- Prepare the dough
In a mixing bowl, mix the butter, salt, and icing sugar. Add the almond flour. Mix in the egg, then the flour and mix well. Roll out the dough between two sheets of parchment paper to a thickness of 2 mm. Refrigerate for 1 hour.
- Cut out the biscuits
Cut out oval shapes using a fluted cookie cutter and place them on a baking sheet lined with parchment paper. On half of them, cut out two round discs 2 cm in diameter.
- Baking
Bake the shortbread biscuits at 160°C for about 15 minutes. Allow to cool, then spread raspberry jam over the solid oval shapes. Place the cut-out oval shortbread biscuits on top and dust the whole thing with icing sugar.
