Leftover Candy Cookies Recipe

Sharing is caring!

Jump to Recipe

Are you finding yourself with leftover candy bars after Halloween? If you’re looking for ways to use up some of your kiddos’ Halloween haul, these delicious candy bar cookies are for you!

What to Do with Leftover Halloween Candy?

Thanks to my mom and grandma, my house was definitely the place where there was ALWAYS a fresh batch of cookies growing up. Whether it was just me having friends over or we were hosting, there was always a sweet treat ready to share. So at a young age I learned the importance of having a couple of go-to cookie and bar recipes at the ready!

These candy bar cookies are a twist on my go-to chocolate chunk cookie recipe, and are a great way to use up all those mini candy bars you get after Halloween (and Easter too).

You’ll Love these Leftover Candy Cookies!

So Easy! Simply measure, mix, scoop, and bake.

Soft and chewy texture. These cookies have a soft and chewy center, with edges that are just set for a perfect bite.

Ready to enjoy in 30 minutes! A single batch of these candy bar cookies will take you approximately 30 minutes to make. Your total bake time may change depending on the size of your baking trays, and how many trays of cookies you bake at one time.

A fun way to repurpose Halloween candy. If the kiddo’s are slowing down on their candy stash (or maybe you NEED them to slow down on it…ha!), this sweet treat is a fun way to use up some of those fun size candy bars. See the ‘ingredients needed’ section for a list of what type of candy bars will work best in this recipe.

Candy Cookies Recipe Ingredients

Ingredients needed to make leftover Halloween candy cookies.
  • Salted Butter. I grew up using salted butter in baking, and still do to this day. If you’d prefer to use unsalted butter, just replace it 1-for-1 with the salted butter in the recipe and add an extra pinch of salt too.
  • Granulated Sugar. Granulated sugar both sweetens your cookies and also helps them remain soft and moist too! We’re talking about cookies with that perfect chewy center here.
  • Brown Sugar. Brown sugar contributes to a nice and chewy cookie (in addition to sweetening). You can use either light brown sugar and dark brown sugar in this cookie recipe. Light has a more subtle flavor than dark, due to a lower molasses content. In addition to more robust flavor, dark brown sugar will make your cookies a little bit darker in color too (not a big deal!). I tend to use whichever I have in my pantry at the time.
  • Vanilla Extract. Vanilla extract adds depth of flavor to our cookie recipe.
  • Large Egg. Using whole eggs helps to provide structure, leavening, and moisture to our cookies.
  • Salt. Salt is used in baking to enhance flavors and create balance (especially with the sweetness of the candy pieces in this recipe). 
  • Baking Soda. Using baking soda as our leavening agent helps our cookies rise and also helps to create chewy cookies.
  • All-Purpose Flour. All-purpose flour is ideal for baking cookies because it has the optimal protein range for this type of baking. When properly baked, all-purpose flour also contributes to cookies having a nice, chewy texture. Plus, it’s a common pantry staple for most people and is easy to find at your local grocery store, Target, Walmart, or Costco too!
  • Candy Bars of Choice. You will put candy bar pieces into your cookies (like you would do with chocolate chips in CCCs). Some of the best candies to cut into pieces for this recipe include: Kit Kats, Milky Way, Reese’s Peanut Butter Cups, Snickers, Hershey Bars, Crunch Bars, Butterfinger Bars, and m&m’s. Basically all the chocolate candy bars you’d typically get while trick-or-treating. If you have other fun size candy bars on hand that aren’t listed, give them a try! And I’m not going to fault you for throwing in a handful of candy corn into your dough if you’re feeling it. 

See recipe card below for a full list of ingredients and measurements.

How to Make Candy Cookies

Preheat the oven and set out baking pans: Preheat your oven to 375°F. Get cookie sheets ready (with the option to line them with parchment paper if preferred).

Gently chop your extra Halloween candy into bite-sized pieces and set aside.

Place softened butter into a large bowl. If needed, soften the butter in a microwave-safe bowl in the microwave (this takes about 20-30 seconds from refrigerated). No big deal if the butter melts a little!

Add the granulated sugar and brown sugar to the softened butter and cream together. The mixture should look a bit fluffy and a little grainy due to the granulated sugar.

