Japanese Jelly Coffee Recipe — 3 Infused Ways to Try It

This Japanese jelly coffee recipe takes your love of coffee to a whole new level — and with an infused twist, it becomes the ultimate cannabis-friendly treat. Fordee walks through the full process, from brewing the jelly base to choosing your infused topping, in this must-try recipe from Herbistry420.

Japanese Jelly Coffee Recipe: What Is It?

The Japanese jelly coffee recipe (also called coffee jello or kohii zeri) is a popular Japanese dessert drink where brewed coffee is set into a jiggly gelatin block, then topped with milk, cream, or condensed milk. It’s refreshing, lightly sweet, and surprisingly easy to make at home — especially if you swap in infused cream or milk for a cannabis-infused version.

Fordee discovered this gem from a friend and immediately saw the infusion potential. The best part? The cannabis infusion happens in the topping, not the jelly itself, making dosing simple and predictable.

Japanese Jelly Coffee Recipe — 5 Ingredients You Need

The base Japanese jelly coffee recipe is surprisingly minimal:

• 2 cups (500 ml) of liquid — brewed espresso, strong coffee, or instant coffee (2–4 tbsp in 500 ml water)
• 1/3 cup (67 g) brown sugar — can be reduced or omitted if you prefer unsweetened
• 2 tsp (6.6 g) unflavored gelatin powder
• Optional: a dash of vanilla extract for extra depth
• Infused topping of choice: infused milk, infused heavy cream, or infused condensed milk

How to Make This Japanese Jelly Coffee Recipe Step by Step

1. Brew your coffee. Use espresso (about 1 cup) plus 1 cup water, or make 2 cups of strong instant coffee. Espresso gives a richer, better flavor than instant — highly recommended.
2. Combine in a pot. Add the 500 ml of coffee liquid to a pot over medium heat. Add the brown sugar and gelatin, stirring to combine.
3. Bring to a boil. Heat just until everything dissolves — you’re not reducing it, just making sure the sugar and gelatin fully incorporate.
4. Add vanilla. Stir in a dash of vanilla extract at this stage if desired.
5. Pour into your serving glass. Fill the glass close to the top. Let it cool slightly before placing in the fridge (thin glass can crack with sudden temperature changes).
6. Refrigerate 3–6 hours until fully set. The jelly should hold its shape when you tilt the glass.
7. Add your infused topping. Pour infused condensed milk, milk, or heavy cream on top. Add whipped cream and a few espresso beans for presentation. Mix and enjoy!

3 Ways to Infuse Your Japanese Jelly Coffee Recipe

The infusion in this Japanese jelly coffee recipe goes into the topping, not the jelly base — which makes dosing precise and easy:

1. Infused condensed milk — Rich, sweet, and THC binds exceptionally well to the fat content. A small drizzle goes a long way. Best for those who want a strong, indulgent dose.
2. Infused heavy cream — High fat content makes it an ideal carrier for THC. Pour it over the jelly like a classic Japanese coffee shop would. Smooth and luxurious.
3. Infused whole milk — A lighter option. Use cannabutter-infused milk or cannabis-steeped milk for a milder effect. Great for lower-dose sipping.

Pro tip from Fordee: You could also add lecithin with a tincture or oil directly into the jelly layer, but infusing the topping is easier and just as effective — THC binds beautifully to fat-rich dairy.

Japanese Jelly Coffee Recipe Tips and Tricks

• Espresso beats instant coffee — The flavor depth is noticeably better. If you have a machine, use it.
• Use a thick glass or ramekin — Thin glassware can crack when hot liquid is poured in. Let the mixture cool slightly before refrigerating.
• Sheet pan method — Pour into a flat pan, let it set, then scoop out chunks into a glass and pour infused milk over the top. Great for a chunkier texture.
• This is not a diet drink — Between the condensed milk, whipped cream, and coffee jelly, this is a full-on dessert experience. Worth every calorie.
• No rush — Let it set the full 5–6 hours. The longer it sets, the firmer and cleaner-tasting the jelly.
