Trader Joe’s Cult-Favorite S’Mores Bars Are Back — And They’re Selling Out at $4.99 a Box

Forget the campfire, the bug spray, and the stick that always snaps at the worst possible moment. Trader Joe’s just brought its cult-favorite S’Mores Bars back to the freezer aisle, and shoppers are once again losing their minds over a $4.99 box of six. If your social feed has been full of people cracking open a TJ’s freezer door lately, this is almost certainly why.

What’s Actually in the Box

Each bar stacks three layers: a buttery honey graham cracker crust on the bottom, a rich fudgy brownie in the middle, and a torched marshmallow topping on top that’s meant to mimic that just-off-the-fire char. It’s a frozen dessert doing its best impression of a summer campfire classic, no flame required. Six bars come in a box for $4.99, which pencils out to well under a dollar a bar — the kind of math that makes an impulse grab feel downright responsible.

The bars first showed up a few summers back and have made repeat appearances ever since, and this latest restock is proving just as popular. Fan accounts and TikTok reviewers have been flooding feeds with taste tests, and the verdict is mostly glowing: the brownie layer is the standout, rich and fudgy in a way that holds up even frozen solid, while the toasted marshmallow gives it that nostalgic char flavor a lot of s’mores-flavored snacks miss entirely.

Three Ways to Actually Eat One

Because they’re packaged frozen, you’ve got options, and this is where shoppers get a little divided. Trader Joe’s suggests thawing at room temperature for about two hours for the softest, most s’more-like texture. If you’re impatient (no judgment here), eight seconds in the microwave gets you close to that same gooey payoff in a fraction of the time. And if you want the marshmallow top genuinely toasted and a little crisp, a two- to three-minute stint in the air fryer is the move everyone online seems to be recommending.

“These are delicious! Should I run over there and grab some tonight?” — a shopper reacting to a fan account’s post about the bars

Worth noting: not every review has been a perfect ten. A few longtime TJ’s watchers have pointed out that the graham and marshmallow layers can run a little thin compared to the brownie base, so don’t expect a towering, bakery-style s’more. Think of it more as a fudgy brownie with s’mores flavoring built in, and you’ll set your expectations exactly right.

How This Stacks Up Against TJ’s Other Freezer Aisle Hits

The S’Mores Bars are joining an increasingly stacked freezer section this year. If you loved the swicy crunch of Trader Joe’s Hot Honey Popcorn, or you’ve already cleared out a box of the Raspberry Filled Donuts, the S’Mores Bars slot in nicely as your next freezer staple. And if you’re weighing frozen novelty desserts across stores, it’s also worth putting these up against Costco’s viral 3D Peach and Mango Ice Cream for your next grocery run — both are the kind of frozen treat that makes people stop scrolling and start screenshotting.

Should You Grab a Box?

At $4.99 for six, this is about as low-risk as viral grocery finds get. Even if they’re not your platonic ideal of a s’more, you’re getting six individually portioned brownie-marshmallow bars for less than the price of a fancy coffee. Given how quickly past batches have disappeared from shelves, if you spot them in the freezer aisle on your next Trader Joe’s run, it’s probably worth grabbing a box (or two) before National S’mores Day rolls around again and they vanish for the season.
