Rainbow Agar-Agar Jelly Cake (Print-Friendly)

Silky agar-agar rainbow layers crowned with creamy coconut—dairy- and gluten-free, chilled and ready to serve.

# What You'll Need:

→ Agar-Agar Jelly Layers

01 - 2 tablespoons agar-agar powder (about 16 g)
02 - 900 ml water
03 - 200 g granulated sugar
04 - Food colorings: red, orange, yellow, green, blue, purple
05 - 1 teaspoon vanilla extract (optional)

→ Coconut Cream Layer

06 - 400 ml coconut cream
07 - 200 ml water
08 - 2 tablespoons agar-agar powder (about 16 g)
09 - 100 g granulated sugar
10 - Pinch of salt

# Cooking Steps:

01 - In a saucepan, combine 2 tablespoons agar-agar powder with 900 ml water. Bring to a boil over medium heat, stirring constantly until agar-agar dissolves completely (about 3 minutes). Add 200 g sugar and vanilla extract, stirring until dissolved.
02 - Remove from heat and divide the clear agar mixture into 6 bowls. Add a few drops of each food coloring to create red, orange, yellow, green, blue, and purple.
03 - Pour the red layer into a rectangular or round mold (about 20 cm diameter). Let it cool for 5–8 minutes, until just set but not too firm. Repeat with orange, yellow, green, blue, and purple, allowing each layer to set before adding the next.
04 - In a clean saucepan, mix 2 tablespoons agar-agar powder with 200 ml water and 400 ml coconut cream. Bring to a gentle simmer, stirring well. Add 100 g sugar and pinch of salt, stir until dissolved.
05 - Once the last jelly color has set, gently pour the warm coconut cream mixture over the rainbow layers. Allow to cool to room temperature.
06 - Refrigerate for at least 1 hour or until completely firm. Gently loosen edges and invert onto a serving plate.
07 - Cut into neat slices or cubes. Serve cold.

# Expert Tips:

01 -
  • Each slice looks like a stained glass window and feels like a party trick—even for grownups.
  • Dairy and gluten free, this stunner means no one misses out at the dessert table.
02 -
  • If you try to rush the chilling, the layers will blur or even collapse—slow and steady sets the rainbow right.
  • Pouring on coconut cream that’s too hot can melt your masterpieces below; let it cool a few minutes first.
03 -
  • Clean up spills fast—dried jelly on bowls means extra soaking later.
  • Keeping your agar mixture warm between layers smooths the whole process and prevents clumpy pours.
