Whether you're a fan of whipped coffee, looking for something new to try or maybe because you don't have (or don't like) instant coffee, you're going to want to get to know the new internet sensation: kori-kohi coffee. The drink, which was popularized by UCC Coffee Shops in the Philippines and is now blowing up online, is shockingly simple: It's essentially just warm milk poured over coffee ice cubes. You can add a little sugar syrup if you want.

It's so simple, in fact, that I admit I was a little skeptical about how good kori-kohi could be when I first heard about it. But after trying it out, I am a total convert: I can honestly say this is one of the best iced coffees I've ever had (and I've had kind of a lot of iced coffee). The magic is the coffee ice cubes—while regular iced coffee gets watered down and more insipid-tasting as you drink it, this coffee gets better, so your last sip is the most delicious. Here's how to do it at home.

How to Make Kori-Kohi Iced Coffee at Home

1. Brew some coffee

Start by brewing a pot of coffee at least eight hours before you want your coffee treat. (Try not to drink the coffee right away—this was hard for me.) I used my pour-over but you can use any kind of coffee, including instant. I think this would be particularly good with cold brew.

2. Freeze your coffee

When the coffee has cooled slightly, pour it into an ice cube tray and freeze until solid (at least 8 hours).

3. Put the ice cubes in a glass

Crack those cubes out of the tray and stick them in a glass. Choose a sturdy pint glass like the one shown here—and make sure not to add milk that's too hot in the next step—to avoid potential breakage. A mason jar, heatproof coffee cup or stainless-steel pint cup would also work well. I used a full tray's worth of coffee cubes in my glass.

4. Pour warm milk over the cubes, stir and enjoy!

Heat some milk on the stovetop or microwave until warm but not boiling. One cup was the perfect amount for me. Pour the milk over the coffee cubes and get ready for a little coffee nirvana. The warm milk slowly melts the cubes, giving you the perfect, rich-tasting iced coffee. Classic kori-kohi coffee also comes with sugar syrup for pouring over the coffee. If you want to sweeten your coffee, you can make a simple syrup by heating equal parts sugar and water together on the stovetop or in the microwave until the sugar dissolves, then cooling. However, I found it easier to simply add some sugar to my warm milk before pouring it over the coffee cubes (you could also sweeten the coffee before freezing).

If, like me, you find you want to constantly stir the coffee while drinking, a metal straw is perfect—you can get a pack of 4 for $7.99 from Williams Sonoma.
