Mix the butter and sugar for a good 5 minutes until frothy. Fold in the eggs one by one and stir for one minute at a time. Sift the flour into a second bowl. Add the coconut flakes and baking powder. Add these dry ingredients to the liquid mixture. Also add the coconut milk and stir the dough well again.
Put the dough in a greased springform pan lined with baking paper and bake at 170 degrees for about 45 - 50 minutes. The baking time is different for each stove, so make a stick test in any case. The cake may need to be covered halfway through the baking time when baking.
When the cake is ready, mix the 30 g sugar with the 100 ml coconut milk and pour over the hot cake. Now he should go through a couple of hours.
