Costco’s ice cream sandwiches are cold, creamy treasures tucked behind the freezer doors—and yes, they’ve earned a serious fanbase. With flavors ranging from nostalgic classics to wild new twists, there’s a lot to love… and a few that fall a little flat.
Not every sandwich hits that magic balance of chewy, sweet, and bold. This list ranks 10 of the most popular flavors from forgettable to freezer-worthy.
10. Cookies & Cream
This one promises creamy cookie bliss but delivers something closer to plain vanilla with crumbled bits. The cookie presence feels more cosmetic than flavorful.
The base is smooth, but the lack of rich cocoa crunch leaves it feeling unfinished. It’s not bad, just underwhelming for such a beloved combo.
9. Mint Chocolate Chip
Fans of minty treats may still find this version too sharp, veering closer to toothpaste than dessert. The chocolate bits help, but barely.
The texture’s creamy, but the flavor feels unbalanced. A cooling bite that lacks the cozy finish mint lovers crave.
8. Strawberry Shortcake
There’s a hint of jammy fruit, but not enough to offset the artificial edge. The sandwich feels light but lacks punch.
More real strawberry would make a difference here. It’s sweet and pink, but the flavor doesn’t linger.
7. Peanut Butter Chocolate
This combo should be unstoppable, yet the peanut butter fades fast behind the bold chocolate. Rich? Yes. Memorable? Not quite.
A stronger nutty swirl would elevate it. As-is, the chocolate steals the spotlight, leaving peanut butter in the dust.
6. Salted Caramel
Sweet, buttery caramel ice cream nestles between chocolate wafers, but the “salted” part barely registers. It leans dessert without the contrast.
Still creamy and indulgent, just not as punchy as promised. A gentle crowd-pleaser that plays it safe.
5. Vanilla Bean
There’s real vanilla warmth here, speckled with bean flecks and tucked between soft cookies. It’s familiar, clean, and well-made.
No surprises, no bold moves—just quality ingredients done right. For purists, it’s the gold standard of simplicity.
4. Chocolate Fudge Brownie
This one means business. Dense chocolate ice cream with thick brownie chunks delivers deep flavor and irresistible texture in every bite.
The sandwich tastes like an ice cream shop creation. It’s bold, rich, and feels like dessert with a capital D.
3. Mocha Swirl
The coffee flavor is strong but smooth, weaving through creamy swirls with a touch of sweetness to balance it all out.
It’s perfect for espresso lovers and those who like their dessert with a grown-up twist. Easily one of the most layered and satisfying picks.
2. Birthday Cake
Rainbow sprinkles, frosting vibes, and a smooth cake batter cream come together without the fake vanilla overload. It’s sweet, but not cloying.
Every bite feels like a party. Somehow nostalgic and totally modern all at once.
1. S’mores
Chocolate, toasted marshmallow, and graham cracker flavor come through with stunning clarity. The textures melt together just right.
It tastes exactly like summer by the fire—no flame required. The sandwich to grab before it sells out again.
