Jams at Walmart: Can a Protein-Packed PB&J Take a Bite Out of Uncrustables?

A Classic Reimagined for a New Generation

The frozen aisle at Walmart just got a little more competitive—and a lot more athletic.

This week, Jams, a startup backed by U.S. soccer legend Alex Morgan and NFL stars C.J. Stroud and Micah Parsons, launched its first line of frozen peanut butter and jelly sandwiches in 3,000 Walmart stores nationwide. The product may look familiar—a crustless PB&J with freezer-friendly convenience—but founder Connor Blakley is betting that today’s health-conscious consumers, especially athletes, are ready for a new take on the lunchtime classic.

And he’s not just tweaking the recipe—he’s coming straight for the category leader.

Taking on a Billion-Dollar Behemoth

Smucker’s Uncrustables has long dominated the grab-and-go PB&J space, with J.M. Smucker forecasting over $1 billion in net sales from the brand by fiscal 2026. Walmart shoppers know the blue-boxed staple well. But Blakley believes there’s room for disruption, especially with a generation of shoppers scrutinizing ingredient lists and counting macros.

“No seed oils. No dyes. No artificial flavors or colors. No high fructose corn syrup,” Blakley told CNBC. “And we have the most protein per ounce of any peanut butter and jelly that’s currently on the market.”

Each Jams sandwich clocks in at 10 grams of protein and 74 grams in total weight—beating Uncrustables’ 58-gram build. It’s slightly larger and significantly more functional for gym-goers, student athletes, and active families looking for a clean-label snack that still hits the nostalgia button.

The Locker Room Advantage

It’s a strategic wedge into a surprisingly high-performance space. NFL teams alone reportedly consume over 80,000 Uncrustables annually. The Athletic notes that PB&J sandwiches have become a staple in locker rooms across major leagues, prized for their balance of carbs, protein, and portability. Jams wants to be the next locker room legend—without compromising on nutrition.

The initial lineup includes two core flavors: strawberry and mixed berry. Manufactured in Ohio and Wisconsin, Jams sandwiches will retail at $5.97 per box, slightly higher than Uncrustables’ $4.34 price tag. But for many shoppers—especially Walmart’s growing base of wellness-minded consumers—that $1.63 premium could be worth it for added protein and cleaner ingredients.

David vs. Goliath (In the Frozen Section)

Still, Jams faces an uphill battle.

Smucker’s has spent the last two decades scaling Uncrustables into a powerhouse. A third and largest production facility opened this year in McCalla, Alabama, reflecting the company’s confidence in category growth. With Walmart already its biggest retail channel, Smucker’s has the shelf space, brand trust, and manufacturing might to hold its lead.

But what Jams may lack in scale, it makes up for in cultural currency. Blakley, who dropped out of high school at 17, taste-tested over 250 versions of his PB&J before landing on the final recipe. Now at 26, he’s tapping into a generation that values hustle, health, and hands-on entrepreneurship—values echoed by his athlete investors.

Walmart’s exclusive rollout gives the brand a major visibility boost. It also signals Walmart’s willingness to lean into emerging, functional food startups that resonate with younger shoppers and performance-driven lifestyles.

Final Thoughts

For Walmart suppliers and sellers, Jams’ debut offers more than just a new item in frozen. It’s a case study in how to disrupt a legacy category by zeroing in on unmet needs—higher protein, cleaner labels, cultural relevance—and using Walmart as a launchpad. Whether Jams becomes a staple or a short-lived snack trend remains to be seen, but it’s already proving one thing: even a humble PB&J can be reimagined, rebranded, and rebuilt for today’s high-performance consumer.
