🥄 What Makes Costco Butter Different From Regular Grocery Store Brands?
The answer lies in two things:
1. Higher Fat Content
Most American butters are required to contain at least 80% milkfat .
But Costco’s Kirkland butter? It often tests at just over 80% — which may not sound like much, but in baking and frying…
That small difference matters.
More fat = flakier pie crusts
Better caramelization when searing
Richer mouthfeel in baked goods
And yes, it actually melts better too.
2. Clean Ingredients List
No unnecessary fillers.
No artificial flavors.
Just:
Pasteurized cream, salt (in the salted version), and cultures.
This simplicity makes it ideal for:
Baking delicate pastries
Making homemade compound butter
Spreading on warm sourdough without guilt
In an age where ingredient transparency is everything…
That’s a big deal.
🧁 Why Bakers Love Costco Butter (Even Over Designer Brands)
Bakers aren't known for cutting corners — they’re picky about their fats.
So when top-tier pastry chefs and home bakers alike started swearing by Costco butter…
We knew something was up.
Here’s Why It Works So Well For Baking:
Smooth texture
Easy to cream into dough or frostings
Consistent temperature
Comes cold and stays firm — great for pie crusts
No additives
Keeps cookies crisp and cakes light
Affordable luxury
Taste like higher-end butter for less money
Many say it performs just as well as imported European-style butters — minus the fancy label and price tag.
🧑🍳 Real Talk from Home Cooks Who Swear By It
“I use it for everything — laminated dough, mashed potatoes, even garlic bread,” says Julia M., a regular Costco shopper and avid baker.
“It spreads smoothly, browns evenly, and tastes clean and rich. I honestly don’t see the point in paying double for another brand.”
Others echo similar sentiments:
“Better than store-brand butter.”
“I use it for frosting and it doesn’t separate.”

And perhaps most impressively:
Some people buy it specifically to freeze and keep on hand for holiday baking — because once you find a good butter…
You don’t let go.
