You're standing in the candy aisle. You see the standard two-pack. Then you see the King Size. Then, maybe, the Big Cup. But have you ever wondered just how far this obsession goes?
Most people think the "World's Largest" version you buy at the mall is the peak. It isn't. Not even close.
When we talk about the biggest Reese's peanut butter cup, we’re actually looking at a weird split between what you can eat for dinner and what requires a forklift to move. Honestly, the gap between a "big" retail candy and the actual world record is staggering. It’s the difference between a pebble and a mountain.
The 3.25-Pound Monster: The Thanksgiving Pie
In 2021, Hershey’s decided that traditional pumpkin pie was boring. They released the Reese’s Thanksgiving Pie. It was basically a massive, 9-inch diameter peanut butter cup.
No crust. No fluff. Just 3.25 pounds of solid peanut butter and chocolate.
They only made 3,000 of them. They sold out in hours. People were losing their minds on social media because, let's be real, who actually wants a sliver of apple pie when you can have a wedge of a giant peanut butter cup? It remains the largest official "cup" ever sold by the company as a single unit. It’s roughly the size of a standard frisbee but significantly more delicious.

The World Record: A 600-Pound Beast
If the Thanksgiving Pie is a heavyweight, the Guinness World Record holder is a literal titan. In 2016, the Northwest Fudge Factory in Ontario, Canada, shattered the previous record.
They built a peanut butter cup that weighed 603 pounds.
Think about that for a second. That is the weight of a large grizzly bear. They used a massive custom mold and hundreds of pounds of ingredients. To get the texture right, they actually used a peanut butter substitute called WowButter to partner with the brand, but the scale was undeniable. It beat the previous record—a 440-pound cup made in a kiddie pool in Los Angeles—by a massive margin.
- Weight: 603 lbs (273.5 kg)
- Ingredients: 300 lbs of peanut butter center, 300 lbs of chocolate fudge
- Fate: It was chopped up and sold to fans for charity.
Buying the "World's Largest" at Retail
You probably aren't going to commission a 600-pound candy for your birthday. So, what’s the biggest one you can actually walk into a store and buy?
That would be the Reese's 1 lb. Giant Peanut Butter Cups set.

It’s a bit of a marketing trick. The box says "World's Largest," but it actually contains two 8-ounce cups. So, while the total package is a pound, the individual cups are half a pound each. Still, an 8-ounce cup is a beast. It’s about 4 inches wide. Eating one in a single sitting is a feat of strength. Most people end up slicing them like a steak.
The Evolution of the "Big" Cup
Reese’s hasn’t always been about size. For decades, the standard cup was the only way to go. But then the "Big Cup" arrived in 2003. It changed the ratio.
A standard cup is about 0.75 ounces. A Big Cup is 1.4 ounces.
It’s nearly double the thickness. This wasn't just about more candy; it was about the mouthfeel. Some people swear the ratio of chocolate to peanut butter in a Big Cup is superior because the peanut butter is so much more dominant. Lately, they’ve started stuffing things inside them—pretzels, potato chips, even Reese’s Puffs cereal. It’s like a sandbox for candy scientists.
Why We Are Obsessed With Size
There is something visceral about seeing a tiny object made huge. It triggers a weird part of the brain. When H.B. Reese first started making these in his basement in the 1920s, he probably didn't imagine people would be pouring chocolate into swimming pools 100 years later.

But the biggest Reese's peanut butter cup represents more than just a sugar rush. It’s a cultural icon. We want the biggest because the combination of salty peanut butter and sweet milk chocolate is scientifically designed to be addictive. It's that "bliss point" where your brain just gives up and asks for another bite.
Practical Advice for the Giant Candy Hunter
If you're looking to get your hands on a massive cup, don't just buy the first thing you see.
- Check the Weight: Always look at the "Net Weight" on the box. Some "Giant" boxes are just filled with many small cups. You want the one that says "2 - 8oz Cups."
- Watch the Seasonal Drops: The 3-pound pies and the "Super Mountain" varieties usually only appear around November or December. If you see one, grab it. They don't last.
- Storage Matters: A half-pound peanut butter cup is a lot of fat and sugar. If you don't eat it quickly, the peanut butter can get "chalky." Keep it in a cool, dry place—but maybe not the fridge, as that can make the chocolate bloom and turn white.
Honestly, though, if you're going for the record at home, just buy a pie tin, some bulk chocolate, and a few jars of creamy PB. It won't be 600 pounds, but it'll be yours.
Actionable Next Steps:
To find the current largest available retail version, check the "Holiday" or "Gift" section of major retailers like Walmart or Target, or visit the official Hershey’s Store online. If you're looking for the 1lb Giant Cups (two 8oz cups), they are most commonly stocked during the Christmas and Easter seasons. For the true 3.25lb Thanksgiving Pie, keep an eye on the Hershey's website starting in early November, as they typically release limited batches that sell out instantly.
