Irresistibly Fudgy Kit Kat Butterscotch Brownies: The Ultimate Decadent Dessert!
There’s something universally comforting and utterly delicious about a perfectly baked brownie. For me, brownies aren’t just a dessert; they’re a passion. And when it comes to brownies, the fudgier, the better! I’ve been on a lifelong quest for the ultimate fudgy brownie recipe, and I’m thrilled to say I’ve found a new contender that has stolen my heart: these incredible Kit Kat Butterscotch Brownies. This recipe, which I initially stumbled upon and then rediscovered through a friend’s glowing recommendation, combines everything you could possibly want in a dessert: rich chocolate, crunchy candy, and a sweet, gooey topping. It’s a symphony of textures and flavors that will undoubtedly become a staple in your baking repertoire.
Why These Kit Kat Butterscotch Brownies Are a Must-Try
What makes these brownies so special? It’s the delightful layering of indulgence. First, you start with a foundational brownie layer that is unbelievably fudgy and moist, packed with intense chocolate flavor. This isn’t just any brownie; it’s the kind that melts in your mouth and leaves you craving more. Nestled within this chocolatey dream are crunchy Kit Kat bars, adding a fantastic textural contrast with their signature wafer and milk chocolate. And as if that weren’t enough, the entire creation is generously crowned with a smooth, golden butterscotch topping, providing a sweet, caramel-like finish that ties all the flavors together. The combination is undeniably over-the-top, yet perfectly balanced and utterly irresistible. They’re rich, satisfying, and guaranteed to put a smile on anyone’s face.
The Origin Story: From Pin to Pan
Like many great recipes, this one came to me in a roundabout way. I actually pinned it on Pinterest what feels like an eternity ago, tucked away in one of my many “must-try desserts” boards. As often happens, it got lost in the digital shuffle until a friend, who had also pinned it (likely from my board!), decided to make them. Her enthusiastic Facebook post, raving about how amazing they were, immediately jogged my memory. It was one of those moments where everything clicked, and I knew I absolutely had to make them. Her rave reviews were all the assurance I needed that these brownies were destined for greatness, and I was not disappointed!
Perfect for Any Occasion: Girls’ Weekend & Beyond
A couple of weeks ago, I had the perfect excuse to whip up a batch: a much-anticipated girls’ weekend in Denver. What better way to fuel laughter, wine, and games in a hotel room than with some seriously killer brownies? These Kit Kat Butterscotch Brownies were an absolute hit with the girls. They’re the kind of treat that elevates any gathering, turning a simple get-together into a memorable occasion. Imagine unwinding with your closest friends, sharing stories, and indulging in these decadent squares – it’s pure bliss! But these brownies aren’t just for special occasions; they’re equally perfect for a cozy night in, a potluck, a birthday party, or just because you deserve a little sweet escape.
Crafting Your Fudgy Foundation: Tips for the Best Brownie Base
The secret to a truly outstanding brownie lies in its base. This recipe ensures a super fudgy texture that’s dense, moist, and deeply chocolatey. To achieve this, several factors are key. Using melted butter helps create that desirable chewy texture, while a good quality unsweetened cocoa powder is essential for a rich, intense chocolate flavor without being overly sweet. It’s also important not to overmix the batter once the flour is added; this prevents the brownies from becoming tough and ensures they stay delightfully fudgy. A gentle hand and mindful mixing will yield the perfect brownie foundation, ready for its delicious toppings.
The Kit Kat Krunch: A Delightful Surprise
The Kit Kat bars are more than just a sweet addition; they provide a fantastic textural counterpoint to the soft, fudgy brownie. As they bake, the chocolate softens, and the wafer retains a slight crunch, creating a delightful surprise in every bite. Pressing them into the batter before baking ensures they are perfectly integrated, becoming a delightful part of the brownie’s core. This innovative inclusion truly sets these brownies apart, making them a fun and exciting dessert option.
Golden Drizzle: The Butterscotch Bliss
The final touch, the butterscotch topping, adds a beautiful golden sheen and another layer of rich sweetness. Butterscotch chips melt down into a smooth, luscious sauce that complements the chocolate and Kit Kat perfectly. The slightly salty-caramel notes of butterscotch beautifully enhance the deep chocolate, creating a complex flavor profile that will tantalize your taste buds. Don’t skip this step – it’s what truly elevates these from great brownies to absolutely phenomenal ones!
Unleashing Your Creativity: Candy Bar Substitutions
While Kit Kats are fantastic in this recipe, don’t feel limited! If you’re out of Kit Kats, or simply want to experiment, these brownies are incredibly versatile. I’m sure many of you still have plenty of candy lingering around from Halloween, making this the perfect opportunity to get creative! Other candy bars that would be absolutely delicious include:
- Snickers: The combination of peanuts, caramel, and nougat would add a wonderful chewy and nutty dimension.
- Twix: The shortbread cookie, caramel, and chocolate would introduce another layer of satisfying crunch and chewiness.
- Butterfinger: For those who love a crispy, peanut-buttery crunch, Butterfinger pieces would be an excellent choice.
- M&M’s: While not a candy bar, colorful M&M’s would add a delightful pop of color and chocolatey crunch.
- Reese’s Peanut Butter Cups: If you’re a fan of the chocolate and peanut butter combo, chopped Reese’s would be a dream.
- Oreo Cookies: Crushed Oreos could add a different kind of chocolatey crunch and creaminess.
Feel free to experiment with your favorite chocolate or candy! The base brownie recipe is so good that it can handle a wide variety of additions. I truly believe I’ve found a new go-to fudgy brownie recipe here; it was just that delicious!
