Creating this Agar-Agar Rainbow Jelly Cake always brings a smile to my face, especially thinking about the first time I attempted it for a summer barbecue. The vibrant colors of the jellies reflect the joy and energy of a sunny day, with each layer teasing the palate with its fruity essence. As I prepped the ingredients, I could already hear the laughter of friends and the sizzling of the grill. That day was less about the dish being perfect and more about the joy it brought to everyone gathered around. It's a dessert that transforms any gathering into a colorful celebration.

The first time I served this jelly cake, there were kids running around and adults reminiscing about their childhood favorites. I still remember the delighted gasps as they cut through the rainbow layers, revealing that beautiful spectrum. The laughter echoed around the kitchen, mixed with the clinking of spoons against the bowls of untouched dessert. It was one of those moments that solidified how food can unify and create joy, no matter the age or background. Seeing everyone enjoying their slices made all the effort feel infinitely worthwhile.

Ingredients

  • 2 liters water: This forms the base of your jelly, ensuring it sets beautifully and holds its vibrant color.

  • 400 g granulated sugar: Crucial for sweetness, it balances out the fruit flavors you've chosen.
  • 1/2 teaspoon vanilla extract: This adds a warm depth to the jellies, enhancing the sweetness perfectly.
  • Gel food coloring: Opt for gels instead of liquids for the most vibrant hues.
  • 1/2 cup fruit juice per color: Optional, but it brings a delightful natural flavor to each layer that's worth the splurge.
  • 400 ml coconut milk: This rich, creamy layer tops off the jelly with its lusciousness.
  • 4 g agar-agar powder: Used again for the coconut cream, it ensures your topping sets nicely.
  • 40 g granulated sugar: A little sweetness to balance the richness of the coconut milk.

Components

Jelly Layers

01 2 quarts water
02 2 tablespoons agar-agar powder
03 2 cups 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)

Coconut Cream Layer

01 1 3/4 cups full-fat coconut milk
02 1/2 tablespoon agar-agar powder
03 1/5 cup granulated sugar
04 Pinch of salt

Directions

Phase 01

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

Phase 02

Divide and Color Jelly: Evenly divide the hot agar-agar solution into six bowls (keep warm 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.

Phase 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.

Phase 04

Prepare the Coconut Cream: In a clean saucepan, combine 1 3/4 cups of coconut milk, 1/2 tablespoon of agar-agar powder, 1/5 cup of sugar, and a pinch of salt. Stir well and bring to a boil; simmer for 2–3 minutes until agar-agar dissolves.

Phase 05

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

Phase 06

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