Looking for something new to add to your holiday baking tradition? These Kit Kat Cookies are a kicked up version of a classic chocolate chip cookie.

The crunch of the Kit Kat candy adds delicious texture and another kick of chocolate. What’s not to love?

Ingredients for Kit Kat Cookies

Here’s what you’ll need to make these candy filled cookies:

  • Butter: Make sure it’s room temperature. I use unsalted. If all you have is salted, leave out the salt in the recipe.
  • Brown sugar: Provides a caramelized flavor and a chewy texture.
  • Granulated sugar: Adds more sweetness and combines well with brown sugar.
  • Eggs: You’ll need a whole egg and an additional egg yolk for this recipe. The extra egg yolk provides richness and will yield an extra chewy, tender cookie.
  • Vanilla extract: Adds lots of flavor to the dough.
  • All-purpose flour
  • Baking soda
  • Kosher salt
  • Kit Kats: You can buy the fun size kit kats or full size. They are going to be chopped up so whichever you have will work. You’ll need 1 cup of roughly chopped candy.
  • Mini chocolate chips: Because why not add a little more chocolate?!

How to Make Kit Kat Cookies

Add the room temperature butter, brown sugar and granulated sugar to a stand mixer or large bowl. Cream until light and fluffy, about 3 minutes. You can also use a hand mixer or do this by hand.

Add egg, egg yolk and vanilla. Mix together. Add dry ingredients and mix until the dough just comes together.

By hand, mix in chopped kit kats and mini chocolate chips.

Refrigerate the Dough

Do these cookies absolutely need to be refrigerated before baking? No, they don’t but let me tell you why I recommend it.

When cookie dough is chilled before baking, it solidifies the fat in the recipe, butter in this case. When this happens, the cookies won’t spread as much and you’ll have a thicker, chewier cookie.

I love a thick cookie and I really preferred it in this recipe because of the big chunks of candy mixed throughout. In my testing, when the cookies spread more, they were crispier and then they didn’t have the mix of chewy and crispy.

I recommend chiling the dough for at least an hour but you could also make the dough the night before and chill all night. Then all you have to do the next day is bake them up.

Portion Dough and Bake

I love using my cookie scoop whenever I’m baking. You get even sized cookies every time and it gets them portioned out quickly.

Bake on parchment lined baking sheets (or use nonstick spray) until they are lightly golden.
