Coffee jelly is a dessert made from black coffee and gelatin. Once common in British and American cookbooks, it gained popularity in Japan in the 1960s after a Japanese chain coffee shop branch first made the concoction. Called kohii zerii in Japanese, it is now found in most restaurants and convenience stores throughout the country.

Coffee jelly is very easy to make: Sweeten strong coffee while heating it, then add a mixture of powdered gelatin and water and let it set up in the fridge. This recipe creates coffee jelly that is light and not too sweet, though you can adjust the sweetness to your liking. It's perfect for dessert, especially following a Japanese dinner in place of or alongside a cup of coffee. It's known as a refreshing Japanese summertime treat, but feel free to enjoy it all year long.

"Easy to make and rather tasty, this coffee jelly recipe is fun. You really do want strongly brewed coffee because the flavor is much lighter than you’d expect, and I’d probably sweeten it a bit more. Served in stemware, it will make a fabulous finish for a dinner party." —Colleen Graham

  • This recipe requires strong coffee; if you can, use espresso as it will impart both rich flavor and wonderful aroma. Alternatively, brew coffee with a drip cone, moka pot, or French press as these nonelectric brewers produce a richer coffee than the standard drip machine.
  • Leftover coffee jelly will keep in the fridge for up to two days when stored in an airtight container.

Recipe Variations

  • If you'd like sweeter coffee jelly, try an extra tablespoon of sugar and taste the coffee mixture (adding more if needed) before mixing it with the gelatin.
  • To make this recipe vegetarian, use agar-agar instead of gelatin.
  • Instead of cutting into cubes, make individual servings by pouring the liquid mixture into small bowls or cups.
  • Create a coffee experience by placing the cubes in a mug and adding some sweetened heavy cream or condensed milk.

Is Coffee Jelly healthy?

When enjoyed in moderation, coffee jelly can be a nutritious dessert or snack—or at least one of the healthier options. This recipe contains a small amount of sugar, and both coffee and gelatin have health benefits. For instance, coffee contains essential nutrients, while the collagen in gelatin may help the skin, hair, and joints. Both ingredients are noted for improving cognitive function, so collectively, they could be good for your brain, too.