Add the egg and the vanilla extract to the bowl and stir until combined.

Slowly add your dry ingredients (the salt, baking soda, and all-purpose flour) into the bowl and stir until a dough is formed.

Gently stir the pieces of your favorite candy bars into the dough until they are well distributed (reserving some of the chopped candy to press into the dough balls before baking if desired).

Scoop the cookie dough onto your cookie sheet using a medium cookie scoop (alternatively scooping out 2 Tablespoon portions). Be sure to leave about 2 inches of space between the dough balls. If you reserved some candy pieces, gently press a few pieces into the top of each dough ball.

Bake each tray of cookies for 8-10 minutes. When the cookies are ready, the centers will be puffed up and the edges will look set. For super chewy cookies, do not overbake (they will continue to set up after they’re pulled out of the oven).

Leave the cookies on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.

Candy Cookies Recipe Variations

  • Add in chocolate chips! If you only have a little candy left over, or just want to have a little fun, substitute half of the candy with chocolate chips! You can use milk chocolate chips, semi-sweet chocolate chips, dark chocolate chips, white chocolate chips, peanut butter chips… have fun with it!
  • Use unsalted butter. I personally love to bake with salted butter, but if you prefer, swap out the salted butter 1-for-1 with unsalted butter and increase the amount of salt noted in the recipe card to ½ teaspoon.

Possible Dietary Restrictions?

This candy bar cookies recipe is vegetarian as written, and can easily be altered to be a dairy free or gluten free cookie recipe too!

  • To make these dairy free, replace the butter with vegetable or canola oil. As a standard rule of thumb, you can use oil in place of butter by using ¾ the amount of butter called for in the recipe. So for a single batch of our cookie recipe, replace the listed ½ cup of salted butter with 6 Tablespoons of canola or vegetable oil. I would also recommend increasing the amount of salt used to ½ teaspoon (since we left out the salted butter).
  • Make these into gluten free cookies by replacing the all-purpose flour called for in the recipe with the one-to-one gluten free flour alternative of your choice.
  • If making these for someone with a food allergy, it would also be wise to verify the candy you’re using is dairy free and/or gluten free (this may be a little tricky with Halloween candy, so do your research!).

Expert Tips for Candy Cookies

Use a cookie scoop to get all of your cookies to be the same size! We use our cookie scoops ALL THE TIME in our kitchen. So while not a necessity, they’re definitely a handy tool to have as a part of your kitchen equipment. I personally like to use a medium cookie scoop for this recipe. But if you love giant cookies, try using a large cookie scoop instead!

Do the “cookie scoot” to get perfectly round cookies! This is a simple baking hack where you use use a circular cookie cutter (or a round glass or jar that’s larger than your cookie) to gently “scoot” your cookies in a circular motion right after you pull them out of the oven to help mold the edges into a perfectly round shape.

You can use your stand mixer too! If preferred, you can mix up your cookie dough in your stand mixer! I recommend using a paddle attachment when doing this.

Storing Leftover Candy Cookies

Fully cooled cookies can be stored in an airtight container at room temperature for up to 5 days (if they last that long!). Leftover Halloween candy cookies can also be frozen to enjoy at a later date!

How to Freeze Before Baking

Freezing cookie dough balls is a great way to enjoy fresh-baked cookies at a later date! To do so, follow the recipe card up until the dough is formed. Then scoop dough into balls onto a wax paper lined cookie sheet (making sure they’re not touching) and do a “flash freeze” of the dough balls by placing them into the freezer to chill for 1 hour. Once the cookie dough balls are cold and solid, simply place them into a labeled freezer bag to bake another time.

You can freeze cookie dough balls for up to 3 months, and bake them from frozen! To do so, just add 2-3 minutes of baking time to the time listed on the recipe card when you’re ready to enjoy them.

How to Freeze Cookies After Baking

Ensure your cookies are completely cooled before freezing. Then place the cookies into a large freezer bag or an airtight container in your freezer for up to 3 months. To help prevent your cookies from sticking together, place parchment paper between them. When you’re ready to enjoy, simply thaw the frozen cookies in the refrigerator or on the countertop.
