Mix flour, almonds and baking powder. Place the fat, 125 g sugar, 50 g marzipan and 1 egg in a mixing bowl and fold in with the dough hooks of the hand mixer. Finally, work into a smooth dough with cool hands.
Leave to rest in the refrigerator for about 1 hour. Roll out the dough on a floured work surface to a thickness of about 5 mm. Cut out hearts with a heart cutter (approx. 5.5 cm Ø) and place them on two baking trays lined with baking paper.
Bake in the preheated oven (electric oven: 200 °C/ gas: level 3) for 6-8 minutes until golden brown. Let cool on a cake rack. In the meantime, knead the remaining raw marzipan mixture, the remaining egg and sugar into a smooth mixture.
Pour into a piping bag with a perforated spout and spray onto the edges of the heart. Lightly brush a knife with oil and press several notches into the marzipan mixture with the back of the knife. Mix the egg yolk and cream and brush the marzipan rim with it.
Bake in the preheated oven (electric oven: 200 °C/ gas: level 3) for 4-6 minutes until golden brown. Let them cool down. Melt the chocolate coating on a hot water bath and fill the hearts with it in the middle using a teaspoon.
Allow to set slightly in the refrigerator. In the meantime, cut the cherries into quarters, halve the pistachios lengthwise. Cover hearts with it. Let the chocolate coating set completely in the refrigerator.
