This is what my mom makes when there is left over ripe banana at home. It's a yummy dessert.
Mash Banana in a bowl. Add Rice powder, flour, jaggery and milk. This should make a thick batter. The batter consistency must be like that of cake batter.
Fry Coconut Pieces in ghee till its golden brown. Add it to the mixture. Fry the raisins and cashew nut and add it to the mixture and mix well.
Heat appam pan in a vessel containing oil. Oil should fill half of the appam pan.
Once the oil is hot, add small portions of batter into the appam pan. Turn over and cook till its golden brown.
