1. Preheat oven to 350°, line the bottom of an 8″ cake pan with parchment paper, and spray the pan with non-stick spray.
  2. In a medium bowl, whisk together the flour, baking powder and salt and set aside.
  3. In a large bowl, cream together the butter, sugar and lemon zest until nice and fluffy. Add the eggs and mix until incorporated, then do the same with the egg yolks. Stir in the vanilla extract.
  4. Add half the dry ingredients to the batter and mix until just combined, then the coconut milk, then the other half of the dry ingredients.
  5. Pour the batter into the prepared pan and smooth out the top. Bake for 35-40 minutes, or until a toothpick inserted in the centre of the cake comes out clean.
  6. Let cake cool in the pan for about 15 minutes, then turn it out onto a cooling rack to completely cool down.
  7. Once the cake is cool, top with whipped cream, berries and lemon zest.
