It's messy. Let’s just start there. If you’ve ever unwrapped a candy bar with crispy peanut butter and spun taffy, you know the deal: neon-orange shards immediately find their way onto your shirt, the floor, and somehow, your eyebrows. It’s a chaotic eating experience. Yet, for over a hundred years, this specific texture profile—that strange, flaky, tooth-sticking magic—has remained a top-tier snack choice. We’re mostly talking about the Butterfinger, though the history of how we got here involves more corporate drama and food science than you’d probably expect from something you buy at a gas station for two bucks.
Honestly, the "spun taffy" part is what trips people up. Most folks think they’re just eating dry peanut butter. They aren't.
What you're actually biting into is a highly engineered aerated candy. It’s basically a honeycomb structure made of sugar and corn syrup that has been folded—dozens and dozens of times—with roasted peanut butter. This creates those microscopic layers that shatter when you bite them. It’s why it feels like a cracker but tastes like a confection.
The Weird History of the Butterfinger Name
Back in 1923, Otto Schnering, the founder of the Curtiss Candy Company, needed a follow-up to his massive success with Baby Ruth. He didn't just hire a marketing firm. He ran a public contest. A "butterfinger" was actually a common slang term back then for someone who was clumsy—specifically athletes who couldn't hold onto a ball. It’s kinda ironic that a candy bar named after dropping things became one of the most "un-droppable" brands in American history.
To get the word out, Schnering literally dropped Butterfingers out of airplanes. He used a fleet of 40 planes to shower cities across the United States with candy bars attached to tiny parachutes. Imagine walking down the street in Chicago in the twenties and getting hit in the head by a falling brick of chocolate and spun taffy. That's how you build brand loyalty before the internet existed.
How Spun Taffy Actually Works (The Science of the Snap)
You can't just mix peanut butter and sugar and get that texture. It doesn't work that way. If you try it at home, you’ll just get a gritty paste or a hard rock.

The secret is the temperature and the "pulling" process. The sugar base is cooked to the hard-crack stage. This is the same stuff used for lollipops. But while it’s still pliable, it's stretched and aerated. This is the "spun" part. When you incorporate the peanut butter into this molten sugar, you’re creating a laminate. Think of it like a croissant, but instead of butter and dough, it's peanut butter and sugar-glass.
Why it sticks to your teeth
Because the sugar is basically a glass, it’s hygroscopic. That’s a fancy way of saying it loves water. As soon as it hits the saliva in your mouth, it wants to dissolve and turn back into a sticky syrup. This is why the "crispy" part quickly turns into "cement" on your molars. It’s a feature, not a bug. It forces the flavor to linger.
The Great Recipe Change of 2018
In 2018, Ferrero bought the brand from Nestlé. They decided to mess with the formula. People lost their minds.
The "Improved" Butterfinger launched in early 2019 with a focus on higher-quality ingredients. They started using Jumbo Runner peanuts from the South, dropped the hydrogenated oils, and cut out the TBHQ (a preservative) and the artificial colors like Red 40 and Yellow 5. If you look at an old Butterfinger, the center is a weird, radioactive orange. The new ones are more of a natural, earthy tan.
Some fans hated it. They missed the chemical tang of the old-school bar. Others appreciated that it actually tasted like real peanuts for the first time in decades. The texture changed slightly too—it became less "sandy" and a bit more "snap-heavy." It's still a candy bar with crispy peanut butter and spun taffy at its core, but it's a more "adult" version of the childhood classic.

