4. 4
   Add the pureed banana and milk and mix well.
5. 5
   In another bowl, sift all of the dry ingredients together and combine with a whisk and then mix with the wet mixture, taking care not to over-mix.

   Pour the mixture into the dish and fan-bake at 200 celsius for 25 minutes.
7. 7
   Meanwhile make the sauce:.
8. 8
   Put all of the ingredients except for the rum essence into a pot and gently heat until combined and then leave to boil for 5-10 minutes (until it's very syrupy).
9. 9
   Note: When you take it off the element and begin to cool it it will thicken a little more, but it's supposed to be really runny.
