Whisk the fat, sugar and 1 pinch of salt with the whisk of the hand mixer until thick and creamy. Stir in the eggs one after the other. Mix flour and baking powder and stir in alternately with the pineapple juice. Pour the dough evenly into 8 greased and flour-blended muffin tins. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 25-30 minutes. Remove the muffins from the cake tins and let them cool on a cake rack.
In the meantime, peel the baby pineapples. Cut into wafer-thin slices and turn in flour. Heat the fat in a small pan. Fry the pineapple slices in it, take them out and let them drain. Mix coconut liqueur and icing sugar to a smooth glaze and cover muffins with it. Decorate with cocktail cherries, pineapple slices and grated coconut
