Ingredient Breakdown
- 1 cup Boiling Water

- Thickened Cream / Heavy Cream
- Garnishes
How to Make Easy Japanese Coffee Jelly
Mix It Up: In a large jug, combine your instant coffee, gelatin powder, brown sugar, and boiling water. Whisk everything together until the sugar has dissolved and make sure there are no gelatin granules stuck at the bottom. It should be nice and smooth!
Cold Water Combo: Now, pour in that cold water and whisk it all up again. You’ll see the coffee jelly start to come to life!
Container Time: Pour the mixture into either cute little dessert cups or a larger glass dish if you plan on cutting it into cubes later. Give it a little tap on the counter to remove any air bubbles, you want a nice smooth finish.
Fridge It: Place it in the fridge for at least 3 hours to set. Don’t worry if it still feels a little warm when you pop it in; that cold water we added helps it cool off fast!
Serve and Savor: Once set, if you used a larger dish, cut the jelly into cubes. Scoop them into serving dishes or leave them be. Just remember to add any optional garnishes like whipped cream, mint leaves, or a drizzle of condensed milk right on top to make it visually stunning and totally tasty!
