Homemade Ube Marshmallows (No corn syrup)

Soft, fluffy marshmallows with a hint of ube flavor! This recipe makes about 10-20 large marshmallows.
Prep Time 20 minutes
Resting Time 8 hours
Cost $3.74


  • saucepan
  • candy thermometer
  • hand or stand mixer
  • 8-inch square pan lined with parchment paper


  • 2 packets gelatin (Knox brand) (14g or ~4 tsp, $1.45)
  • ½ c cold water (118g, $0.50)
  • 1 ½ c sugar (300g, $0.58)
  • ½ c water (118g, $0.50)
  • 1 tsp ube extract ($0.14)
  • purple food coloring, optional, see notes
  • 1 c powdered sugar, for dusting (130g, $0.57)


  • Prepare an 8-inch square baking pan by lining it with parchment paper. Using a sieve, generously dust with powdered sugar.
  • In a large metal/ceramic mixing bowl (no plastic! we will be pouring hot liquid into it later) or bowl of stand mixer, pour the ½ c cold water, then sprinkle on two envelopes of gelatin on top. Set aside to let the gelatin soak up the liquid.
  • In saucepan, add ½ c water and all of the sugar. Turn heat to medium and let it cook for a few minutes until the sugar fully dissolves.
  • When the mixture starts boiling, check temperature using candy thermometer. Once it reaches about 240°F/115°C, remove sugar water mixture from heat.
  • Turn on hand/stand mixer to medium speed and whip the thickened gelatin while slowly adding all of the hot sugar water mixture.
  • Once all of the sugar water is added, add the ube extract and keep mixing on medium speed. If you want a deeper purple color, add your purple food coloring now.
  • Whip for about 10-15 minutes, or until the mixture is thick, glossy, doubled in size, and reaches soft peaks. If you overwhip, the mixture will be dull, come apart easily, and hard to spread.
  • Add all of the marshmallow mixture into your prepared square pan. Level and smooth the top. Dust with more powdered sugar and leave uncovered overnight (or ~8 hr) to allow the marshmallow block to fully set.
  • Remove marshmallow block from pan and cut into sizes. Dip cut sides into powdered sugar to prevent them from sticking.


Since ube extract typically has red + blue dyes in it, I didn't add any extra purple food coloring. Feel free to add some if you want a deeper purple color! 
Store marshmallows in an airtight container, separated by layers of wax or parchment paper. Keep in cool, dry place for up to one month.
