Sweet Potato Chocolate Cake

This recipe was brought to you by Dr. Renae Thomas.

Dr Thomas could sit just as comfortably alongside the athletes in this book. As a
former Australian champion in gymnastics, marathon runner and fitness competitor,
she’s more qualified than most to talk about the intersection between diet and athletic
performance, as well as overall health.


  • 450 g (1 lb/11/2 cups) boiled sweet potato chunks
  • 180 g (61/2 oz/1 cup) medjool dates, pitted (approximately 20 large)
  • 1 tablespoon reduced balsamic vinegar
  • 1 teaspoon vanilla-bean powder
  • 250 ml (81/2 fl oz/1 cup) non-dairy milk of your choice
  • 60–90 g (2–3 oz/½–3/4 cup) cacao powder
  • 240 g (81/2 oz/11/2 cups) sweet potato flour (see Note)
  • 1 teaspoon baking powder
  • 70 g (21/2 oz/1/2 cup) shredded zucchini (courgette)
  • 30 g (1 oz/1/4 cup) walnuts (optional; see Note)
  • fresh berries, to serve (optional)


  • 165 g (6 oz/3/4 cup) peeled, boiled and
  • mashed sweet potato
  • 60 g (2 oz/1/2 cup) cacao powder
  • 80–180 g (23/4–61/2 oz/½–1 cup) medjool dates, pitted (depending on the desired sweetness)
  • 125 g (41/2 oz/1/2 cup) almond, hazelnut or cashew-nut butter (or 1 avocado for a nutfree version)
  • 125 ml (4 fl oz/1/2 cup) non-dairy milk of your choice


  • Step 1

    Preheat the oven to 180°C (350°F). Line a 20 cm (8 in) round cake tin with baking paper.

  • Step 2

    Combine the sweet potato chunks, dates, balsamic, vanilla powder and milk in a highspeed blender and blitz until smooth.

  • Step 3

    Sift the cacao powder, sweet potato flour and baking powder into a large mixing bowl. Stir in the zucchini and walnuts, if using. Add the sweet potato mixture and stir until just combined.

  • Step 4

    Pour the mixture into the prepared tin and bake for approximately 40 minutes to 1 hour, or until a skewer inserted in the middle of the cake comes out clean. Transfer to a wire rack to cool completely.

  • Step 5

    To make the icing, blend all the ingredients together until smooth in a food processor or highspeed blender. Spread over the cake and garnish with fresh berries, if desired.

  • Step 6


  • Step 7

    If you cannot find sweet potato flour, you can substitute it with other grain-free options, such as banana flour or chestnut flour. Alternatively, you can use 185 g (61/2 oz/11/2 cups) steel-cut oats blitzed into oat flour, though the cake will no longer be grain-free.

  • Step 8

    Adding walnuts to this cake will increase the fat content.

  • Step 9

    This cake is particularly good with a scoop of banana ‘nicecream’; blended frozen banana and vanilla-bean powder.
