These sweet, soft and fluffy homemade marshmallows are utterly delicious. Perfect for a delightful treat or topping a steaming mug of rich hot chocolate.

Ingredients

Scale

For the raspberry purée:

  • 150g raspberries
  • 1 tbsp caster sugar
  • Splash of water

 

To prep the containers:

  • About 2 tbsp vegetable oil
  • 50g cornflour
  • 1 tbsp cocoa powder
  • 50g icing sugar

 

For the marshmallows:

  • 4 tsp powdered gelatine (12g), plus 2 tbsp cold water
  • 140g liquid glucose
  • 230g caster sugar
  • 150ml water
  • 2 tbsp cocoa powder

Instructions

  1. Begin by making the raspberry purée: tip the raspberries into a small saucepan. Add the sugar and a splash of water. Place over a low-medium heat and bring to a simmer. Continue to cook, stirring occasionally until thickened.
  2. Strain the mixture through a sieve into a clean bowl (or tupperware) to remove the seeds. Leave to cool completely before chilling in the fridge to firm up.
  3. Next, prep the containers: you will need 3 tupperwares roughly about 8cm x 10cm. Brush each container with vegetable oil and set aside. You can adjust the size of the containers depending on how tall you want your marshmallows. 
  4. In a small bowl, mix together 1 tbsp cornflour with the cocoa powder until combined. In a separate bowl, mix together the remaining cornflour with the icing sugar. I like to use a sieve for this bit just to make sure they are completely lump free.
  5. Take one of the oiled containers and tip in the cocoa-cornflour mix, turning to coat the base and all the sides. Tap out any excess onto a non-stick baking tray and reserve for later. Repeat with the other two containers using the icing sugar-cornflour mix. Set aside.
  6. For the marshmallows: place the gelatine into a large heatproof bowl (ideally the bowl of a stand mixer if you have one). Add the 2 tbsp cold water and mix well. Set aside. 
  7. Next, add the glucose syrup and caster sugar to a large saucepan. Pour in 150ml water and place over a medium heat. Stir gently until the sugar has dissolved in the water. Once the mix begins to simmer, stop stirring. Continue to heat over a medium-high heat, gently swirling the pan, until the sugar syrup reaches 115C (use a jam thermometer to check). At this stage the liquid should be clear and bubbling. Handle the pan carefully as it will be extremely hot. 
  8. Remove the pan from the heat and very carefully drizzle the sugar syrup into the gelatine whilst whisking with an electric whisk. You will find this easiest if you use a stand mixer fitted with the whisk attachment.
  9. Once all has been added, whisk on medium-high speed for a further 12-14 minutes - or until you have a thick, white meringue-like texture. 
  10. Divide the mixture equally into 3 bowls. Mix the raspberry purée though one. Sieve the cocoa powder into another. Leave the third bowl plain. 
  11. Spoon the mixtures into their respective flavoured containers and smooth over the top using a spatula or palette knife. Leave to set for at least 2 hours.
  12. Set out your cornflour-dusted baking trays (one with the cocoa-cornflour, the other with the icing sugar-cornflour). Tip the marshmallows onto the respective trays. Dust a large sharp knife with icing-sugar cornflour then cut the marshmallow into equal-sized cubes. Toss to coat each one in the icing-sugar cornflour. Enjoy!

Notes

  • Fruit: you can ring the changes and swap the raspberries for all sorts of berries. Strawberries, blackberries, blueberries and cherries all make delicious marshmallows. If you don’t want to make your own purée, you can use a shop bought one. Strawberry Red and Funkin have some great flavours. 
  • Size: you can cut the marshmallows into whatever size you like. Sometimes I make jumbo marshmallows, other times I make mini marshmallows. You can also use different sized tupperwares to alter the depth. 
  • Make ahead: these homemade marshmallows keep well in an airtight container in a cool place for up to 3 weeks.
  • Serving suggestions: homemade marshmallows are delicious as a sweet treat or dinner party petit four. I also love adding them to a warming mug of rich hot chocolate or making gooey s’mores. Alternatively, pop in pretty bags or boxes and give as a homemade gift.
