Combine flour, cocoa powder, pudding powder, baking powder, sugar, vanilla sugar, butter, milk or water, desiccated coconut, and peeled almonds in a bowl and knead into a dough.
Form the dough into 3 to 4 rolls, each approximately 3 cm thick.
Refrigerate the rolls for 1 hour until firm.
Preheat the oven to 200°C (392°F) on the fan/convection setting.
Slice the chilled rolls into 0.5 cm thick slices.
Arrange the slices on a baking sheet, spacing them 2 cm apart, as they will spread during baking.
