  • 2 tbsp Demerara sugar

Icing -

  • 1/2 cup Icing sugar
  • 1 tsp maple syrup
  • 1 tbsp Water
  • Pinch of salt


  • To make the cake, preheat the oven to 180℃.
  • Add the sugars, maple syrup, oil and eggs in a large bowl and whisk until smooth.
  • In another bowl add the flour, baking powder, baking soda, salt, cinnamon, nutmeg, pecans and stir to combine.
  • Add the dry ingredients into the wet ingredients in 3 parts. Alternating with the mashed sweet potato. Keep whisking until smooth.
  • Line a 9 inch round cake tin with a little baking spray and baking paper. Pour the batter into the tin.
  • To make the crumble: Mix all the ingredients in a small bowl until lumpy but combined. Sprinkle over the cake batter.
  • Bake the cake for 1 hour. Check the cake after 45 mins by poking a knife into the center. If it comes out clean it is baked, if not then bake it some more. The knife should come out clean.
  • Once the cake is baked remove it from the oven and let it cool completely. Ideally on a wire rack.
  • To make the icing: whisk all the ingredients together until smooth. If the icing is too thick add a drop of water to thin it out. If it is too thin add a tablespoon of icing sugar to thicken it up.
  • Drizzle the icing over the cake, slice and serve. Enjoy with tea or coffee.


  • Boil your sweet potatoes with the skin on, once it is totally soft, peel and mash until its a puree. Make sure there are no lumps.
  • I like to sift the dry ingredients a couple of times before incorporating into the batter.
  • Check the write up above for substitute details.
