Jordan’s been a little sick this week; she’s got a fever and a cough. She missed school, has tons of work to catch up on, and watched hours and hours of Netflix.

I swear, Netflix Watch Instant is the best thing ever. She watched pretty much the entire series of Zac and Cody and Cake Boss. She slept through a lot of it, so I could have turned it off…but then I would have needed to wash the remotes.

I pretty much have been like Go Go Gadget Disinfectant all week. Touch forehead, use purell. Touch her hand giving her medicine, bathe hands in bleach. You know the drill.

To cheer her ups since she’s missing school, I made her cookies. Her appetite has not been affected! I’ve been craving regular chocolate chip cookies lately, but I wanted a new twist. I added Kit Kats, because that’s Jordan’s favorite.

Cookies are like chicken soup: they make everything better!

I’m in love with this chocolate chip cookie recipe. It’s the one I always use, except I cut it in half because I didn’t need a gazillion cookies. This makes 24 two-tablespoon sized cookies. You can use a one-tablespoon scoop as well, for a mini and more bite sized cookie (like these Toffee Chocolate Chippers).

The only other difference between these and that other recipe is that I forgot to melt the butter for these. I know, right? In my defense, I was making two other recipes, shooting two, and dealing with a kid with a fever bouncing off 103.

Guess what? They’re just as good with regular, creamed butter. And you don’t have to refrigerate them that long!

The beauty of this cookie recipe is that you can add whatever you want to it. Candy, different flavors of chocolate chips, toffee, whatever you want. For this batch I added chopped Kit Kat bars and white chocolate chips. I like the balance between the white chocolate and the Kit Kats. If I’d added milk or semi-sweet chocolate, I think the Kit Kat would have gotten lost. You can add your favorites!

Just a quick note: I broke my Kit Kats into the strips, then into thirds and mixed them in using a stand mixer. Mixing them in with the mixer breaks some of the chunks up even more and leaves some bigger. If you’re not using a stand mixer, you should chop the Kit Kats up a little more so you don’t have huge pieces in all your cookies.

If you like Kit Kats, you’ll love these! I’m kind of hoping they have magical healing powers.

Kit Kat Cookies


  • 1/2 cup unsalted butter, softened

  • 1/3 cup granulated sugar

  • 1/2 cup packed light brown sugar

  • 1 large egg

  • 1 1/2 teaspoons pure vanilla extract

  • 1/2 teaspoon baking soda

  • 1 1/2 cups all-purpose flour

  • 1/4 teaspoon salt

  • 1 1/4 cup Kit Kats, strips separated and broken into thirds (about 10 fun sized)

  • 1/2 cup white chocolate chips (or milk or semi-sweet)


  1. Cream butter and both sugars until combined.

  2. Combine flour, baking soda, and salt in a medium bowl. Stir and set aside.

  3. Turn mixer on low. Add egg, mixing completely. Mix in vanilla extract. Add flour mixture to the wet ingredients and mix until combined. Add Kit Kats and white chocolate chips. NOTE: if you’re not using a stand mixer, chop your Kit Kats smaller. If you are using a stand mixer, run it on medium-low speed for about 15 seconds. The Kit Kats will break up smaller during mixing.

  4. Important: Cover bowl with plastic wrap and chill dough for at least 2 hours. They taste best when baked from the refrigerator.

  5. Preheat oven to 350°. Line cookie sheets with parchment or silpat liners.

  6. Scoop out 2 tablespoon sized balls and place two inches apart on cookie sheet.

  7. Bake for about 10-12 minutes. 10 minutes will be slightly underdone (the way I love them) but if you like a more done cookie, let them bake an extra minute or two. Let cool for 5 minutes, and then remove from pans to cool completely.

  11. Man, I hope Jordan feels better! But this “Go Go Gadget Disinfectant ” made me laugh! These cookies look awesome Dorothy..I love the crunch that the Kit Kats would add!

  12. I LOVE kitkats! Ive baked them into bars, but never cookies. What have I been waiting for! They look great, Dorothy! 🙂

  13. I agree – a good cookie can make everything better! I adore your recipes!

  14. Yum! These look awesome, Dorothy. Totally healing cookies! 😉 I’ve been battling the flu for a week or so even though I am a germ freak (flu shots are obviously not enough of a defense!) so these look like the perfect “I want to feel pitiful and lay on the couch” cookies. I hope Jordan feels better and you don’t catch what she has! Sanitizer to the rescue!

  15. Oh, yum! You could have made a full recipe and saved some for me!!! lol

With so many recipes to test and photograph, I really hope you don’t get Jordan’s fever. All of the sugar should kill any germs she sends your way, right??

  21. What a nice treat for your little one — hope she is feeling better soon! These look so yummy!

  22. Hope Jordan feels better soon! being sick is the worst!

    I am in love with these cookies. Kit Kats are so fun and remind me of being a kid around Halloween. For some reason I always ate kit kats around Halloween. Anyway, love these!

