Make the white icing by mixing a few drops of tap water into the icing sugar. Mix together until you have a thick paste. You can get your kids to guess how many drops of water it will take to make this!
Take a vanilla wafer biscuit and add a small blob of the icing in the middle of the biscuit. Leave it to set for a few minutes if you like.
Add a small blob of strawberry jam into the middle of the white icing. Leave to dry!
