Chop the chocolate and - depending on the room temperature - put it in the refrigerator. Mix the butter or margarine with the brown and white sugar until frothy. Stir in the vanilla sugar, egg and a pinch of salt. Slowly knead in the flour, oat flakes and almonds with a little milk so that the dough has a malleable consistency. Finally fold in the chopped chocolate.
Shape the dough into flat rolls and cut into slices about 1cm wide. Roll these slices into balls and place them on a baking sheet with a little pressure. Bake the biscuits at 175 ° for about 10-15 minutes.
Instead of whole milk and white chocolate, other types of chocolate can be used depending on your taste, such as B. Dark chocolate.
