Ingredients
- 5 1/2 cups water
- 3 Tbsp agar agar powder
- 1 1/2 cups sugar
- 2 tsp vanilla sugar
- 14 oz can coconut milk
Instructions
-
In a medium saucepan, combine the water and agar agar powder. Let the mixture rest for 15 minutes.
-
Over Medium heat, bring the mixture to a gentle boil, stirring frequently to dissolve the powder. When the mixture comes to a gentle boil, add the sugar and vanilla sugar. Combine together until dissolved. Reduce the heat to Low if the mixture is boiling too vigorously. Add the coconut milk and combine well. Skim off any foam and discard. Remove the saucepan from the heat.
-
Pour the hot jelly mixture into a large dish or individual cups and bowls. Skim off any bubbles from the top using a spoon. Let rest at room temperature until the jelly is firm, approximately 1-2 hours. Transfer the dish into the refrigerator and chill for at least 2 hours.
-
To remove the jelly, run a knife around the dish. Invert the dish and tap on the counter to loosen the jelly. Using a wavy knife, cut the Coconut Agar Jelly into bite-sized pieces.
-
Refrigerate any remaining portions. Enjoy within the week.

Notes, Tips & Tricks
- Use a whole packet of agar agar powder which is .88 oz (25 g). Bloom the agar agar powder by combining with room temperature water and letting rest for 15 minutes. You must bring the agar agar solution to a boil to activate the gelling properties. Also be sure to dissolve the agar agar powder completely otherwise the jelly will not set and be gritty.

- The sweetness level of this Coconut Agar Jelly is right in the middle. For a sweeter jelly, similar to what you'd find at a dessert shop, use 2 cups sugar. Use 1 cup sugar for a lightly sweet jelly.
- For more festive treats, add your favorite food flavorings and colorings and use decorative molds, baking cups or any small bowls or cups to make single-serving sizes.

Other Flavors
The next time I make this I’d like to try using chocolate and matcha. If you make this Coconut Agar Jelly recipe using other flavor variation, I’d love to hear about it!
Love your website and YouTube channel! Your recipes are easy to follow and helps me recreate favorite dishes from my Viet upbringing.
When I made it…the layers separated into the coconut layer and a translucent layer. How do you get one uniform layer? What am I doing wrong?
I am.confused.. recipe said 3 tbsp but tips said whole pack of agar? Guess will have to experiment…thanks for the helpful recipe!!
Hi Tamly, the whole pack of agar agar is probably what you would want to use for a yummy result. I’ve tried the whole pack with an additional 1/2 cup of water and my family and friends are very happy with the result.
Hi Trang,
My mother in law gave Bot Rau Cau (ingredient 100% extracted from seaweed without additives). Is this the same as agar agar powder?
Thank you
Tran
yes, it is!
I really like this recipe, especially the one with chocolate flavor and its cute shape which is very popular with children
Hy I really like the jelly that you make, because of its cute shape, I also like the chocolate flavor.
Hi Trang,
My family and I love the Pandan and chocolate flavored jelly. This is so perfect for the hot days. Thank you for your recipe!
Hi Amy,
