Make the flax eggs: mix flaxseed with the water and let it rest for 10 minutes.
Preheat the oven to 180 degrees Celcius or 356 degrees Fahrenheit.
Wisk the soft vegan butter, sugar, vanilla sugar and orange zest to a creamy mass. Little by little add the flax eggs.
Rub the fresh ginger into little pieces, cook it for 5 minutes with 50 ml water and then mix it with a mixer.
Mix flour and cocoa powder and fold it carefully into the butter mass.
Add vegan milk, agave syrup and ginger puree to the mass and fill it all into a piping bag. Form different cookies with a star-shaped noozle on a backing tray with a baking sheet. Bake the cookies in the oven for 8 minutes and then let them cool.
For the orange filling cut the orange into little pieces and cook it slowly for 10 minutes together with 50 ml water and a tbsp gelling sugar. Then mix it in a mixer until it becomes a creamy jam.