The Forgotten Competitors
Butterfinger isn't the only player in the crispy-spun-peanut-butter game, though it's the loudest.
- The 5th Avenue Bar: Produced by Hershey, this is the sophisticated cousin. It’s crunchier, uses a different grade of chocolate, and originally came with two almonds on top (though they ditched the almonds years ago). It’s harder to find but has a cult following.
- The Clark Bar: This is the OG. It predates Butterfinger. It’s had a rough ride, changing owners more times than a used Honda. After Necco went bankrupt, the Clark Bar was saved by Boyer Candy Company (the folks who make Mallo Cups). They actually had to spend months figuring out how to get the machines to make the "crunch" right again because the original recipe was so finicky.
- Zagnut: If you hate chocolate, this is your champion. It’s the same crispy peanut butter center but coated in toasted coconut instead of cocoa. It’s basically a Butterfinger that went to the beach.
What Most People Get Wrong About the Nutrition
Look, nobody's eating these for their health. But there’s a weird nuance to the satiety of a crispy peanut butter bar.
Because of the high fat content from the peanuts mixed with the simple sugars of the taffy, you get a massive glucose spike followed by a slower burn from the protein. It’s not "healthy," but compared to a pure sugar candy like Skittles, it’s going to keep you full for significantly longer. A standard Butterfinger has about 250 calories and 10 grams of fat. It also has about 2-3 grams of protein, which isn't much, but it’s more than you'll get from a bag of gummy bears.
How to Bake With It (The Pro Move)
The best way to eat a candy bar with crispy peanut butter and spun taffy isn't actually out of the wrapper. It’s in a cookie.
The heat of an oven does something strange to the spun taffy. It doesn't fully melt; instead, it sort of caramelizes. If you chop up a Butterfinger and fold it into a standard chocolate chip cookie dough, the shards create these little pockets of "toffee-peanut" crunch that stay crispy even after the cookie cools.

Pro tip: if you're using them for a topping on ice cream, freeze the bar first. Then, hit it with a heavy object while it’s still in the wrapper. It shatters perfectly into uniform bits rather than turning into a smeared mess.
The Culture of the Crunch
Bart Simpson basically saved this candy category in the 90s. The "Nobody better lay a finger on my Butterfinger" campaign ran for over a decade. It’s one of the most successful pairings of a fictional character and a snack food in history. It cemented the idea that this specific texture was worth "protecting."
But beyond the commercials, the appeal lies in the sound. Food scientists call it "acoustic bolus." It’s the study of how the sound of food in your mouth affects your enjoyment. The high-pitched snap of spun taffy sends a signal to your brain that the food is fresh and high-energy. We are biologically hardwired to like things that crunch like this.
Why We Can't Get Enough
The reality is that "crispy peanut butter" is a texture that shouldn't exist in nature. It's a miracle of industrial food processing. It’s a delicate balance of fat and sugar that requires precise machinery to pull and fold.
If you're looking to really appreciate the craft, go find a "fresh" Clark Bar from the Boyer factory in Pennsylvania or try the updated Ferrero-era Butterfinger side-by-side with a 5th Avenue. You'll notice the 5th Avenue is denser, while the Butterfinger is more aerated. The difference is all in how much air was spun into that taffy.
Actionable Next Steps
- Check the Date: Spun taffy is sensitive to humidity. If you buy a bar that's close to its expiration date, the sugar starts to absorb moisture and the "crispy" turns into "chewy." Always grab the bar from the back of the shelf.
- Try the Freeze Test: Put your next crispy peanut butter bar in the freezer for two hours. It changes the "shatter point" of the spun taffy and makes the peanut butter taste more intense.
- The DIY Version: If you want to see how the "layers" work, look up a recipe for "Honeycomb Candy" or "Sea Foam." Once you master that, try folding in warm peanut butter. It’s a mess, but you’ll finally understand why these machines are so expensive to maintain.
- Pairing: Pair a crispy peanut butter bar with a sharp, cold glass of whole milk or a bitter black coffee. The fat in the milk helps wash away the sticky taffy, while the coffee cuts through the intense sweetness.
The world of candy changes every year—trends come and go, and everyone is obsessed with "low sugar" right now—but the engineering behind a candy bar with crispy peanut butter and spun taffy is a permanent fixture of the American palate. It's a messy, loud, sticky masterpiece.
