Knead the flour, sugar, vanilla sugar, salt, baking powder, soy flour and margarine into a smooth dough. Possibly add an additional tablespoon of margarine, depending on how strong the wholemeal flour is. Now chill the dough for 30 minutes.
Melt the chocolate in a double boiler. Meanwhile, finely chop the nuts. Roast the sunflower seeds and the chopped nuts in a dry pan (without oil). Stir 1 tablespoon margarine into the melted chocolate and stir in the nut mixture.
Knead the dough again and roll out about 0.5 cm thick on a work surface. I always roll out the dough between cling film, nothing sticks and no additional flour is required. Now cut out about 8 biscuits with a 7 cm diameter cookie cutter, the same with a 6 cm round cookie cutter. Place the small biscuits on a parchment-lined baking sheet. Put a little pile of the chocolate and nut filling on top and cover with the larger dough. Press the edges a little hard.
Bake at 180 ° C for about 10 minutes.
Tips:
Instead of wholemeal flour, normal flour can also be used, in which case a little less margarine is required. Refined sugar can also be used instead of raw cane sugar.
