Melt vegan butter or margarine together with sugar and salt.
Add soy milk and sugar beet syrup and mix.
Add baking powder and stir for 2-3 minutes until all lumps are dissolved and the mixture foams well.
Add flour in batches and mix to form a soft, sticky dough.
Place the dough, covered, in the freezer for 30 minutes.
Divide the dough into four equal pieces, roll each piece in flour, and roll each out very thinly on a sheet of baking paper to about the size of the baking sheet (the edges don't have to be straight).
First place one of the four cake layers together with the baking paper on the baking sheet, pierce it several times with a fork and bake it in a preheated oven at 180 °C top and bottom heat for about 5 minutes until lightly golden brown.
Bake the remaining three cake layers in the same way.
While each cake layer is still warm, cut off the uneven edge on all sides and then cut each cake layer into two equal parts so that you have eight cake layers.
Let the cake layers and the cut edges to cool.
Then finely crumble the cut edges.
