Kit Kat Cookies Ingredients
Unlock the secret to delicious cookies with these essential ingredients!
For the Cookie Base

• Eggs (1 whole + 1 yolk) – Binds the mixture and enhances the chewiness; don’t substitute easily without affecting results.
• Vanilla Extract – Opt for real vanilla to elevate flavor depth.
• All-Purpose Flour – Acts as the structure; substituting without adjustments can affect texture.
• Cocoa Powder – Adds a rich chocolate flavor; feel free to omit for classic cookies.
• Baking Soda – Essential for leavening; verify its freshness for best results.
• Salt – Balances sweetness while enhancing overall flavors.
For the Chocolate Mix

Step‑by‑Step Instructions for Kit Kat Cookies
Step 1: Prep the Oven
Begin by preheating your oven to 350°F (175°C). This ensures it reaches the ideal temperature for baking your Kit Kat Cookies, helping them rise perfectly while maintaining a chewy center. Prepare your baking sheets by lining them with parchment paper to prevent sticking and make cleanup a breeze.
Step 2: Cream Butter and Sugars
In a large mixing bowl, combine softened unsalted butter, brown sugar, and granulated sugar. Using a hand mixer or stand mixer, beat the mixture on medium speed until it becomes light and fluffy, about 2-3 minutes. This step creates a rich base for your cookies, enhancing their chewy texture and overall flavor.
Step 3: Incorporate Eggs
Add one whole egg and one egg yolk to the creamed mixture, blending well after each addition. Then, pour in the vanilla extract and mix until fully incorporated. This combination not only binds the ingredients together but also contributes to the delightful chewiness of your Kit Kat Cookies.
Step 4: Mix Dry Ingredients
In a separate bowl, whisk together all-purpose flour, cocoa powder, baking soda, and salt until well combined. Gradually add this dry mixture to your wet ingredients, stirring gently until it just comes together. Be careful not to overmix, as this will ensure your cookies remain tender and delicious.
Step 5: Add Chocolates
Fold in chocolate chips and the chopped Kit Kat bars, distributing them evenly throughout the dough. The Kit Kat pieces will offer a delightful crunch, contrasting beautifully with the soft cookie base. This step is where the magic happens, as the flavors meld to create irresistible Kit Kat Cookies.
Step 6: Scoop and Bake
Using a large cookie scoop, drop dollops of dough onto the prepared baking sheets, leaving enough space between each to allow for spreading—about 2 inches apart. Bake in your preheated oven for 10-12 minutes or until the edges are set and the centers look slightly underbaked. They will firm up as they cool.
Step 7: Cool Down
Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes. This resting period allows them to firm up and makes transferring easier. Afterward, carefully move the cookies to a wire rack to cool completely and enjoy the sweet aroma of your fresh Kit Kat Cookies.

Make Ahead Options
These Chewy Kit Kat Cookies are fantastic for busy home cooks looking to save time! You can prepare the cookie dough up to 24 hours in advance by mixing all the ingredients as directed, then covering and refrigerating the dough. This not only allows for convenient batch baking later but also helps the flavors to develop further for even tastier cookies. When you’re ready to bake, simply scoop out the desired number of cookies and place them on a baking sheet, adjusting the baking time as needed since chilled dough may take a couple of extra minutes to bake. Rest assured, your Kit Kat Cookies will be just as delicious, and you’ll have delightful treats ready with minimal effort!
How to Store and Freeze Kit Kat Cookies
Airtight Container: Store your Kit Kat Cookies in an airtight container at room temperature for up to 3 days to maintain their soft texture and rich flavor.
Freezer: For longer storage, freeze the cookies in a single layer on a baking sheet, then transfer to a freezer bag or container, where they will last up to 3 months.
Thawing: To enjoy frozen cookies, simply take them out and let them thaw at room temperature for about 15-20 minutes, or warm them slightly in the microwave for a gooey delight.
Reheating: If you’ve stored cookies in the fridge, reheat in the microwave for 10-15 seconds or in a 350°F (175°C) oven for a few minutes to restore that fresh-baked feel.
Expert Tips for Kit Kat Cookies
-
Room Temperature Butter: Ensure your butter is at room temperature for optimal creaming, creating the perfect chewy texture in your Kit Kat Cookies.
-
Accurate Measurements: Measure your ingredients accurately, preferably by weight. This prevents common mistakes that can lead to dry or overly dense cookies.
-
Avoid Overbaking: Keep a close eye on your cookies; they should look slightly underbaked when you take them out. They will continue to firm up as they cool, ensuring a soft center.
-
Choosing Candy Wisely: If you’re considering using other candy, check their moisture content. Some bars may change the texture of your cookies, so stick with similar candies for best results.
-
Mixing Technique: Be gentle when combining dry and wet ingredients. Overmixing can lead to tough cookies, while a light touch ensures a tender bite with the delightful crunch of Kit Kats.
Kit Kat Cookies Recipe FAQs
How do I choose the best Kit Kat bars for this recipe?
Absolutely! When selecting Kit Kat bars, look for those with minimal damage to avoid any weird textures in the cookie. Fresh bars, with intact wrappers, are ideal as they’ll keep the chocolate and crispiness intact. If you’re not a fan of Kit Kats, consider substituting with similar textured candy bars like Twix or Snickers for a delightful twist!
How long can I store my Kit Kat Cookies?
For the freshest experience, store your Kit Kat Cookies in an airtight container at room temperature for up to 3 days. This will keep them delightfully soft and flavorful. If you want to prolong their life, you can freeze them, which can keep them good for up to 3 months. Just ensure they’re well-wrapped to prevent freezer burn!
Can I freeze Kit Kat Cookies for later? How?
Absolutely! Freezing your Kit Kat Cookies is a great option. To do this, first, place the cookies in a single layer on a lined baking sheet. Freeze them for about an hour until they are solid, then transfer them to a freezer-safe bag or container, where they will last up to 3 months. When you’re ready to enjoy, allow them to thaw at room temperature for 15-20 minutes.
What should I do if my cookies spread too much while baking?
Very commonly, cookie spreading can happen if your butter is too warm or if there’s too much liquid in your dough. Next time, make sure to use chilled butter (but not too cold) and check your measurements. You can also try chilling the dough for 15-30 minutes before baking to help control spread. If they still spread, consider adding a bit more flour, a tablespoon at a time, until the desired consistency is reached.
Are there any dietary considerations for these Kit Kat Cookies?
When it comes to allergies, keep in mind that Kit Kat bars contain wheat, milk, and soy, which may not be suitable for those with allergies. If you have any specific dietary restrictions, look for gluten-free chocolate bars or dairy-free options that can replicate the sweetness and crunch of the Kit Kat. Just remember to read labels carefully!
What’s the best way to reheat leftover Kit Kat Cookies?
To bring back the fresh-baked feel, reheat your Kit Kat Cookies in the microwave for about 10-15 seconds, or pop them in a 350°F (175°C) oven for a few minutes. Doing this helps revive their delightful chewy texture and the chocolate becomes even gooier—so scrumptious!
