Mix the flour with the baking powder, put the butter on top in flakes, add the sugar, almonds and eggs and quickly knead into a smooth dough. Wrap in cling film and place in the refrigerator for at least an hour.
Heat the oven to 175 degrees top / bottom heat.
Halve the dough and put one half back in the refrigerator. On a floured work surface, roll out the dough to a thickness of approx. 3 - 4 mm and cut out cookies with a round or wavy edge with a cookie cutter dipped in flour. Do the same with the second half of the dough, making a hole in the middle of the cookies.
Bake the cut out cookies one after the other on a baking sheet lined with baking paper for about 12 minutes.
After baking, remove the cookies from the tray and let them cool down. Warning: they are easily breakable when hot.
Brush the unperforated cookies with jam or jelly, place a perforated cookie on top and dust with powdered sugar.
