Mix room temperature oil with icing sugar.
Add vanilla sugar and protein, mix well. Pour in flour and knead the dough.
Using a pastry bag, squeeze the dough onto a baking sheet covered with parchment.
For the filling, mix the jam with starch or just take a thick jam. In the cookies, make a deepening and lay out the filling.
Bake in a preheated oven at 220 degrees for 12-15 minutes.
