Instructions

  1. Make the cake: In a bowl, combine all the wet ingredients for the cake. Mix really well until the sugar is well dissolved.
  2. Then add the flour, flax meal, cornstarch, baking powder, and salt on top of the wet ingredients.
  3. Use a whisk or spatula to mix in the dry ingredients above the wet ingredients so the baking powder, salt mixed into the flour, then slowly mix it into the wet ingredients.
  4. You can also mix the dry ingredients in a separate bowl and then add in the wet ingredients. Add half first and mix in lightly then add in the rest of the half and mix in to make a batter. If the batter is too thick, add in 1-2 teaspoons more non-dairy milk and mix in.
  5. Line an 8 inch or a 9 inch round cake pan with parchment and grease the sides then pour the batter into the cake pan.
  6. Even it out on top then bake at 350 degrees Fahrenheit (180 degrees Celsius) for 25 minutes. Check at the 25 minute mark. If the cake is not done yet, bake for another 5 minutes.
  7. Remove the cake from the oven and let it sit for 10 minutes to cool and then remove from the pan. To cool the cake completely, cover it with a kitchen towel and put it in the fridge.
  8. Make the custard: Blend the cashews, water, vanilla, almond extracts, turmeric, sugar, and cornstarch, and flour. Blend for 1 minute then let this mixture sit for 5 minutes. Then blend again. Repeat for another 2 times until the cashews are well blended in.
  9. (You can also soak the cashews in hot water for 15 minutes and Drain and then use. Usually blending and waiting works out really well even if they're not soaked.)
  10. Transfer this mixture to a saucepan over medium heat. After a minute or so, start whisking a bit so that the bottom doesn't scorch.
  11. After another few minutes, the custard will start boiling. As it boils, it will thicken unevenly and look lumpy. As you keep whisking, it will become smooth. Let the custard boil consistently for a minute and thicken and then take off heat.
  12. Let the custard cool. Put it in the fridge for about half an hour.
  13. Just before you are ready to assemble, make your chocolate frosting: Add the coconut cream and maple syrup to a small skillet over medium heat.
  14. Once the coconut cream and maple mixture starts boiling, whisk really well to mix in. Then take off heat and Add the chocolate. whisk until the chocolate is well-melted.
  15. Remove the cake from the fridge. Using a really sharp knife, slice it into 2 layers.
  16. Remove the custard from the fridge as well. Add a thick layer of custard on one of the slices, even it out with a spatula. Then put the other slice on top.
  17. Keep the custard layer at 3-4 mm thick , if it’s too thick it will ooze out too much when you slice The assembled cake. Use any remaining custard to serve separately.
  18. If the chocolate is too thin, freeze it for 15 minutes so that the consistency thickens a little bit and is easier to spread. Or refrigerate it for half an hour so that this is more like a frosting and then spread it.
  19. Pour the chocolate ganache all over the cake and spread it out with a spatula. Also spread it on the sides.
  20. Once it is spread evenly, let the cake chill in the fridge for half an hour so that the chocolate sets. Slice it and serve it with an extra helping of the custard. Store the cake refrigerated for upto 4 days .

Notes

  •  Gluten-free: use 1 cup almond flour, 1/2 cup oat flour, and 1/3 cup potato starch. Mix really well. Add 1 1/2 cups of this flour to the wet mix along with the flax seed meal, baking powder, and salt. omit the cornstarch. mix in. If the batter is too liquidy, add in the rest of the flour, a  tablespoon at a time. For the wet ingredients, use 3/4 cup of non-dairy milk and 1/4 cup of club soda instead of the 1 cup and 2 tablespoons of non-dairy milk.
  • To make the custard Nutfree, you can use more cornstarch. I don’t particularly like that texture and that custard also won’t hold up much for a thick enough layer. But you can serve with extra custard on the side
