Ingredients

For the cake:

  • 3 bananas very ripe
  • ¼ cup sweetened condensed milk
  • ½ cup butter
  • 1 cup granulated sugar
  • teaspoons vanilla extract
  • 2 large eggs
  • ½ teaspoon salt
  • 2 teaspoons baking powder
  • cups all-purpose flour

For the Caramel Filling:

  • ¼ cup butter
  • ½ teaspoon salt
  • cup dark brown sugar
  • ¾ cup sweetened condensed milk

For the frosting:

  • cups heavy cream (also known as double cream) chilled
  • ¾ cup powdered sugar
  • 2 teaspoons vanilla extract
  • 2 tablespoons skimmed milk powder

For the cookie crumbs:

  • ½ cup crushed graham crackers or digestive biscuits

For topping:

  • dark chocolate shaved

Instructions

For the cake:

  • preheat the oven to 350F.  Grease two 8 inch round cake pans
  • Place the condensed milk, bananas and vanilla extract in a mid-sized microwave-safe bowl.  Heat in the microwave on high for 45 seconds to 1 minute or until warmed through and fluid.
  • Mash the warm bananas well into the condensed milk. Mix to combine and set aside.
  • In a separate large bowl, beat the butter and sugar until the mixture is light and fluffy. Beat in the banana mixture. Beat in both eggs until combined.
  • Mix in the salt and baking powder. Mix in the flour until combined.
  • Add the batter evenly between the cake pans.
  • Bake for 25-30 minutes or until a cake tester comes out clean. Leave to cool 10 minutes before turning out onto a wire rack to cool completely.

For the caramel filling:

  • Melt the butter, salt and dark brown sugar into a non-stick pan over low heat, stirring continuously until the sugar has dissolved.
  • Add the condensed milk and bring to a rapid boil for about a minute, stirring the whole until it forms a thick golden caramel.  Set aside to cool completely at room temperature.

For the Frosting:

  • Add powdered sugar, skimmed milk powder, and vanilla to the cream.
  • Using a food processor or mixer, whip the cream until it thickens (this doesn't take long at all so check often). When you run a spoon through it, and it holds its shape without falling back into the gap, it's ready to use.

To Assemble:

  • Place the first layer on a cake plate and cut any mound off the top to make it even.
  • Add the caramel filling to the bottom layer.
  • Top with the second layer and cover in the whipped cream frosting.

Crumb Coating:

  • Gently pat the crumbs into the frosting, working your way around the cake. Don’t press too hard—use just enough pressure to ensure the crumbs stick to the frosting.

To Top:

  • Using a fine cheese grater, grate the chocolate onto the top of the cake.
  • Refrigerate cake until 30 minutes before ready to serve. Then refrigerate to store leftovers. This cake is best for 2-3 days.

Notes

  • Don't worry about lumps in the batter.  The mashed banana will not completely break down and will leave lumps.  As long as the flour is mixed in, lumps are fine!
  • Don't over mix the batter. As shown in the video, I add the flour in stages and finish by hand so as not to over mix. Over mixing will create a heavy, dense cake.
  • Be careful not to overcook the filling.  Follow the instructions and don't cook too long or you may end up with hard toffee.
  • Use chilled whipping cream. Whipping chilled cream is faster and the result is lighter. If using a mixer, chill the bowl and whisk or beaters too before whipping the cream.
  • Avoid over whipping the cream. Cream whipped to stiff peaks can quickly separate into butter if over whipped.
  • Storing the cake: Refrigerate cake until 30 minutes before ready to serve. Then refrigerate to store leftovers. The cake is best for 2-3 days.
Coating the side of the cake: 
  • Gently pat the coating into the frosting:  Work your way around the cake, patting the coating into the frosting. Be careful not to press too hard; only use enough pressure to ensure the coating sticks to the frosting.
