Prepare the Banana Chocolate Sponge Cake.

  • Preheat the oven to  350°F (180°C). Grease with butter a 8 inch (20cm) pan and line with parchment paper.
  • In a medium bowl, stir together flour, cocoa powder, baking powder, baking soda and salt.
  • In another bowl mash banana with a fork and set aside.
  • In a large bowl add egg, both sugars, vanilla extract and vegetable oil. Mix until well combined. Add mashed banana and mix to combine.
  • With the mixer on low, incorporate the flour mixture.
  • Pour batter into the prepared pan.
  • Bake for 10-12 minutes, until a toothpick inserted into the cake comes out clean. Let cool completely and transfer to a serving plate.

Prepare the Pecan Banana Caramel Filling.

  • Low the oven temperature to  300°F (150°C).
  • Place the pecans into a parchment paper lined baking sheet and let them toast for 15 minutes. When cool, cut the pecans in smaller pieces.
  • Cut a large banana into thick slices.
  • Place the sugar and water in a medium heavy bottomed saucepan over medium-high heat, and cook without stirring until sugar dissolves and gets a dark caramel color.
  • Add the cream. It will bubble a little bit.
  • Add the banana slices, butter and salt and let cook for about 1 minute stirring constantly with a wooden spoon or spatula.
  • Spread the pecan banana caramel filling over the chocolate banana sponge cake and refrigerate until you prepare the chocolate mousse.

  • Meanwhile dissolve gelatin in cold water and let it swell for about 5 to 10 minutes. Dissolve gelatin over low heat, pour over the melted chocolate and stir to combine. Let the chocolate mixture cool completely at room temperature.
  • Whip the remaining 1 1/2 cup (360g) chilled whipping cream until soft peaks form. Add melted chocolate mixture and mix until well combined.

Assemble the cake.

  • Place a cake ring around the cake and line with an acetate sheet.
  • Pour the mousse on sides and top. Smooth the top using an offset spatula.
