Cake Ingredients

  • 1/2 cup plant milk
  • 1/2 tsp apple cider vinegar
  • 2/3 cup whole wheat flour
  • 2/3 cup spelt four
  • 2/3 cup oat flour
  • 1/2 tsp baking soda
  • 1 tsp baking powder
  • 1 tsp vanilla extract
  • 3/4 cup date paste or 6 Tbsp pure maple syrup
  • 1/2 cup applesauce
  • 2 Tbsp poppy seeds
  • 1 Orange zested
  • 2 Lemons zested

Cream Cheese Icing

  • 1 1/2 cups cooked purple sweet potatoes without the skin – about 1 1/2 medium sized sweet potatoes
  • 2-4 pitted dates soaked in boiled water for 10 minutes
  • 1/2 cup raw cashews soaked in boiled water for 20 minutes
  • 1 tsp vanilla extract
  • 1/2 cup plant milk
  • 1 Orange zested, to serve

Instructions
 

To make the cake...

  • In a small bowl, make the buttermilk by combining the apple cider vinegar and milk. Set aside for approximately 5 minutes.
  • Preheat the oven to 175°C (350°F). Line a 9-inch round cake tin with baking paper and set aside.
  • Add all dry ingredients to a large bowl, and mix.
  • Add the wet ingredients, including the buttermilk, to the dry ingredients and stir until combined, being careful to not overmix which will make the cake dense. You want the batter just barely mixed.
  • Add the poppy seeds and citrus zests and stir gently until just combined.
  • Transfer batter to the prepared cake tin, and bake for 20-30 minutes (or until a toothpick comes out clean from the centre).
  • Allow the cake to cool completely in the tin before removing and icing.

To make the icing...

  • Preheat oven to 220°C (425°F) and line an oven tray with baking paper.
  • Using a fork, poke a few holes in the sweet potatoes to create steam vents (otherwise they may split or even burst), then bake for 45-50 minutes.
  • Bake
  • When they are fork tender, remove from the oven and allow to cool.
  • When they're completely cooled, slice the sweet potatoes in half and scoop out the flesh with a spoon. Place in a food processor or high-powered blender.
  • Drain the soaked cashews and dates and add to the sweet potatoes.
  • Add the vanilla and milk, and process until smooth.
  • Refrigerate for 20 minutes before icing the cake.
  • Add the orange zest prior to serving.
