A firm, no-gelatin vegan Japanese coffee jelly with a coconut cream topping — my go-to Japanese-style dessert for letting go of a heavy day.
☕️ From My Kitchen Before the Rain Clears
A chilled sweetness for letting go
The rainy season is nearly over.
On days when the sky remains heavy and grey, I reach for something light—a cool, gently bitter Japanese coffee jelly.
As the sound of agar simmering blends with the soft patter of rain outside, the thoughts swirling in my head begin to untangle.
When I stir in the coffee, the aroma wraps around me, and soon, even the things I had been overthinking quietly dissolve.
Later, when the jelly has set, I spoon a silky ribbon of coconut cream over it—and with the first bite, the weight I had been carrying seems to vanish too.
I call it: Coffee Jelly for Letting Go.

🧂 What Is Agar (Agar Agar)?
Agar is a plant-derived gelling agent made from red seaweed — the standard vegan substitute for gelatin, especially in Asian desserts.
In English, it's called agar or agar agar; in Japan, it's kanten (寒天). Unlike gelatin, it sets firmly at room temperature and holds its shape even on hot summer days.
Set with agar, this coffee jelly has a soft, delicate texture — more tender than traditional firm anmitsu kanten cubes, yet firmer than a gelatin-set jelly.
One thing to watch for if you're shopping in Japan: there's a separate product also labeled "アガー" (agar) sold there, but it's actually made from carrageenan and locust bean gum — not the same as kanten.
It sets softer and at a lower temperature, so it won't give you the same texture here. For this recipe, look for 粉寒天 (kanten powder) or agar agar powder, not アガー.
Powder? Flakes? Sticks?
Agar comes in a few different forms, and the amount you need changes depending on which one you use.
- Powder — the most concentrated and easiest to measure. This is what I use for this recipe because it dissolves quickly and gives consistent results.
- Flakes — coarser and less concentrated, so you'll need about 3x more than the powder amount.
- Sticks (bou kanten / 棒寒天) — the traditional Japanese form. They need to be soaked in cold water, squeezed dry, and then dissolved. A standard stick is roughly equivalent to about 1 tablespoon of agar powder, though sizes vary by manufacturer.
I've only ever used kanten powder in my cooking — it's easy to find and simple to handle.
🥥 Ingredients
- Instant coffee – 5 g (feel free to increase for a bolder taste)
- Kanten powder (agar agar) – 1 tsp (2 g)*
- Water – 400 ml
- Coconut cream or coconut milk – to serve
- Powdered beet sugar – to taste (for the cream; any light-colored sweetener works)

📖 How to Make
Just a few minutes of hands-on time — enough to soften your thoughts and let go.
- Make the Jelly:
In a saucepan, whisk together agar powder and water. Bring to a boil, then reduce heat and simmer for 2 full minutes, stirring often.
- Add the Coffee:
Remove from heat. Add instant coffee and stir until completely dissolved.
- Pour & Chill:
Pour into molds or a container. Let cool slightly, then refrigerate for 1–2 hours until fully set.
- Sweeten the Cream:
Mix coconut cream with powdered beet sugar until smooth. Spoon generously over the chilled jelly.
🕊 My favorite ratio is 1 tablespoon coconut cream : 1 teaspoon sugar.
🥄 Tools
- Small saucepan – for dissolving agar and heating the liquid
- Whisk – for mixing agar and preventing clumps
- Measuring spoons & scale – to accurately measure agar, coffee, and sugar
- Glass cups or molds – to set and serve the jelly
- Spoon or spatula – for pouring and layering coconut cream
- Mixing bowl – for sweetening and whisking the coconut cream
- Refrigerator – for chilling and setting the jelly
🫙 Storage Notes
- Keeps for 2–3 days in an airtight container in the fridge.
- Add coconut cream just before serving — if it sits too long, the jelly can release a little water and the cream loses its clean layer on top.
📓 From My Kitchen Notes
- For a sweeter finish, stir sugar in along with the coffee in Step 2 — taste as you go, since this softens the bitterness and sourness of coffee slightly.
- If you prefer a softer jelly, reduce agar to 1g per 400ml water.
📚 FAQ & Tips
Traditional coffee jelly usually isn't — it's typically set with gelatin and topped with whipped cream or condensed milk. This version swaps in agar powder and coconut cream instead, so it's fully plant-based.
Yes. Coffee is added off the heat to preserve its aroma, so if you're using brewed coffee instead of instant, brew it separately rather than boiling it with the agar. Make sure the total liquid still adds up to 400ml — for example, 200ml brewed coffee + 200ml water (with kanten powder).
☕ A tip from my old coffee shop days:
every summer we sold coffee jelly made with gelatin, and the secret to a flavorful jelly was brewing the coffee about twice as strong as usual.
Since this recipe dilutes the brewed coffee by half (200ml coffee + 200ml water), you'll want to brew it about 4x your usual strength to keep that same depth of flavor.
You can add sugar to the jelly itself to mellow the bitterness, or sweeten only the coconut cream.
Powdered beet sugar is gentle in color and dissolves easily—perfect for this.
Usually due to undercooked agar. After boiling, make sure to simmer it for 2 full minutes to activate its setting power.
Reduce agar to 1g per 400ml of liquid. The result is a more delicate, jiggly jelly.
Yes, though gelatin sets softer and can't be boiled — skip the simmering step, and follow the package instructions for the right amount.
