Knead flour, baking powder, fat, eggs and cream with the dough hooks of the hand mixer to a smooth dough, cover and refrigerate for about 30 minutes
Roll out the dough on a floured work surface to form a square (40 x 40 cm). Cut out about 50 squares (4x4 cm). Put a blob of jam on each half of the squares, cover with a second one and press slightly on the edges
Place the cookies on baking trays lined with baking paper and bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 15-20 minutes. Allow to cool and dust with powdered sweetness
