Before you start, ensure that you can devote 20 minutes of your time to this recipe, it needs your full attention as the gelatin sets very quickly.
Prepare a 9in square cake pan by lining with parchment paper. Set aside.
Place half the water and all the sweetener into a small saucepan over high heat. Bring to the boil.
In your stand mixer, add the remaining water and sprinkle over the gelatin. Immediately add the boiled water mixture. Give it a quick mix with a spoon to help the gelatin dissolve.
Whisk on high speed for 10-15 minutes, until the mixture is a glossy white colour and has formed soft peaks.
Gently and quickly scoop the mixture into your prepared pan and smooth the top.
Leave to set for 4 hours at room temperature.
Once set, remove the parchment from the pan and gently pull the sides flat.
Spray your knife with coconut oil before gently cutting the marshmallow into 6 thick slices using a slight drag (to break through the top) then press motion (to cut all the way through). You will need to keep spraying coconut oil onto the knife before making each cut to prevent the marshmallow from sticking.
Cut each strip into squares.
