Preheat the oven to 180°C
Melt the butter in a saucepan.
In a middle-sized bowl whisk together the eggs and the coconut milk.
Add the flour, the baking soda, the sugar and the melted butter and mix until you get an even dough.
Finally add the berries and mix again.
Put the dough into a cake pan and let it bake for 50 min.
Let the cake cool before you take it out of the pan.
Enjoy!
