of the bowl to make sure all the dry ingredients are incorporated, but don’t mix more than you need to.
Scooping cookie dough: We use this cookie scoop to get perfectly sized cookies! Just grease it lightly with cooking spray before using and the dough won’t get stuck in it.
Baking time: To get perfectly gooey cookies, take them out of the oven a little before you think you should. They should just be starting to firm up around the edges.
