Cream fat and sugar. Add 2 eggs one after the other and stir the mixture until creamy. Mix flour, baking powder and cinnamon, sieve onto the fat egg mass, add almond liqueur and stir in.
Spread the dough into a greased springform pan (24 cm Ø). Clean, wash, cut and stone the plums. Place them on the dough with the inside facing upwards in scales. Cream remaining eggs, honey and lemon peel.

Let the cake cool down. Serve dusted with the icing sugar. Makes about 12 pieces.