Beyond the Basics: Enhancing Your Kit Kat Butterscotch Brownies
To ensure your brownies are nothing short of perfect, consider these additional tips:
- Pan Size Matters: This recipe calls for an 8-inch baking pan, which yields thicker, fudgier brownies. If you use a 9×13-inch pan, your brownies will be thinner and may bake faster, so adjust your baking time accordingly and keep a close eye on them.
- Don’t Overbake: This is crucial for fudginess! Brownies continue to cook slightly after being removed from the oven. A tester inserted into the center should come out with moist crumbs, but not wet batter. If it comes out completely clean, they might be overdone.
- Cool Completely: Resist the urge to cut into them while warm! Allowing the brownies to cool completely (or even chilling them in the refrigerator) not only makes them easier to cut cleanly but also allows the flavors to meld and the texture to set perfectly.
- A Pinch of Salt: While not in the original ingredients, a tiny pinch of sea salt sprinkled over the top of the butterscotch topping just before it sets can wonderfully enhance all the sweet flavors, providing a gourmet touch.
- Garnish for Show: If serving for a special occasion, consider adding a few extra chocolate sprinkles or even some chopped Kit Kat pieces on top of the butterscotch for visual appeal.

Ingredients
- 1 1/2 cup granulated sugar
- 3/4 cup all-purpose flour
- 3/4 cup unsweetened cocoa powder
- 3 whole large eggs
- 3/4 cup butter, melted
- 12 Kit Kat Bars, (fun sized), unwrapped
- 1 11oz pkg butterscotch chips
- 1 Tablespoon chocolate sprinkles
Instructions
-
Preheat oven to 375 degrees F (190 degrees C). Line an 8-inch baking pan with foil, leaving an overhang on the sides for easy lifting, and spray with non-stick cooking spray.
-
In a large bowl, combine the melted butter and cocoa powder. Mix until thoroughly combined and smooth. Add the eggs and granulated sugar, and mix well until creamy and uniform. Gently stir in the all-purpose flour until just combined, being careful not to overmix. Pour the brownie batter into the prepared baking dish. Evenly press the unwrapped Kit Kat bars into the batter. Bake for approximately 25 minutes. A toothpick or tester inserted into the center should come out mostly clean, with a few moist crumbs attached, indicating a fudgy texture. Remove from the oven and allow to cool completely in the pan on a wire rack.
-
Once the brownies are completely cooled, place the butterscotch chips in a microwave-safe bowl. Microwave in 30-second intervals, stirring after each, until the chips are fully melted and smooth. Pour the melted butterscotch over the cooled brownies, spreading it evenly. Immediately top with chocolate sprinkles for an added decorative touch and a hint of extra chocolate. Allow the butterscotch topping to set and cool completely before attempting to slice and serve. For cleaner cuts, you can refrigerate the brownies for about 30 minutes after the butterscotch has set.

Serving and Storing Your Decadent Treat
These Kit Kat Butterscotch Brownies are delicious on their own, but if you want to elevate the experience, consider serving them warm with a scoop of vanilla bean ice cream. The contrast of warm brownie and cold ice cream is simply divine! A dollop of whipped cream or a drizzle of extra chocolate sauce would also be fantastic. To store leftovers, simply place them in an airtight container at room temperature for up to 3-4 days. If you prefer a firmer brownie, you can store them in the refrigerator, which also extends their freshness. For longer storage, wrap individual brownies tightly in plastic wrap and then foil, and freeze them for up to 2-3 months. Thaw at room temperature or warm briefly in the microwave for a quick treat.
Frequently Asked Questions (FAQ)
- Q: Can I use different chocolate bars or candies?
- A: Absolutely! This recipe is very adaptable. Snickers, Twix, Butterfinger, or even chopped Reese’s Peanut Butter Cups would be excellent choices to substitute for Kit Kats. Feel free to use your favorite candy bar or even mix in some chocolate chips or M&M’s.
- Q: How do I achieve the fudgiest brownies?
- A: The key to fudgy brownies is not to overbake them. Remove them from the oven when a toothpick inserted into the center still has moist crumbs attached, but no wet batter. They will continue to cook slightly from residual heat. Using melted butter and cocoa powder also contributes to their rich, dense texture.
- Q: How long do these brownies last?
- A: Stored in an airtight container at room temperature, these brownies will stay fresh for 3-4 days. If refrigerated, they can last up to a week. For longer storage, they freeze wonderfully for up to 2-3 months.
- Q: Can I make these brownies ahead of time for a party?
- A: Yes, these brownies are perfect for making ahead! They often taste even better the next day as the flavors have more time to meld. Just store them properly until you’re ready to serve.
- Q: My butterscotch topping is too thick/thin. What can I do?
- A: If your butterscotch seems too thick after melting, you can add a tiny splash of milk or cream (about a teaspoon at a time) and stir until it reaches your desired consistency. If it’s too thin, it might be due to overheating; next time, microwave in shorter intervals and stir thoroughly. It will thicken as it cools.
- Q: What size baking pan should I use?
- A: This recipe is designed for an 8×8-inch baking pan, which yields thick, generous brownies. If you use a larger pan, such as a 9×13-inch, your brownies will be thinner, and the baking time will need to be reduced. Keep a close eye on them to prevent overbaking.
These Kit Kat Butterscotch Brownies are more than just a dessert; they’re an experience. They are the perfect blend of chocolatey indulgence, crunchy texture, and sweet butterscotch bliss that will satisfy any sweet tooth. Whether you’re baking for a special gathering or simply treating yourself, this recipe is guaranteed to be a new favorite.
