Costco’s New $18.99 Jammy Protein Bites Are the PB&J Snack Upgrade Shoppers Can’t Stop Buying

Smash Foods Jammy Protein Bites variety box at Costco

Remember being a kid and smashing a spoonful of peanut butter and jelly straight out of the jars because you couldn’t be bothered to make a sandwich? Costco just turned that entire mood into a snack you can buy by the case. Smash Foods’ new Jammy Protein Bites have landed in warehouses nationwide, and shoppers are already clearing shelves faster than the bakery can restock a rotisserie chicken.

What’s Actually Inside the Box

The Costco variety box packs 16 individually wrapped 1.8-ounce snack packs for $18.99, split between two combos: Sunflower Butter & Strawberry and Cashew Butter & Blueberry. Each little bite is a soft, cookie-like base filled with real fruit jam, and every pack delivers 8 grams of protein and 3 to 4 grams of fiber. They’re gluten-free, Non-GMO Project Verified, and made without artificial gums or stabilizers, which is exactly why parents packing lunchboxes and gym-goers hunting for a post-workout snack are both claiming this one as their own.

It’s basically the grown-up (and toddler-approved) evolution of the fruit snack aisle, minus the ingredient list you can’t pronounce. If you already stock up on protein-packed breakfast finds, these bites slot right into the same rotation for lunch or an afternoon crash-prevention snack.

Why This One’s Going Viral

Costco’s July new-item lineup is stacked with buzzy finds this month, but Jammy Protein Bites stand out because they solve a real problem: most “protein snacks” taste like chalk wearing a costume. Shoppers online are comparing the texture to a soft granola cookie with a jam-filled center, which is a much easier sell than another dry protein bar. It’s the same energy that made Costco’s viral Dill Pickle Mayo take over shopping carts earlier this month — a familiar comfort flavor, reintroduced with a modern twist.

Availability is regional for now, with sunflower and cashew butter combos rotating depending on where you shop, so don’t expect every warehouse to carry the exact same mix. Smash Foods is also rolling out 30-ounce jars of its jams (Very Berry, Cherry Pomegranate, Blueberry and Raspberry) for $9.79, so if the bites sell out before you get there, the jam alone is worth grabbing for toast, yogurt bowls or a PB&J that actually tastes homemade.

Is It Worth the Cart Space?

At roughly $1.19 per pack, these land right in line with other premium Costco snack bars, but the fiber and protein numbers punch above that price point. They’re an easy win for lunchboxes, road trips, or stashing in a desk drawer for the 3 p.m. slump — basically the same grab-and-go logic behind stretching a Costco rotisserie chicken into a week of dinners: one trip, maximum mileage.

Bottom line: if your Costco has these in stock, grab a box before it disappears into someone else’s cart. Between the nostalgia factor and the “wait, this is actually good for me?” surprise, this is shaping up to be one of the sleeper hits of Costco’s July lineup.
