Drain the cherries well in a sieve. Pour 1 cup of crème fraîche into a bowl, set aside. Wash and dry the cup. Beat butter, salt and 1 cup of sugar until creamy with the whisk of the hand mixer.
Stir in 3 eggs one after the other. Sift flour and baking powder over the butter mixture and fold in with a whisk. Pour the dough into a greased springform pan (26 cm Ø), dust with flour. Turn cherries into 1/2 cup of grated coconut and spread evenly on the dough.
