  • 4 cups rice bubbles
  • 75 grams butter, cubed
  • 180 grams marshmallows
  • sprinkles (to decorate)


  • Grease a slice tin (approx 28 x 18cm) and line with baking paper, leaving paper overhanging at sides to assist with removal of slice later.
  • Measure rice bubbles into a large mixing bowl.
  • Melt butter and marshmallows over low heat until mixture is melted and smooth (with no marshmallow lumps - keep going if it still looks like the mixture pictured!).
    rice bubble slice method, melting mixture
  • Pour butter and marshmallow mixture into rice bubbles and stir to combine.
  • Pour mixture into slice tin. The mixture is too sticky to press into the tin with your hands so you'll need a piece of baking paper placed over the mixture first. Then press into tin using the back of a metal spoon. Remove top piece of paper, add some sprinkles to the top and place into fridge to set.
  • Allow to set for at least a couple of hours before removing the slice from the tin and cutting into squares.
