This question came up when the TikTok Starbucks Frappuccino hack went viral.

Starbucks weighed in and tried to tell people not to put glass in the freezer because it could crack.

Instead, Starbucks suggests pouring the chilled drink over ice or shaking the drink with ice in a cocktail shaker, then pouring into a chilled glass.

No. That’s a big no. Hard stop. The end.

But also, just so we’re clear. No.

You should keep bottled Starbucks Frappuccino, or in our case copycat Starbucks Frappuccino, in the freezer for two hours. That’s all.

Keeping it overnight runs the risk of the glass bottle freezing.

But, even more than that, the drink will just get stuck in the bottle if you freeze it too long. And then you have to figure out a way to defrost it.

You could defrost it in the fridge, but that will take forever. You could also defrost it on the counter, but not really because you don’t want dairy sitting out for that long.

So just remember to take the glass bottle out of the freezer after two hours. Or heed Starbucks’ warning and don’t put it in the freezer at all.

You can use any brand of coffee in this copycat Starbucks Frappuccino recipe. Plain coffee is best. You can use a flavored coffee in this copycat recipe if you want, but we don’t. It ends up being too many conflicting flavors if you decide to add syrup as well.

A dark coffee works better in this than a breakfast blend because you’ll get a stronger coffee flavor when you eventually do drink it. Which is good because the flavor will mellow when you add the creamer and again when you drink it when it’s icy.

So, if you start with a dark coffee, you’ll have more of a coffee taste in the final Frappuccino, rather than a mellow taste like you’ll get if you use a light roast.

But if that’s what you like best, go for it.

Personally, I think vanilla flavored creamer adds a sweetness and aids in the consistency of the drink overall, but it doesn’t add that much flavor.

So, I wouldn’t suggest changing the flavor of the creamer.

However, if you want to flavor this frappuccino, use flavored coffee syrup.

A coffee syrup works better in a cold drink than in a warm one. So, you’ll want to add the flavored coffee syrup after the frappe mixture has cooled in the fridge but before it goes in the freezer.

Since the copycat Starbucks Frappuccino recipe has a dairy product (creamer), it should be kept in the fridge in an airtight container. It will last about a week in the fridge.
