For the caramel

  • 450g sugar
  • 450g cream
  • 150g walnuts chopped
  • 5g salt

For the cake

  • 350g ripe bananas pureed (around 4)

  • 2 eggs
  • 320g plain flour
  • 2 g cinnamon powder
  • 5g baking powder
  • 5g bi carb soda
  • 3g salt
  • 1 lemon juiced


  1. Place the EasySear pan from the slow cooker onto a low heat, add the sugar and cook for 15 minutes or until the sugar turns to caramel, stir gently several times to ensure the sugar melts evenly.
  2. In another pot heat the cream to just below boiling then slowly pour the heated cream into the caramel sugar pot. Heat the caramel mixture up to just below boiling then add the chopped walnuts and the salt.
  3. For the cake,mix the purred banana and sugar together with the oil and the eggs.
  4. Sift in the flour, bi carb, baking powder and salt. Then lightly fold through the mix. Add the lemon juice and lightly mix together.
  5. Pour the cake batter on top of your caramel walnut mix in the EasySear pan
  6. Using a tea towel carefully place the EasySear pan back into the slow cooker base and place on the high setting  and cook for 45 minutes or until a skewer comes out clean when inserted into the centre .
  7. After 10 min remove the cake from the EasySear pan by upturning onto a large tray, take care when doing this as the caramel at the base will be very hot. Serve warm or cold.
