I was given Sue Shepherd’s recipe book, ‘The Gluten-free Kitchen’ for Christmas and have already made two cakes out of it. The book has wonderful photos and easy recipes that don’t involve too many ingredients.

For my Mum’s birthday I decided to make the Banana Hazelnut Cake. I was intrigued to see that the recipe included 150g mashed potato (instead of flour), however the forward of the recipe actually notes not to be alarmed about this unexpected ingredient.

The cake turned out amazing and everyone highly enjoyed it – some even going back for seconds – and you wouldn’t even realise that it had potato in it!

Banana Hazelnut Cake


  • 4 eggs, separated
  • 2 teaspoons vanilla essence
  • 1 teaspoon gluten-free baking powder
  • 1/2 teaspoon bicarbonate of soda
  • 180g caster sugar
  • 40g butter, at room temperature
  • 1 teaspoon ground cinnamon
  • 150g cooled smoothly mashed potato
  • 2 medium ripe bananas mashed
  • 1 1/2 cups ground hazelnuts
  • 1/2 cup chopped walnuts
  • pure icing sugar, for dusting


  1. Preheat the oven to 180 degrees Celsius. Grease and line a 24cm springform cake tin.
  2. Place the egg whites, vanilla baking powder and bicarbonate of soda in a large bowl and beat with electric beaters until firm peaks form.
  3. Beat the egg yolks, sugar, butter and cinnamon until thick, pale and creamy. In a separate bowl, combine the mashed potato, banana, hazelnut meal and walnuts.
  4. Fold alternate batches of egg white and mashed potato mix into the egg yolk mixture.
  5. Spoon the cake batter into the tin and bake for 20 minutes, then cover with foil and cook for a further 10-15 minutes or until a skewer inserted into the centre comes out clean. Serve dusted with icing sugar.
