Meanwhile make the batter. Mix almond flour with vanilla, sugar, baking powder and salt. Stir in the egg, coconut oil and coconut milk.
Place the blackberries among the apples in the skillet. Pour the batter on top if the fruit until it covers the surface. It is okay if there is small cracks where the fruit can release some moist.
Bake in the oven for 15-20 min. depending on your oven. The cake should be golden brown on the entire surface and the batter just set.
Serve the cake while it is still a little warm with a dollop of yoghurt, whipped cream or splash of coconut milk – and maybe a few fresh black berries on top.. Enjoy.
Notes
The cake is gluten free, grain free and dairy free. For a vegan option substitute egg with chia gel. Add 1 tbsp chia seeds + 2 tbsp water/apple juice in a glass, stir and set a side for 10 min.
