Ingredients You’ll Need

- 2 large eggs: Essential for binding the ingredients and giving structure.
- 1 teaspoon pure vanilla extract: A must for enhancing the flavors; always choose pure for the best taste!
- 2 1/2 cups all-purpose flour: The base of the cookie dough; sifting can add to the fluffiness.
- 3.4 ounce box instant vanilla pudding mix: This secret ingredient adds an incredible creaminess and softness to the texture.
- 1 teaspoon kosher salt: Balances sweetness and brings out the flavors.

How to Make Kit Kat Cookie Bars
- Preheat your Oven: Begin by preheating your oven to 350 degrees F. while you prepare your baking dish.
- Prepare the Baking Dish: Line a 9 x 13 inch baking dish with parchment paper, letting it hang over the edges for easy removal later.
- Mix the Butters and Sugars: In a large bowl, beat together 2 sticks of softened salted butter, 1 cup of dark brown sugar, and 1/2 cup of granulated sugar until creamy and well combined—a few minutes should do.
- Incorporate Eggs and Vanilla: Add in 2 large eggs and 1 teaspoon of pure vanilla extract, stirring until everything is properly mixed.
- Combine the Dry Ingredients: Gradually mix in 2 1/2 cups of all-purpose flour, the box of vanilla pudding mix, 1 teaspoon of kosher salt, and 1 teaspoon of baking soda. Mix just until a dough forms.
- Add Chocolate Chips: Fold in 1 cup of mini chocolate chips, ensuring they are evenly distributed throughout the dough.
- Transfer to Baking Dish: Spoon the dough into the prepared baking dish, pressing it down evenly.
- Top with Kit Kat Bars: Break your Mini Kit Kat Bars into pieces and evenly distribute them over the top of the dough.
- Bake: Place the baking dish in the oven and bake for 35-38 minutes, until the edges are golden and a toothpick inserted in the center comes out clean.
- Cool and Cut: Remove from the oven, let cool completely, and then cut into squares. Enjoy warm or at room temperature.
Storing & Reheating
Store your Kit Kat Cookie Bars at room temperature in an airtight container for up to five days for optimal freshness. For longer storage, you can refrigerate them for up to a week, but be sure to use a container that won’t trap moisture. If you want to freeze them, wrap each square individually and place in a freezer-safe bag; they’ll keep for up to three months. When ready to enjoy, simply reheat in the microwave for about 10-15 seconds for that fresh-baked feel. The chocolate may soften slightly when reheated, enhancing the indulgent experience!
Chef’s Helpful Tips
- Avoid overmixing the dough after adding the flour; overworking can lead to tougher cookies.
- For best results, make sure your butter is softened but not melted; this ensures the right texture.
- Room temperature eggs will mix more thoroughly, giving your bars a better rise.
- Don’t rush the cooling process; cutting them too soon can result in a messy square. Patience is key!
- Feel free to experiment with mix-ins—try adding nuts or different types of candy for added flavor.
The comforting taste of these Kit Kat Cookie Bars will surely captivate your senses. Whether you’re sharing them with friends or enjoying them solo during a cozy evening at home, every bite is a joyful reminder of all things sweet.
