For the almond hearts, first knead all the ingredients for the dough into a smooth shortcrust pastry using a mixer and leave to rest in a cool place for half an hour.
Preheat the oven to 180 °C. Line a baking tray with baking paper.
Roll out dough to about 2 mm thick, cut out hearts and place on the tray. Bake for about 10 minutes. Remove and let cool.
Heat the jam and stir until smooth. Spread thinly on the cookies.
Roll out the rolled fondant thinly on some powdered sugar and emboss the pattern on it with the help of an embossing mat. Cut out hearts and place them on the cookies. If you like, you can decorate the almond hearts with icing, sugar pearls or fondant flowers.
