How to make your own edible slime

It was the craze of the summer two years ago, with kids everywhere attempting to make their own slime. And with families now stuck at home in lockdown, the gooey creation is back once again!

Juliet Sear shows us how to make spectacular edible slime that everyone will want to taste!

Marshmallow slime



150g mini marshmallows (I used white but you can use a mixed pack if you wish your slime will just be a light pink instead of white)

80-90g cornflour plus extra for dusting the surface

50g icing sugar

50g veg oil

1 tsp vanilla extract

Cake sprinkles (optional)


  • Melt the marshmallows in a large heatproof bowl in the microwave for 30-50 secs, until melted, stirring after 30 seconds

  • Stir in the oil and vanilla, mix well and then stir in the cornflour and mix again

  • Add icing sugar and stir in and now knead until flexible. If it feels a little sticky, add in the rest of the cornflour.

  • Use extra cornflour for the surface if you need to, having a little veg oil to hand is good to keep your hands sticky free. Knead and play. Add some cake sprinkles for a funfetti effect!



100g Cornflour

2 sachets sugar free jelly (lime or strawberry is nice for a green or red colour)

70g warm water


  • Combine the powders in a bowl with a fork, stir in the water. It might seem a little solid but after a lot of kneading (with your hands) it becomes good stretchy consistency for playing with.

  • There are a range of different fruity jelly flavours to choose from, so can be pink (raspberry) red (strawberry) or green (lime)

Chocolate slime



100g Cornflour

20g cocoa powder

95g coconut milk


  • In a bowl, dry whisk the cocoa into the cornflour

  • Gently warm the coconut milk, then pour over the powder, stir well. Get your hands in and knead it until it comes together and is like stretchy play dough.

  • This one is perfect for making all sorts of shapes, especially the poop emoji!
