Preheat the oven to 180°C or 350°F. Line a baking tray with parchment paper. Set aside.
Roll out the dough on a floured surface until it's 2 cm thick (do not go thinner than 1 cm). With a bone shaped cutter, cut the dough and place them on the sheet of parchment paper, leaving some space between one another.
Place a generous layer of the almond filling on the dough. Cover the almond filling with another piece of bone shaped dough and seal well the sides.
Bake the biscuits for about 30 minutes or until lightly golden.
When the biscuits are cooked, first let them rest on the baking tray before moving them to a cooling rack as this may cause them to break. After some minutes, transfer to a cooling rack to let them completely cool. It is best to let them rest for a while.
