Ingredients You’ll Need

Every ingredient in Kit Kat Cookies has a crucial part to play—don’t skimp or swap unless you must! These key items work together to build the fudgy, chewy texture and the vibrant chocolate flavors that make these cookies unforgettable.

• Unsalted butter (250g): Soft butter makes for the perfect creamy base and ensures a rich, chewy texture in every bite.
• Granulated sugar (200g): Provides sweetness and helps the cookies spread just right while baking.
• Light or dark brown sugar (120g): Adds a subtle molasses note and keeps the cookies perfectly soft and moist.
• Egg (1, at room temperature): Binds everything together and adds structure to the dough.
• Egg yolk (1, at room temperature): Gives the cookies an extra boost of richness and chewiness.
• Vanilla extract (1 tsp): Rounds out the chocolate flavors and adds warmth to the dough.
• All-Purpose Flour (200g, sifted): The backbone of the cookie, sifted for a light, even crumb.
• Cocoa (80g, sifted): For deep, chocolatey flavor and that dark, irresistible color.
• Kosher salt (1 tsp): Essential to balance the sweetness and intensify the chocolate.
• Baking powder (½ tsp): Helps lift the cookies, creating just the right amount of puff.
• Baking soda (½ tsp): Works alongside the powder to ensure your cookies stay soft but not cakey.
• Kit Kats (300g, coarsely chopped, plus extra for the tops): The star of the show—crunchy, chocolatey, and totally addictive!
• Chopped chocolate (150g, preferably dark): Adds pools of melty goodness and complements the Kit Kat pieces beautifully.

How to Make Kit Kat Cookies

Step 1: Prep Your Baking Sheets

Start by preheating your oven to 350°F (180°C) and lining two to three baking sheets with parchment paper. Lining the trays keeps your Kit Kat Cookies from sticking and makes cleanup a breeze. Getting everything ready ahead of time guarantees a stress-free baking experience.

Step 2: Cream the Butter and Sugars

Place your room temperature unsalted butter, granulated sugar, and brown sugar into the bowl of a stand mixer fitted with a paddle attachment. Beat on medium speed for about 2 to 3 minutes—your goal is a fluffy, pale mixture. This airy butter base will give your Kit Kat Cookies a seriously tender chew.

Step 3: Add Eggs and Vanilla

Crack in the egg and additional egg yolk, then pour in the vanilla extract. Mix until everything is thoroughly combined, scraping down the bowl as needed. The extra yolk really ups the richness, making these cookies extra delicious.

Step 4: Mix in the Dry Ingredients

Sift together your flour, cocoa, kosher salt, baking powder, and baking soda. Add these dry ingredients to the butter mixture all at once and blend on low until just combined. Don’t overmix—you want to keep the dough tender and fudgy!

Step 5: Add Kit Kat and Chocolate

Now for the fun part: gently fold in the chopped Kit Kats and the chopped dark chocolate. Use a rubber spatula to make sure everything is evenly distributed. This way, you’ll get bits of melty chocolate and crunchy wafer goodness in each and every bite.

Step 6: Scoop and Top the Dough

Using a ¼ cup cookie scoop (or a large spoon), drop balls of dough onto the prepared baking sheets, leaving plenty of room for spreading—about six cookies per half sheet works well. For an extra touch, press a few additional Kit Kat chunks onto the tops of each dough ball. This gives every cookie a gorgeous, bakery-style look.

Step 7: Bake to Perfection

Bake your Kit Kat Cookies for 15 to 16 minutes, or until set around the edges but still soft in the center. If you like your cookies perfectly round, gently “scoot” them into shape using a round cookie cutter or the edge of a spatula right after they come out of the oven.

Step 8: Cool and Enjoy

Let the cookies cool on the pan for 15 to 20 minutes before transferring them to a wire rack to finish cooling. This helps them set up nicely and guarantees those melty Kit Kat bits stay put. Now comes the hardest part—waiting before you dig in!

How to Serve Kit Kat Cookies

Garnishes

For the ultimate Kit Kat Cookies experience, I love sprinkling a little flaky sea salt on top while they’re still warm from the oven. It melts slightly and brings out all the complex chocolate notes. For a party-ready look, add a half-stick of Kit Kat or a dusting of cocoa powder before plating.

Side Dishes

While these cookies are a showstopper on their own, you can pair Kit Kat Cookies with a cold glass of milk, a mug of hot chocolate, or some vanilla ice cream. The classic combo of cookies and cream never fails, but fresh strawberries or a berry compote are also incredible with the chocolate and wafer crunch.

Creative Ways to Present

If you really want to wow your guests, try stacking Kit Kat Cookies on a cake stand for a playful dessert centerpiece. For parties, wrap each cookie in cellophane with a ribbon, or even make jumbo cookie ice cream sandwiches using your favorite ice cream flavor. These cookies look and taste amazing, so don’t be afraid to get creative!

Make Ahead and Storage

Storing Leftovers

To keep your leftover Kit Kat Cookies tasting fresh, pop them into an airtight container at room temperature. They stay soft and delightful for up to four days—if they even last that long!

Freezing

Want to have Kit Kat Cookies on hand for a rainy day? Cool the baked cookies completely and freeze them in a freezer-safe bag or container for up to two months. You can also freeze unbaked dough balls; just let them thaw slightly before baking.

Reheating

To enjoy a warm, just-baked cookie anytime, pop a cookie in the microwave for 10–15 seconds. This brings back their soft texture and gets those chocolate chunks nice and gooey all over again.

FAQs

Can I use other candy bars instead of Kit Kat?

Absolutely! While nothing beats the crunch of Kit Kat Cookies, you can experiment with your favorite chocolate bars for a fun twist. Just make sure to chop them into similar-sized pieces for even baking.

How do I make my cookies extra chewy?

The key is not to overbake your Kit Kat Cookies—take them out when the edges are set but the centers are still soft. The brown sugar and extra egg yolk help, too, ensuring every bite stays ultra chewy.

Can I make smaller cookies with this recipe?

Yes! Just use a smaller cookie scoop and reduce the baking time by a few minutes. Keep an eye on them so they don’t overbake—they’ll still have all the flavor and crunch you love in classic Kit Kat Cookies.

What kind of chocolate works best for this recipe?

I love using dark chocolate chunks for a richer contrast with the Kit Kat pieces, but milk or semi-sweet chocolate works beautifully too. Choose high-quality chocolate for the best taste and texture.

Do Kit Kat Cookies stay soft after baking?

They sure do! Thanks to the careful balance of ingredients, these cookies remain soft and fudgy for days. Just remember to store them in an airtight container to keep them from drying out.

Final Thoughts

If you’re ready to treat yourself or seriously impress friends and family, bake up a batch of Kit Kat Cookies. Once you taste that unbeatable combination of melty chocolate, tender cookie, and crisp Kit Kat wafer, you’ll wonder why you didn’t try it sooner. Go on—this recipe is pure happiness in cookie form!