  23. Hi Dorothy,
    You are such a cool mom. You allowed Jordn to watch netflix and made her cookies.
    Unfortunately my 5 yr old got sick too (has a krup cough). It sucks because she sounds like a seal when coughing.
    And now what sucks the most is I’m sick. I saw your post and honestly got happy. My fav. candy is kitkat. 🙂 I think I’ll make your cookies, I need something tasty! 🙂
    You rock!!

  24. Ummmm I love it. and ironically, I just had a kitkat today. Now I want to make these cookies!

  25. I hope Jordan feels better soon! I just recovered from two weeks of the worst flu ever so I can totally sympathize. Netflix and cookies make everything better! I love that you used Kit Kat, my favourite candy bar, here. These look fantastic, Dorothy!

  26. Hey i was just wondering if i can use kit kat chunky for this

  27. I vote we make kit kat cookies the new chicken soup! They look incredible; candy bars in cookies are just amazing. Kit kats are new to me, but I love the candy, and know these would disappear around here. Hope Jordan feels better soon and that you don’t get whatever she’s got!

  28. Today is Friday … I’m sure the healing powers have worked by now … at least I hope so! Kit Kats in cookies … winner 🙂

  29. I LOVE Kit Kat bars, but never thought about putting them in a cookie! I have to try these

  30. Oh Dorothy! You have the key to my heart! I love love love Kit Kat bars!

  31. Hi i tried baking the cookies just now and am wondering how come my batter is not moist? Its so dry and kinda hard to mold.. 🙁

  32. Hi Dorothy,
    These look delicious! I love Kit Kat bars! These are amazing looking. I could stuff my face with these and not feel a bit guilty! Totally pinning!

  33. I love the idea of these cookies! You’re right in that cookies make everything better! Coming off the heels of our vacation this weekend, my boyfriend came down with a nasty cold and I am trying to stay as far away from him as possible, I too cannot get sick before BYBC!

  34. Hi
    I’ve just made these and my family loved them –
    Even though I forgot to out the white choc chips in
    Thanks I have another recipe for my bake sale next week
    Hope Jordon is feeling better. 🙂

  35. Like a previous poster, I made them and the batter was dry. I couldn’t form a cookie, so I baked it in a 8×8 pan. I even made the base twice, just in case the butter and sugars weren’t creamed enough. I added the dry ingredients slowly to not over power the wet ingredients too, even cut back on the flour. Any advice?

    • Hi Niki, I’m sorry about that! (And thanks for alerting me to the other comment, somehow it got lost in my feed!) Can you let me know if you made any other changes to the recipe (besides cutting down on flour)? How much flour did you end up using? Was your butter room temperature or cold when starting? Did you use unsalted? How long did you chill them for? I know that, when the dough is chilled a long time (my other cookies from this same base are chilled longer) the dough gets very hard from the refrigerator and is difficult to scoop. Could that have been a the problem? Sorry for all the questions, I’m just trying to troubleshoot. 🙂

      • How much is one cup of flour? 150 grams?

      • From Google: “A cup of all-purpose flour, properly measured, should weigh 120 grams. The flour measured incorrectly by dipping the measuring cup into the flour can weigh anywhere from 150-160 grams. Try it out! That’s like 30% more flour than the recipe needs!”

    • Hi Niki, me again! 🙂 So I just went and remade the dough, because when I saw 2 1/2 cups of flour it made me wonder, and you’re right. I so apologize for any inconvenience! The recipe should have (and now does say) 1 1/2 cups. Again, thanks for alerting me to the issue, and I apologize! I hope that you’ll try them again. 🙂 With the 1 1/2 cups of flour the dough is soft, but not too sticky, when finished mixing. Once chilled it will be harder and difficult to scoop, but the end result is worth the arm workout. 🙂

  36. Must try these! Every Halloween I eat myself a bag of kit kats, just to mentally prepare myself for all the screaming sugar-high children, you know? Yum!! Hope that fever is gone!

  37. #2 on the directions says while butter mixture is cooling……
    Is the butter supposed to be warm/hot? Just making sure I didn’t miss something, LOL!
    Thanks! Tina

  50. I returned to check the recipe to see if it had been changed or someone else had commented on the high ratio of flour to other ingredients. I thought it high when weighing ingredients but I used the original 2 1/2 cups. I wasn’t going to comment since several others mentioned the typos in the recipe and got those corrected for others using the recipe but I have to note that though I found them dry and hard to shape and bake they did bake ok and weren’t crumbly as I might expect with so much dry vs. wet ingredients. So, it did work if more work to use the dough. The funny thing is I took a bunch of them (I doubled the recipe) to friends who love cookies at work (outside in a garden nursery) and they just loved them. They declared they “just melt in your mouth”. I told them it might be that the high flour gave them a “short” texture like shortbread that might be the reason. I just thought it was great that an error was found and corrected but it still produced a cookie that got high marks. HA Thanks for sharing another great recipe, Dorothy!
