Banana and Whipped Cream dome cake recipe

Author: Petro


  • For the cake
  • 3 eggs
  • 5 oz = 150 g cake flour
  • 4 oz = 125 g caster sugar
  • 2 teaspoons baking powder
  • 1 tablespoon cocoa powder
  • 6 medium large bananas
  • 2 sachets Dr Oetker vanilla sugar
  • For the whipped cream:
  • 2 tablespoons sugar
  • 1 cup heavy whipping cream
  • 1 cup chocolate chips


  • For the cake:
  • Heat oven to 375 F = 190 C
  • Line a 9" = 24 cm cake pan with a removable bottom with baking paper.
  • Sift flour.
  • In a large bowl, whisk the flour with baking powder and cocoa powder.
  • Separate the egg whites and yolks from 3 eggs.
  • Beat egg whites with a whisk until you get a stiff foam.
  • Incorporate the sugar and vanilla sugar gradually and continue whisking until you get a dense and glossy meringue like mixture.
  • Incorporate the yolks, one by one, mixing gently with a spatula.
  • Incorporate all flour cocoa mixture, gradually. You should get an airy dough.
  • Pour it into the cake pan, level with a knife and bake for 20-25 minutes or until a toothpick comes out clean.
  • Remove from the oven and allow to completely cook into the cake pan.
  • For whipped cream:
  • I prefer the hand method but it takes a bit of an arm work so if you're not a fan, use a hand mixer (not a stand mixer, it doesn't whip through the bottom).
  • Place the sugar into the mixing bowl and add the whipping cream.
  • Whisk until the cream reaches stiff peaks.
  • Gently stir in the chocolate chips
  • Store any unused portion in an airtight container for up to 10 hours. When ready to use, rewhisk for a few seconds.
  • To assembly the cake:
  • When the cake has cooled completely, cut the top so that the base has 2" = 5 cm.
  • Using a spoon, make a hollow inside, leaving a 1" = 2.5 cm rim around the edges.
  • Set the crumbs aside.
  • Crumble into fine crumbs (I used my food processor).
  • Peel bananas, cut in slices and place them in the hollow formed inside the cake.
  • Place the whipped cream over bananas in a dome shape.
  • Sprinkle the fine crumbs all over.
  • Transfer to the fridge and chill for at least 2 hours then cut as you would a regular cake.
