Raindrop cake is actually called “Mizu Shingen Mochi” in Japanese. It is a jelly-like dessert made from water and agar powder and it looks just like a giant raindrop. The dessert originated in Yamanashi prefecture, which has a Japanese sweets shop that first sold this dessert.

Quick Stats:- 

  • Prep Time: 5 minutes 
  • Cooking Time: 10 minutes 
  • Servings: 1 big cake 


  • 3/4 cup water
  • 1/8 tsp + 1/16 tsp agar powder


  • 1/2- 1 tbsp roasted soybean flour
  • 1-2 tbsp black sugar syrup

Method to Prepare:- 

  • In a small saucepan, add agar powder and water and stir with a spatula a few times, until the agar powder dissolves into the water.
  • Turn your stovetop to medium heat and bring the agar water mixture to a boil. 
  • Maintaining a medium heat level, allow the mixture to boil (without a lid) for one minute, then turn off the heat. 
  • Try to be as accurate with the timing as possible. If you don’t heat long enough, your agar won’t be fully dissolved. 
  • If you cook too long, your mixture will condense down too much. Use a spatula to stir the mixture a few times. 
  • Pour mixture into molds. You should have enough to fill exactly two cavities if you are using the silicone molds I used.
  • Place molds into the fridge to set. I recommend letting them sit overnight, or at least 10 hours. 
  • When they are ready, they should easily slide out just by you slightly tilting the molds. 
  • Do not take the cakes out of the fridge until you are ready to serve because they will start to melt after 20-30 minutes. 
  • Add your cakes to a plate. Add some soybean flour to your plate and drizzle black sugar syrup on top of the cake or on the side.

Recipe Notes:- 

  • 1 cake is about 30-50 calories, depending on how much of the toppings you add.
  • Consume within 30 minutes, otherwise, it will melt.
  • The mixture makes more than you need to fill, depending on the mold size. You can put the leftover to set in a small cup.
  • I bought agar agar powder from Japan. If you would like to know more about the difference between coagulants, read here. 
  • The type of agar powder I used and the ingredients of the original raindrop cake “Mizu Shingen Mochi” does start to re-liquefy at room temperature, therefore it needs to be consumed quickly after serving.
