  2. To prepare the base, cream the butter, sugar and essence for 4 minutes until pale and creamy
  3. Add egg and mix well
  4. Add dry ingredients (it says to sift but I never do...)
  5. Pour into a slice tin or square 25cm tin (or as original recipe states 2 sandwich tins)
  6. Bake for 13 minutes until light golden brown on top
  7. Set aside to cool
  8. To Prepare the marshmallow - boil water, gelatine and jelly crystals in a large pot on the stove top - for 8 minutes
  9. Add sugar and stir well to dissolve it all and remove from the heat and allow to cool completely.
  10. Beat with electric mixers until thick but not too stiff and unable to be spread - this can take up to 5 minutes

  12. Pour marshmallow over the base and pop in the fridge to set - for approx. 2 hours
  13. Slice and store in the fridge in an airtight container.
