Rainbow Gelatin Cake by tsunekawa

If you’re enjoying cooking and baking at home right now but you’re fresh out of new ideas, here’s an eye-catching dessert you could try that will impress everyone in your household. Japanese pop-up restaurant owner tsunekawa recently shared his recipe for a mesmerizing, rainbow milk gelatin cake that is surprisingly easy to make.

Don’t feel intimidated by its dazzling, prism-like beauty—even the most novice cooks and bakers can throw together this cake in just 30 minutes, and you’ll only need a handful of ingredients. It not only looks great—the finished flavor is sweet and creamy, with a fun, jiggly texture. Sold? Here’s how to make it at home:


  • Kanten (aka agar powder, available at most Asian markets)
  • Water
  • Granulated sugar
  • Milk
  • Shaved ice syrup (or fruit juice)



Step 1. Combine 4 grams (0.14 ounces) of agar powder, 150 ml (5.07 ounces) of water, and 60 grams (2.12 ounces) of granulated sugar in a pot. Heat on the stove until the mixture comes to a boil, then turn off the heat.

Step 2. Stir 300 ml (10.14 ounces) of milk into the mixture. Place the mixture in the refrigerator to chill and wait until it solidifies into gelatin.

Step 3. In a separate pot, repeat step 1.

Step 4. Stir an additional 300 ml (10.14 ounces) of water into the second pot, add 20 ml (0.68 ounces) of shaved ice syrup (the more brightly colored the better). Once again, put the mixture in the fridge to cool and solidify.

Step 5. (optional). Repeat steps 3 and 4 for any additional colors you want to use.

Step 6. Allow everything to chill for around 30 minutes. Take the colorful mixtures out of the fridge.

Step 7. Cut the colorful gelatin into small cubes and arrange them on top of the white milk gelatin, which will serve as the base.

Step 8. Serve and enjoy!

It's hard to deny its resemblance to an iridescent opal stone.

But the recipe allows you to use any combination of colors you choose, and others are now sharing their own versions to great effect.
