11 Costco Snacks Members Always Stock Up On

Costco is famous for bulk buys and unbeatable deals, but some products stand out above the rest. The snack aisle, in particular, has a cult following. Whether you are looking for quick protein, crunchy treats, or something to keep the kids happy, Costco’s snack section has options members grab again and again. From pantry staples to health-conscious bites, these snacks combine value with taste, proving why they are so often tossed into overflowing carts. Here are 11 member-favorite Costco snacks you will always see stocked up in bulk.

Kirkland Signature Protein Bars

Costco’s Kirkland Signature protein bars come in different lines: pick the box that fits the goal. The higher‑protein bars (e.g., Chocolate Chip Cookie Dough, Chocolate Peanut Butter Chunk) deliver about 21–22 g protein with low sugar and great value, ideal for gym bags and busy days. The Chewy Protein Bar line is closer to ~10 g protein and more snack‑leaning. Clarity on the SKU prevents mix‑ups and keeps expectations on taste and macros aligned.

Pirate’s Booty Aged White Cheddar

Pirate’s Booty is a light, baked rice‑and‑corn puff dusted with aged white cheddar, and it’s gluten‑free. Costco sells oversized bags and handy multipacks, making lunchbox portioning simple. Parents like the airy crunch as a lighter alternative to fried chips, and kids finish them fast. Value pricing and family‑friendly flavors explain why they disappear quickly. Multipack formats make stocking up straightforward and cost‑effective.

Kirkland Signature Trail Mix

Costco’s Kirkland Signature Trail Mix has long been a bulk-buy essential. Packed with peanuts, almonds, cashews, raisins, and chocolate candies, it hits the sweet-and-salty balance that makes trail mix irresistible. Available in giant resealable bags or individual packs, it works for hiking trips, road snacks, or quick afternoon energy boosts. Nuts add healthy fats and protein, while raisins and chocolate give just enough sweetness. Its consistent quality and unbeatable value make it a staple across households. Year after year, trail mix remains a Costco best-seller and crowd-pleaser.

MadeGood Granola Minis

For allergy‑aware households, MadeGood Granola Minis are free from common allergens and produced in an allergen‑controlled facility, making them popular for school lunchboxes. Bite‑size clusters offer whole grains with “hidden” vegetables for a small nutrition boost. Individually wrapped pouches simplify packing and portion control, and buying in bulk at Costco improves affordability compared to grocery packs.

Kirkland Signature Roasted Seaweed

Light, crisp, and salty, Kirkland’s roasted seaweed is a lunchbox standby. Costco’s USDA Organic, sesame‑seasoned multipacks deliver minimal calories per serving and strong value over smaller grocery packs. Adults reach for them as a low‑carb chip swap, and kids love the papery crunch. Multipacks tuck neatly into pantries and desks, reinforcing why this simple, flavorful snack stays on members’ bulk lists.

Brownie Brittle

Brownie Brittle offers thin, crisp shards with rich cocoa flavor for a lighter‑feeling crunch than a traditional brownie. It’s still a sweet treat, but the texture satisfies chocolate cravings without feeling heavy. Costco’s resealable bulk bags enhance value and shareability—though many admit it vanishes fast. Families and chocoholics alike keep it on hand for an easy dessert‑ish snack.

Whisps Parmesan Cheese Crisps

Whisps Parmesan Cheese Crisps are made from 100% baked cheese: crunchy, savory, low‑carb, and keto‑friendly. They work as a stand‑alone snack or as a salad and soup topper. Costco’s large bags stretch further than grocery sizes, delivering better value per ounce. With straightforward ingredients and solid protein, they appeal to label‑readers and casual snackers alike, explaining their repeat‑buy status.

Nature Valley Sweet and Salty Nut Bars

These bars balance chewy granola and roasted nuts with a peanut butter or yogurt‑style coating. They feel like a treat while still offering quick energy for lunchboxes, travel, or coffee‑break snacks. At Costco, bulk packs are cost‑effective and keep pantries stocked. They’re not “high‑protein” like protein bars, but the taste, texture, and convenience keep members coming back for more.

Kirkland Signature Mixed Nuts

Kirkland’s oversized jars of mixed nuts deliver freshness, variety (often cashews, almonds, pistachios, and pecans), and strong value. Packed with protein, fiber, and healthy fats, they satisfy between meals and double as an easy entertaining staple. The resealable jar format makes them convenient to store and serve, which, combined with price per ounce, explains their enduring popularity in carts.

Welch’s Fruit Snacks

Welch’s Fruit Snacks are lunchbox‑friendly and kid‑approved, made with fruit purée for familiar, fruity chew. They’re a sweet snack first and foremost, prized for convenience and portion‑controlled packets on road trips and school days. Costco multi‑box deals improve value versus grocery chains, making them an easy, repeat buy for households with kids who favor chewy, fruit‑forward treats.

Hippeas Organic Chickpea Puffs

Hippeas have become a rising favorite in Costco’s snack lineup. These airy, crunchy puffs are made from chickpeas, giving them more fiber and protein than traditional corn-based puffs. Flavored with options like white cheddar or sriracha, they satisfy both salty cravings and health-conscious snackers. Parents like them as a lunchbox option, while adults enjoy them as a lighter alternative to chips. Costco’s bulk packaging makes them more affordable than buying smaller bags individually. Their balance of taste, texture, and nutrition has made them a fast-growing member favorite.
