Layering vibrant colors and flavors, the Agar-Agar Rainbow Jelly Cake with Coconut Cream is a celebration on a plate. It bursts with summer’s joyful spirit, reminiscent of sunny afternoons spent crafting desserts with family under a bright blue sky. The simple process of creating colored jelly layers was like being a child again, marveling at how each hue dances in the light. Coconut cream adds a creamy twist, reminiscent of tropical vacations barely remembered. This dessert transforms any gathering into a festive occasion, and every bite is a refreshing reminder of summer bliss.

One of my fondest memories of making this jelly cake was the laughter that filled the kitchen as my little niece tried to mix the colors, accidentally creating a few unique shades. We ended up with a rather chaotic, but equally delightful, rainbow jelly that tasted just as good as it looked. Family gatherings were never quite the same after we introduced this fun and colorful dessert; everyone wanted a slice of my rainbow dream.

Instructions

Prepare the Jelly Base:
Combine 2 liters of water and 16 g agar-agar powder in a large saucepan, bringing it to a boil while stirring until dissolved. Add 400 g sugar and continue stirring until it melts into the mixture, then remove from heat and add vanilla.
Divide and Color Jelly:
Evenly separate the agar-agar solution into six bowls, keeping them warm to avoid setting too soon. In each bowl, mix in drops of food coloring to create a rainbow effect, adding 1/2 cup of fruit juice for extra flavor if desired.
Assemble Layers:
Pour your first colored layer into a cake pan and let it chill for 10–12 minutes until just set. Repeat this process with each color, pouring over the previous layer and letting it chill in between until completed.
Prepare the Coconut Cream:
In a clean saucepan, mix the coconut milk, 4 g agar-agar, 40 g sugar, and a pinch of salt, bringing it to a gentle boil until the agar-agar dissolves. Take care to stir continuously for even consistency.
Top with Coconut Cream:
Once the coconut cream has cooled slightly, pour it over your set jelly layer and let everything cool completely in the refrigerator for at least two hours. This final touch is what brings everything together!
Serve:
To serve, gently loosen the edges of the jelly with a knife and carefully invert it onto a serving plate. Slice and watch guests marvel at the beautiful layers before diving in for a taste.

Ingredient List

Jelly Layers

01 2 liters water
02 16 g agar-agar powder (about 2 tablespoons)
03 400 g granulated sugar
04 1/2 teaspoon vanilla extract
05 Gel food coloring (red, orange, yellow, green, blue, purple)
06 1/2 cup fruit juice per color (optional, for flavor variation: e.g., orange, pineapple, grape juice)

Coconut Cream Layer

01 400 ml coconut milk (full-fat)
02 4 g agar-agar powder (about 1/2 tablespoon)
03 40 g granulated sugar
04 Pinch of salt

Steps

Step 01

Prepare the Jelly Base: In a large saucepan, combine 2 liters of water and 16 g agar-agar powder. Bring to a boil over medium heat, stirring constantly until agar-agar is fully dissolved. Add 400 g sugar and stir until dissolved. Remove from heat, stir in vanilla.

Step 02

Divide and Color Jelly: Evenly divide the hot agar-agar solution into six bowls (you may keep bowls warm set over hot water to prevent setting). Add a few drops of different food coloring to each bowl for a rainbow effect. Optionally, add 1/2 cup of fruit juice to each for natural flavor.

Step 03

Assemble Layers: Pour the first colored layer into a rectangular cake pan (about 9x13 inches). Refrigerate for 10–12 minutes, or until just set (surface should not stick when touched). Gently pour the next color layer over the previous one. Repeat, alternating colors, chilling between each layer, until all colors are used.

Step 04

Prepare the Coconut Cream: In a clean saucepan, combine 400 ml coconut milk, 4 g agar-agar powder, 40 g sugar, and a pinch of salt. Stir well and bring to a boil; simmer for 2–3 minutes until agar-agar dissolves.

Step 05

Top with Coconut Cream: Let the coconut cream cool for 3–5 minutes, then pour gently over the final set jelly layer. Allow cake to set completely in the refrigerator, at least 2 hours.

Step 06

Serve: To release, gently loosen edges with a thin knife and invert onto a serving plate. Slice and serve chilled.
