Rainbow Jelly Cake Agar-Agar Coconut (Print Version)

Multi-layer agar-agar jelly in rainbow hues, topped with creamy coconut layer — dairy- and gluten-free, served chilled.

# 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

# How to Make It:

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.

# Additional Tips::

01 -
  • This is your chance to show off bright colors and silky textures with almost no fuss—a secret mood-booster for any dessert table.
  • It’s delightfully light, non-dairy, and refreshingly cool when the weather is just too warm for baking.
02 -
  • I once pulled the jelly too soon and the top layer ran away—always wait until the surface is just set before pouring the next color.
  • Letting the coconut mixture cool down slightly before pouring prevents it from melting your rainbow beneath—a quiet game-changer.
03 -
  • If layers start to set too quickly while coloring, a second or two over low heat brings them back to fluid.
  • Swirl each new layer slowly over the back of a spoon to avoid splatters and preserve those crisp lines.
