Rainbow Jelly Cake with Coconut (Printable View)

Six colorful agar-agar jelly layers topped with creamy coconut—dairy- and gluten-free chilled dessert.

# 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.

# Expert Tips:

01 -
  • Layering the rainbow almost feels like painting, except you get to eat the masterpiece.
  • Unlike most cakes, this dazzling dessert is surprisingly refreshing and won’t leave you feeling heavy.
02 -
  • If each layer isn’t firm enough before adding the next, they’ll blur together—embrace the learning curve and test with a gentle press.
  • The coconut cream needs to be warm but not hot when poured, or it’ll melt those beautiful stripes underneath.
03 -
  • Layer the next color only when the previous one has set enough to support it, but isn’t rock solid—timing is everything.
  • For clean, even layers, keep a little jug of hot water to clean your offset spatula or knife between pours.
