Perfect Bar Organic Protein Bars from Costco are one of my favorite high-protein snacks to keep stocked in the fridge. They’re organic, made with clean ingredients, and actually taste good—not like those dry, chalky bars I’ve tried in the past.

Costco carries a 12-bar variety pack with two flavors: Peanut Butter and Dark Chocolate Chip Peanut Butter. Both are solid, but the chocolate chip one is definitely my favorite. It tastes like a peanut butter cookie with little chocolate bits mixed in. The original peanut butter is rich and smooth, with that classic nut butter flavor and just the right amount of sweetness from honey.
Taste and Texture
These bars are refrigerated, so they stay soft and chewy. The texture is thick and dense—kind of like cookie dough. They’re sweet but not overly sweet, and the nut butter flavor comes through strong in both versions.

Because they’re so filling, I usually only eat half at a time. A whole bar feels more like a meal replacement than a snack for me. That’s actually why I prefer the Perfect Bar minis, which are much smaller and easier to finish in one go. But even when I split the full-size bar in half, it still feels satisfying.
Why I Keep Buying Them
I love that they’re made with real, organic ingredients and pack in about 15–17 grams of protein per bar. That’s great when I need something quick that’ll actually hold me over for a few hours.
I usually grab one in the afternoon or toss a half into my bag for a snack after errands or a walk. Sometimes I’ll cut one up and pack it in my kids’ lunchboxes too—they’re sweet and soft enough that my kids actually eat them without complaining (which is a win).

Where to Find Them
You’ll find the Perfect Bar Organic Protein Bar Variety Pack in the refrigerated section at Costco, usually near the cold drinks, juices, and pre-made meals. Keep them in the fridge at home too—though they’re totally fine to take on the go for the day.
The box comes with 12 full-size bars: a mix of peanut butter and dark chocolate chip peanut butter flavors.

Final Thoughts
Perfect Bar Organic Protein Bars from Costco are a solid choice if you’re looking for a filling, clean-ingredient snack. The flavor is great, the texture is soft and satisfying, and I love knowing what’s actually in them.
I usually only eat half at a time since they’re pretty big, and I wish Costco would carry the mini size more often. But even with that, they’re still a repeat buy for me—especially the dark chocolate chip peanut butter ones.
⭐️⭐️⭐️⭐️ (4 out of 5 – super tasty and clean, just wish the minis were easier to find)
