Note: this cake will sink as it has no flour to hold its rise.
Optional: Serve topped with a delicious Vegan Cream Cheese Frosting: you will need 270g can coconut, chilled overnight + 1/4 cup coconut yoghurt, 1/4 cup coconut oil (melted) and 3 tablespoons pure maple syrup. Use an electric beat to beat the cream on medium until soft peaks form. Add remaining ingredients with a generous pinch of sea salt and mix to combine. Chill for at least 1 hour to firm up. Use immediately.
