  • 200 g castor sugar
  • 1 tbsp gelatin unflavored
  • ½ cup hot water
  • ¼ vanilla essence
  • Coloring optional


  • 50 g icing sugar
  • 15 g corn flour


  • Prepare a 6 inches square tin. Grease the tin, line with parchment paper and grease again. Dust with a little icing sugar and set a side.
  • Mix gelatin with half of the hot water and leave aside for the gelatin to bloom.
  • In another saucepan, mix sugar with the remaining half of the water (¼ cup) and cook over low heat until the sugar is dissolved.
  • Continue to cook until the syrup reaches the soft ball stage* or until it reaches between 235 to 240°Fahrenheit or between 112 to 116°Celsius.
  • Pour it into the gelatin mix and stir until gelatin is all dissolved. Let it cool down slightly for about 2 minutes.
  • Whisk the solution on low speed for 3 minutes before increasing the speed to high for another 10 minutes. The mixture should be white and glossy but not too stiff. Add vanilla essence and continue to whisk for another minute. If you wish to color your marshmallows, add the coloring at this stage.
  • Pour the marshmallow mix into the prepared tin and level the top with a spatula.
  • Leave the marshmallow to set at room temperature for at least 8 hours or overnight.
  • Carefully peel off the parchment lining and dust the uncut marshmallow block with the icing sugar – cornflour mix (can use the one mixed for tossing). Grease your knife and cut the marshmallow block into smaller pieces as you wish.
  • This homemade recipe makes a 6 inches square marshmallow block with a height of about 1.3 inches.


* Soft ball stage is when the sugar syrup has thickened quite considerably. To test for the soft ball stage, fill a small saucer with cold water and pour a small amount of the sugar syrup into the water. Push the syrup with your finger. If it forms into a soft ball when pushed, it has reached the soft ball stage.
